DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the field of computer graphics and animation, and particularly includes the case where the motion of an articulated object such as a human or an animal or an elastic object is described as time-series data. The present invention relates to a technique for communicating computer graphics / animation data between computers and generating a computer graphics / animation image on a receiving computer.

2. Description of the Related Art In recent years, multimedia communication via the Internet has been actively performed. Among them, the World-Wide-Web (WWW) forms a central framework. This is described in the literature "Ryusuke Masuoka, Keisuke Kiniwabukuro," World-Wide-Web ", IPSJ Journal, pp1155-1165, Vol.36, No.12.1995."

[0003] Explaining based on the above literature, the central concepts of WWW are URL (Uniform Resource Locators), HTTP (Hy
perText Transfer Protocol), HTML (HyperText Markup L
anguage) and CGI (Common Gateway Interface). URL
Is a notation for uniformly describing various resources on the Internet. HTTP is WWW client and WWW
This is a protocol for communicating with the server. HTML
Is a description language for describing hypertext.
CGI is an agreement on how commands are exchanged between WWW clients and WWW servers.

A mechanism based on these concepts will be described. The WWW client sends the information specified by the URL from the WWW server via the Internet using HTTP.
Obtain it as an HTML document and display it on the screen using a display program called a browser. When the user selects a link on the screen, the URL corresponding to the link
Is specified, the specified information is obtained from the linked WWW server as an HTML document using HTTP via the Internet and displayed on the screen.

The above is the basic operation. In addition, by CGI, for example, HTTP to the WWW server, "GET / cgi-bin / com
When requesting "mand / path HTTP / 1.0", the WWW server sets "/ path" to the environment variable "PATH_INFO" and executes "command." The "command" is executed and output to the standard output. The result can be returned as data to the WWW client that accessed it, and the WWW is now playing a central role in multimedia communication.

However, the above-mentioned HTML has no description specifications for two-dimensional images, and thus cannot handle three-dimensional computer graphics. Under such circumstances, VRML (Virtual Language) is a description language for describing three-dimensional computer graphics as an extension of HTML.
The specification of Reality Modeling Language) was decided in May 1995. For this, see the article "Mark Peace," VRML-B
rowsing and Building Cyberspace ", New RidersPublish
ing, 1995. " The operation is basically HT
As in the case of the ML document, data described in VRML is obtained as information specified by the URL instead of the HTML document.

[0007] In order to display data described in VRML, a dedicated program is required. 3 to be displayed
In the 3D computer graphics image, the viewpoint can be changed, but the VRML description specification (Version 1.0) has no specification for moving the object, so the displayed object is only static.

Under such circumstances, a method has been considered in which three-dimensional computer graphics / animation data is exchanged by communicating between computers and displayed on the client side. As such, for example, ActiveVRML proposed by US Microsoft
And the like. About this ActiveVRML,
crosoft Corporation, "ActiveVRML ReferenceManual",
Preliminary Version, 1995. and Microsoft Corpora
tion, "A Brief Introduction to ActiveVRML", 1995.
It is described in.

However, according to these methods, for movements that can be represented by simple functions, data is exchanged by communicating data between computers, and the data is exchanged on the client side with three-dimensional computer graphics. Although it can be displayed as an animated image, complicated movements of humans and other animals, movements of facial expressions, movements of objects obtained as a result of complex physics calculations, complicated movements of cameras and light sources Can handle
There is a problem that it is very difficult to realize a three-dimensional computer graphics animation that can be reproduced realistically. It is very difficult to express these movements realistically in a functional system, and even if they can be expressed, calculations that require a lot of time are required. Acti
Regardless of veVRML or VRML, since only monocular images are supported, there is a problem that a stereo image of binocular vision cannot be generated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has been made in consideration of a computer graphic in a system including a transmitting computer, a receiving computer, and a communication mediating means between the transmitting computer and the receiving computer.

The display device is an interface between the two.

Embodiment 1 The computer graphics / animation data transmission / reception generation method according to the first embodiment of the present invention will be described in detail below with reference to FIG. 2 based on the system configured as described above. As shown in FIG. 2, the entire process is executed in the first to seventh stages. That is, the first stage is executed in processes 1, 2 and 3, the second stage is executed in processes 4 and 5, the third stage is executed in process 6, and the fourth stage is executed in process 7. , The fifth stage is performed in process 8,
The sixth step is executed in step 9, and the seventh step is executed in steps 10 and 11.

Processing 1 is processing for creating animation data, processing 2 is processing for editing animation data, processing 3 is processing for storing animation data in the storage device 2, and processing 4 is transmission of animation data. , Processing 5 is processing for receiving animation data, processing 6 is processing for storing in the storage device 5, processing 7 is processing for performing initial arrangement of environmental shape data described later, and processing 8 is skeleton at the time. A process 9 for calculating the position and form of the structure, a process 9 for binding the shape data of the object (human) to the skeletal structure, or a process for generating the surface shape data of the object, and a process 10 for rendering with the specified shading method. Processing to be performed,
Process 11 is a process for displaying the rendered computer graphics image on the display device 6, and process 12 is a process for determining whether or not an end command has been issued. Processing 1 to processing 4 are executed by the transmission side computer 1 while using the storage device 2. After the animation data is transferred by the communication mediating means 3, processing 5 to processing 12
The above steps are executed by the receiving computer 4 while using the storage device 5 and the display device 6.

The structure of the animation data created in the above processing 1 is as follows. When a shape is bound to an object, as shown in FIG. , Attribute data, light source data,
Camera parameters, shading method, environment setting, environment management control method, and time-series motion data. When generating the surface shape of an object according to the skeletal structure, FIG.
As shown in (b), the skeletal structure, environmental shape data,
Attribute data, light source data, camera parameters, shading method, environment setting, environment management control method, and time-series motion data. Hereinafter, each item will be described.

First, terms of the skeletal structure will be described. A site in which a plurality of sites (skeleton ends) are connected by a link (three-dimensional vector) is called a segment, and a site in which two sites are connected by a link is particularly called a skeleton (bone). As can be seen from the definition, segments can be broken down into skeletons. The joint between a segment (skeleton) and the segment (skeleton) between sites is called a joint (joint).

A structure described by these segments, skeletons and joints is called a skeletal structure. In order to move the skeletal structure, a local coordinate system (three vectors orthogonal to one point and each other) for determining the position and orientation of the entire skeletal structure is required, and this is called a route. That is,
The position of the route (origin of the local coordinate system) defines the position of the skeleton structure in the overall coordinate system, and the unit vector that defines the coordinate axes of the local coordinate system defines the front, upward, and lateral directions of the skeleton structure. I do. Assuming that the route belongs to one of the segments that define the skeletal structure, the site position (joint position) is defined in a local coordinate system defined for each segment, as described later. Defines the position in the global coordinate system. Therefore, if the route belongs to one of the segments, the sites and joints of the segment can be described in the local coordinate system of the route, so that one less transformation sequence is required than in the case where the route does not belong. Thus, a route may be considered a special one of the site.

The above relationship is shown in FIGS. 7 (a) and 7 (b). As a specific example, FIG. 7C shows a human being represented by a skeletal structure. In FIG. 7C, the skeletal structure is shown hierarchically. Since the number of segments and the number of joints in the upper-layer skeletal structure (coarse model skeletal structure) are smaller than those in the lower skeletal structure (detailed model skeletal structure), the lower-layer skeletal structure (detailed model skeleton) Although it lacks the degree of freedom and smoothness of movement as compared with the structure, the amount of calculation and the amount of time-series motion data for computer graphics / animation are reduced. Therefore, effective use can be achieved by properly using the data amount, the performance of the receiving computer, and the state of animation (when the viewpoint is far). In FIG. 7C, names without parentheses are joint names, and names with parentheses are segment (skeleton) names.

The ends are particularly called end sites. However, since these names are identifiers, they may be encoded as long as they can be identified. Regarding how to write the site name, the joint is defined by two sites from the definition, so when comparing these two sites,
By adding "site 0" to the joint name closer to the route and "site 1" farther away, the site can be named. In FIG. 7 (c), only the right elbow is described, and the others are omitted.

Such a skeletal structure can be described by a tree structure. FIG. 8 shows the structure shown in FIG. 7C in a tree structure. However, in the segment in FIG.
Sites corresponding to joints and end sites are excluded (or are not described because they are used twice). However, the way of illustration of the tree structure adopted here is as follows.

(1) A route and a segment to which the route belongs are determined. (2) The joint is traced from the near side based on the route, and the traced joint is connected by a segment. (3) After reaching the end site, the same operation is repeated for another route that has not been followed.

Since the skeleton structure can be represented by a tree structure, it can be described in the form of a list structure. This description format can be realized by the following processing in the case of one layer. (1) Definition of a segment: A segment name is described, a site name defining the segment and a position vector in its initial state are described. A link is represented by this position vector. The method of expressing this position vector is to display components in a local coordinate system defined for each segment, or to convert a unit vector on a certain axis of the local coordinate system into a position vector of a site (homogeneous coordinate format). Can be done by However, the origin of the local coordinate system is determined to be a site that defines a joint that is close to the route among the sites belonging to this segment (in the case of a segment to which the route belongs, the root is set as the origin). In consideration of dynamics, etc., the mass, the inertia tensor, and the position of the center of gravity may be additionally described. However, in this case, attention must be paid to the definition of the joint angle described later. The description order is desirably from the root of the tree structure to the end (easy to see).

(2) Definition of a joint: A joint name and two site names that define the joint, a joint type and a degree of freedom are defined. The type of joint is
It is divided into a rotary type and a slide type, and the degree of freedom is the number of parameters for rotating and sliding. Since movement in a three-dimensional space is handled, the maximum number of degrees of freedom for each of rotation and slide is three. This degree of freedom is
It also depends on how to define the joint rotation angle described below.

(3) Definition of route: When defining by a site, it is described by a segment name and a site name. Otherwise, describe the closest segment name and site name when following the route from the route, and the position vector of this site in the local coordinate system defined by the route.
It should be noted that the local coordinate system of the route was specified when the position vector of the site was described.
In addition, in order to perform a data load check, the total number of segments, the number of sites, and the number of joints are additionally described.

The description format in the case of multiple hierarchies can be realized by the following processing using the case of the above single hierarchy. (1) Description of the skeletal structure of the parent hierarchy (2) Identifier at the beginning of the description of the child tier (identifier of the description of the detailed skeletal structure) and description of conditions to be used. (3) Definition of child segment: In addition to the description in the case of the single layer, a parent segment name is added. (4) Definition of child joint: Same as the above description format. (5) Root definition: If the root is changed when it is changed to the child hierarchical expression, it is described in the above manner. Otherwise, describe the unchanged identifier. (6) If the hierarchy continues, the processes of (2) to (5) are repeated. However, the parent-child relationship is connected with the immediately preceding hierarchy (description skipping over two or more hierarchies is prohibited).

The skeleton structure is described using the above description format. The specific description is as follows. (1) Description of skeleton structure name (2) Description of specific skeleton structure (above description format). However, if it is described in another file, describe the file name. In addition to the above, when the surface shape of the skeletal structure object is generated in the process 9, the following (3) is additionally described.

(3) The coordinates of the control points of the curved surface for defining the object surface shape generated for each segment are described in the local coordinate system of the segment. At this time, if the control points at the boundary between adjacent segments are shared, a break when the joint operates can be prevented. Alternatively, a curved shape is defined in the joint portion separately from the segment portion in order to prevent the joint portion from being torn (see FIG. 12). Specifically, in the case described above, (segment name) (control point coordinate value sequence),... In the case described below, (segment name) (control point coordinate value sequence)
(Joint name) (radius for control point coordinate value sequence or sphere), ...

Next, the shape data when the object shape is bound to the skeletal structure in process 9 and the shape data of the environment will be described. When binding a surface shape to a skeletal structure, describe the shape of the object to be bound (Fig. 6 (a)).
in the case of). Regardless of the shape of the object to be bound or the shape of the environment, generally in 3D computer graphics, the shape of the object is defined by a polygon (polygon plane), a mesh (triangle mesh, quadrilateral mesh), and a primitive shape. The primitive shape is a shape such as a cube or a sphere, and generally refers to a basic shape having spatial symmetry.

Which object shape is used as a primitive depends on the specification. In addition, the shape of an object may be defined by a curved surface defined by a B-spline, Bezier, or the like, or an energy (potential) boundary surface called a metaball. In the case of a simple shape, the shape is defined in a single hierarchy. At that time, a local coordinate system called an object coordinate system is used. In the case of a complicated figure, the component shape is configured by a local coordinate system determined for each component, and the entire component is configured by a mapping that converts the component into a local coordinate system representing the entire object. If the component itself has multiple layers, the above is repeated.

In the case of the environment shape, the local coordinate system of the part may be appropriate, but in the case of the shape to be bound, the part needs to be defined in the local coordinate system corresponding to the segment of the skeletal structure. If the shape of the object is to be defined by the user, the parts are configured in the local coordinate system of the segment when creating the animation data. When using the shape of a commercially available object (shape of a pre-existing object), a mapping (affine transformation) for transforming a local coordinate system originally used to a segment local coordinate system when editing animation data. Ask for. The method of calculating this conversion is to specify where in the segment the representative points (9 or more) of polygons and meshes that make up the shape of the part are to be placed, and to solve simultaneous equations that represent the correspondence with the original positions. Can be obtained by

A specific example of how to describe the shape of an object will be described below. (1) Description of the name of the whole object shape. (2) Description of the name of the part shape. (3) Described by the above-mentioned components such as polygons and meshes constituting the component shape. Specifically, in the case of a polygon or a mesh, it is a sequence of three-dimensional coordinate values of vertices and nodes. However, if it is described in another file, describe the file name. In the case of a primitive, the primitive name, the coordinates of the center position (representative position), and the scale conversion amount are described.

Each constituent shape describes corresponding attribute data and mapping coordinates. However, in the case of a primitive shape, since the mapping coordinates can be fixed, it is unnecessary when the mapping coordinates are fixed. Finally, a transformation matrix to the local coordinate system representing the whole part is described. However, in the case of the shape to be bound, the name of the segment to be bound is described instead of this transformation matrix.

(4) The above processes (2) and (3) are repeated as necessary. When the skeletal structure is operated, the bind shape causes a tear at the joint. As a method for preventing this, it is preferable to arrange a primitive shape such as a sphere at the joint (see FIG. 11).
This may be automatically added at the time of drawing by the passive computer, or may be explicitly given beforehand.
In that case, (5) a joint name, a primitive shape name to be arranged there, and a scale amount are additionally described. However, it is assumed that the binding to the joint defines a point (for example, the center of gravity) inside the primitive corresponding to the joint position. As another method for preventing tearing, there is a method in which the boundary of the component shape bound to the two segments is made variable, and the boundary is changed in accordance with the change of the joint to be surely connected.

In addition, when it is desired to use both the outline description and the detailed description, the following description is used. (1) Description of the name of the whole object shape. (2) Description of the name of the general part shape. (3) Described by the above-mentioned ones such as polygons and meshes constituting the outline part shape. Specifically, in the case of a polygon or a mesh, it is a sequence of three-dimensional coordinate values of vertices and nodes. In the case of a primitive shape, the name of the primitive shape, the coordinates of the center position (representative position), and the scale conversion amount are described. Each component shape describes corresponding attribute data and mapping coordinates. However, in the case of a primitive shape, since the mapping coordinates can be fixed, it is unnecessary when the mapping coordinates are fixed.

Finally, a transformation matrix to the local coordinate system representing the whole part is described. However, in the case of the shape to bind,
Describe the segment name to be bound instead of this transformation matrix. (4) Identifier of detailed description and description of usage conditions. (5) Description of the name of the detailed part shape. (6) Description of the configuration of the detailed part shape (similar to (3) above). (7) Steps (2) to (6) are repeated as necessary. Described as attribute data are the reflectance (specular component, diffuse component), transparency, texture data (color data distribution), bump data (normal vector component distribution or displacement component amount distribution) and illuminance distribution of the object. It is. The reflectance and the transparency may be given as constants or distributions, and may be given for each color of the light source (RGB, YCbCr, etc.). This also includes the mask data for the distribution type data.

The specific description is as follows. (1) Description of data name or identifier. (2) Data type description. (3) Description of distribution type and distribution size. For a constant,
The size is 1 in a rectangular distribution. The type of distribution is based on the basic shape such as rectangular distribution or triangular distribution. (4) Data (column) description. For example, in the case of a rectangular distribution, it is described in a matrix format. However, if it is described in another file, describe the file name.

As the light source data, the initial position and the light source intensity and the attenuation rate for the point light source, the initial position of the end point for the line light source, the direction vector, the light source intensity, the attenuation rate, the length, and the surface light source Initial position of representative point, normal vector, light source intensity,
Give the attenuation rate, shape definition and area. When each light source has a light distribution, a light distribution other than the above is provided.

The specific description is as follows. (1) Description of light source name or identifier. (2) Description of the type of light source. (3) Description of initial position. (4) Description of light source intensity. (5) Description of attenuation rate. (6) In the case of a linear light source, a direction vector, a length, and in the case of a surface light source, a normal vector, a shape definition (shape name or vertex coordinates), and an area are described. (7) If the light distribution is provided, describe the light distribution. However, if it is described in another file, describe the file name.

As the camera parameters, an initial position, an initial line-of-sight vector, an upper vector (a vector indicating the upward direction of the camera), a focal length, and an angle of view are described. The specific description is as follows. (1) Description of camera name or identifier. (2) An initial position, an initial line-of-sight vector, an upper vector (a vector indicating the upward direction of the camera), a focal length, and an angle of view are described.

As a shading method, a specific shading algorithm name (or identifier) at the time of rendering is described. That is, names such as wire frame, flat shading, glow shading, phone shading, ray tracing, and illuminance mapping, or identifiers corresponding thereto are described. However, in the case of illuminance mapping, it can be used only when an illuminance distribution is given as attribute data. Multiple descriptions can be given with priorities.

The priorities are assigned to the processing times so that they can be properly used according to the performance of the receiving computer.

The environment setting is data for performing initial arrangement of the environment shape, and is described by an affine matrix. The specific description is as follows. (1) Describe the name or identifier of the shape object in the environment. (2) Describe an affine transformation matrix. (3) The processes of (1) and (2) are repeated for the number of shaped objects in the environment.

In the environmental management control method, an object (a skeletal structure)
Exercise management. However, when the light source and the camera also move, the management is also performed. The specific description is as follows. (1) Description of the name or identifier of a skeletal structure (light source, camera). (2) Description of the name of the corresponding time-series motion data. However,
If it is stored in another file, the file name is also added. (3) The processes of (1) and (2) are repeated for the number of skeletal structures (light sources, cameras).

Next, the time-series motion data will be described. The time-series motion data basically describes the movement of the skeletal structure, but also describes the movement of the camera and the light source.

In the case of a skeletal structure, when the link length is fixed, it is composed of time series data of the affine transformation of the root and time series data of the joint angle (rotation amount).
If it is not fixed, it is necessary to add time-series data relating to a link as described later. The time-series data of the affine transformation of the route includes a route position, that is, a position where the entire skeleton structure exists, and a rotation amount, that is, a posture control amount of the entire skeleton structure. For the root position, three-dimensional coordinate values (three-dimensional position vector) in the world (whole) coordinate system
Give in. Regarding the amount of rotation, there are various ways to give the same as with the joint angle. First, typical joint angles (rotation amounts) will be described with reference to FIG. 9, and then the rotation amounts of the routes will be described.

FIGS. 9 (a) and 9 (b) show that the local coordinate system defined by each segment is parallel to the local coordinate system of the route (that is, the unit vector of each of the x, y, and z axes is the link). This is the joint angle (the amount of rotation) used in the case of coincidence. In FIG. 9 (a), a rotation amount is given to the initial state of the skeletal structure so that when the link is rotated around the x-axis, the y-axis, and the z-axis, the link state becomes the current time. Alternatively, with respect to the state of the skeleton structure at the immediately preceding time, a rotation amount is given so that when the link is rotated around the x-axis, the y-axis, and the z-axis, the link state becomes the current time. Since the amount of rotation changes depending on the order of rotation, the order of rotation also needs to be defined. FIG. 9 (b) is based on a polar coordinate display, in which the rotation amount of the link around the z-axis and the link and z
It is given by the angle with the axis. In both methods, if the link length is not fixed, it is necessary to provide time-series data of the link length at each time or time-series data of the amount of change in the link length from the immediately preceding time.

When the joint angles (rotation amounts) are given in FIGS. 9 (c) and 9 (d), all segments must be composed of skeletons. In this case, FIG. 9 (c) gives the values in Euler angles, and FIG. 9 (d) gives the values in yaw, low and pitch. In each case, the initial state of the link
Time-series data is given in terms of Euler angles, yaw, low, and pitch angles for setting the current link state. However, in this case, in the initial state, one of the axes in the local coordinate system of the segment coincides with the link (FIG. 9C,
(The z axis is the same in (d).), and the local coordinate system moves like the link at each time. Therefore, the position of the site displayed in this local coordinate system is unchanged if the link length is fixed. If the link length is not fixed, it is considered that the joint is sliding in addition to the rotation of the joint (so-called slide joint in robotics). As another method of giving the joint angle (the amount of rotation), there is DH (Denavit-Hartenberg) notation, which is famous in the field of robotics. However, in each method, the angle is determined according to the degree of freedom of each joint (3 degrees of freedom if all rotations are possible). Also, since each rotation amount changes depending on the order of rotation, it is necessary to define the order.

The rotation amount of the route is given by the method shown in FIG. 9A or 9B. In other words, when the global coordinate system is translated in such a manner that the origin overlaps the local coordinate system defined by the route, the x-axis and the y-axis where the global coordinate system coincides with the local coordinate system of the route, as shown in FIG. It is given as the amount of rotation in the rotation conversion about the axis and the z axis. In the case of FIG. 9B, the amount of rotation of each axis of the local coordinate system of the route with respect to the entire coordinate system around the z-axis and the amount of rotation of the route with the angle formed with the z-axis are given.

As described above, the time-series motion data for the skeletal structure is composed of the above-described vector amount for the route and the vector amount for the segment. There are two methods for describing the data. (1) All the above vector quantities are described for each time. (2) Each vector amount is described over all times. Since drawing is performed at each time, in view of data loading, in the case of (1), access to a localized area is sufficient, but in the case of (2), access to an area that is somewhat dispersed is sufficient. Become. From that point, it is considered that the description method (1) is superior.

What is given as time-series motion data for the motion of the camera is a (3 + 3 + 3) -dimensional vector describing the camera position, line-of-sight vector, and upper vector at each time, or an affine transformation matrix, focal length, and angle of view. Thereby, it is possible to simulate a camera work superior to a so-called motion control camera. What is given as the time-series motion data for the movement of the light source can basically be given for all the data relating to the light source described above. Although it depends on the purpose, for example, in the case of a point light source, a moving light source object such as a firefly or a luminous insect can be expressed by giving the position and the light source intensity at each time.

As can be seen from the above, a specific description of the time-series motion data will be made as follows. (1) Description of time-series motion data name (2) Description of motion type (skeletal structure, camera, light source) (3) Description of vector amount for each time. However, a name and an identifier indicating what (eg, a segment name, a camera position, an angle of view, etc.) is a vector amount are additionally described. When data formats are mixed, an identifier for the data format (vector size or matrix size) is also added.

The creation of the actual time-series motion data is performed by forward, reverse kinematics, forward, reverse dynamics, motion optimization calculation, motion capture, and the like. In the case of a long time motion, the time-series motion data is created by combining a plurality of various motions (see FIG. 10A). The animation data is described for each item in an area where the item can be identified (an area surrounded by a start identifier and an end identifier) or in a file with a file name indicating the item.

In process 2, the animation data is edited. Here, the editing means confirmation for performing a target computer graphics animation and adjustment of data. Editing of the object shape to be bound to the skeletal structure is as described above. Regarding the shape of the environment, confirm that the desired environment shape has been created, or check that the environment has been arranged according to the environment settings, and make timely corrections. Regarding time-series motion data, especially in the case of long-time motion, as described above, time-series motion data is created by combining a plurality of various motions. Check whether it is correct and correct it as needed. At the time of these confirmations, confirmation of the attribute data light source data, camera parameters, shading method, environment setting, and environment management control method is also performed at the same time.

In the process 3, the animation data that has been checked and corrected is stored in the storage device 2. In processing 4 and processing 5, the animation data stored in the storage device 2 is transmitted and received. Since transmission and reception can be performed by http or ftp, the transmission and reception are performed from the transmitting computer 1 to the receiving computer 4 via the communication mediating means 3 in accordance with the format of the protocol. In process 6, the received animation data is stored in the storage device 5 of the receiving computer 4.

The processing from the processing 7 to the processing 12 is performed by the computer graphics
This is for generating an animation image. The description is given below. In process 7, the shape object of the environment to be processed is determined based on the name or identifier of the environment shape object described in the environment setting of the animation data. The converted environment shape data is arranged at a predetermined position in the world (whole) space. In other words, although it is spatially arranged,
The actual processing is coordinate transformation. The above processing is performed on the shape objects in all environments, and the converted data is temporarily stored in the storage device 5.

In the process 8, the skeletal structure (light source, camera) to be processed is determined from the name or identifier of the skeletal structure (light source, camera) described in the animation data environment management control method. The vector amount (state data) of the skeletal structure (light source, camera) at the time is read from the described time-series motion data name or the time-series motion data indicated by the file name.
In the case of a skeletal structure, movement (conversion) to the position at the time is performed based on the read vector amount,
The state changes to the skeleton state (posture) at the time. This is performed based on the conversion relationship between the local coordinate system defined for each segment and the world (whole) coordinate system, and the conversion relationship between the local coordinate systems. In the case of the light source (camera), the light source (camera) is moved to the position at the time described in the time-series motion data and changed to the light source (camera) parameter at the time. The data obtained above is temporarily stored in the storage device 5.

In processing 9, the corresponding object shape is bound or the surface shape of the object is generated in accordance with the position and the skeletal state (posture) of the skeletal structure at the time stored in the storage device 5. I do. When binding the object shape, the whole (world) coordinate system used when calculating the position and the skeleton state (posture) of the skeleton structure using the part shapes grouped for each segment as shown in FIG. And a transformation of the local coordinate system, and a transformation sequence between the local coordinate systems.

Also, as shown in FIG. 11, the shape of a sphere or the like is bound to the joint portion, thereby closing the fracture of the component shape. In the case of a sphere, a sphere is generated with a radius centered on the joint position and determined by the part shape and the movable range of the joint (or a sphere defined in the object coordinate system is affine-transformed). The data of the bound object shape (converted data) is temporarily stored in the storage device 5.

In the case where the surface shape of an object is generated, as described above, a control point for generating a curved surface of a part defined for each segment added to the skeleton structure of the animation data is defined by a local coordinate system. Is converted into a global (world) coordinate system and a conversion series between local coordinate systems, and a curved surface is generated based on the converted control points.

The generated curved surface is classified into a case where it is used as it is and a case where it is used as a mesh approximating the curved surface. If the surface is a curved surface, the amount of calculation increases, which is not very common, and the rendering method is also limited (method similar to ray tracing). In a method of generating a mesh from control points, two parameters defining a surface equation are discretized to the number of nodes to be generated, and the discrete values are substituted into the surface equation to find a corresponding point on the surface. This point may be used as a node of the mesh. If control points are shared between segments, mesh (surface) for all segments
Is stored in the storage device 5. When a shape for preventing the joint portion from being torn is generated, the shape is also stored in the storage device 5. However, the manner of occurrence is the same as in the case of the segment. FIG. 12 is a diagram schematically showing the above processing results.

In the process 10, according to the shading method described in the animation data, the layout data of the environment shape, the light source data, the camera data, the shape data of the bound object, or the surface shape data of the generated object once stored in the storage device 5. Is used to generate an image at the time. Rendering is performed in the same way as normal computer graphics. The generated image data is color data (RGB) for each pixel.
Value). The generated image data is temporarily stored in the storage device 5. In the process 11, the image data stored in the storage device 5 is displayed on the display device in the same manner as that usually performed by computer graphics.

In the process 12, it is determined whether or not the end command has been issued. The end instruction is from processing 8 to processing 1
1, and when it is issued, an interrupt process is performed, and an identification symbol indicating the effect is assigned to an area provided in the storage device 5. By looking at this identification symbol, it can be determined whether or not the end command has been issued. If it is determined in step 12 that the end command has been issued, the process is terminated. If not, steps 8 to 12 are repeated. In order to perform the computer graphics / animation infinitely without a sense of incongruity, the time-series motion data may be cycled (the beginning and the end are the same; the cycle is the length of the time-series motion data).

Embodiment 2 Next, a method for transmitting and receiving computer graphics / animation data according to the second embodiment of the present invention will be described in detail with reference to FIG. As shown in FIG. 3, the entire process is performed in the first
The steps are executed from the ninth stage. That is, the first stage is executed by the processes 21, 22 and 23, the second stage is executed by the processes 24 and 25, the third stage is executed by the process 26, and the fourth stage is executed by the process 27. , The fifth step is performed in step 28, the sixth step is performed in step 29,
The seventh step is executed in steps 30 and 31, the eighth step is executed in step 32, and the ninth step is executed in steps 33 and 34.

The process 21 is a process for creating animation data, the process 22 is a process for editing the animation data, the process 23 is a process for storing the animation data in the storage device 2, and the process 24 is a process for transmitting the animation data. 25, a process for receiving animation data, a process 26, a process for storing data in the storage device 5, a process 27, a process for initial placement of environmental shape data, and a process 28, a process in which the time corresponds to the basic action period. Processing for determining whether the time is within the connection period or within the connection period, processing 29
Is a process of calculating the position and form of the skeletal structure at the time when it is determined to be within the basic action period, a process 30 is a process of generating a connection action when it is determined to be within the connection period, and a process 31 is within the connection period. When it is determined that the position and form of the skeletal structure at the time are calculated, the process 32 is a process of binding shape data of an object (human) to the skeletal structure, or a process of generating surface shape data of the object. 33 is a process for performing rendering by the designated shading method, process 34 is a process for displaying the rendered computer graphics image on the display device, and process 35 is a process for determining whether or not an end command has been issued.

Further, the above-mentioned processes 21 to 24 are executed by the transmitting computer 1 using the storage device 2. After the animation data is transferred by the communication mediating means 3, the processes 25 to 35 are performed by the receiving computer 4. , Using the storage device 5 and the display device 6.

The structure of the animation data created in the above process 21 is as follows when the shape is bound to the object.
As shown in FIG. 6C, the skeleton structure, the shape data to be bound, the environment shape data, the attribute data, the light source data,
Camera parameters, shading methods, environment settings, environment management control methods, basic actions, action rules, and time-series basic motion data. When the surface shape of the object is generated according to the skeleton structure, as shown in FIG. 6D, the skeleton structure, environment shape data, attribute data, light source data, camera parameters, shading method, environment setting , Environmental management control method, basic action, action rule, and time-series basic motion data.

The skeleton structure, the shape data to be bound, the shape data of the environment, the attribute data, the light source data, the camera parameters, the shading method, and the environment setting are the same as those in the first embodiment described above. The explanation is omitted, and the basic behavior, the behavior rule, the time-series basic motion data, and the environmental management control method are described.

The basic action is a movement which is a unit when a series of movements of the skeletal structure are divided. For example, sitting, standing, walking, kicking and the like are called basic actions, and can be distinguished by a name or an identifier. Since the division into these basic actions is an empirical division, the division unit differs to some extent depending on the user, but in the following processing, there is no dependency on the division unit (division method). I do not care. The basic action has a one-to-one correspondence with the time-series basic motion data, and a description of the correspondence is a description of the basic action. The action time of the basic action (time-series basic motion data) is also added. The specific description is as follows. (1) Description of name or identifier of basic action. (2) Description of the name or identifier of the corresponding time-series basic motion data. (3) Description of the time (basic action time) of the time-series basic motion data. (4) The processes from (1) to (3) are repeated by the number of basic actions.

Note that it is convenient for management to specify the number of all basic actions at the beginning of the sentence.

The action rules describe a sequence combining these basic actions and a connection time between the basic actions when the skeletal structure actually acts. The specific description is as follows. (1) Description of identification number and name or identifier of first basic action. (2) Description of the identification number, the connection time (the number of connection frames) of the first basic action and the second basic action. (3) Description of the identification number and the name or identifier of the second basic action. The time-series basic motion data is, as can be understood from the above description, a temporally short (unitized) version of the above-described time-series motion data corresponding to the basic action. It is exactly the same as for data.

The above basic actions, action rules, and time-series basic motion data can be applied to a light source and a camera. The environmental management control method manages the motion of an object (skeletal structure). However, when the light source and the camera also move, the management is also performed. The specific description is as follows. (1) Description of the name or identifier of a skeletal structure (light source, camera). (2) Description of the name of the corresponding action rule. However, if the file is stored in another file, the file name is also added. (3) The processes of (1) and (2) are repeated for the number of skeletal structures (light sources, cameras).

In step 22, the animation data is edited. Here, the editing means confirmation for performing a target computer graphics animation and adjustment of data. Editing of the object shape to be bound to the skeletal structure is as described above. Regarding the shape of the environment, confirm that the desired environment shape has been created, or check that the environment has been arranged according to the environment settings, and make timely corrections. With regard to basic actions, action rules, and time-series basic motion data, adjustment of the combination of basic actions, adjustment of connection time, and confirmation of whether or not a desired action is being performed are corrected as appropriate. At the time of these confirmations, confirmation of attribute data, light source data, camera parameters, shading method, environment setting, and environment management control method is also performed at the same time.

In the process 23, the process is performed in the same manner as the process 3 in the first embodiment of the present invention. Steps 24 and 25 are performed in the same manner as steps 4 and 5 of the first embodiment of the present invention. Process 26
Is performed in the same manner as in the processing 6 of the first embodiment of the present invention.

The processing from processing 27 to processing 35 is as follows:
The receiving computer 4 generates computer graphics / animation images. The description is given below. The process 27 is performed in the same manner as the process 7 of the first embodiment of the present invention.

In process 28, the skeleton structure (light source, camera) to be processed is determined from the name or identifier of the skeleton structure (light source, camera) described in the environment management control method of the animation data. It is determined whether the object is within the basic action period or the connection period at the time. The determination was made based on the connection time indicated in the action rule of the action rule name described after the skeletal structure name in the environmental management control method and the connection time indicated in the basic action of the basic action name described in the action rule Start with the basic action time. Specifically, the i-th basic action time of the skeletal structure is represented by Bti
(i = 1, 2,...), the connection time between the i-th basic action and the (i + 1) -th basic action is Cti (i = 1, 2,...), and The procedure is as follows.

(1) The maximum n (n = 1, 2,...) Satisfying Bt1 + Ct1 +... + Btn + Ctn ≦ T is determined. (2) If n exists in (1), dT = T− (Bt1 + Ct1)
+ ... + Btn + Ctn). (3) If dT ≦ Btn + 1 in (2), the time is the
The state at time dT within the n + 1 basic action period. However, it is assumed that each basic action starts from time 0. (4) If Btn + 1 <dT in (2), the time T is the
Time dT during the connection period between the n + 1 basic action and the n + 2th basic action
-Btn + 1 state. However, it is assumed that each connection operation starts from time 0. (5) When n does not exist in (1), (5-1) dT ≦ Bt
If 1, the time is the state of time dT within the first basic action period. (5-2) If Bt1 <dT, the time is the state of time dT-Bt1 in the connection period between the first basic action and the second basic action.

Note that the above (1) is the maximum n obtained by holding the identification number of the completed connection period for each skeletal structure. However, the identification number starts from 1, the initial state of the holding area is 0, and the held identification number is 0.
In this case, it is determined that the maximum n to be found does not exist. The time during the basic action or the connection period is temporarily stored in the storage device 5.

In the process 29, when it is determined in the basic action period in the process 28, the vector amount (state data) of the skeletal structure (light source, camera) at the time is read from the corresponding time-series basic motion data. . At the time of reading, the time in the basic action stored in the storage device 5 is used. In the case of a skeletal structure, movement (conversion) to the position at the time according to the read vector amount
Then, the skeleton state (posture) at that time is transformed.
This is performed based on the conversion relationship between the local coordinate system defined for each segment and the world (whole) coordinate system, and the conversion relationship between the local coordinate systems. In the case of the light source (camera), the light source (camera) is moved to the position at the time described in the time-series motion data and changed to the light source (camera) parameter at the time. The obtained data is temporarily stored in the storage device 5.

In the process 30, if it is determined in the process 28 that the current time is within the connection period, a connection operation is generated. A method of generating a connection operation will be described with reference to FIG. The time-series basic motion data corresponding to the basic actions before and after the connection operation to be obtained are referred to as pre-basic motion data and post-basic motion data. It is assumed that all the basic motion data is time ts and the connection time is te-ts. Therefore, the subsequent basic motion data starts at time te. It is assumed that each time-series basic motion data starts at time 0, and the subsequent basic motion data is translated by te with respect to time. Under this assumption, a connection operation is generated in the following procedure.

(1) Backward prediction up to time te is performed using the latter half of the previous basic motion data. This prediction is performed for each component of the vector amount, and is obtained by interpolating the data in the latter half. The interpolation uses a polynomial interpolation such as a spline interpolation, a Chubitschev polynomial that defines a trigonometric function, or the like. Let the prediction curve of component i be Ai (t). (2) Time using the first half of the basic motion data
Make a forward prediction up to ts. This prediction is also performed for each component of the vector quantity, and is obtained by interpolating the data in the first half. Let the prediction curve of component i be Bi (t).

(3) When the time ts is 1, the time te is 0, and the monotonically decreasing and differentiable function is φ (t), the time series connection motion data of the connection operation from the time ts to the time te is represented by Ai (t) Obtained for each component by φ (t) + Bi (t) (1-φ (t)). As specific φ (t),
For example, there is φ (t) = (1 + cos (π (t-ts) / (te-ts))) / 2. (3) is 0 at time ts, 1 at time te, and a monotonically increasing and differentiable function is φ (t).
, The time-series connection motion data of the connection operation at time te may be obtained for each component by Ai (t) (1−φ (t)) + Bi (t) φ (t). As a specific φ (t), for example, φ (t) = (1-cos (π (t-ts) / (te-ts))) / 2. In addition, if it is determined in the process 28 that the connection operation is within the connection period, the connection operation is continued during the time te-ts, so that the connection operation is generated only when the operation enters the period for the first time.
It is also possible to generate time-series connection operation data until the connection operation is completed, hold the data in the storage device 5, and read out from the storage device 5 for the second and subsequent times without generating the connection operation. Furthermore, the forward prediction curve and the backward prediction curve
Since each time-series basic motion data is fixed, if only the maximum value of the connection time is calculated and held in advance, it is not necessary to calculate the prediction curve every time the connection is made.

In the process 31, in the case of the skeleton structure, the connection operation generated in the process 30 is moved (converted) to the position at the time and transformed to the skeleton state (posture) at the time. This is performed based on the conversion relationship between the local coordinate system defined for each segment and the world (whole) coordinate system, and the conversion relationship between the local coordinate systems.
In the case of the light source (camera), the light source (camera) is moved to the position at the time described in the time-series motion data and changed to the light source (camera) parameter at the time.
The data obtained above is temporarily stored in the storage device 5.

In the process 32, the corresponding object shape is bound or the surface shape of the object is generated according to the position and the skeletal state (posture) of the skeletal structure at the time stored in the storage device 5. I do. This processing is performed in the same manner as in the processing 9 of the first embodiment of the present invention. In the process 33, by using the shading method described in the animation data, the arrangement data of the environmental shape, the light source data, the camera data, the shape data of the bound object, or the surface shape data of the generated object are stored once in the storage device 5. , Rendering to generate an image at the time. This processing is performed in the same manner as processing 10 described in the first embodiment of the present invention.

In the process 34, the image data stored in the storage device 5 is displayed on the display device in the same manner as that usually performed by computer graphics. In the process 35, it is determined whether or not the end command has been issued. This processing is performed according to the first embodiment of the present invention.
The processing is performed in the same manner as the processing 12 indicated by. If the end command has not been issued, steps 28 to 35 are repeated.
In order to perform computer graphics and animation indefinitely without discomfort, the basic actions described in the action rules should be cycled (the beginning and end should be the same. The cycle is the total time of the time series basic motion data and the connection operation) )

Embodiment 3 Next, a method for transmitting and receiving computer graphics / animation data according to the third embodiment of the present invention will be described in detail with reference to FIG. As shown in FIG. 4, the entire process is performed in the first

Further, the above processing 41 to processing 44 are executed by the transmitting computer 1 using the storage device 2, and after the animation data is transferred by the communication mediating means 3, the processing 45 to processing 56 are performed by the receiving computer 4. , Using the storage device 5 and the display device 6.

The configuration of the animation data created in the process 41 is as follows when binding a shape to an object.
As shown in (c), skeleton structure, shape data to bind, shape data of environment, attribute data, light source data, camera parameters, shading method, environment setting, environment management control method, basic behavior, behavior rules, time series Basic motion data.

The shape data to be bound, the shape data of the environment, the attribute data, the light source data, the camera parameters, the shading method, the environment setting, the basic action, and the time-series basic motion data are the same as those described in the second embodiment. Since they are the same, the description is omitted here, and the skeletal structure, action rules, and environmental management control method will be described.

Regarding the skeletal structure, in addition to the skeletal structures in the first and second embodiments, items relating to sensing with respect to the outside world are additionally described. Sensors provide for vision and for tactile sensation. For vision, a three-dimensional area, such as a sphere or a fan-shaped combination of a great circle of spheres, centered on a part corresponding to an eye (site) is defined as a sensing area. As for the tactile sensation, a sphere region around a site such as a hand is defined as a sensing region. Therefore, the following description is specifically added to the description of the skeletal structure in the first and second embodiments. (A) Description of sensor type (visual or tactile) identifier. (B) Description of central site name. (C) Description of area definition. The action rule describes the state transition between these basic actions, the event that causes the state transition, and the connection time of the connection operation at the time of the state transition when the skeletal structure actually acts by combining the basic actions. Here, the event includes an event related to sensing of the skeletal structure described above and an event caused by an external input such as a mouse or a keyboard.

FIG. 13 shows an example of a state transition diagram of the basic action. The description of the action rule describes this state transition diagram. The specific description is as follows. (1) Description of the name or identifier of the first basic action. When no event occurs, a type identifier indicating whether the basic action is a type of a basic action that is in a state of waiting while repeating the basic action or a type of a basic action that unconditionally transitions to another basic action is also added. (2) State transition description. (2-1) Description of event identifier. (2-2) Description of the name or identifier of the basic action at the transition destination after the occurrence of the event. If the destination is a type of basic action that unconditionally transitions to another basic action, the name or identifier of the return basic action is also described.

(1) Description of the name or identifier of a skeletal structure (light source, camera). (2) Description of the name of the corresponding action rule. However, if the file is stored in another file, the file name is also added. (3) Description of event identifier to be used.

(4) The processes of (1) to (3) are repeated by the number of skeletal structures (light sources, cameras). (5) A description of an event identifier and a condition for determining the occurrence of the event. Describe all events.

In the process 42, the animation data is edited. Here, the editing means confirmation for performing a target computer graphics animation and adjustment of data. Editing of the object shape to be bound to the skeletal structure is as described above. Regarding the shape of the environment, confirm that the desired environment shape has been created, or check that the environment has been arranged according to the environment settings, and make timely corrections. For basic actions, action rules, and time-series basic motion data, adjustment of combinations and transitions of basic actions, adjustment of connection time, and confirmation of whether or not a desired action is being performed are corrected as needed.
At the time of these confirmations, confirmation of attribute data, light source data, camera parameters, shading method, environment setting, and environment management control method is also performed at the same time.

Processing 43 is processing 3 of the first embodiment described above.
Perform in the same manner as described above. Processing 44 and processing 45 are performed in the same manner as processing 4 and processing 5 described in the first embodiment. The process 46 is performed in the same manner as the process 6 described in the first embodiment. The processing from the processing 47 to the processing 56 is for generating a computer graphics / animation image in the receiving computer 4. The description is given below.

Processing 47 is performed in the same manner as processing 7 shown in the first embodiment. In the process 48, a process relating to detection of occurrence of an event and a state transition of a basic action is performed. As a premise of the processing, it is assumed that an area for writing the current state is secured in the storage device 5 for each skeletal structure. In this area, when the current state is performing a basic action in a loop, the name or identifier of the operating basic action and the time of the current state in the time-series basic motion data are held. In the case of, the identifier indicating the transition, the names or identifiers of the basic actions before and after the transition, the transition start time, and the connection time are held. The writing of the transition is performed from the time immediately after the occurrence of the event.

However, when a transition is made to a basic action of a type that unconditionally shifts to another basic action, an identifier indicating that the transition is in progress (an identifier different from the one described above), the original basic action, and the basic action to be passed on The name or identifier of the post-transaction basic action,
The connection time before and after the passing basic action is held, and the transition from immediately after the occurrence of the event (the relevant time) to the transition to the basic action after the passing is defined as transition.

As for the detection of an event, first, all the conditions for determining the occurrence of an event described in the environment management control method of animation data are checked, a corresponding event is found, and the event identifier is held. The skeleton structure (light source, camera) and action rule corresponding to the held event identifier are found from the description of the environmental management control method, and the name or identifier of the action rule is held. Next, the transition of the basic behavior is performed by looking at the behavior rule corresponding to the name or identifier of the retained behavior rule. This processing is performed by the storage device 5, and the result is written and held in the above-mentioned area indicating the current state provided for each skeletal structure. For a skeletal structure whose current state is transitioning, occurrence of an event is ignored.

In the process 49, it is determined whether the skeleton structure (light source, camera) to be processed is within the basic action period or the connection time at the time T. This determination is made by looking at the current state provided for each skeletal structure described above. Those that are not in a state transition are determined to be within the period of the held basic action. For a skeletal structure that is undergoing a state transition, it is determined whether or not a transition is being made to a basic behavior of a type that unconditionally transitions to another basic behavior. To Ct0 and the transition start time to T
s, when the time is T, it is determined that the state is T-Ts during the connection period. In particular, when T = Ts + Ct0, the identifier of the basic action during transition of the area indicating the current state is changed to the name or identifier of the destination basic action, the current time in the time-series basic motion data is set to -1, and the determination is made. Change the results within the basic action period.

In the case of transition to a basic action of a type that unconditionally shifts to another basic action, the operation time of the basic action to be passed is set to
Bt, the connection time before and after that is Ct0, Ct1, the transition start time is Ts, and the time is T (Ts <T ≦ Ct0 + Bt + Ct1). (1) If T <Ts + Ct0, the state at time T-Ts during the connection period of the outgoing connection operation. However, it is assumed that each connection operation starts from time 0. (2) If Ts + Ct0 ≦ T <Ts + Ct0 + Bt, the state at time T− (Ts + Ct0) during the basic action period. However, it is assumed that the basic action starts from time 0. (3) If Ts + Ct0 + Bt ≦ T ≦ Ts + Ct0 + Bt + Ct1, the state at time T− (Ts + Ct0 + Bt) during the connection period of the return connection operation. In particular, when T = Ts + Ct0 + Bt + Ct1, change the identifier in transition of the area indicating the current state to the name or identifier of the basic action after passing, and indicate the current state in the time-series basic motion data The time is set to -1, and the determination result is changed within the basic action period.

In the process 50, when it is determined in the process 49 that it is within the basic action period, the vector amount (state data) of the skeletal structure (light source, camera) at the time is read from the corresponding time-series basic motion data. . The reading method is
The vector amount at the time obtained by adding 1 to the current time secured for each basic action stored in the storage device 5 is read from the corresponding time-series basic motion data. After reading, update the current time. If the current time exceeds the time at which the time-series basic motion data has the maximum value, the vector amount is set to 0 (the remainder at the time at which the maximum value becomes the time + 1). This enables a toggle operation. In the case of a skeletal structure according to the read vector amount, the skeleton structure is moved (converted) to the position at the time and deformed to the skeletal state (posture) at the time.

This is performed based on the conversion relationship between the local coordinate system defined for each segment and the world (whole) coordinate system, and the conversion relationship between the local coordinate systems. In the case of the light source (camera), the light source (camera) is moved to the position at the time described in the time-series motion data and changed to the light source (camera) parameter at the time. The data obtained above is temporarily stored in the storage device 5.

In the process 51, when it is determined in the process 49 that it is within the connection period, a connection operation is generated as necessary. In other words, as described above, if it is determined that a transition is being made by a basic action of a type that unconditionally moves to another basic action,
It is not necessary to generate a connection operation during the basic action to be passed, and time-series basic motion data corresponding to the basic action to be passed is used. The algorithm for generating the connection operation is basically the same as the processing 30 shown in the second embodiment, except that it is necessary to connect to the subsequent basic motion data in the middle of the previous basic motion data. That is to say. Therefore, the method of generating the backward prediction curve is different.

Now, the time when the previous basic motion data becomes maximum is
It is assumed that a connection operation needs to be generated at ts, connection time tc, and time T ≦ ts. At this time, (1) If T = ts, the process is the same as the process 30 of the second embodiment. (2) If tc ≦ ts-T, the previous basic motion data for tc from time T (remaining data that has not been executed) is used as the backward prediction curve. (3) If ts-T <tc, the previous basic motion data from time T to ts and the backward prediction curve generated by the method of processing 30 in the second embodiment for the time tc- (ts-T) Are used in combination.

As the forward prediction curve, a curve calculated in advance can be used as described in the processing 30 in the second embodiment. If the event processing is not performed in the middle of the previous basic motion data (that is, the connection processing is performed after the completion of the previous basic motion data), the method is exactly the same as the processing 30 shown in the second embodiment. Generate a connection curve.

In the process 52, from the connection operation generated in the process 51 (time-series basic motion data corresponding to the basic action to be passed when passing), the process moves to the position at the time when the frame is a skeletal structure. (Conversion), and transform to the skeleton state (posture) at the time. This is performed based on the conversion relationship between the local coordinate system defined for each segment and the world (whole) coordinate system, and the conversion relationship between the local coordinate systems. In the case of the light source (camera), the light source (camera) is moved to the position at the time described in the time-series motion data and changed to the light source (camera) parameter at the time. The data obtained above is temporarily stored in the storage device 5.
To be kept.

I do. This process is performed in the same manner as the process 9 described in the first embodiment. In the process 54, the shading method described in the animation data
Rendering is performed using the arrangement data, light source data, and camera data of the environment shape once held in the storage device 5 and the shape data of the bound object or the surface shape data of the generated object to generate an image at the time. I do. This processing is performed in the same manner as processing 10 shown in the first embodiment. In the process 55, the image data stored in the storage device 5 is displayed on the display device in the same manner as that usually performed by computer graphics. Processing 5
In step 6, it is determined whether or not the end command has been issued. This processing is performed in the same manner as processing 12 described in the first embodiment. If the end command has not been issued, steps 48 to 56 are repeated. Embodiment 4 FIG.

For basic actions, action rules, and time-series basic motion data, adjust the combination of basic actions and transitions, adjust the connection time, and make sure that the movement is properly changed according to the environmental condition, or perform the desired movement. Check if it is correct and correct it as needed. At the time of these confirmations, confirmation of the attribute data light source data, camera parameters, shading method, environment setting, and environment management control method is also performed at the same time.

The process 63 is the process 3 of the first embodiment.
Perform in the same manner as described above. Processing 64 and processing 65 are performed in the same manner as processing 4 and processing 5 described in the first embodiment. The process 66 is performed in the same manner as the process 6 described in the first embodiment. The processing from the processing 67 to the processing 78 is for generating a computer graphics / animation image in the receiving computer 4. The description is given below. The process 67 is the process 7 of the first embodiment described above.
Perform in the same manner as described above.

In a process 68, processes relating to detection of occurrence of an event and state transition of a basic action are performed. This is performed in the same manner as in the third embodiment. However, when the basic behavior is changed, the time-series basic motion of the changed basic behavior is stored in the area in the storage device 5 where the current state for each skeletal structure is written, as described in the third embodiment. The name or identifier (address) indicating the location in the data storage device 5 and the time of the current state are stored. In the case of a transition, an identifier indicating the transition and a name or identifier (address) indicating the location in the storage device 5 of the time-series data corresponding to the connection operation are stored. The identifier during the transition is written immediately after the occurrence of the event (the relevant time).

However, when transitioning to a basic action of a type that unconditionally shifts to another basic action, an identifier indicating that the transition is in progress (giving an identifier different from the one described above), or A name or identifier (address) indicating the location in the storage device 5 of the series data, the basic action to be passed (in the case of a change, the location in the storage device 5 of the time-series basic motion data corresponding to the changed basic action). (Name or identifier) and the name or identifier of the post-passing basic action.

In the processing 69, it is determined whether the skeleton structure (light source, camera) to be processed is within the basic action period or the connection time at the time. This judgment is
This is performed by looking at the current state provided for each of the skeletal structures described above. Those that are not in a state transition are determined to be within the period of the held basic action. In process 70, process 6
If the current state is the last time of the basic action (time-series basic motion data) in each skeletal structure when it is determined that the basic action period is within the basic action period, the environmental management method and the action of the skeletal structure are performed. From the description of the rule, a process of confirming whether or not the environment meets one of the state conditions of the environment is performed. In this confirmation processing, if some condition is satisfied, the basic action (corresponding time-series basic motion data) is changed. Hereinafter, a specific method of changing the basic behavior will be described.

The change of the basic action includes extension and compression of the action related to time, change of the waypoint of the original action, synthesis of two actions, and change of the partial structure of the skeletal structure by exchanging the action. Regarding expansion and compression with respect to time, FIG.
Explanation will be made based on (b). FIG. 15A shows elongation with respect to time. For the time-series basic motion data corresponding to the original basic action, the number of times (the number of frames) is F,
Assuming that the operation time is T, the number of times is changed to F ′> F to extend the time. First, an interpolation curve is generated from the original time-series basic motion data (generated by polynomial interpolation or the like), the value of the interpolation curve for each time T / F 'is obtained, and new time-series data is generated. Create time-series basic motion data with time expansion. FIG. 15B shows the compression with respect to time. In this case, the same operation as expansion may be performed under the condition that F '<F. Change parameters include:
Give the scale amount for F 'or F. When these parameters are constants, they are fixed changes, but when these change parameters are variables, it is sufficient to give values according to the situation.

FIG. 15C shows a case where the waypoint of the original motion is changed. The time (tp, tq in FIG. 15 (c)) serving as the key of the waypoint to be changed, the change value, and the change time including the time are given, and the interpolation curve is obtained by using the data before and after the time and the data of the key time. Is generated, and the value of the time other than the key in the change time is obtained from the interpolation curve, and the changed time-series basic motion data is generated. The change parameters in this case are a key time sequence, a corresponding change value sequence, and a change time. As in the case of the above-mentioned expansion and compression related to time, when these parameters are given as constants, they are fixed changes. However, if they are defined as variables and given their values each time they are changed, The operation can be changed on the spot.

FIG. 15D shows the combination of two motions by the connection weighting function in the process 30 shown in the second embodiment. First, the number of operation times (the number of frames) of both motions is matched by using the above-described expansion and compression with respect to time. Next, synthesis is performed using the connection weighting function used in the operation connection shown in the processing 30 shown in the second embodiment. In other words, the two movements with the adjusted time
(t), B (t), and when the connection weighting function is φ (t), a composite operation is generated by A (t) φ (t) + B (t) (1-φ (t)). . This is a movement that gradually changes from A (t) to B (t). If φ (t) = (constant between 0 and 1) in the above equation, steady combination is obtained. The change parameters are the number of times F, the name or identifier of the basic action to be combined, and an identifier indicating the combination method (connection weighting, steady combination) (the combination method is symbolized in advance). If the number of times F, the identifier of the basic action to be combined (in this case, the processing is difficult with the name), and the identifier of the combining method are given as variables, it is possible to generate a combining action according to the situation.

As for the exchange of the motion with respect to the partial structure of the skeleton structure, the number of times of the operation after the exchange is matched with the number of times of the operation before the exchange by using the above-described expansion and compression with respect to time.
What is necessary is just to exchange operation | movement of a partial structure. In this case, it is the name or identifier of the basic operation to be exchanged for the name or identifier of the substructure. If these parameters are given as variables (however, identifiers), the operation can be changed according to the situation.

The process 71 reads the vector amount (state data) of the skeleton structure (light source, camera) at the time from the changed time-series basic motion data or the original time-series basic motion data. In the reading method, a vector amount at a time obtained by adding 1 to the current time secured for each basic action stored in the storage device 5 is read from the corresponding time-series basic motion data. After reading, update the current time. If the current time exceeds the time of the maximum value of the time-series basic motion data, it is set to 0 (the maximum value of the time + 1 remainder). This enables a toggle operation. In the case of a skeletal structure, it is moved (converted) to the position at the time according to the read vector amount,
The skeleton state (posture) at the time is transformed.

This is performed based on the conversion relationship between the local coordinate system defined for each segment and the world (whole) coordinate system, and the conversion relationship between the local coordinate systems. In the case of the light source (camera), the light source (camera) is moved to the position at the time described in the time-series motion data and changed to the light source (camera) parameter at the time. The data obtained above is temporarily stored in the storage device 5.

In the process 72, if it is determined in the process 69 that it is within the connection period (ie, during the transition), and immediately after the occurrence of the event (the current time), the state condition of the environment with respect to the basic behavior at that time is determined. I do. For basic actions that unconditionally move to another basic action, which are in transition immediately after the event occurs, the environmental state conditions for the basic action to pass and the environmental conditions for the basic action after passing The condition is determined. In the process 73, if a transition is being made and immediately after the occurrence of the event, a connection operation is generated based on the determination result of the process 72, and the name or identifier (address), the connection time, and the generated time-series connection operation data are stored. It is stored in the device 5. Otherwise, no connection action needs to be generated.

[0149] The connection operation is generated when the result of determination of the state condition of the environment in the process 72 does not need to change the subsequent basic action (it does not apply to any of the state conditions of the environment). This is the same as the processing 51 shown in the third embodiment.
When it is determined in the process 72 that the post-basic action needs to be changed as a result of the determination of the state condition of the environment, the post-basic motion data is changed, and then the post-basic motion data is changed. A connection operation is generated in the same manner as in the process 51 shown in 3 and the connection operation generated based on the change method and the connection operation change parameter indicated in the action rule is changed by the above-described operation change method.

In particular, in the case of the type of unconditionally moving to another basic action, the same processing as described above is performed for both the basic action after passing and the basic action after passing, and two connection actions are generated. The generated connection operation stores the name or identifier, the connection time, and the generated time-series connection operation data in the storage device 5. If the basic action after passing has been changed, the changed time-series basic motion data is used for the first time.

In the process 74, the skeleton structure is extracted from the connection operation (the modified time-series basic motion data or the original time-series basic motion data corresponding to the basic action to be passed in the case of the passing operation) generated in the process 73. In the case of (1), it is moved (converted) to the position at the time, and transformed into the skeleton state (posture) at the time. This is performed based on the conversion relationship between the local coordinate system defined for each segment described above and the world (whole) coordinate system, and the conversion relationship between the local coordinate systems. In the case of the light source (camera), the light source (camera) is moved to the position at the time described in the time-series motion data and changed to the light source (camera) parameter at the time. The data obtained above is temporarily stored in the storage device 5.

In the processing 75, the corresponding object shape is bound or the surface shape of the object is generated in accordance with the position and the skeletal state (posture) of the skeletal structure at the time stored in the storage device 5. I do. This process is performed in the same manner as the process 9 described in the first embodiment. In the process 76, by the shading method described in the animation data,
Using the layout data of the environmental shape, the light source data, the camera data, the shape data of the bound object, or the surface shape data of the generated object once, the rendering is performed to generate an image at the time, which is temporarily stored in the storage device 5. This processing is performed in the same manner as processing 10 described in the first embodiment. In the process 77, the image data stored in the storage device 5 is displayed on the display device in the same manner as that usually performed by computer graphics. In step 78, it is determined whether or not the end command has been issued. This processing is performed in the same manner as processing 12 described in the first embodiment of the present invention. If the end command has not been issued, the processes 68 to 78 are repeated.
