Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD This invention relates to improvements in computer technology for creating animations.

[0002]

In the present invention, two-dimensional images, three-dimensional images,
Alternatively, various objects such as an observation camera for displaying a three-dimensional image can be used as the object to be animated, and the case where the three-dimensional image is used as the object will be described below as an example.

Generally, a technique for creating an animation of a three-dimensional image (hereinafter, three-dimensional object) is known. This technique can be used in various applications, but is used, for example, when creating an electronic catalog of construction machines that are goods or rental items. That is, in the electronic catalog of the construction machine, in order to make it easy to understand the structure and the state change of the construction machine (for example, the movement of each main part such as the boom, the arm, the bucket, the way of turning, etc.), It is desirable to display a three-dimensional object (hereinafter, construction machine three-dimensional object) as an animation rather than simply displaying a still image. In order to meet such a demand, when creating an electronic catalog of construction machines, animation of construction machine three-dimensional objects is performed.

[0004]

A construction machine is usually composed of a plurality of parts, and a construction machine three-dimensional object is an aggregate of three-dimensional objects of a plurality of parts (hereinafter, part three-dimensional objects).

Conventionally, in order to create an animation of a construction machine three-dimensional object, state change attributes such as a starting point, an end point, a moving direction, and a moving time length must be set for each three-dimensional object of each part. . This is true even if the parts are of the same type and change state as well. For example, if you want to create an animation that shows a change in the state where six screws that hold a part are removed, even if you want to move the six screws the same, For each, the state change attribute including the same movement distance and the like must be set separately. When the moving distance of each screw is different, it is necessary to create an animation while memorizing what moving distance is set for which screw. Therefore, a lot of labor and time are required to complete the animation of the construction machine three-dimensional object. This is the number of construction machine 3D objects themselves,
The more the number of the component three-dimensional objects constituting each construction machine three-dimensional object is, the more it is.

Further, conventionally, in order to create an animation of a construction machine three-dimensional object, the state change attribute must be set for each part three-dimensional object as described above, so the basic construction of the construction machine is You may be required to know the characteristics and characteristics. Specifically, for example, it may not be possible to create an appropriate animation without knowing what kind of parts and how many parts exist at which position. For this reason, not everyone can easily create an animation of a construction machine three-dimensional object.

In the electronic catalog described above, an animation in which a construction machine which is a finished product is disassembled (hereinafter, disassembly animation) and an animation in which the disassembled construction machine is assembled to be a finished product (hereinafter, assembly) It may be desired to have both. Conventionally, it is necessary to create the disassembly animation and the assembly animation separately. This is a hassle for animation creators.

The above-mentioned problems are considered to exist even when an animation of an object other than the construction machine three-dimensional object is created.

Therefore, an object of the present invention is to make it possible to create an animation more easily than before.

[0026]

1 shows the configuration of a computer system in which an animation creating program according to an embodiment of the present invention is installed.

The computer system 1 shown in FIG.
It can be used as a dedicated local machine for creating the animation of the finished product 3D object described later, or a server machine that distributes the created 3D object animation of the construction machine via a communication network such as the Internet. Can also be used as In the computer system 1, the method of managing the data of the three-dimensional object (three-dimensional model), the delivery method, and the like are described in, for example, the applicant's prior application (Japanese Patent Application No. 2001-13257
4 or Japanese Patent Application No. 2001-136951, which is unpublished at the time of filing of the present application) may be used as described in the description and drawings.

The computer system 1 includes an animation database (hereinafter, animation DB) 4
0 and an animation creating program 11 are provided.

The animation DB 40 is created by the animation creating program 11 which can be associated with one or more objects consisting of a plurality of parts three-dimensional objects (hereinafter, finished product three-dimensional objects) and parts three-dimensional objects. Animation data and the like can be stored (in FIG. 1, for convenience of explanation, one piece of construction machine three-dimensional object 13 is stored in the animation DB 40, and the construction machine three-dimensional object 13 has four pieces. It shall consist of three parts 3D objects 3, 4, 7, and 8).

Here, each part three-dimensional object 3,
4, 7 and 8 are, for example, CAD (Computer-Aided Desig).
n) Three-dimensional image data created by the system. Each part three-dimensional object 3, 4, 7, 8 can be arbitrarily selected when setting a part object pack described later. Each part 3D object 3,
Specifically, 4, 7, and 8 are configured as follows, for example.

That is, each part three-dimensional object 3,
Reference numerals 4, 7, and 8 are composed of basic display information that describes the shape of the part, state information that describes the display method, arrangement position, etc. of the part.

Examples of the basic display information include three-dimensional shape data described as a surface model based on polygon data. The three-dimensional shape data is composed of shape data for each part or part assembly. The shape of the component in the virtual three-dimensional space is uniquely determined by the three-dimensional shape data, but the arrangement position of the component and the like are determined by other data described later.

The state information includes, for example, texture data and arrangement data. The texture data is data that is attached to the surface of the three-dimensional component, and is composed of a plurality of types of image data according to the material, texture, color, etc. of the component. Also, the transparency can be set, and the component can be expressed as semi-transparent or transparent. The placement data describes the placement position of each component in the three-dimensional virtual space. At least one piece of the arrangement data is associated with one part three-dimensional object 3 or 7, but when there are a plurality of identical parts, the three-dimensional objects 3, 4, 7, or 8 of the same part are allocated. Are associated with each other (thus, the three-dimensional object of the same part is displayed at each predetermined position of one construction machine).

The animation creating program 11 responds to a request from a user who operates an input device (for example, a pointing device such as a mouse) (not shown) provided in the computer system 1 to generate animation data by the method described below. create.

That is, the animation creating program 11 receives from the user the selection of a desired part three-dimensional object among the plurality of part three-dimensional objects 3, 4, 7, and 8 constituting the finished product three-dimensional object 13. For example, when the parts three-dimensional objects 3 and 4 are selected, the animation creating program 11 groups the parts three-dimensional objects 3 and 4, in other words, the parts three-dimensional objects 3 and 4 into one part object. Set as pack 5. Then, the animation creating program 11 inputs a common state change attribute (for example, a movement start point, a movement end point, a movement direction, a movement time length, a turning direction, a rotation axis or a rotation angle) to the set component object pack 5. Accept from user. When the common state change attribute is input, the animation creating program 11 applies the input common state change attribute to each of the part three-dimensional objects 3 and 4 in the part object pack 5 to obtain each part three-dimensional object. The timelines 3 and 4 (how the state changes with time) are determined. Then, the animation creating program 11 creates animation data (hereinafter referred to as single animation data) 17 including each determined timeline, and uses it to create the individual part three-dimensional objects 3, 3 in the part object pack 5. It is stored in the animation DB 40 in association with. here,
Unlike "composite animation data" described later, "single animation data" is animation data that does not include any other animation data.

The series of processing explained in the upper part is performed by another part three-dimensional object, for example, the part three-dimensional object 7,
The same applies when 8 is selected. That is, when the component three-dimensional objects 7 and 8 are selected, the animation creating program 11 sets them as different component object packs 9 and accepts the input of the common state change attribute for the component object packs 9 from the user. When the common state change attribute is input, the animation creating program 11 applies the common state change attribute to each of the part three-dimensional objects 7 and 8 in another part object pack 9 to obtain each part three-dimensional object 7 , 8 timelines are determined, and single animation data including each determined timeline (for example,
Create decomposition animation data or assembly animation data) 19 described later. Then, the animation creation program 11 uses the single animation data 1
9 is associated with individual part three-dimensional objects 7 and 8 in another part object pack 9 and the animation D
Store in B40. By repeating the series of processes described above, the number of single animation data registered in the animation DB 40 increases. Further, the content of each timeline in the registered single animation data can be modified to the content desired by the user.

When there are a plurality of single animation data in the animation DB 40, the animation creating program 11 can accept the selection of two or more single animation data from the plurality of single animation data from the user. . Here, for example, when two single animation data 17 and 19 are selected, the animation creation program 11 uses two or more timelines included in each selected single animation data 17 and 19. Determine multiple new timelines. Then, the animation creating program 11 creates new animation data including the plurality of new timelines (in other words, animation data obtained by combining two single animation data 17 and 19, hereinafter referred to as composite animation data) 2
1 is created and stored in the animation DB 40. By repeating such a series of processing,
The number of composite animation data registered in the animation DB 40 also increases.

When there are a plurality of composite animation data in the animation DB 40, the animation creating program 11 can accept selection of two or more desired composite animation data, and when two or more composite animation data are selected. Is the selected 2
Create new composite animation data based on the above composite animation data. (In addition to composite animation data, if one or more single animation data is selected, the new composite animation data is also used. Create animation data). In this way, by repeatedly synthesizing the animation data, in the animation DB 40,
A plurality of animation data are registered hierarchically. That is, in the hierarchy of animation data, the single animation data exists at the bottom, and the composite animation generated based on the single animation data and another animation data at the upper part of the single animation. Animation data exists, and further composite animation data created based on the composite animation data and animation data different from the composite animation data exists above the composite animation data.

The animation creating program 11 includes an animation in which a construction machine which is a finished product (that is, in an assembled state) is disassembled (that is, a disassembly animation), and a construction machine in a disassembled state is assembled and is a completed product. It is possible to accept from the user a selection as to which animation to create from among the following animations (that is, assembly animations), and create data for the selected type of animation. When the animation creating program 11 creates the disassembly animation data in response to the user's request, the animation creating program 11 changes the state opposite to the state change of the construction machine due to the disassembly animation (that is, the construction machine in the disassembled state is assembled. Data for assembly animation is automatically created. On the other hand, if the animation creating program 11 creates the assembly animation data in response to the user's request, the animation creating program 11 changes the state opposite to the state change of the construction machine due to the created assembly animation (that is, it is disassembled before being assembled). Will be in a state of
Automatically create disassembly animation data.

The operation of the animation creating program 11 when creating and editing an animation is basically the same in both disassembly animation and assembly animation. Hereinafter, the process executed by the animation creating program 11 will be described in more detail by taking the case of creating and editing the disassembly animation as an example. For the above reason, however, the animation when creating and editing the assembly animation is described below. It should be possible to easily understand the processing contents performed by the creation program 11.

When the disassembled animation is created, the following animation files are used, for example.

2 to 4 show an example of an animation file used when creating a disassembly animation. One animation file is a combination of FIGS. 2 to 4 according to the drawings.

In the animation file, a static scene description as shown in FIG. 2, an animation description as shown in FIG. 3 (simply referred to as “animation description” in FIG. 3), and as shown in FIG. There is a description of the object group (these descriptions are XML (extensible mar
kup language), but not necessarily XML).

The static scene description shown in FIG. 2 shows the state before the animation, and is described in advance or when the disassembled animation is created. The static scene description includes global parameter setting, camera description, and object arrangement description.

The global parameter setting means parameter setting for the entire finished product three-dimensional object.

The description of the camera represents the turning information of the observation camera for displaying the completed three-dimensional object, the gazing point (that is, the coordinates (position) in the virtual space which is the line of sight of the observation camera), and the like. It is a thing.

The description of the arrangement of the objects means the scale (magnification) and the position (coordinates in the virtual space) of each of the three-dimensional objects constituting the finished product three-dimensional object.
It represents.

The animation description shown in FIG. 3 shows the contents of the animation of the finished product three-dimensional object. Specifically, the description of the disassembled animation data created in response to the user's request (see FIG. 3). It simply includes "disassembly animation") and a description of assembly animation data automatically created based on the disassembly animation data (simply "assembly animation" in FIG. 3).

The disassembled animation data includes, for example,
Animation name 199 and animation type 200
Data items such as a movement axis 201, an animation target 203, a reproduction time 202, an object name 204, a timeline 205, and a state change item 206 are included.

The animation name 199 is an identification name (“Pack_001” in the illustrated example) of the disassembly animation.

The animation type 200 indicates whether it is a disassembly animation or an assembly animation in this embodiment. In the illustrated example, “Normal” is described in the case of the disassembly animation, and “Reverse” is described in the case of the assembly animation, but it is not limited to this. Further, as will be described later, the principle of the present invention is applied not only to disassembly animation and assembly animation, but also to various types of animation such as transparency of parts, size change, color change, and movement of observation camera. However, in that case, the word described as the animation type 200 becomes another word.

The movement axis 201 indicates the direction in which the finished product three-dimensional object is disassembled. Since the moving axis 201 is “Z” in the illustrated example, the finished product three-dimensional object is disassembled in the Z-axis direction (specifically, the three-dimensional parts of the parts constituting the finished product three-dimensional object are arranged. The original object moves in the positive or negative Z direction).

The animation target 203 is a part object pack that is an animation target. In the illustrated example, as the animation target 203,
"Pack_001" is described.

The reproduction time 202 is the reproduction end time (in other words, the reproduction time length) when the reproduction start time is "0 second". In this embodiment, when the reproduction time “3 seconds” is input from the user as one of the state change attributes, the sampling created by the animation creating program 11 from 0 to 3 seconds at equal intervals. Value (hereinafter, playback time sampling value) "0.00",
“1.50” and “3.00” are described as the reproduction time 202 (note that the reproduction time sampling values can be extracted more finely or roughly, and need not be evenly spaced).

The object name 204 is an identification name of a part three-dimensional object (hereinafter, selected part object) selected by the user as a component of a part object pack to be animated. In the illustrated example, it means “01_bolt_upper”, “02_washer_upper”, etc. (In FIG. 3, only two object names 204 are described, but actually, the same number as the number of selected component objects is described. Be done).

The timeline 205 is described according to the selected part object. The timeline 205 represents a change in the state of the selected part object according to the reproduction time 202. In this embodiment, the timeline 2
Reference numeral 05 denotes the position (coordinates in the virtual space) of the selected part object corresponding to each reproduction time sampling value. For example, playback time 202 and object name 204
According to the timeline 205 of the selected component object whose “01_bolt_upper” is “01_bolt_upper”, the selected component object has coordinates “0.00,
Located at 0.00,65.00 ”and by moving from there
After 1.5 seconds, it will be located at coordinates "0.00,0.00,82.86", and by moving from there, 3 seconds later, it will be at coordinates "0.00, 0.
You can see that it stops at 00,100.71 ”.
In the disassembly animation, the coordinates at the end of movement of each selected part object are the placement of each selected part object,
The coordinates are set based on the starting point and the ending point input by the user, and do not necessarily match the starting point and the ending point. In the disassembly animation, the coordinates at the time of starting the movement of each selected part object are typically the positions arranged in advance.

The status change item 206 represents what kind of status change is performed. In the illustrated example, it represents that the position of the selected part object changes (the start point, the end point, the reproduction time, etc. input by the user for the state change item 206 are state change attributes).

The data items 199 to 206 are provided when the disassembled animation is created, and are in a blank state (that is, a blank state) until an animation registration command is received from the user. Each data item 199-20
After the predetermined information such as the common state change attribute and the animation name is input by the user, the content of 6 is described based on the various input information.

The assembly animation data is the data item 19 included in the above-mentioned disassembly animation data.
It was created automatically based on 9-205,
It includes the same data items as the data items 199 to 205 described above. In the assembly animation data, the animation type 200 is described as “Reverse” as already described. Also, the contents of the timeline 205 of each selected part object are opposite to those of the disassembly animation, that is, the intermediate values among the plurality of reproduction time sampling values are replaced. Thus, in the assembly animation, for example, the selected part object whose object name 204 is “01_bolt_upper” is located at the coordinates “0.00,0.00,100.71” at the end of the disassembly animation at the start of movement, and 1.5 seconds later. Is the same as in the disassembly animation, “0.00,0.00,
It is located at 82.86 "and after 3 seconds it is located at the coordinates" 0.00, 0.00, 65.00 "at the start of the disassembly animation.

Now, the description of the object group shown in FIG. 4 means a part object pack (that is, a group of selected part objects) which is an object of animation.
It represents information about the selected part object included in the. In the illustrated example, the identification name of the part object pack to be animated (for example, "Pack
_001 ") and the object name of each selected part object (" 01_bolt_upper "," 02_washer_upper ", etc.).

The respective descriptions as described above do not necessarily have to be in the same file as in the present embodiment. For example, the description shown in FIG. 2 is in one file and the description shown in FIG. 3 is in another file.
The description shown in may be in another file.

FIG. 5 shows the flow when a disassembly animation is created. 6 to 20 show examples of screens (graphical user interface) displayed on the computer system 1 when the disassembly animation is created. Hereinafter, FIG. 6 to FIG.
The flow when the disassembly animation is created will be described by appropriately using.

As shown in FIG. 5, when the animation creating program 11 receives a request for creating an animation from the user (step S0), the animation creating program 11 responds to the screen as shown in FIG. 6 (hereinafter referred to as the animation creating screen). )
Is displayed on the display screen of the computer system 1.

On the animation creation screen, a finished product three-dimensional object (that is, a three-dimensional image of the finished product),
The name "tank2" of the finished product three-dimensional object and the names of each of the plurality of component three-dimensional objects included in the finished product three-dimensional object ("01_bolt_upper", "0
2_washer_upper ”etc.) is displayed. The finished product three-dimensional object is displayed with the line of sight of the observation camera according to the description of the camera in the animation file (see FIG. 2). In addition, the names of each of the plurality of three-dimensional object parts are arranged in a predetermined order according to the description of the arrangement of the objects in the animation file (see FIG. 2) (for example, they are arranged at a high position in the virtual space). The more parts that are displayed on the top).

Although not shown, a plurality of independent sub-component three-dimensional objects are collectively defined as one group in the plurality of component three-dimensional objects displayed on the animation creating screen. (In other words, among a plurality of part three-dimensional objects, there is a part three-dimensional object in which two or more sub-part three-dimensional objects have a hierarchical structure). For example, the part three-dimensional object “01_bolt_upper” is a group of six sub-part three-dimensional objects that represent one bolt, although not shown. As a result, one part 3D object "01_b
If "olt_upper" is selected, the sub-part three-dimensional object of 6 bolts is selected. That is, the user
Unlike in the past, animation can be created if the structure of the finished product to be animated is known to some extent.

In the same manner as described above, the animation creating program 11 groups two or more parts 3D objects among a plurality of parts 3D objects displayed on the animation creating screen in response to a user's request. Can also be defined as a single 3D object.

In the state shown in FIG. 6, when the user performs a predetermined operation, the animation creating program 11 pops up a "pack edit" box on the animation creating screen, as shown in FIG. To do. In the "Edit Pack" box, click "Pack List".
There is a display column and a "member object" display column,
Both are blank at this point.

In this state, the animation creating program 11 displays the "new pack" on the "pack edit" box.
When the button is pressed by the mouse or the like, a "pack new creation" box is popped up on the "pack edit" box as shown in FIG. In the "Create new pack" box, a desired name can be entered for the part object pack to be an animation target.

The animation creating program 11
When the user-requested part object pack name (for example, "Pack_001") is entered in the "Create new pack" box and the "OK" button is clicked, the "Create new pack" box is closed and the entered part object pack name is entered. Is registered in the “pack list” display field of the “pack edit” box.

After this, the animation creation program 1
In response to the user's operation, as shown in FIG. 10 and FIG. 11, 1 indicates the user-desired part three-dimensional object among a plurality of part three-dimensional objects in the “pack edit” box in the order desired by the user. Register in the "Member object" display field. Animation creation program 11
Registers the object name of the part 3D object selected earlier in the upper part of the "member object" display field (hereinafter, the order of the part 3D objects listed in the "member object" display field). Is called the "object registration order").

In FIG. 11, when the "register" button in the "pack edit" box is pressed, the animation creating program 11 groups two or more three-dimensional objects registered in the "member object" display field into one group. As one part object pack, as shown in FIG. 12, the "pack edit" box is closed, and the part object pack is registered with the part object pack name previously input.

The series of operations up to now may of course be performed in advance when the disassembly animation is created.

Now, the animation creating program 11
As shown in FIG. 13, when the name “Pack_001” of the part object pack that is the animation target is selected, the first menu screen is displayed. When "Disassemble / assemble animation creation" is selected on the first menu screen, the animation creation program 11 causes the animation file to display each part three-dimensional object (hereinafter, element part) in the selected part object pack. Object) timeline. Specifically, for each part three-dimensional object, the data item 199 described above is prepared.
To 205 (however, the contents of predetermined data items are not filled) are prepared (S1 in FIG. 5). In addition, the animation creation program 11 is, as shown in FIG.
"Disassembly / assembly animation creation" on the animation creation screen
Display the box. In the "Disassembly / assembly animation creation" box, a state change attribute common to each element object can be input. In particular,
The “Disassemble / assemble animation creation” box has a desired animation name (described as “animation name” in FIG. 14), a starting point (ie, coordinates of one moving end), and an ending point (ie,
Make it possible to input the coordinate of the other moving end), the moving axis (that is, the axis along the direction in which the 3D object of each part moves by the exploded animation), and the playback time (that is, the playback time of the animation) Has become.

The animation creating program 11 is
When an animation name is input on the “Disassemble / assemble animation creation” box, the input animation name is described in the animation file (YES in S2 of FIG. 5, S3).

Also, the animation creating program 11
As shown in FIGS. 15 and 16, when a moving axis (denoted as “disassembly axis” in FIG. 5) is input in the “Disassembly / assembly animation creation” box, the input moving axis is animated. Described in the file, and accordingly, the movement axis is applied to each element part object (YE in S4 of FIG. 5).
S, S5).

Also, the animation creating program 11
When the playback time is entered in the "Disassemble and assemble animation creation" box, the specified multiple playback time sampling values are described in the animation file based on the entered playback time. It is applied to each element part object (YES in S6 of FIG. 5, S7).

Also, the animation creating program 11
When a starting point is input in the "Disassemble / assemble animation creation" box, the input starting point is described in the animation file, and the starting point is applied to each element part object (YES in S8 of FIG. 5, S9 ). Here, as shown in FIG. 17, when the starting point and the ending point have different values, the animation creating program 11 and the starting point and ending point at that time and the object registration order of each element part object (that is, the user The position of each element part object is moved to the position at the end of the disassembly animation on the animation creation screen, based on the order selected and registered in. In other words, the animation creating program 11 makes the moving distance of each element part object determined by the start point and the end point different based on the object registration order of each element part object. As a result, even if a common start point and end point are applied to each element part object, the following problems occur: At the end of the animation, the element part objects overlap and the element part objects cannot be identified. It is possible to avoid the occurrence of problems such as dead ends.

The animation creating program 11 is
In the "Disassembly / assembly animation creation" box, for example,
When an end point having a larger value than that in FIG. 17 is input, as shown in FIG. 18, the display position of each element object is changed by the same method as described above (YES in S8 of FIG. 5). , S9). In other words, the animation creating program 11 allocates the position of each element part object at the end of the animation within the range of the current start point and end point based on the object registration order of each element part object, The display position of each element object is changed based on the position.

The animation creating program 11 determines an individual timeline of each element part object based on each state change attribute input as described above, and describes it in the animation file.

The animation creating program 11
When the "Test" button on the "Disassemble / assemble animation creation" box is clicked, as shown in Fig. 19, based on the animation data currently described in the animation file, the completed product will be displayed on the animation creation screen. The decomposition animation of the three-dimensional object is reproduced (YES in S10 of FIG. 5, S11). Specifically, the animation creating program 11 reproduces the animation of each element part object based on the timeline of each element part object.

The animation creating program 11
When the "Register" button on the "Disassembly / assembly animation creation" box is clicked, the "Disassembly / assembly animation creation" box is closed as shown in Fig. 20, and the individual just before the "Registration" button is pressed. Register the disassembled animation data including the timeline of (see Fig. 5).
YES in S12, S13). At the same time, the animation creating program 11 displays the animation name of the registered disassembled animation data in the animation window at the lower left of the animation creating screen, as shown in FIG.

After this processing, the animation creating program 11 automatically creates an assembly animation based on the timeline of each element part object in the registered disassembly animation data. Then, the animation creating program 11 registers the data of the assembly animation in the animation file.

On the other hand, the animation creating program 11
Deletes the individual timeline immediately before the "Register" button is pressed from the animation file when the "Cancel" button on the "Disassemble / assemble animation creation" box is pressed (YES in S14 of FIG. 5). , S15).

The above is the flow when the disassembly animation is created. The above contents can also be applied to creating a rotation animation, for example. That is, the animation creating program 11 is input by selecting two or more three-dimensional object parts desired by the user and inputting a state change attribute such as a common rotation direction, rotation angle, or rotation axis desired by the user. It is possible to create a rotation animation in which the common state change attribute is applied to two or more three-dimensional object parts desired by the user. At this time, the animation creation program 11
Can adjust the rotation angle and the like of each of the two or more component three-dimensional objects based on a predetermined attribute (for example, the selected order) of the two or more component three-dimensional objects desired by the user.

Now, the flow when the data of the created disassembly animation is edited will be described.

FIG. 21 shows the flow when the created disassembly animation data is edited. 22 to 28
Shows an example of a screen (user interface) displayed on the computer system 1 when the disassembled animation data is edited. The flow when the created disassembled animation data is edited will be described below by basically using FIGS. 22 to 28 and appropriately using FIG. Hereinafter, the disassembly animation data to be edited is referred to as “target animation data”, and the part object pack related to the target animation data is “target pack”.
That is, the plurality of component three-dimensional objects included therein are referred to as “target component objects”.

As shown in FIG. 22, when the animation name desired by the user (“Pack_001” in the illustrated example) is selected in the animation window at the lower left of the animation creation screen, the animation creation program 11
Displays the second menu screen. As shown in FIG. 22, although only one animation name is displayed in the animation window even though there are two types of animation data, disassembly animation data and assembly animation data, in this embodiment, When one of the two types of animation data is edited, the other animation data is automatically edited based on the content of the edited animation data. Therefore, the animation creating program 11 according to this embodiment edits the disassembled animation data in the animation editing, and automatically edits the assembled animation data based on the edited disassembled animation data. Of course, the animation creating program 11 can be created so that one of the two types of user's desired animation data can be edited, or the disassembly animation data and the assembly animation data can be edited individually. You can also make it.

Now, when the user selects "Edit animation" on the second menu screen shown in FIG. 22, (see FIG. 21)
S20), the animation creation program 11 causes the user's cancel operation described later (YES in S35 of FIG. 21).
In preparation for S), a backup of the disassembly animation data having the selected animation name (that is, the disassembly animation data before editing) is created (S2 in FIG. 21).
1). And the animation creation program 11
A plurality of state change attributes (timeline, playback time, etc.) included in the target animation data are read (Fig. 2
In S22 of 1), the state change attribute of each read target part object is held as an internal variable, and as shown in FIG. 23, the “Disassembly / assembly animation edit” box is displayed. At this point, the “Disassembly / assembly animation edit” box is
The "position edit" tab is clicked, and the screen for "position edit" (hereinafter, position edit screen) is in a state of being displayed in front (S23 of FIG. 21, in other words, S24 of FIG. 21).
Then YES and S25 have been passed). The animation creating program 11 applies each timeline included in the read state change attribute to the position edit screen. From the position edit screen at this point, the disassembly position of each target part object is the starting point `` -50.
It can be seen that they are set at almost equal intervals in the range between "00" and the end point "50.00" (in other words, the movement distances of the plurality of target part objects in the disassembly animation are set in proportion to each other. Is understood).

In the position editing screen shown in FIG. 23, the animation creating program 11 changes the disassembly position of each target part object (that is, the position of the target part object at the end of the disassembly animation) as shown in FIG. If (YES in S27 of FIG. 21)
S) Based on the changed disassembly position, the current display position of each target part object on the animation creation screen is changed. At the same time, the animation creating program 11 changes each decomposition position included in the internal variable that it currently has to each decomposition position after the change (FIG. 21).
S28).

Also, the animation creating program 11
For the "time edit" when the "time edit" tab is clicked in the "disassembly / assembly animation edit" box shown in FIG. 23 as shown in FIG. 25 (NO in S24 of FIG. 21). The screen (hereinafter referred to as the time edit screen) is displayed in front (S26 in FIG. 21). The animation creating program 11 applies the reproduction time (in the illustrated example, the reproduction start time is 0 second and the reproduction end time is 3 seconds) included in the read state change attribute to the time edit screen. According to the time edit screen at this point, it is understood that a common reproduction time is applied to each target part object.

In the time edit screen shown in FIG. 25, the animation creating program 11 changes the reproduction time (that is, the reproduction start time point or the reproduction end time point) individually for a plurality of target part objects, as shown in FIG. If (YES in S27 of FIG. 21), the reproduction time of each target part object included in the internal variable currently held is changed to each reproduction time after the change (FIG. 21).
S28).

As shown in FIG. 27, when the "disassembly test" button is clicked in the "disassembly / assembly animation edit" box, the animation creating program 11 changes the disassembly position (that is, after editing) and reproduces it. A new timeline is determined for each target part object based on time, and according to the determined timeline,
The animation of the finished product three-dimensional object (specifically, a plurality of target part objects) is reproduced (FIG. 21).
S30).

After that, the animation creation program 1
1 indicates that the display tab (that is, the "position edit" tab or the "time edit" tab) is switched (S31 in FIG. 21).
YES), the screen corresponding to the tab after switching (that is, the position edit screen or the time edit screen) is displayed in front (FIG. 21).
S32).

Also, the animation creating program 11
When the “Register” button is clicked in the “Disassembly / assembly animation edit” box (YES in S33 of FIG. 21), the “Disassembly / assembly animation edit” box is closed as shown in FIG. A new disassembly animation data including a new timeline based on the disassembly position and the reproduction time of is registered in the animation file, and the backup created in the past is deleted (Fig. 21).
S34). Furthermore, animation creation program 11
Creates new assembly animation data based on the new (that is, edited) disassembly animation data and also registers it in the animation file.

Also, the animation creating program 11
When the “Cancel” button is clicked in the “Disassembly / assembly animation edit” box (S3 in FIG. 21)
If YES in step 5, the internal variables that are currently held are discarded, and the content of the disassembled animation data registered in the animation file is made the same as the content of the backup (S36 in FIG. 21).

The above is the flow when the created disassembly animation data is edited.

By the way, if a plurality of animation data are registered in the animation DB 40 (see FIG. 1), the animation creating program 11 composites two or more animation data desired by the user out of the plurality of animation data. New animation data (that is, composite animation data) can be created.

FIG. 29 shows the flow when composite animation data is created. 30 to 40 show examples of screens (user interfaces) displayed on the computer system 1 when composite animation data is created. Hereinafter, a flow when the composite animation data is created will be described by basically using FIGS. 30 to 40 and appropriately using FIG. 29.

As shown in FIG. 30, when the "composite animation creation" button is clicked on the animation creation screen (S40 in FIG. 29), animation creation program 1
As shown in FIG. 31, No. 1 pops up a "New creation of compound animation" box on the animation creation screen. In the "Create new complex animation" box, the user can enter the animation name for the complex animation data to be registered.

In the "Create new complex animation" box, the animation name desired by the user ("An" in the illustrated example is displayed.
im_001 ”) is input and the“ OK ”button is clicked, the animation creating program 11 displays a“ composite animation edit ”box as shown in FIG. 32 (S41 in FIG. 29). The "Composite Anime Editing" box
As described in detail later, registration of two or more animation data (hereinafter, element animation) that you want to be one element of composite animation data, correction of common state change attribute of parts object pack related to each element animation, etc. You can do it.

In the "Compound animation edit" box, as shown in FIG. 33, when a check mark is put in the "element addition" check box (that is, when an element animation addition is requested), the animation The creation program 11 receives the designation of the element animation.
The element animation can be specified by selecting a desired animation name from a plurality of animation names displayed in the animation window at the lower left of the animation creation screen. Each animation name displayed in the animation window is the name of the animation data including the disassembled animation data and the assembled animation data.

When the element animation desired by the user (for example, the animation data of the animation name "Pack_001") is selected from the animation window, the animation creating program 11, as shown in FIG.
Display the "Select Animation" dialog box and ask the user which of the disassembled animation data and the assembly animation data should be adopted as the element animation.

Here, for example, as shown in FIG.
When the "Disassemble" animation radio button is checked in the "Select Animation" dialog box (that is, when disassembling animation data is selected as the element animation), the animation creating program 11 disassembles the disassembling animation data with the animation name "Pack_001". As the element animation, as shown in FIG. 35, the animation name of the element animation and the reproduction time of the element animation (that is, the reproduction start time and the reproduction end time) are displayed in the “Composite animation edit” box ( Y in S42 of FIG.
ES, S43).

Also, the animation creating program 11
When another element animation desired by the user (for example, animation data of animation name “Pack_002”) is selected from the animation window, the “Select Animation” dialog box is displayed as shown in FIG. 36 in the same manner as above. indicate. Then, the animation creating program 11 selects the animation name “Pack_00 when the disassembly animation data is selected to be the element animation.
As the element animation, the decomposed animation data of "2" is displayed, and as shown in FIG. 37, the animation name of the element animation and the reproduction time of the element animation are additionally displayed in the "Compound animation edit" box.

By this flow, two element animations are contained in a tree shape in one composite animation data (composite animation data is incomplete at this point). On the "Composite Anime Edit" box, the playback time of each elemental animation, specifically, the playback start time and playback end time can be adjusted. This makes it possible to create a compound animation in which each element animation is played at the same time with the playback start time and playback end time of each element animation being the same, or the playback end time of one element animation being played back to the other element animation. By setting it as the start point, it is possible to create a composite animation in which element animations are played in stages.

The animation creating program 11
When the playback time of each elemental animation is adjusted on the "Compound animation edit" box, the composited animation data is generated by applying the adjusted playback time to each elemental animation (YES in S44 of FIG. 29, S45). ).

After that, the animation creation program 1
As shown in FIG. 39, when the “test” button is clicked on the “composite animation edit” box,
(YES in S46 of 9), the animation of the completed three-dimensional object in which each registered element animation is activated at a predetermined time point is reproduced based on the generated composite animation data (S47 in FIG. 29). Upon seeing the animation, the user again adjusts the playback time of each element animation, or performs detailed editing work on each element animation (for example, the moving axis of each three-dimensional object, the starting point,
Correction such as end point) may be made.

The animation creating program 11
When the “Register” button is clicked on the “Composite animation edit” box (YES in S48 of FIG. 29),
Close the "Composite Animation Edit" box as shown in
The created composite animation data is registered in a predetermined animation file, and the animation name "Anim_001" of the composite animation data is displayed in the animation window (S49 in FIG. 29). Here, as shown in FIG. 40, the animation creating program 11 can also display a mark that makes it possible to see at a glance whether it is composite animation data or single animation data. Although not shown, it is also possible to display a mark for the composite animation data so that the number of element animations can be seen at a glance.

The animation creating program 11
When the "Cancel" button is clicked on the "Composite Animation Edit" box (YES in S50 of FIG. 29),
The composite animation data created above is discarded (S
51).

The above is the flow when composite animation data is created. In the above description, the element animation is a single animation data, but of course, the composite animation data can be an element animation.

As described above, according to the above-described embodiment, the common state change attribute can be applied to a plurality of component three-dimensional objects. This makes it possible to reduce the amount of work required to create animation data, as compared with the conventional method of individually designating a three-dimensional part object and assigning a state change attribute. That is, animation data can be created with a small amount of labor and time.

Further, according to the above-described embodiment, when either one of the disassembled animation data and the assembled animation data is created, the other animation data is automatically created. As a result, it is possible to reduce the amount of work required to create the animation data, as compared with the conventional method in which the disassembly animation data and the assembly animation data are created separately. That is, animation data can be created with a small amount of labor and time.

Further, according to the above-described embodiment, one part three-dimensional object can define a plurality of sub-part three-dimensional objects. Accordingly, when one part three-dimensional object (for example, screw object) is selected, a plurality of sub-part three-dimensional objects (for example, six screw sub-objects) are selected. Therefore, it is possible to save the trouble of individually selecting the parts to be animated. Further, an animation can be created even if the basic knowledge (for example, the knowledge about the structure) of the finished product to be animated is small.

Further, according to the above-described embodiment, desired two or more element animations are selected from a plurality of animation data, and the reproduction time (that is, the reproduction start time point and the reproduction end time point) of each element animation is adjusted. You can create a composite animation in which two or more element animations are played individually. Thus, if there are a plurality of pieces of animation data that make a simple state change, it is possible to easily create animation data that makes a complicated state change simply by combining them. For example, if you want to create an animation that the screw rotates and comes off the finished product, select the animation data that the screw rotates and the animation data that the screw comes off,
It is only necessary to adjust the playback start time and the playback end time of each animation.

The preferred embodiment of the present invention has been described above, but this is merely an example for explaining the present invention, and the scope of the present invention is not limited to this embodiment. The present invention can be implemented in various other forms. For example, the present invention is not limited to disassembling and assembling state changes, and can be applied to creation of animations showing various types of state changes such as size change (for example, enlargement or reduction) of parts, transparency, or color change. You can Further, the present invention is not limited to the three-dimensional object itself, but can be applied to creation of an animation showing a state change of an observation camera or a two-dimensional image displaying the three-dimensional object. For example, when applied to the animation creation of the observation camera, when creating the animation of a plurality of observation cameras, the state change attribute (for example, the position (viewpoint) of the observation camera itself, the target position observed by the observation camera ( (Gaze point), turning direction, magnification when zooming in or out, etc.) does not need to be set for each observation camera, that is, the state change attribute can be set for a plurality of observation cameras at one time.
