Description

  The present invention relates to a three-dimensional content generation method, a program, and a client device.

  There is a technology to create 3D animations by moving objects such as characters on the time axis in a 3D (3D) virtual space or in a space where 3D virtual space and real space are fused. To do.

  A three-dimensional animation is generated in the form of a two-dimensional three-dimensional animation by projecting a model onto a two-dimensional space along the time axis. Alternatively, a three-dimensional virtual space is simulated for humans by projecting a three-dimensional virtual space into a two-dimensional space in correspondence with the left and right eyes and generating two two-dimensional three-dimensional animations. It can also be generated in the form of

  The model can be converted to 3D animation in near real time, and the operator can change the 3D animation seen from various angles and various positions of the model in real time by changing the position and settings of the pseudo camera. be able to. On the other hand, movies such as movies and television are displayed by switching a plurality of two-dimensional frames that have already been taken at predetermined time intervals and displaying them in a frame-by-frame manner. .

  Therefore, the three-dimensional animation that can change the viewing direction and the like in real time can make a human experience a more realistic virtual space compared to a moving image based on an existing frame.

  In addition, the three-dimensional animation can be changed by editing the components of the model.

  Conventionally, there is a technique in which a plug-in is subdivided to a momentum that is a behavior of a video expression function unit, and a video object is created by freely combining these plug-ins (see, for example, Patent Document 1). .

  Also, content creators who edit and generate content want to use the content editing server that accesses the content generation server from the content editing terminal and is registered in the content / material / template storage unit through the material / change data input unit. There is a technology for selecting a template, displaying the template on a content editing terminal, inputting a material (image, sound, moving image, text) according to the template, and generating content (for example, Patent Document 2).

  In addition to the character information that is the body of the message, the “message” includes motion identification information (motion ID) that uniquely identifies motion information that defines the motion of the avatar. An avatar is a kind of character image that represents a sender (user), and is created / selected in advance before execution of message processing, for example, and registered in an SNS server, for example. As a result, there is a technique in which an avatar that performs an appropriate operation corresponding to each user is associated (see, for example, Patent Document 3).

  However, in the past, emphasis was placed on creating 3D animations from multiple materials, and by using the already created 3D animation components, multiple created 3D animations were used. It was difficult to create new 3D animations by freely combining new 3D animations derived from.

  In this specification, a pose can be understood as a motion having a time length of zero. Therefore, both motion and pose are treated as motion.

  In this specification, character words are mainly used. Characters are mainly used for virtual persons or creatures. However, the embodiment does not exclude virtual objects such as general objects (for example, bicycles, automobiles, balls, etc.) other than virtual persons or living things. Therefore, it should be noted that virtual characters, objects, and the like used in this specification can be collectively referred to as virtual object words.

  In this specification, a skeleton model having bones is used as an example of a three-dimensional object. However, the embodiment is not limited to a specific three-dimensional object. That is, the embodiment described below may be applied to a three-dimensional object having no bone and a three-dimensional object using other than a bone.

  The three-dimensional model in this specification includes a plurality of components and is used as a word for generating a three-dimensional animation. The three-dimensional model will be described simply using model terms.

  FIG. 1 is a functional block diagram of the client device 100. The client device 100 is connected to the server device 120 via a network 130 such as the Internet. The client device 100 may be any computer that can send and receive data to and from the server device 120, such as a mobile terminal, a mobile phone, a laptop computer, a desktop computer, a pad, and a tablet.

  The client device 100 includes a download unit 102, a display unit 110, a modified model generating unit 104, and an upload unit 106. The display means 110 includes means 112 for displaying the relationship. Relationships include relationships that define ancestors and descendants of model modifications. Details of the relationship will be described later.

  There may be a plurality of client devices 100. A plurality of server devices 120 may also exist.

  The server device 120 can store a plurality of models. The stored model is provided to the client device 100 in response to a request from the client device 100. When the server apparatus 120 provides the model to the client apparatus 100, a charging process may be performed on the user of the client apparatus.

  An outline of the operation of the client device 100 will be described below.

  The download unit 102 can designate one or a plurality of models among a plurality of models stored in the server device 120. The specified model or models are downloaded from the server device 120 to the client device 100 by the download unit 102. The downloaded one or more models may be stored in a storage unit (not shown) that exists in the client device.

  The stored one or more models are converted into a three-dimensional animation by the display means 110 and displayed on a display or the like. As will be described later, the displayed three-dimensional animation can change the viewing angle and direction of a character or the like in the three-dimensional animation by arbitrarily changing the position of the virtual camera by the user.

  The means 112 for displaying the relationship included in the display means 110 is further modified based on the model (ancestor) that is the basis for modifying the model selected for display and the model selected for display. Information specifying a model (descendant) and the like can be displayed. Information specifying the oldest ancestor may be displayed on the screen. Here, the information to be identified includes a two-dimensional image of a characteristic snapshot of the three-dimensional animation, a name for identifying the model, information on an author who created the model, and the like.

  In the above-described embodiment, an example in which a model or the like is downloaded from the server device 120 to the client device 100 and converted into a three-dimensional animation in the client device 100 is shown. The embodiment is not limited to this, and all processing such as conversion to a three-dimensional animation may be performed by the server device 120 without downloading a model or the like from the server device 120 to the client device 100. Alternatively, all processes may be performed by a third device other than the server device 120 and the client device 100, and the converted three-dimensional animation may be distributed to the client device 100.

  Details of the descendants and ancestors of the above model will be described later with reference to FIG.

  The means 104 for generating a modified model replaces a part of a plurality of constituent elements of a predetermined model with each constituent element of one or more other models, thereby creating a new constituent element. A model consisting of a combination of Moreover, you may create the model which consists of a combination of a new component by adding each component of one or more other models to a predetermined model.

  The modified model is input to the display unit 110. The display unit 110 generates a modified three-dimensional animation from the modified model. The modified three-dimensional animation is displayed on the display.

  The means 104 for generating the modified model may output the modified model to the upload means 106.

  The upload unit 106 can transmit the modified model to the server device 120 via the network 130. The modified model is accumulated by the server device 120 so as to be provided to the client device 100.

  FIG. 2 is a flowchart illustrating a method according to an embodiment.

  In step 202, the client device downloads at least two models (and relationships).

  In step 206, the client device generates a modified model (and relationship).

  In step 208, the modified model (and relationship) is uploaded to the server device.

  In step 204, the downloaded relationship may be displayed.

  FIG. 3 is a diagram showing an example of a skeleton model (skeleton model) used when creating a three-dimensional animation.

  FIG. 3A shows an example of a specific skeleton model that defines a character. The skeleton model is connected by a bone 301, a bone 302, and the like. Each part constituting the skeleton model is called a node, and each node can have a parent-child relationship. The state of node rotation (bending, twisting) can be expressed by the direction of the child node with respect to the parent node. In order to express the direction of the node, a coordinate system is defined for each node (not shown). A line segment connecting the origins of nodes in a parent-child relationship, or the node itself is a bone.

  In such a skeleton model used for controlling the posture (pose, motion, etc.) of a human body model, an animal, a structure, etc., the position, rotation (bending, bending) of each bone and joint shown in FIG. (Twist) etc. must be controlled as intended. In the skeleton model shown in FIG. 3A, each bone is connected by a joint, and the movement of each bone affects the movement of the other bone. Conventionally, various methods for modeling a skeleton and controlling the skeleton model have been proposed.

  There has been proposed a method for easily controlling a pose or motion of a model by defining a pose or motion in advance for the model and applying the pose or motion to the model (for example, Japanese Patent Application Laid-Open No. 2013-2013). No. 1203953).

  FIG. 3B shows a character 310 in which a plurality of polygons representing the body surface are associated with a plurality of bones.

  By using the character 310, a motion can be given to the virtual three-dimensional character 310 to move the character 310 on the screen.

  FIG. 4 is a diagram illustrating an example of generating a three-dimensional animation from a model by setting a virtual camera 402. The character 404 is a character that exists in a virtual three-dimensional space. There may be a plurality of characters. A background 406 exists in a virtual three-dimensional space. An arrow 403 indicates the shooting direction of the camera 402.

  The display unit 110 renders a two-dimensional image obtained by photographing the virtual three-dimensional space with the camera 402, and generates a frame (two-dimensional image) arranged on the time axis. The definition of the operation of the camera 402 that captures a virtual three-dimensional space is used to define the rendering process. The background 406 may be a three-dimensional model, a two-dimensional image, or a moving image.

  Specifically, the model can be converted into a three-dimensional animation by defining the angle of view, focal length, direction, position, and the like of the camera 402 on the time axis. What defines the angle of view, focal length, direction, position, etc. of the camera 402 on the time axis is called “camera work”.

  FIG. 5 is a diagram showing an example of model components using the configuration of the user interface used when creating a three-dimensional animation. A user interface 500 for use in creating a three-dimensional animation is shown.

  The model includes character A 530, motion B 540, camera work C 550, sound D 560, and background E 570. Note that the components of the model in FIG. 5 are examples, and other components (for example, illumination, ambient light, etc.) may be included.

  A timeline 520 indicates the time of the three-dimensional animation 502. In the three-dimensional animation 502, a character A 504 and a background 506 are displayed.

  For example, an identifier of a character in which a skeleton model and a skin are defined is set in the character A 530. In FIG. 5, an identifier of a character defining a miniskirt girl is set. On the user interface 500, an image of a character associated with the identifier may be displayed in the A column.

A motion of the character is defined in the motion B540. Character motion may be defined discretely at several times. By interpolating on the time axis the character poses that are discretely defined in terms of time, the character A 530 can move smoothly. On the user interface 500, the name of the character may be displayed.

In the camera work C550, the angle of view, focal length, direction, position, etc. of the virtual camera 402 are defined on the time axis. Camera work may also be defined discretely at several times. The camera work C550 can be smoothly changed by interpolating the camera settings defined discretely in time on the time axis.

  In the sound D560, for example, sound information such as music is set. Specifically, an identifier for specifying acoustic information may be set. On the user interface 500, a music name may be displayed. A setting for changing the volume of acoustic information on the time axis may be added to the sound D560.

  In the background E570, an identifier for specifying the background 506 is set. The background E570 may be a two-dimensional image, a three-dimensional model, a moving image, or the like. A background name may be displayed on the user interface 500.

  The position on the time axis of the three-dimensional animation 502 is indicated by a time display line 524.

  The button 511 is a button for moving the time display line 524 to time zero.

  The button 512 is a button for moving the time display line 524 in the past.

  A button 513 is a button for reproducing a three-dimensional animation.

  The button 514 is a button for moving the time display line 524 to the future.

  The button 515 is a button for moving the time display line 524 to the final time.

  The model created as described above is downloaded from the server device to the client device, and the three-dimensional animation is played back on the client device.

  Note that the user interface 500 shown in FIG. 5 is a user interface used when creating a three-dimensional animation. Therefore, when reproducing a three-dimensional animation, the components, the time display line 524, and the like are displayed on the screen. May not be displayed.

  FIG. 6 is a diagram illustrating an example of a plurality of models 600 stored in the server device.

Each model (model 1 to model 4) has a character, motion, camera work, sound, and background as components. Depending on the model , some of these components may be missing. Moreover, these components are examples, and other components (for example, ambient light, illumination, etc.) may be included in the model.

  Model 1 has components of character A1, motion B1, camera work C1, sound D1, and background E1.

  The model 3 is a model having no background component. Model 4 is a model having no acoustic component.

  FIG. 7 is a diagram illustrating an example of processing for generating a new model by modifying a model. An example in which model 1 is modified is shown.

  Model 1 to model 4 shown in table 600 are stored in server device 120. The client device 100 downloads and stores the model 1 (610) and the model 2 (620).

  The client device 100 can modify the model 1 (610) based on a user instruction.

  Based on the user's instruction, the client device 100 replaces the motion B1 of the model 1 (610) with the motion B2 of the model 2 (620) to generate a model 11 (630).

  In this case, model 1 has an ancestor relationship of model 11 and model 11 has a descendant relationship of model 1 as shown in relationship 640.

  The client device 100 uploads the generated model 11 (630) to the server device 120. The model 11 (601) uploaded on the server device 120 is stored in the server device 120 so that it can be downloaded to the client device 100.

  Then, the client device 100 can generate and display a three-dimensional animation from the modified model 11 (630).

  The model 11 (601) uploaded to the server device 120 is provided to the other client device 100 by the server device 120.

  Further, the relationship 640 described above may also be uploaded to the server device 120 by the client device 100 and stored in the server device 120. Further, this relationship 640 may be provided to another client device 100 by the server device 120.

  FIG. 8 is a diagram illustrating another example of processing for generating a new model by modifying a model. FIG. 8 shows an example in which the model 11 uploaded to the server in the description of FIG.

  The server device 120 stores model 1 to model 4 (600) and model 11 (601). These models stored in the server device are downloaded to the client device 100 based on a request from the client device 100.

  The client device 100 downloads model 4 (650) and model 11 (670). The model 4 is a model that does not include acoustic components.

  Based on the user's instruction, the client apparatus 100 replaces the background E1 of the model 11 (670) with the background E4 of the model 4 (650), and generates a model 12 (680).

  In this case, model 11 has an ancestor relationship of model 12 and model 12 has a descendant relationship of model 11 as shown in relationship 690.

  The client device 100 uploads the generated model 12 (680) to the server device 120. The model 12 (602) uploaded on the server device 120 is stored in the server device 120 so that it can be downloaded to the client device 100.

  Then, the client device 100 can generate and display a three-dimensional animation from the modified model 12 (680).

  The model 12 (602) uploaded to the server device 120 is provided to the other client devices 100 by the server device 120.

  Further, the above-described relationship 690 may also be uploaded to the server device 120 by the client device 100 and stored in the server device 120. This relationship 690 may be provided by the server device 120 to another client device 100.

  FIG. 9 is a diagram for explaining the modification history of the modified model.

  FIG. 9A shows the relationship between model 1 and model 11 (640) and the relationship between model 11 and model 12 (690).

  FIG. 9B illustrates the relationship of the model 1 viewed from the model 11 and the relationship of the model 12 viewed from the model 11 from the relationship illustrated in FIG. That is, the model 1 has a recent ancestor relationship with the model 11. Model 12 has the closest offspring relationship to model 11.

  For example, when the client device 100 downloads the model 11 from the server device 120, the relationship in FIG. 6A may also be downloaded from the server device 120. By doing in this way, the client apparatus 100 can display what the immediate ancestor of the model 11 and the immediate descendant of the model 11 are. When displaying the relationship, the client device 100 may download and display the characteristic two-dimensional images of the three-dimensional animation of the model 1 and the model 12 from the server device 120 together.

  FIG. 10 is a diagram showing an example in which the model modification history is shown in a tree structure.

  The relationship shown in FIG. 9 indicates a relationship between models, and a single tree structure can be created from a plurality of relationships by combining a plurality of relationships. In this tree structure, it can be seen that the oldest ancestor is the model a.

  The client device 100 can download the tree structure relationship shown in FIG. 10 from the server device 120. For example, the client device 100 may display the oldest ancestor in addition to the latest ancestor and the latest descendant.

  By displaying such a relationship, the user can know the history of model modification. Also, the user can check the model modification history and download a favorite model from the server device 120. The user can search the model modification history by following the relationship.

  FIG. 11 is a diagram illustrating an example of a screen for selecting a model to be downloaded on the client device.

  A screen 1100 for selecting a plurality of models shows an example of a screen for selecting a model to be downloaded in the client apparatus 100.

  A column 1110, a column 1120, a column 1130, a column 1140, a column 1150, and a column 1160 display models that can be downloaded from the server device 120, respectively. The large image on the left side of each column shows a representative two-dimensional image of the three-dimensional animation of the model. By displaying such a representative two-dimensional image on the screen, the user can intuitively grasp the contents of the model. Instead of a representative two-dimensional image, a model ID or a model name (described later) may be displayed on the screen.

  “Sleeping person” 1112 is the name of the model. “Takeshi” 1114 is the name of the user who created the model or the modified model. The thumbnail image 1116 is an image that an arbitrary user has taken a snapshot of a three-dimensional animation of a “sleeping person” and uploaded it to the server device 120. Note that the model name, author, and snapshot do not have to be displayed on the screen.

  For example, the user can select a model having the name “sleeping person” by tapping the column 1110 with a finger. The model selection method is not limited to tapping with a finger. For example, clicking with a mouse, swiping with a finger, or inputting a model name by voice may be used.

  The selected model is downloaded from the server device 120 to the client device 100. The user can instruct downloading of one or more models using a screen 1100 for selecting one or more models.

  The downloaded model is stored in the client device 100. Depending on the capacity of the storage device of the client device 100, a threshold of the number of models that can be stored may be provided. When the number of models to be stored exceeds a threshold value, for example, the oldest downloaded model may be deleted to secure a storage area where the model can be stored.

  FIG. 12 is a diagram illustrating an example in which a three-dimensional animation is displayed on the client device using the downloaded model.

  The client device 100 can display a playback screen 1200.

  When the playback button 1230 is selected (instructed) by the user, the downloaded model displays a three-dimensional animation movie 1210 using the selected model. It is desirable that the three-dimensional animation is generated from the model in real time. The user can change the direction in which the character is displayed by operating the virtual camera 402 in real time. Note that the user interface for moving the virtual camera 402 in real time is not displayed in the drawing, but any user interface that allows the user to specify the angle of view, focal length, direction, position, etc. of the camera 402 can be used. It may be a thing.

  In the thumbnail area 1220, a plurality of two-dimensional images (thumbnails) at an arbitrary time of the three-dimensional animation may be displayed. For example, the user may be able to create a thumbnail image of a three-dimensional animation by pressing a predetermined button (not shown) at an arbitrary time. The created thumbnail image is displayed in the thumbnail area 1220. The plurality of thumbnail images may be arranged in order corresponding to the time axis of the three-dimensional animation. The created thumbnail may be uploaded to the server apparatus 120 in association with the model being played.

  The client device 100 may download thumbnails uploaded to the server device 120 by other users to the client device 100 and display them in the thumbnail area 1220. The thumbnail may be downloaded with the model download or may be downloaded at a different time than the model download. For example, when a 3D animation is generated, a thumbnail associated with a model may be downloaded from the server device 120 to the client device 100.

  For example, when the thumbnail 1221 is selected by the user and the playback button 1230 is pressed, the client apparatus 100 performs the tertiary operation with the camera work in which the thumbnail is acquired from the time of the selected thumbnail. An original animation may be generated and displayed.

  By doing in this way, the user can watch a three-dimensional animation with a favorite camera work from a favorite time.

  FIG. 13 is a diagram illustrating an example of a user interface displayed when selecting a component of a model.

  The client device 100 can display a screen 1300 for correcting the components of the model.

  The image 1310 is an arbitrary two-dimensional image of the three-dimensional animation of the model to be modified. As the image 1310, a characteristic two-dimensional image representing a model among the two-dimensional images of the three-dimensional animation may be determined in advance. It can be seen that there are five characters in the image 1310, and “Sea House” is the background.

  The “What to replace?” Display (1320) is a display prompting the user to indicate which component of the model components is to be replaced with another component.

  The screen 1300 displays components to be selected for replacement. Specifically, a character 1330, motion 1340, camera work 1350, background 1360, and audio 1370 are displayed in a selectable manner. As already mentioned, the components of the model are not limited to these. The model may not include all of these components. For example, a model that does not include the audio 1370 may exist. In this case, audio from another model may be added by selecting the audio 1370. Audio is an example of acoustic information.

  In addition, when the component of motion exists in the model, it is desirable that the component of character also exists. This is because it is difficult for a user to confirm a motion even if a model in which motion exists and no character exists generates a three-dimensional animation.

  FIG. 14 is a diagram illustrating an example of a user interface displayed when modifying a model.

  The client device 100 can display a screen 1400 and a screen 1450 for modifying the model.

  FIG. 14A shows a screen 1400 displayed when a character is replaced.

  On the screen 1400, five characters 1411 to 1415 are displayed, and a background 1410 is displayed.

  The display (1419) of “Which to replace?” Prompts the user to indicate which of the five characters is to be replaced.

  A column 1420 corresponds to the character 1413, and an enlarged image 1422 of the face of the character 1413 is displayed. A column 1430 corresponds to the character 1411 and displays an enlarged image 1432 of the face of the character 1411. A column 1440 corresponds to the character 1412 and displays an enlarged image 1442 of the face of the character 1412. The enlarged image of the character's face is a display for helping the user identify the character.

  A check mark 1444 indicates that the character 1412 has been selected for replacement by the user.

  FIG. 14B shows an example of a screen 1450 displayed when the user instructs which character the character selected in FIG. 14A is to be replaced.

  The screen configuration of the screen 1450 will be described below.

  An enlarged image 1472 of the face of the character “Kokeshi 1” is displayed in the field 1470.

  An enlarged image 1482 of the face of the character “Kokeshi 2” is displayed in the field 1480.

  An enlarged image 1492 of the face of the character “Ishida 1 Whole Tights Man_Yellow” is displayed in the field 1490.

  By the check mark 1474, the character column 1470 of “Kokeshi 1” is selected by the user.

  As a result of the above operation by the user, the character 1412 is displayed as a character 1452 replaced with “Kokeshi 1”. It can be seen that the other character 1451, character 1453, character 1454, and character 1455 are not replaced. The background 1460 is also displayed as not yet replaced.

  As described above, by alternately displaying the screen 1400 and the screen 1450, the user can instruct which character is replaced by which character. Note that the character candidates displayed on the screen 1450 may be selected by the user by scrolling the characters already included in one or more other models. Alternatively, the user may select a model that is a candidate for replacement, and the user may select a character included in the selected model. The model that is a candidate for replacement may be a model that has been downloaded from the server device 120 in advance. Alternatively, a model that is a candidate for replacement may be downloaded from the server device 120 according to the user's selection.

  Also, the background 1410 can be instructed by the user as to which background to replace by using the same interface screen as in FIG.

  The above-described user interface is an example, and the embodiment is not limited to these user interfaces.

  FIG. 15 is a diagram illustrating an example in which a model is modified by selecting a component to be modified.

  On the screen 1500, a check mark 1531 is assigned to the character 1530 and a check mark 1561 is also assigned to the background 1560 based on a user instruction. Therefore, it can be seen that the user has instructed that the character and background of the model components are to be replaced. Note that as described above, an additional instruction may be used instead of replacement. Further, the number of characters may be increased or decreased.

  The screen 1500 displays a two-dimensional image 1510 of the modified model after the character 1514 and the background 1512 are replaced. The female character 1412 is replaced with the Kokeshi 1 character 1514. The background 1410 of the sea house is replaced with a background 1512 in which plants are present.

  The model modified as described above may be uploaded from the client device 100 to the server device 120 based on a user instruction. In addition, when uploading is executed, the relationship between the model before modification and the model after modification may be uploaded.

  In addition, the user can further modify the modified model using the screen 1500.

  FIG. 16 is a diagram illustrating an example of a screen that displays a model modification history.

  The client apparatus 100 can display a screen 1600 that displays a model modification history.

  The image 1610 displays a two-dimensional image of a three-dimensional animation of the model selected by the user. Under the screen 1600, a plurality of thumbnail images of the selected model may be displayed.

  A two-dimensional image representative of the most recent descendant is displayed in a column 1621 below the “most recent descendant” display 1620. The display of “dance” is the name of the model. The display of “guest” is the name of the user who generated the model of the latest descendant.

  A two-dimensional image representing the nearest ancestor is displayed in a column 1631 below the “nearest ancestor” display 1630. “Dance on the beach” is the name of the model. “Guest” is the name of the user who created the model of the nearest ancestor.

  A two-dimensional image representing the oldest ancestor is displayed in a column 1641 below the “oldest ancestor” display 1640. The display of “Ishida 3” is the name of the model. The “bean” display is the name of the user who created the oldest ancestor model. In addition, the column 1641 displays a thumbnail image 1642 of a three-dimensional animation of the oldest ancestor model.

  For example, the user can download the oldest ancestor model from the server device 120 to the client device 100 by tapping the oldest ancestor with a finger. You can watch it. If the oldest ancestor model has already been downloaded, the download can be omitted and the three-dimensional animation of the oldest ancestor model can be viewed.

  The client apparatus 100 may download the tree structure modification history shown in FIG. 10 from the server apparatus 120 to the client apparatus 100 so that the user can search the modification history.

  Since the user can search the modification history, the user can display the three-dimensional animation of the related model on the client device 100.

  As described above, by using a plurality of modified models, various modified models can be easily generated by the user.

  FIG. 17 is a diagram illustrating a hardware configuration 1700 of the client device 100 and the server device 120.

  The hardware configuration 1700 includes a CPU 1710, a memory 1720, a communication control unit 1730, an input / output interface 1740, a display control unit 1750, a drive control unit 1760, and a print control unit 1770.
