Abstract

A first space (202) and a second space (203) are set in a 3D space (200). A 3D object (210) is animated from position P1 to position P2 in the second space (203) and further animated from position P2 to position P3 while reducing the size. A very long distance is set between the first space (202) and the second space (203). On the reproduction side, a 3D graphic animation thus defined is offset in the 3D space (200). When the 3D graphic is observed from a viewpoint (201), the animation is not varied significantly in the second space (203) before and after the offset and final position P3 shifted significantly.

 3D graphic display system and display device, and electronic message transfer system and display device

 Technical field

 The present invention relates to 3D graphic data production and playback technology.

 Background art

 There is an electronic mail system using 3D (three-dimensional) graphics. Japanese Patent Application Laid-Open No. 2004-23 4614 or Japanese Patent Application Laid-Open No. 2004-234614 discloses an electronic mail transmission / reception method using 3D data. There are also systems that use 3D graphic animation as e-mail content. By playing 3D graphic animation on the terminal that received the e-mail, it is possible to exchange electronic messages with various added value and high added value.

[0003] For example, in a receiving terminal, there is not much technical problem in reproducing 3D graphic animation at a fixed position. If the sending terminal sends data specifying the 3D graphic animation to be played back on the receiving terminal. The receiving terminal specifies the 3D graphic animation to be played based on the received data! Then, the receiving terminal only needs to play the specified 3D graphic animation at a fixed position.

 [0004] When trying to change the playback position of a 3D graphic animation in real time, several problems occur. For example, consider an e-mail in which a 3D graphic animation is embedded in a text sentence. In this case, the receiving terminal displays the text sentence in order and then displays the 3D graphic animation, but the display position is various. In other words, the position where the 3D graphic animation is displayed is at the beginning of the line, in the middle of the line, at the end of the line, at the first line, or at the end of the sentence.

[0005] Here, a case where a 3D graphic animation as shown in FIG. 12 is operated will be described. This 3D graphic animation creates a star-shaped 3D object 81 It is defined to move to the center of the display device (display) 70 while drawing.

 [0006] For example, if the display position of the 3D graphic animation embedded in the text sentence is just the center of the display device 70, the animation may be performed as shown in FIG. However, when the position where the 3D graphic animation is to be displayed (more precisely, the position where the 3D graphic animation is to be finally moved) is at the beginning of the line, that is, on the left side of the display device 70, as shown in FIG. In addition, the 3D graphic animation must be offset to the left as a whole. When the whole is offset in this way, there arises a problem that the 3D object 81 jumps out of the drawing area of the display device 70 while the trajectory 82 2m is being drawn.

 In order to solve such a problem, a method of preparing a 3D graphic animation as shown in FIG. 14 in advance can be considered. In other words, as a trajectory that the 3D object 81 animates, a common trajectory 82a and a plurality of trajectories 82b that finally move to various positions on the display device 70 are prepared. In the figure, three trajectories 82b are temporarily displayed, but it is necessary to prepare animation definition data corresponding to a large number of trajectories 82b so as to cover the entire display device 70. According to this method, it is possible to reproduce the 3D graphics that move to various positions while keeping the animation of the 3D object 81 within the screen of the display device 70. There is a problem that the amount of data becomes very large.

[0008] As another solution, the method shown in FIG. 15 is conceivable. In this method, one piece of 3D graphic data similar to that shown in Fig. 12 may be prepared. When the 3D graphic animation is played back, the trajectory 82 is dynamically converted into the trajectory 82t. According to this method, it is possible to reproduce 3D graphic animation that finally moves to various positions without increasing the amount of data. However, when a 3D graphic animation is played back, it is necessary to be able to manipulate the data structure dynamically in order to dynamically control the animation behavior of the 3D engine. Therefore, there is a restriction that it depends on the environment. In addition, a 3D engine that can dynamically manipulate data structures has a problem that the processing load is higher than a 3D engine that does not. Disclosure of the invention

 The present invention relates to a system for displaying 3D graphics on a display device. The system includes a generation unit that generates 3D graphic data for animating an object in a 3D space, and a display unit that displays a 3D graphic animation on a display device based on the 3D graphic data. In the 3D space where the 3D graphic data is defined, a first space and a second space are set. The 3D graphic data is stored in the second space force after the object is animated in the second space. Data that is defined to move to a predetermined position on the first space, and that draws a viewpoint force object in which the first space is on the near side and the second space is on the far side The display means is defined by means for determining the final display position of the object on the display device and 3D graphic data. Comprising a by parallel movement offset with 3D graphics animations in the 3D space, and means for a predetermined position is controlled match so the final display position.

 [0010] According to the present invention, it is possible to change the final movement position without much changing the animation in the second space. Therefore, it is possible to animate an object to various end points by simply performing an offset operation on the 3D graphic animation.

 [0011] In a preferred embodiment of the present invention, the objects include 3D objects. This makes it possible to animate a 3D object to a desired end position.

 [0012] In another preferred embodiment of the present invention, a 3D graphic is used so that the size of the object observed from the viewpoint does not change in the process in which the object moves to a predetermined position on the first space as well as the second spatial force. Data is defined to move objects while shrinking.

 [0013] Thereby, it is possible to provide a pseudo display effect in which an object is animated in a plane.

[0014] Therefore, an object of the present invention is to animate a 3D object that can be moved to various positions without increasing the amount of data and without increasing the calculation load in the drawing area of the display device. The purpose is to provide technology. [0015] Objects, features, aspects, and advantages of the present invention will become apparent from the following detailed description and the accompanying drawings.

 BEST MODE FOR CARRYING OUT THE INVENTION

[0017] {3D graphic data production power supply flow}

Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figure 1 shows 3D (3rd order Original) It is a diagram showing a series of flow until the production power of graphic animation is also supplied.

[0018] In the content production company 1, the CG creator 1 uses the computer 2 to produce the 3D darling data 253 (see FIG. 2). The 3D graphic data 253 produced by the content production company 1 is supplied to the mobile phone company 3. The mobile phone company 3 inserts the 3D graphic data 253 supplied from the content production company 1 into the mobile phone device 4 to be sold. (The 3D graphic data installed in the mobile phone device 4 is referred to as 3D graphic data 51.) _{0 In} addition, the 3D engine 52 and 3D mail program 53 required to play the 3D graphic data 51 in the mobile phone company 3 53 Is incorporated into the mobile phone device 4.

 The mobile phone device 4 on which the 3D graphic data 51, the 3D engine 52, and the 3D mail program 53 are installed is sold to the market by the mobile phone company 3. Then, the user uses the purchased mobile phone device 4 to exchange 3D graphic mail. 3D darling mail is sent and received via a network 5 consisting of a telephone network and the Internet.

 Alternatively, the 3D graphic data 253 produced by the content production company 1 may be stored in a storage medium such as a flash memory and supplied to the user of the mobile phone device 4. Alternatively, the 3D graphic data 253 may be stored in a server connected to the network 5 and downloaded and acquired by the user of the mobile phone device 4.

 [0021] {Content production}

 FIG. 2 is a functional block diagram of the computer 2 used by the CG creator 1 in the content production company 1. The computer 2 includes a CPU 21, a RAM 22, an operation unit 23 including a keyboard and a mouse, a display unit 24 such as a liquid crystal display, and a storage device 25 such as a hard disk. The computer 2 is, for example, a personal computer. Or, a dedicated computer that produces computer graphics is used.

[0022] The storage device 25 stores a 3D graphic production program 251 for producing 3D model data and animation definition data, and a 3D engine 252 for processing 3D graphics. In addition, the storage device 25 stores the produced 3D graphic data. Is stored.

 [0023] In this specification, 3D graphic data includes 3D model data and animation definition data. The 3D model data is data that defines a 3D object, and the animation definition data is data for giving movement and deformation to the 3D model data. In other words, the 3D model data defines the 3D shape, size, color, etc. of the 3D object to be displayed, and the animation definition data rotates, enlarges, or moves the 3D object defined by the 3D model data. This is data that defines the processing to be performed or transformed.

 Next, the contents of characteristic processing of the present invention will be described. FIG. 3 shows a virtual 3D space 200 defined when 3D graphic data 253 is produced using the 3D graphic production program 251 in the computer 2. In the 3D space 200, a first space 202 and a second space 203 are arranged. In this embodiment, the first space 202 and the second space 203 are planes parallel to each other. However, the first space 202 and the second space 203 may be a 3D space.

 [0025] The 3D graphic production program 251 also sets the viewpoint 201 in the 3D space 200. The 3D graphic data 253 produced in the 3D space 200 is actually drawn on the display device as a 2D graphic observed from the viewpoint 201. Viewpoint 201 is sometimes referred to as the camera position.

 [0026] As shown in the figure, in the 3D space 200, the distance a between the viewpoint 201 and the first space 202 is set to be shorter than the distance b between the viewpoint 201 and the second space 203. Has been. That is, the first space 202 is set on the short distance side with respect to the viewpoint 201, and the second space 203 is set on the long distance side.

 More preferably, in the 3D space 200, the distance a between the viewpoint 201 and the first space 202 is set to be sufficiently shorter than the distance b between the viewpoint 201 and the second space 203. In this embodiment, a: b = 1: 100 is set!

FIG. 4 is a diagram illustrating an example of the 3D object 210 defined in the 3D space 200. The 3D object 210 is defined by 3D model data. Here, the 3D object 210 is a three-dimensional star-shaped 3D graphic. FIG. 5 shows the contents of the animation definition data that gives motion to the 3D object 210 shown in FIG. 4 through the animation operation. The animation definition data is defined so that the 3D object 210 is first animated in the second space 203 along the locus 211 in the figure. That is, the 3D object 210 is displayed at the position P1 and then moves along the locus 211 to the position P2. Further, the animation definition data is defined such that the 3D object 210 is animated along the trajectory 211 in the second space 203 and then moved to the first space 202 along the trajectory 212. That is, the 3D object 210 moves from the position P2 toward the position P3. Then, the 3D object 210 finishes the animation operation at the position P3 in the first space 202 (here, the approximate center position of the first space 202).

 [0030] Further, while the 3D object 210 moves from the position P2 to the position P3, the size of the 3D object 210 is gradually reduced so that the size of the 3D object 210 viewed from the viewpoint 201 does not change. Defined in the animation definition data. Specifically, since a: b = 1: 100, the 3D object 210 in the second space 203 has a size that is 100 times the size of the final display of the 3D object 210 in the first space 202. (In FIG. 5, the ratio of a: b is not accurately represented. However, in reality, the size of the 3D object 210 is 100 in the second space 203 as compared with that in the first space 202. O) And when the 3D object 210 moves on the trajectory 212 to the position c (a c c b) from the viewpoint 201, the size of the 3D object 210 is the first space It is defined as cZa times the size in 202.

 When the 3D object 210 performs an animation operation using the animation definition data described above, the state of the 3D object 210 observed from the viewpoint 201 is as shown in FIG. That is, in the process of moving from position P1 → P2 → P3, the size of the 3D object 210 is constant, and after drawing the trajectory 211, the position moves from position P2 to position P3. This movement from the position P2 to the position P3 corresponds to the projection of the trajectory 212.

[0032] When the 3D graphic data 253 including the 3D model data and the animation definition data as described above is produced in the content production company 1, as described above, this data is converted into the 3D graphic data 51. Built into mobile phone device 4 as The A user who has purchased the cellular phone device 4 uses this 3D graphic data 51 to exchange 3D graphic mail.

 [0033] {Exchange of 3D graphic mail}

 Next, 3D graphic mail exchange processing will be described. Here, as described above, a case will be described in which 3D graphic mail is exchanged between the mobile phone devices 4 and 4 in which the 3D graphic data 51, the 3D engine 52, and the 3D mail program 53 are installed.

 FIG. 7 is a functional block diagram of the mobile phone device 4. The cellular phone device 4 includes a CPU 41 that performs overall control of the cellular phone device 4, a RAM 42 that is used as a buffer area when various programs are executed, an operation unit 43 that includes a crosshair cursor, alphanumeric buttons, and the like. In addition to displaying numbers and emails, the display unit 44 displays various types of information, the communication processing unit 45 performs voice communication and data communication, the antenna 46 that transmits and receives radio waves to and from the base station, and the storage device 47 A microphone 48 and a speaker 49 are provided.

 As the display unit 44, for example, a liquid crystal display is used. As the storage device 47, for example, a ROM such as a flash memory is used. As described above, the storage device 47 stores the 3D graphic data 51, the 3D engine 52, and the 3D mail program 53 when the mobile phone device 4 is shipped. However, as described above, these data may be provided via a storage medium that can be attached to and detached from the cellular phone device 4, or the data may be obtained by downloading server power on the Internet. .

 In the mobile phone device 4 on the transmission side, the 3D mail program 53 is used to perform a 3D graphic mail input operation. Here, a case will be described in which the user performs a 3D graphical email input operation as shown in FIG.

[0037] The user first operates the operation unit 43 to input text characters. For example, enter the words “Today is very fun and fun”. Subsequently, the user operates the operation unit 43 to perform a 3D graphic animation designation operation. Here, a star-shaped 3D graphic animation is designated by the user, and as shown in the figure, a star-shaped 3D object 210 is displayed following the inputted text characters. In addition, the user enters the text character “Let's go play again. Finally, the star-shaped 3D graphic animation is specified again. As a result, a star-shaped 3D object at the end of the sentence 210 is displayed. Here, the 3D graphic data 51 corresponding to various 3D graphic animations is prepared in the force storage device 47 in which the same star-shaped 3D graphic animation is specified, and the user can freely select these. Can be specified.

 When the 3D graphic mail as shown in FIG. 8 is created in the mobile phone device 4 on the transmission side, this 3D graphic mail is then transmitted. The mail data to be sent includes text character data and data specifying 3D graphic animation (that is, data specifying 3D graphic data 51). In other words, in this embodiment, since it is assumed that the transmitting side and the receiving side have the same 3D graphic data 51, it is not necessary to transmit the 3D graphic data 51 itself. Only data that specifies is sent. However, the transmission side power may be a method of transmitting the 3D graphic data 51 to the reception side.

 [0039] The mobile phone device 4 on the receiving side acquires text character data and data designating 3D graphic animation from the received mail data. Then, the 3D mail program 53 reproduces the 3D graphic mail using the received data.

 [0040] A method of reproducing 3D graphic mail will be described. The received 3D graphic mail is a text sentence in which 3D graphic animation is embedded. And the display position of the 3D graphic animation (more precisely, the final display position) varies. Therefore, in the mobile phone device 4 on the playback side, as shown in FIG. 9, the final movement position of the 3D object 210 is variously changed by offsetting the 3D graphic animation as a whole.

 FIG. 9 shows a 3D graphic animation in the default state (indicated by a bold line in the figure).

) And an offset 3D graphic animation (indicated by a dashed line in the figure). In the 3D graphic animation in the default state, as shown in FIG. 5, the 3D object 210 moves from the position P1 to the position P2 along the locus 211, and moves from the position P2 to the position P3 along the locus 212. Offset animation is the default The movement of the animation is translated in the 3D space 200 as a whole so that the final moving position of the 3D object 210 is the position P3 ′. In other words, the 3D object 210 is first displayed at the position P1 ′, moves along the locus 21 lm to the position P2 ′, and moves along the position P2 ′ force locus 212m to the position P3 ′.

[0042] In this way, the process of offsetting the 3D graphic animation defined by the 3D graphic data 51 as a whole in the 3D space 200 is generally performed by playing software without manipulating the data structure of the 3D graphic data 51. Side force can also be controlled. In other words, the entire operation of the 3D graphic animation can be offset by the processing of the 3D engine 52 or the 3D mail program 53.

 FIG. 10 shows a graphic obtained by observing the offset 3D graphic animation from the viewpoint 201 in this way. As shown in the figure, in the 3D graphic animation drawn on the display unit 44, the trajectory from position P1 'to position P2' approximates the trajectory from position P1 to position P2 shown in FIG. The trajectory from position P2 'to the position P3' is also very different from the trajectory from position P2 to position P3. This is because the entire space of the 3D graphic animation is offset by the same distance. Since the second space 203 viewed from the force viewpoint 201 is set very far away, the offset on the second space 203 is set. The distance of the robot is also a force that becomes a very short distance when projected onto the first space 202. For example, in this embodiment, since a: b = 1: 100 is set, the offset distance on the second space 203 is reduced to 1/100 on the first space 202. It is. Therefore, even if the position P3 is largely moved to the position P3 ′ on the first space 202, the motion of the animation on the second space 203 is not changed so much.

With reference to FIG. 11, a description will be given of a procedure for reproducing the received 3D graphic mail. The 3D mail program 53 first displays text characters in order. Here, the text “It was very fun today” is displayed (Fig. 11 (a)). Next, when the data specifying the 3D graphic animation is read, the 3D mail program 53 reads the corresponding 3D graphic data 51 from the storage device 47 and plays back the 3D graphic animation (Fig. Ll (b), (c) ). Here, finally, the star-shaped 3D object 210 Since we want to display it at the end of the line (upper right of display 44), offset the 3D graphic animation so that the final position P3 of the animation defined in 3D graphic data 51 matches the upper right of display 44 Play while playing. In this case as well, the animation behavior in the second space 203 does not change significantly, and as shown in the figure, the star-shaped 3D object 210 is animated without protruding the drawing area of the display unit 44 (see FIG. 11 (b)), and finally the display unit 44 moves to the upper right part (FIG. 11 (c)).

[0045] Subsequently, the 3D mail program 53 displays a text string "Let's go play again. Then" (Fig. 11 (d)). Next, when the data specifying the 3D graphic animation is read, the 3D mail program 53 reads the corresponding 3D graphic data 51 from the storage device 47 and plays back the 3D graphic animation again (FIG. 11 (e), ( f)) ₀ Here, we want to finally display the star-shaped 3D object 210 in the third row (upper center of the display 44), so the animation defined in the 3D graphic data 51 Play the 3D graphic animation while offsetting it so that the final position P3 coincides with the upper center of the display 44. In this case as well, the animation operation in the second space 203 does not change significantly, and as shown in the figure, the star-shaped 3D object 210 animates without protruding the drawing area of the display unit 44 ( FIG. 11 (e)), finally, moves to the upper center of the display 44 (FIG. 11 (f)).

 As described above, according to the present embodiment, the 3D object 210 can be finally moved to various positions on the receiving side without protruding from the drawing area. On the receiving side, only the offset operation of the 3D graphic animation is performed, so that the final movement position can be changed in real time with a small processing load. In addition, the processing for offsetting 3D graphic animation can be performed on the application side during playback processing without the need to manipulate the data structure of 3D graphic data with a general 3D engine, so it does not depend on the environment. It is a universally available technology.

 [0047] {Variation]

In the above embodiment, the 3D graphic animation described above is the force that describes the case where the 3D object animates. Even if it is something to shill.

 [0048] In the 3D graphic animation described in the above embodiment, the 3D object 210 moves toward the first space 202 after reaching the first space 202 after the animation in the second space 203. The final location was P3. This is an example. After the 3D object 210 animates in the second space 203, the 3D object 210 moves to the first space 202, and further animates in the first space 202, and then reaches the final position P3. It may be something that moves. However, when the animation is performed in the first space 202, it is preferable not to make a large movement because the animation may protrude from the drawing area when offsetting.

 [0049] In addition, the 3D graphic animation described in the above embodiment has been described for the case where the 3D object 210 moves to the final position P3 and the animation ends. This is an example, and the 3D object may continue to animate with a small movement after moving to the final position P3. For example, an animation that repeats small movements and small deformations may continue.

 [0050] Further, in the above embodiment, the receiving terminal embeds and displays the 3D graphic animation in the text text, but the text text display mode is particularly limited. Is not to be done. As with normal e-mail, text data can be displayed as is !, or text text can be replaced with 3D characters.

 [0051] The 3D mail program 53 may be a program having a function for creating or playing 3D mail by itself! /, And it is added to the standard mail program installed in the mobile phone device. It may be an additional program of the type.

 [0052] Also, in the above embodiment !, the 3D graphic animation to be played back by the mobile phone device 4 on the transmission side is designated. As an alternative method, the sender sends an e-mail that only has text text, and the receiver detects a keyword in the text sentence and plays a 3D graphic animation corresponding to this keyword. Even so, the present invention is applicable.

[0053] In this case, a predetermined keyword, 3D graphic data, and What is necessary is just to make it have the database which matched. For example, if you associate 3D graphic data that a star-shaped 3D object animates with keywords such as “fun” and “happy”, if these keywords exist in the text of the received email, The keyword can be converted into 3D graphic animation and displayed by processing only on the receiving side. In other words, the receiving terminal extracts keywords registered in the 3D graphic database from the text text of the received e-mail. Then, 3D graphics database force 3D graphic data corresponding to the extracted keywords acquired, the keyword parts in the text sentence is to display by replacing the ₃ D Dara Fick animation.

 [0054] Also in this case, the location of the keyword in the text sentence is not known until the mail is displayed, but the final movement of the 3D graphic animation is performed in real time while displaying the text sentence. By determining the position and offsetting the 3D graphic animation, it is possible to move the 3D object to the desired position.

 [0055] This invention has been described with reference to the embodiments shown in the accompanying drawings. This invention is not intended to be limited by the detailed description, except as otherwise indicated. It is intended to be broadly configured in scope.
