2. Description of the Related Art In recent years, in television programs and movies,
Three-dimensional character animation using three-dimensional computer graphics technology has become popular, and many gate software and the like using this three-dimensional character animation have been produced. ing.

As the characters appearing in the three-dimensional character animation, a person, an animal, an anthropomorphic object, and the like are used in many cases. (Figure 1
8 (a)) is often expressed as a deformation of the skeleton structure (FIG. 18 (c)) due to a change in the joint angle and movement of the joint point of the skeleton structure (FIG. 18 (b)). . When the movement of the character is expressed by such deformation of the skeleton structure, FIGS. 19 (a) and 19 (b)
A multi-joint model is defined as shown in Fig. 3 and physical data such as the degree of change of the joint angle and the moving distance of the joint point corresponding to various movements are stored in a database in advance. By updating physical data such as the degree of change of the angle and the moving distance of the joint point, the movement is generated as needed. In the latter case, in order to use these updated physical data as data expressing the motion of the three-dimensional character, for example, in FIG. 19, the joint model shown in (a) is replaced with the joint model shown in (b). The physical data when the joint model is changed from (a) to (c) is replaced with the parts A, B, c, d, e, f, and Applying to the positions of the six vertices of g and h, from (b) of part A
Generate the movement to (d).

Also, unlike the world of simulation, the world of computer graphics does not necessarily have to match the real world, and deformations different from the real world are often used as effects of expression, and comical movements entertain the user. Used as an effect. Therefore, 3
In three-dimensional character animation, it is not always necessary to pursue strictness in physical data such as the degree of change in joint angles and the movement distance of joint points, and a simple deformed character is used without using complicated physical data. There is a need to generate motions of

Next, the operation will be described with reference to FIG. First, in the three-dimensional position calculating means 10, the three-dimensional grid space 2 is arranged in the three-dimensional space based on the three-dimensional grid space shape data describing the shape of the three-dimensional grid space 2, and the shape of the three-dimensional object 1 is changed. 3 described
3D showing the three-dimensional shape data and the time axis change of the correspondence between the joint points of the parts of the three-dimensional object 1 and the grid points.
The part A of the three-dimensional object 1 is arranged in the three-dimensional grid space 2 based on the three-dimensional motion data. At this time, 3
As the initial values of the dimensional motion data, the joint points Aa and Ab of the component A and the grid points W9 and W

9 and the joint point A of the central axis 3 which intersects with W18

Next, the texture mapping means 12 is used in accordance with the usual three-dimensional computer graphics technique.
The perspective transformation unit 13 projects the three-dimensional object 1 on which predetermined texture data is pasted from a coordinate position in a three-dimensional space onto a two-dimensional display surface (FIG. 5), and performs coordinate transformation to generate image data. Then, the image data is stored as frame data in the frame memory means 14, and the frame data is displayed by the image display means 15.

The above is the process of generating and displaying the initial frame. Similarly, the frame No., which is the frame indicating the first movement of the three-dimensional character, is displayed. Also, in the three-dimensional position calculation means 10, the three-dimensional grid space 2 in the three-dimensional space set when the initial frame was generated.
Without changing the position of the three-dimensional object 1 in the three-dimensional grid space 2 based on the three-dimensional motion data. At this time, as the first motion of the three-dimensional motion data, each joint point A-a,
2 and the correspondence between Ab and the grid points W6 and W18 are described.
As shown in (c), the central axis 3 is set at the grid points W6 and W1.
8, the arrangement is changed so that the grid point W6 is located on the joint point Aa side of the center axis 3 and the grid point W18 is located on the joint point Ab side.

This frame No. 0 and frame No. 1
As a result, one movement of the part A inclining rightward is generated. Similarly, the subsequent movement of the part A is also based on the three-dimensional motion data, based on the three-dimensional grid space 2.
Are generated by changing the arrangement of the three-dimensional object 1. In the subsequent three-dimensional computer graphics method, frame data is displayed by repeating the same operation in accordance with the above-described ordinary three-dimensional computer graphics method. Also, for the parts constituting the three-dimensional object 1 other than the part A,
As in the case of the component A, the motion of the entire three-dimensional object 1 is generated by the motion of each component, and is displayed as the motion of the three-dimensional character.

Here, the above-described three-dimensional position calculating means 10
In the description, it is assumed that the three-dimensional object 2 is covered with the three-dimensional grid space 2. In the above description of the operation, the three-dimensional position calculating means 10 first arranges the three-dimensional grid space 2 in the three-dimensional space, It is assumed that the three-dimensional object 1 is arranged in the three-dimensional grid space 2, and the order is reversed. However, in the latter description of the above operation, the three-dimensional grid space 2 is fixed in the three-dimensional space. Prior to these arrangements, the three-dimensional object 1 which is a three-dimensional character whose motion is to be generated is first arranged before the object 1.
To determine the three-dimensional grid space 2 assuming how to move the three-dimensional object 1,
The order is substantially the same as the former.

The parts A and B are rectangular parallelepipeds,
The joint points Aa, Ab, Ba, and Bb are:
The top of component A, the bottom of component A, the top of component B,
And the bottom point of the component B is set, but it is not always necessary to set the above point. However, it is preferable to set the two points at positions that are located on the surface of the part of the three-dimensional object and can take an axis formed by a straight line passing through the inside of the part.

Here, in the above description of the operation, every time the arrangement of the three-dimensional object 1 is changed in the three-dimensional grid space 2 based on the three-dimensional movement data, the generated three-dimensional object 1 Although the image data is displayed by the image display means 15 as frame data by the method of computer graphics, the three-dimensional position calculating means calculates the joint points when the three-dimensional object 1 is arranged based on the three-dimensional motion data. And the corresponding grid points are described in a correspondence table, and based on the three-dimensional motion data, the three-dimensional object 1
If the storage means for describing and holding the correspondence between the joint points and the grid points when the arrangement is changed in the time axis direction of the correspondence table as shown in FIG. By generating frame data, a predetermined frame rate, for example, 3
The movement of the three-dimensional object 1 can be displayed at a speed of 0 frame.

The three-dimensional calculation means 10 generates the motion of the three-dimensional object 1 by rearranging the three-dimensional object 1 in the three-dimensional grid space 2 based on the three-dimensional motion data. Instead of projecting onto the two-dimensional display surface, the three-dimensional grid space 2 and the three-dimensional object 1 are projected onto the two-dimensional display surface, and then, based on the three-dimensional motion data on the two-dimensional plane, the projected three-dimensional object is projected. The arrangement of the projected three-dimensional object 1 in the grid space 2 may be changed to calculate the movement of the three-dimensional object 1,
In this case, the amount of calculation can be reduced as compared with the case of performing calculation in three dimensions.

The shape of the parts of the three-dimensional object can be various shapes corresponding to the three-dimensional character, for example, a cylinder, a cube, a sphere, etc., in addition to the rectangular parallelepiped used above. Each component can be set to various shapes as a configuration including a plurality of components.

Therefore, the shape of the three-dimensional grid space,
That is, the arrangement of the grid points is appropriately set according to the shape of the three-dimensional object and the assumed movement of the three-dimensional object, and a three-dimensional grid having a sufficient size for the three-dimensional object is set. A space can be provided. The arrangement of the grid points can express a precise movement of the three-dimensional object if the space between the grid points is narrowed. However, in order to suppress the amount of data and generate a simple deformed character movement, the grid points are appropriately arranged. It is necessary to take wide points.

FIG. 6 is a diagram showing a three-dimensional character animation display device according to the first embodiment in which the shape of the three-dimensional grid space is changed.

In FIG. 6, the same reference numerals as those in FIG. 2 denote the same or corresponding parts. (A) shows the same one as in FIG. 2 (a). (b) is obtained by changing the rectangular parallelepiped three-dimensional grid space of (a) to a cylindrical three-dimensional grid space.
(c) shows the arrangement of the joint points Aa and Ab of the part A of (b) changed so as to coincide with the grid points W2 and W11, respectively.

Next, the operation of the three-dimensional character animation display device when the three-dimensional grid space whose shape has been changed is used will be described again with reference to FIG. As described above in the description of FIG. 3, the motion of the part A of the three-dimensional object includes, for example, the frame No. 1
Frame data up to 00 are generated. It is assumed that 100 corresponds to the correspondence between the joint points of the component A and the grid points shown in FIG. Therefore, based on the three-dimensional grid space shape data, 3
The shape of the rectangular parallelepiped three-dimensional grid space shown in (a) is changed to the cylindrical shape shown in (b) while the position of the component A of the three-dimensional object in the three-dimensional space is kept as it is. That is, (a) and
(b) is the same No. This corresponds to 100 frame data.
At this time, the information to change the shape of the three-dimensional grid space is included in the three-dimensional grid space shape data and also included in the three-dimensional motion data.
The two data are linked. Therefore, when the shape of the three-dimensional grid space is changed, the grid points of the changed three-dimensional grid space are also used for the three-dimensional motion data, and the joint points at the same location on the time axis are used for the three-dimensional motion data. Aa and Ab are grid points W9 and W1, respectively.
8 and grid points W1 and W, respectively.
10 is also described. Next, on the time axis of the three-dimensional motion data, the correspondence between the joint points Aa and Ab and the grid points W2 and W11, respectively, is described, and based on this, as shown in FIG. Part A
Is changed, and as described above, No. 2 is used in accordance with the method of three-dimensional computer graphics. 101 is generated. Similarly, based on the three-dimensional motion data, the joint points Aa and Ab are respectively set to grid points W3 and W12, W4 and W13, W5 and W1.
4, W6 and W15, W7 and W16, W8 and W1
7 and W1 and W10. 102, 103, 104, 105, 106, 10
7 and 108 are generated and the component A
Can move in parallel to draw a circle.

Here, in the cylindrical three-dimensional grid space, the joint points and the grid points are made to coincide with each other so that the component A
However, it is not necessary to make them coincide with each other, and as in the case of the rectangular parallelepiped three-dimensional grid space, the central axis, which is a straight line passing through the two joint points, intersects the grid point, and If the grid points are located outside, the grid points corresponding to the joint points may be separated.

In the case of the above-described parallel movement,
It is not necessary to make the two joint points correspond to the grid points, and it is possible to generate a movement in which the component A translates simply by setting one representative point for the component A. For example, 3
Information that a representative point is set at the center of gravity of the space of the part A included in the three-dimensional shape data describing the shape of the three-dimensional object, and the representative point and the grid point in the time axis direction described in the three-dimensional motion data W1, W2, W3, W4, W
According to the information of matching 5, W6, W7, W8, and W1, it is possible to generate a motion for translating the component A in the same manner as described above.

FIG. 7 is a diagram showing the three-dimensional character animation display device according to the first embodiment in which the distance between the joint point of the three-dimensional object and the grid point has been adjusted. 7, the same reference numerals as those in FIG. 1 denote the same or corresponding parts. Also, (a) shows that the center axes 3 of the parts A and B of FIG.
8 and the one that has been changed so as to pass through the grid points W18 and W20. (B) is the grid point W2 of the part A and the part B in the three-dimensional grid space of (a), , W6, W24, and W20 on a two-dimensional plane. (c) extends the component A and the component B in the axial direction of the central axis 3, respectively, and connects the joint points Aa, Ab, Ba, and Bb to grid points W6, W18, and W18, respectively. , And W20. (d) shows the positions of the parts A and B in the three-dimensional grid space of (c) on the two-dimensional plane including the grid points W2, W6, W24, and W20 in the three-dimensional grid space. is there.

Here, the distance between the joint point and the grid point is set to 0 by extending the part and making it coincide with the grid point, but for example from FIG.
(C), the parts A and B of the three-dimensional object are reduced in the axial direction of the central axis 3, respectively, and the joint points Aa, Ab, Ba, and B are reduced. -B must be matched with grid points W9, W18, W18, and W27, respectively, and the three-dimensional object is expanded or contracted depending on how the arrangement of the three-dimensional object is changed. Instead of the extension or reduction in the direction of the central axis, the distance between the joint point and the grid point may be changed by enlarging or reducing the shape of the three-dimensional object. Furthermore, the distance between the joint point and the grid point corresponding to the joint point does not have to be 0, and the parts constituting the three-dimensional object are not too far apart or the parts do not overlap. The distance may be set appropriately.

As described above, in the three-dimensional character animation display device according to the first embodiment, the three-dimensional position calculating means uses the three-dimensional grid space shape data to
The three-dimensional grid space is arranged in the three-dimensional space, and the parts constituting the three-dimensional object are moved based on the three-dimensional shape data and the three-dimensional movement data so that the center axis of the part intersects the grid point. It is arranged in a grid space, and based on the three-dimensional motion data, the arrangement of the parts is sequentially changed to generate the motion of the three-dimensional object.
Since the frame data is displayed by the image display means in accordance with the ordinary three-dimensional computer graphics method, the degree of change of the joint angle indicating the deformation of the skeleton structure connecting the joint points, the movement of the joint points An animation of a three-dimensional character can be easily created without using complicated data such as distance.
In addition, the three-dimensional position calculating means describes a representative point when the three-dimensional object is arranged and a corresponding grid point in a correspondence table based on the three-dimensional motion data, and further, based on the three-dimensional motion data. Since there is provided storage means for describing and holding the correspondence between the representative points and the grid points when the arrangement of the three-dimensional object is changed in the time axis direction of the correspondence table, the three-dimensional motion data which becomes the same frame data Regarding the part, the movement of the three-dimensional object can be displayed using the frame data without changing the arrangement of the three-dimensional object to generate the three-dimensional movement. Further, since the distance between the joint point and the grid point corresponding to the joint point was adjusted by expanding and contracting the part in the axial direction connecting the joint points of the part, the distance between the three-dimensional parts was too large. It is possible to remove the sense of incongruity that may occur in the display. Further, since the shape of the three-dimensional grid space is changed, it is possible to realize various movements of the three-dimensional object according to the characteristics of the shape of the three-dimensional grid space. Furthermore, three-dimensional grid space,
And, after projecting the three-dimensional object on the two-dimensional display surface, based on the three-dimensional motion data on the two-dimensional plane, rearranging the parts of the three-dimensional object after projection in the three-dimensional grid space after projection, Since the calculation of the motion of the three-dimensional object is performed, the amount of calculation can be reduced as compared with the case where the calculation is performed in three dimensions.

The three-dimensional parts A and B arranged in the three-dimensional grid space are changed to three-dimensional parts C and D having different shapes, respectively.

FIG. 9 is a block diagram showing the configuration of the three-dimensional character animation display device according to the second embodiment. 9, the same reference numerals as those in FIG. 3 denote the same or corresponding parts. Reference numeral 11 denotes a storage unit that stores a correspondence table generated by the three-dimensional position calculation unit in the time axis direction.

Next, the operation will be described with reference to FIG. In the three-dimensional position calculating means 10, the three-dimensional grid space is arranged based on the three-dimensional grid space shape data, and the selected grid point W9 is determined based on the three-dimensional object component data as shown in FIG. A between parts W18 and W18 and between W18 and W27
And a part B are arranged to form a three-dimensional object. Then, W9 and W18 are defined as joint points A9 and A18 of the part A, respectively, and W18 and W27 are defined as joint points B18 and B27 of the part B, respectively. The motion of the component A and the component B is generated based on the three-dimensional motion data indicating the time axis change of the correspondence between the joint point of the component to be the three-dimensional object and the grid point. Further, in the same manner as described with reference to FIG.
A predetermined texture data is pasted on the surface of the three-dimensional object 1 and the three-dimensional object 1
The image data projected onto the two-dimensional display surface by the perspective transformation means 13 is stored as frame data by the frame memory means 14 by projecting from the coordinate position in the two-dimensional space onto the two-dimensional display surface, and the image display means At 15 the frame data is displayed. By repeating the above steps, the motion of the three-dimensional character is generated and displayed. Next, within the time of the frame display cycle in which the frame data is displayed by the image display means,
As shown in FIGS. 8A and 8B, the three-dimensional parts A and B are changed to parts C and D, respectively, based on the three-dimensional object component data. At this time, the joint points of the parts C and D coincide with the joint points A9 and A18 of the part A and the joint points B18 and B27 of the part B, respectively. Therefore, the parts C and D are three-dimensional movements indicating the time axis change of the correspondence between the joint points and the grid points of the parts that are three-dimensional objects used when generating the movements of the parts A and B. Motion can be generated based on the data.

The three-dimensional position calculating means describes the joint points and the grid points corresponding to the joint points when a part to be a three-dimensional object is arranged in a correspondence table based on the three-dimensional motion data. A storage unit for describing and holding a correspondence relationship between the joint point and the grid point when the component is rearranged based on the three-dimensional motion data in a time axis direction of the correspondence table.

Alternatively, if data transmitted by a communication means such as a network, a telephone line, a wireless telephone line, and infrared communication is used, the three-dimensional movement of the three-dimensional object can be effectively performed with fewer parameters. Can be generated and displayed.

As described above, in the three-dimensional character animation display device according to the second embodiment, a three-dimensional grid space is arranged based on three-dimensional grid space shape data, and a plurality of grid points are selected as initial values. Based on the three-dimensional object component data, each part is arranged between the grid points to form a three-dimensional object, and the grid points are defined as joint points of each part. Since the frame data is displayed by the image display means, without using complicated data such as the degree of change of the joint angle indicating the deformation of the skeleton structure connecting the joint points, the moving distance of the joint points, etc. An animation of a three-dimensional character can be easily created, and based on the three-dimensional motion data described above. Since there is provided a storage unit for describing and holding the correspondence between the representative points and the grid points when the arrangement of the three-dimensional object is changed in the time axis direction of the correspondence table, the three-dimensional motion data of the same frame data is obtained. Regarding the portion, the movement of the three-dimensional object can be displayed using the frame data without changing the arrangement of the three-dimensional object to generate the three-dimensional movement. Further, within the time of the frame display cycle in which frame data is displayed by the image display means, the part is changed to a part having a different shape by matching the joint point of the part to be changed to the joint point of the part, Since the three-dimensional motion data of the part before the change is used, it is not necessary to set a three-dimensional object that is a three-dimensional character and set a three-dimensional grid space that matches the three-dimensional object. It is possible to efficiently generate three-dimensional motion data with only a few parameters of the three-dimensional component motion in the three-dimensional grid space, and to effectively generate and display the motion of the three-dimensional object. In addition, various three-dimensional objects can be generated, and 3
By using the dimensional motion data, it is possible to easily generate a motion of a three-dimensional character having a different form with a smaller data amount. Further, since the three-dimensional object component part data or the three-dimensional grid space shape data used is transmitted by the communication means, the three-dimensional movement of the three-dimensional object can be effectively performed with fewer parameters. Can be generated and displayed.

FIG. 3 shows a part A on a two-dimensional plane including W2, W6, W15, and W11. (B) shows that only the three-dimensional grid space including the partial center axis 19 is transformed without changing the partial center axis 19 according to the three-dimensional grid position change data which is a deformation parameter such as an affine transformation coefficient. W2 and W6 have been deformed so that they respectively move away from W9 in the horizontal direction. (c)
Is obtained by deforming a three-dimensional object using an affine transformation coefficient obtained by deforming the three-dimensional grid space. Here, the parts A, 3D of the three-dimensional object before deformation
In the part Aa of the three-dimensional object after the deformation, the partial center axis 19 does not change, and the joint points Aa and Ab of the part A before the deformation and the joint point Aa of the part Aa after the deformation Since -a and Aa-b coincide, there is no change in the correspondence between the joint points of the component A before deformation and the grid points and the correspondence between the joint points of the component Aa after deformation and the grid points. . Therefore, when the three-dimensional object after the transformation is replaced with a three-dimensional object in the three-dimensional grid space before the transformation, the three-dimensional object after the transformation also has the joint points and the grid points as described in the first embodiment. By changing the correspondence of the three-dimensional objects, the motion of the deformed three-dimensional object can be generated and displayed.

Here, the three-dimensional grid position change data, that is, the three-dimensional grid space to which a deformation parameter such as an affine transformation coefficient is applied will be described with reference to FIG. The only three-dimensional space that includes the partial central axis 19. The partial central axis 19 intersects with the central axis 3 formed by a straight line passing through the joint points Aa and Ab of the part A of the three-dimensional object, and is outside the space of the part A and It is a part of the central axis 3 sandwiched between the two shortest grid points from the joint points A-a and Ab. Therefore, the three-dimensional grid space to which the above affine transformation coefficients are applied is represented by grid points W1, W3, W, where the partial central axis 19 shown in FIG.

FIG. 12 is a diagram showing, on a two-dimensional plane, another example of the process of deforming the three-dimensional object in the three-dimensional character animation display device according to the third embodiment. 12, the same reference numerals as those in FIGS. 2 and 10 denote the same or corresponding parts. 10 (a) corresponds to FIG. 10 (a), and FIG. 10 (b) keeps the distance between the grid point W2 and the grid point W11 constant according to the affine transformation coefficient without deforming the partial central axis 19. The grid point W2 is moved away from the axis, the distance from the grid point W15 is extended, and the grid point W6 is moved away from the axis, and only the three-dimensional grid space including the partial central axis 19 is deformed. It was done. (c) is obtained by deforming the three-dimensional object using the affine transformation coefficient obtained by deforming the three-dimensional grid space. Note that the partial central axis 19 here is elongated, unlike the one shown in FIG. 10, but is not deformed, so the correspondence between the joint points before and after the deformation and the grid points is Joint point A before deformation
-A and Ab and grid point W9 and
W18 and the corresponding deformed joint points Ab-a,
And Ab-b and grid points W9b and W
18 are arranged on the straight line in the same order and maintain the correspondence. Therefore, the deformed three-dimensional object is reduced or the like to reduce joint points Ab-a and Ab-b.
To the joint points A-a and Ab before deformation.
When the three-dimensional object in the three-dimensional grid space before the transformation is replaced, the correspondence between the joint points and the grid points is changed for the three-dimensional object after the transformation as described in the first embodiment. The motion of the deformed three-dimensional object can be generated and displayed.

(A) corresponds to the one obtained by removing the two-dimensional grid planes indicated by the grid points W2, W9, W18 and W11 from FIG. 2 (d), and corresponds to the partial central axis 19 of the part A of the three-dimensional object. 3 shows a component A on a two-dimensional plane indicated by grid points W6, W15, W18, and W9 in a three-dimensional grid space including.
(b) shows only the three-dimensional grid space including the partial central axis 19 based on the affine transformation coefficients.
It is deformed by moving the grid point W6 so that 9 is expanded. (c) is obtained by deforming the three-dimensional object using the affine transformation coefficient obtained by deforming the three-dimensional grid space. Note that the partial central axis 19 here is extended but not deformed similarly to the one shown in FIG. 12, so the correspondence between the joint points before and after the deformation and the grid points is also the same as the joint point before the deformation. A-a and A
-B and the grid points W6 and W18 and the corresponding joint points Ac-a and Ac- after deformation.
b and the grid points W6c and W18 are arranged on a straight line in the same order and maintain a correspondence. Accordingly, the joint points Ab-a and Ab-b are made to match the joint points Aa and Ab before deformation by reducing the deformed three-dimensional object, and the three-dimensional object before deformation is reduced. When the three-dimensional object in the grid space is replaced, the deformed three-dimensional object is also changed by changing the correspondence between the joint points and the grid points as described in the first embodiment. Object movements can be generated and displayed.

The deformation of the three-dimensional object in FIG. 13 corresponds to the deformation of the three-dimensional object shown in FIG. 11B, and the three-dimensional object is deformed according to the deformation parameters applied to the three-dimensional grid space. Since the objects are separately deformed, as shown in FIG. 11B, the three-dimensional object is transformed into a grid space (grid points W4, W5, W7, W8, W17, W1) to which the deformation parameters are applied.

Similar to the arrangement change, instead of transforming the three-dimensional object in three dimensions and projecting it on the two-dimensional display surface as described above, projecting the three-dimensional grid space and the three-dimensional object on the two-dimensional display surface, The grid space may be deformed on the three-dimensional plane based on the deformation parameters, and the object may be deformed according to the deformation parameters. In this case, compared to a case where a transformation such as an affine transformation is performed in three dimensions, The amount of calculation can be reduced.

Further, as the deformation information of the three-dimensional grid space, information stored in an external storage device such as a CD-ROM or a DVD may be used. If a data transmitted by a line, a wireless telephone line, or infrared communication is used, a three-dimensional motion of the three-dimensional object can be effectively generated and displayed with fewer parameters.

As described above, in the three-dimensional character animation display apparatus according to the third embodiment, the three-dimensional object intersects with the central axis formed by the straight line passing through the two joint points of the part and forms the outside of the space of the part. In addition, only the three-dimensional grid space including the partial central axis that is a part of the central axis sandwiched between the two grid points that are the shortest from the joint point, according to the three-dimensional grid position change data,
The partial center axis is deformed without being deformed, and the three-dimensional object is deformed by using the three-dimensional grid position change data. The motion of the object can be generated and displayed, and the correspondence between the joint points of the parts of the three-dimensional object before and after the deformation and the grid points does not change. The motion of the deformed three-dimensional object can be generated and displayed in place of the three-dimensional object in the three-dimensional grid space. Further, after projecting the three-dimensional grid space and the three-dimensional object on the two-dimensional display surface, the grid space is deformed on the two-dimensional plane based on the deformation parameters, and the object is deformed according to the deformation parameters. Performing complicated calculations using the deformation parameters in three to two dimensions can reduce the amount of calculation. Further, deformation information such as a deformation parameter for deforming the three-dimensional grid space is:
Since the one transmitted by the communication means is used, the three-dimensional movement of the three-dimensional object can be effectively generated and displayed with fewer parameters. Although the affine transformation coefficient is used as the transformation parameter, the transformation parameter is not limited to this.

It may be information to which the movement of the three-dimensional character is added. In the former case, since the three-dimensional character is in a stationary state, all the motions of the three-dimensional character are generated based on the three-dimensional motion information from the three-dimensional motion generating means 29. In the latter case, the three-dimensional character has already moved, and this movement is changed by the three-dimensional movement information to generate a new three-dimensional character movement.

Reference numeral 43 denotes a three-dimensional deformation information generation unit that generates three-dimensional deformation information using the parameters obtained by the voice analysis unit 28 and outputs the generated three-dimensional deformation information to the three-dimensional object deformation unit. The operation in this case will be described. In the same manner as in FIG. 14, the performance data output from the decoding means 20 is processed and output from the speaker 26 as sound.

In the three-dimensional object generating means 41, three-dimensional graphics image data is created from the three-dimensional basic motion and three-dimensional model data obtained from karaoke software.
Also, similarly to FIG. 14, parameters obtained by analyzing the microphone input signal are used. However, unlike FIG. 14, three-dimensional deformation information is generated by the three-dimensional deformation information generating means 43.
