Each of the motion database 8 and the character database 9 is constituted by a CD-ROM and a rewritable semiconductor RAM, or at least one is constituted by a rewritable optical disk.

The character database 36 on the server side
The character database 9 on the terminal side stores data on various types of three-dimensional characters. For example, various skeleton models of a three-dimensional character, data of each part composed of polygons such as arms, legs, face, and body, textures, and the like are stored.

However, character databases 36 and 9
The character data stored in the server does not always match, and the character database 3 on the server side
6, some character data is not stored in the character database 9 on the terminal side.

The terminal 32 is connected to the server 3 if necessary.
1 can be requested to transfer character data not included in the character database 9 via the network 33.

On the other hand, the movement database 37 on the server side
The terminal-side motion database 8 stores various motion data corresponding to three-dimensional characters. For example, if the skeletal models indicating the lengths of the limbs and the like of the three-dimensional character are different, the movements of the limbs and the like corresponding thereto are also different. 8

However, the motion data included in the motion databases 37 and 8 do not always match,
Some motion data is not included in the terminal-side motion database 8 even in the server-side motion database 37.

The terminal 32 is connected to the server 3 if necessary.
1 can be requested via the network 33 to transfer motion data not included in the motion database 8.

What is transferred from the server 31 to the terminal 32 is the scenario data 51 and, if there is a special request from the terminal 32, character data or motion data.

FIG. 2A shows the structure of the scenario data 51. The scenario data 51 includes character designation information, motion data designation information, lighting designation information, and camera condition designation information.

The character designation information designates character data in the character database 9 of the terminal 32. The motion data designation information designates motion data in the motion database 8 of the terminal 32. The motion data designation information may designate one piece of motion data or may designate a time series combination of a plurality of pieces of motion data and provide information for newly creating a long-time character motion.

The lighting designation information designates the condition of the light source for illuminating the character, for example, whether it is a spotlight or a parallel light. The camera condition specification information specifies conditions such as the position, angle, and zoom of the camera that projects the character.

[0038]

[Table 1]

Table 1 shows the structure of the motion designation information in the scenario data. In Table 1, scene numbers Si are listed in the horizontal direction. One motion data Mi and a time width Ti occupied by the motion data are designated for one scene number.

FIG. 5 shows a flowchart of the processing of the terminal 32. 4 and 5, the scenario data 51 is shown.
Has already been downloaded from the server 31 to the terminal 32.

In FIG. 5, in (step 101),
The scenario data 51 is read into the terminal 32. In (Step 102), the data search means 1 searches the motion database 8 to check whether there is motion data specified by the motion data specifying information of the scenario data 5, and determines the result in (Step 103).

If it is determined in step 103 that the data does not exist, the data requesting unit 2 requests the server 31 to download the missing motion data in step 105.

The server 31 transfers the motion data to the terminal 32 according to the request from the terminal 32. The terminal 32 receives the insufficient data sent in (Step 106), and then proceeds to the execution of (Step 104).

If it is determined in (step 103) that the data exists, (step 104) is executed. In (step 104), the operation sequence control means 3 combines the motion data as specified in the scenario data 51 to generate a series of motion data, and the display control means 6
Sends the character's posture to the character posture control means 4 at the subsequent stage in accordance with the timing of transferring the image to the image display means 7.

FIG. 3 shows an example in which a plurality of pieces of motion data are combined according to the motion designation information shown in (Table 1). In FIG. 3, the movement indicates the movement of the skeleton of the character for the sake of simplicity. By way of example, motion data M1, M2 and M3
Were chronologically combined.

The motion data M1 indicates that the character moves from a state in which both hands are lowered to a posture in which the right foot is kicked up and the left hand is raised to the level of the chest, and then both hands are raised to the level of the chest and both feet are attached to the ground. This is motion data.

The motion data M2 includes a posture in which both hands are raised to the height of the chest and both legs are on the ground, a posture in which the left foot is kicked up and the right hand is raised to the height of the chest, and then both hands are raised to the height of the chest. This is motion data for moving the character to a posture in which is attached to the ground.

The motion data M3 is motion data for moving the character from a posture in which both hands are raised to the height of the chest and both legs are on the ground, and a posture in which both hands are raised slightly to the height of the head. Each is a short-time movement, but by combining them, the character can be moved for a long time. When the motion data M1, M2, and M3 are combined, the motion sequence control means 3 performs smooth motion as a whole by spline interpolation.

After (Step 104), (Step 1)
07) is executed. In (Step 107), the data search means 1 searches the character database 9 on the terminal side to check whether the character designated by the scenario data 51 exists, and determines the result in (Step 108).

If it is determined in step (step 108) that it does not exist, step (step 110) is executed. In (Step 110), the data requesting unit 2 requests the server 31 to download the missing character data.

The server 31 transfers the character data to the terminal 32 according to the request of the terminal 32. The terminal 32 receives the insufficient data sent in (Step 111), and then proceeds to the execution of (Step 109).

If it is determined in (Step 108) that the data exists, (Step 109) is executed. In (109), the character posture control means 4 controls the posture of the character to the posture designated by the motion sequence control means 3. Next, in (Step 112), the animation generating means 5 performs rendering calculation of the three-dimensional character using the lighting designation information and the camera condition designation information in the scenario data 51.

In (step 113), the display control means 6
Causes the image display means 7 to display the three-dimensional character rendered by the animation generation means 5. As described above (Embodiment 1), since the data transferred from the server to the terminal 32 is the scenario data 51 having a small data volume, the communication time is short. If the data is insufficient, the character data or motion data that was missing is transferred only at that time, so the communication time is shorter than in the conventional case where character data and motion data were transferred each time. it can.

(Embodiment 2) FIG. 6 shows an outline of a three-dimensional character display device according to (Embodiment 2) of the present invention.
Is connected to

8 is a terminal-side motion database, 9 is a terminal-side character database, 35 is a server-side scenario database, 36 is a server-side character database, 37 is a server-side motion database, 52
Is a scenario data request signal, and 53 is identification information.

Server-side character database 3
6. The character database 9 on the terminal side, the motion database 37 on the server side, and the motion database 8 on the terminal side are the same as those in the first embodiment, and thus description thereof is omitted.

The scenario data 51 is transferred from the server 31 to the terminal 32 via the network 33. FIG. 7 shows the data structure of the scenario data 51.
FIG. 7A shows the data structure of the scenario data 51, which includes character designation information, motion data designation information, lighting designation information, and camera condition designation information. The character specification information specifies character identification information, and the motion data information specifies motion data identification information.

FIG. 7B shows the data structure of character designation information. A character is selected by specifying the character identification information.

[0060]

[Table 2]

(Table 2) shows character identification information, which is composed of a character skeleton model designation code (vertical axis in Table 2) and a character region designation code (horizontal axis in Table 2). The character differs depending on the skeleton, such as the length of the limbs and the ratio of the torso to the limbs. Therefore, even for the same male, the lean skeleton model, the obese skeleton model, and the tall skeleton model are different from each other, and the skeleton model designation codes are given separately. In addition, even for men and adults, different skeleton model designation codes are given because the ratios of the skeletons of the limbs, the torso, and the head are different between adults and children.

Similarly, since the skeletons of males and females are different even in adults, the male skeleton model and the female skeleton model are given by different skeleton model designation codes. While the skeleton model is the skeleton of the character, the character parts are the head, chest, waist, both arms, and both legs attached to the skeleton, and the character is completed by attaching the character parts to the skeleton model .

The same skeletal model becomes another character by changing the shape of the character part, for example. For example, by making the head a singer A or a singer B, it is possible to create another character having a different head including a face and a hairstyle for the same skeleton model. The part shape specification code specifies a specific shape of the part. Less than,
The same applies to the chest, waist, arms and legs.

Therefore, a character can be selected based on the skeleton model and the character region designation code. For example, the character designation information for an adult / male / slim body with singer A as the head is #AMTHA according to (Table 2). Here, # is a prefix indicating that the identification information is character designation information.

[0065]

[Table 3]

Table 3 shows an example of a skeleton model of each character and an example in which the posture is changed according to the motion data. In Table 3, each character has 17 joints, and the posture can be changed by changing the angles of the joints.

Examples of skeleton models of various characters are shown in the vertical direction of the table. Adult male, b. Adult female, c. Child men and d. 1 shows a skeleton model of a dog in an anthropomorphic animal.

In the adult male skeleton model, the shoulder width is wider than that in the adult female skeleton model. Child male skeletal models have a smaller ratio of limb length to torso length than adult males or adult females. Animal and dog skeletal models have a long torso, short limbs, and a familiar shape.

An example is shown in which the attitude of the character is changed by the movement data in the horizontal direction of the table. A. Standing upright, b. Standing with both hands raised, c. She is standing with one hand,
You are moving your limbs with your joints.

In FIG. 7B, the character designation information includes the skeleton model designation code and the head designation code, the head designation code, the chest designation code, the waist designation code, the both arms designation code, and the both legs shown in (Table 2). It consists of a character part designation code consisting of a designation code, and selects a character. However, the character specification information includes information for specifying character data, but does not include the character data itself.

FIG. 7C shows the data structure of the motion data designation information. The motion data is obtained by dividing a series of motions of the character for each short time, and a long-time motion can be given to the character by combining the motion data in time series. Also, by changing the combination of the motion data, it is possible to make the character make various movements. The motion data designation information designates the motion data in time series.

The motion data designation information is performed by designating the motion data identification information, and includes a skeleton model designation code, a motion genre designation code, and a motion beat number designation code. (Table 4) shows the motion data identification information.

[0073]

[Table 4]

The motion data identification information includes a character skeleton model designation code (vertical axis in Table 4), a motion genre designation code (horizontal axis in Table 4), and a motion beat number designation code (horizontal axis in Table 4). .

The motion data is specified by the motion of each joint of the skeletal model.
It has one joint and one center point, and the center point specifies the movement of the entire body of the skeletal model. Therefore, even if the movement looks the same, for example, walking or running, if the length of the limb is different, the movement of the joint is different, so that the movement data is different, and the skeleton model designation code is different.

The motion genre designating code is a code for designating the type of motion, and includes a dance motion, a conversation motion,
A different motion genre designation code is given for each type of motion that moves the character, such as a singing motion, a walking motion, and a running motion.

The movement beat number designation code is a code effective for a movement matching music or voice. In a movement genre (for example, dance) accompanied by music, each movement data indicates how many beats a character has. It indicates whether or not it has moved at the number of beats. For example, the motion data identification information “AMTD2” in (Table 4) indicates that the adult / male / slim skeletal model moves in the motion genre designating code of dance and the number of beats specifying code “2”, that is, two beats. While the character moves, the motion data indicates that the motion is just right when two beats of dance music are being played.

The dance motion data can be created in advance by, for example, capturing actual human motion data by motion capture.
In this case, the motion data is fetched while performing the dance music as a background sound, and the data is processed in a short time (for example, about several seconds) in the subsequent data processing. It is classified according to what you hit.

Further, the movement beat number designation code in the case of conversation indicates how many syllables are pronounced. For example, the movement beat number designation code "3" in the case of conversation is a movement in the case where three syllables are pronounced.

In the same manner, the movement beat number designation code is divided into walking, running, and the like. For example, the movement beat number designation code “2” in the case of walking is used for the right foot and the left foot once in the movement data (total). (2 times) indicates that the player has stepped on.

However, the motion beat number designation code is a code which is not designated when there is no classification of beat number other than music or conversation. In FIG. 7C, the motion designation information gives a series of motions to the character by designating the motion identification information in a time-series manner. The data structure includes a skeleton model designation code, a motion genre designation code,
It consists of a movement beat number designation code. However, as described above, depending on the movement, there is a movement that does not make sense because the movement beat number designation code is not provided.

The motion specifying information includes information for specifying the motion data, but does not include the motion data itself. As described above, FIG.
Is composed of character designation information, motion data designation information, etc., and does not include character data itself or motion data itself.

In FIG. 6, what is stored in the scenario database 35 on the server side is the scenario data 5.
It is one. What is stored in the character database 36 on the server side is the character data itself.
As shown in (Table 2), in the character data, identification information is given and stored for each skeleton model, each character part, and each part shape. What is stored in the server-side motion database 37 is the motion data itself, as shown in Table 4, for each skeleton model of the character, for each genre of motion, and for each beat of motion (however, In some cases, the number of beats of the movement is not specified and an identification code relating to the number of beats is not given.)

In FIG. 6, the server 31 has a scenario data selecting means 38, a scenario data generating means 39 and an interface 40. The scenario data selecting means 38 selects the scenario data 51 stored in the scenario database 35 on the server side, and transfers it to the terminal 32 via the network 33 through the interface 40.

The scenario data generating means 39
When the scenario data request signal 52 and the identification information 53 are received from the server, new scenario data is generated based on the identification information 53.

FIGS. 8 and 9 show flowcharts of the server 31. FIG. First, in FIG. 8, when the transfer of the scenario data 51 to the terminal 32 is to be started (step 711), in (step 712), the scenario data selecting means 38 transmits the scenario database 3 on the server side.
The scenario data 51 is selected from 5 and transferred to the terminal 32 via the network 33 by the interface 40.

Next (step 713), the terminal 32
To check if a scenario data request signal 52 has been received from the server.
If not, it is checked (step 718) whether the scenario data request signal 52 is received from the terminal 32. If not (step 713)
Then, the process of (Step 713) and (Step 718) is repeated.
