BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a video game character editing program, a recording medium therefor, and a video game device according to the present invention will be described below. In the following, a player uses the video game device having the configuration shown in FIG. 17 to play the game by operating the controller 120, and the game program, image data, and sound data are read from the DVD-ROM 130. RAM10
It is assumed that it is recorded in 3. It is also assumed that the player has selected one character from a plurality of characters.

FIG. 1 is a flowchart showing the processing performed by the CPU 101. In step 101, GPU
The RAM 103 stores text data (see (a) of FIG. 2) corresponding to the name of the part in which the parts can be set for the character selected by the player.
Read out and displayed on the video display device 150. FIG. 3 is an example of a screen displayed on the image display device 150. A CG image of a character is displayed on the right side, a list of parts in which parts can be set for the character is displayed on the left side, and a selection from the player is accepted. It is a state screen.

In step 102, the controller 1
20 receives a signal from the I / F unit 111, and the player operates the button of the controller 120.
It is determined whether or not the part is selected, and when it is determined that the part is selected, the process proceeds to step 103. The state of accepting the selection by the operation of the controller 120 is maintained until it is determined that the selection is made.

In step 103, step 101
Similarly, a command is issued to the GPU 104 to read the text data (see (a) of FIG. 2) corresponding to the part type that can be set for the selected region from the RAM 103 and display it on the video display device 150. FIG. 4 shows an example of a screen presented to the video display device 150 after “upper body” is selected in FIG. On the left side of this screen,
A list of configurable part types is displayed.

In step 104, step 102
Similarly, it is determined whether the button of the controller 120 is operated to select the part type.

In step 105, a command is issued to the GPU 104, and the text data (see FIG. 2B) of the part name corresponding to the part type selected in step 104 is read out from the RAM 103, and the video display device is displayed. Display in 150 as a list. FIG. 5 shows FIG.
3 shows an example of a screen displayed on the video display device 150 after the player selects T-shirt as the type of part. On the left side of this screen, T-shirt names are displayed as a list as settable part names.

In step 106, when the player operates the button of the controller 120 to temporarily select the T-shirt name, the CPU 101 issues a command to the GPU 104, and the CG corresponding to the temporarily selected T-shirt name.
The data is read from the RAM 103 and the character C
The read CG data is added to the G data, and the obtained CG data is used to generate an image of the character.
In FIG. 5, data corresponding to the part code = 1003 (see (b) in FIG. 2) corresponding to the fourth T-shirt from the top that is provisionally selected from the T-shirt names on the left side of the screen is used. An image of a character wearing a designated T-shirt is displayed on the right side of the screen. The specific structure and data processing of CG data will be described later.

In step 107, step 104
Similarly, the button of the controller 120 is operated to determine whether or not a specific T-shirt name is selected. If it is determined that it has been selected, the process proceeds to step 108. The state of accepting the selection by the operation of the controller 120 is maintained until it is determined that the selection is made.

In step 108, a command is issued to the GPU 104 to select the selected part name (T-shirt name).
Display the screen to change the parameter for. Figure 6
Shows an example of a screen in which parameters that can be changed for the T-shirt name selected in step 107 are displayed on the left side. For example, the T-shirt parameters are
Sleeve length, transparency, color (hue, saturation, lightness).
On the left side of FIG. 6, slide bars 600 to 604 are displayed for each parameter so that the set values of these parameters can be easily grasped visually. As described below,
After designating the parameter to be changed by the controller 120, by operating the controller 120,
A CG image in which the lengths of the slide bars 600 to 604 and the corresponding parts of the character are changed is displayed.

In step 109, the controller 1
A change in the sleeve length is accepted by the operation of 20. Figure 6
In, the uppermost slide bar 600 represents the state of the sleeve length. Hereinafter, an example of the CG data structure will be shown to specifically describe the parameter changing process regarding the T-shirt.

FIG. 7 shows an example of CG data of a character. FIG. 7 is an example of CG data when the object surface is represented by triangular polygons. The CG data is the number and X assigned to each vertex of the triangular polygon,
A "vertex table" recorded by correlating Y and Z coordinates, a color code, color data, a "color table" recorded by correlating transparency, texture code, texture image data file name, color data (rotation angle of color coordinate axis ), A "texture table" recorded in association with transparency, and a "polygon table" recorded in association with a vertex number of a polygon and a pattern code that is color or pattern information for the polygon. The pattern code is a code corresponding to the color code or the texture code.
In the polygon table (d) of FIG. 7, the pattern code = 001 is specified for all polygons, and the character is displayed in a single color.

An actual character is composed of many objects, but here, for the sake of simplicity, it is composed of objects of the head, right arm, left arm, chest, upper abdomen, lower abdomen, right leg, and left leg. Assume Also, it is necessary to set bones for each object and set connections between the bones so that the objects do not become disjointed when the character is deformed, but this information is omitted here.

FIG. 8 is a table recording information about parts. FIG. 8A is a "part / object correspondence table" that represents the correspondence between parts types and objects. When a parts type is designated by this table, which object polygon is to be processed is determined. It is determined. FIG. 8B is a “parts table” in which an object having a changeable parameter is associated with the parameter and a part code is attached to the object and recorded. In the (b) parts table of FIG. 8, T
With respect to the shirt, a colored region is set for the right arm and the left arm as a parameter for changing the sleeve length. The colored area indicates the colored area of the object, for example, the length direction (bone direction) of the object.
Can be expressed as a ratio of For example, colored area =
In the case of 0.8, 80% of the length of the entire arm is colored, and the remaining 20% is not colored. Further, in the case of a T-shirt, since the lengths of the chest and the upper abdomen are not changed, no related data is recorded in the parts table of FIG. 8B.

The data shown in FIGS. 7 and 8 are the data recorded in the RAM 103 by reading the data previously recorded in the DVD-ROM.

FIG. 9 shows that the specific T
After the shirt is selected, the CG data in a state in which the information of the part, that is, the T-shirt is added to the CG data shown in FIG. 7 is shown. The actual object is composed of more polygons, but is limited to a small number here. The column of "character basic data" in FIG. 9 is the same polygon table as in FIG. 7D, and the column of "part designation data" is data added by the player selecting a specific T-shirt. Is. From the parts / object correspondence table of FIG. 8A, the right arm, the left arm, the chest, and the upper abdomen are determined as objects to be processed in the case of a T-shirt.

The layer number of the part designation data is a number given to each added part and represents the order of overlapping of the parts. As will be described later, 2 from 3D CG data
When generating the dimensional CG image, the layer number is taken into consideration. The pattern code is data that specifies the color or texture of the part, and corresponds to the color code or texture code recorded in the color table or texture table. A vertex number is set in each cell of the vertices 1 to 3 of the basic data of the character, but it is omitted here. The "-" symbol in the part designation data indicates that the cell has no data.

In FIG. 9, the layer number = 1 and the code number = 00 as the initial state before the parameter of the part is changed.
3 is set to the polygons corresponding to the right arm, the left arm, the chest, and the upper abdomen. The two-dimensional image generated using this three-dimensional CG data is the image shown on the right side of FIG.

FIG. 10 shows a state in which the part designation data is changed by operating the controller 120. FIG. 10A shows an initial state in which the pattern code = 003 is set to all polygons of the right arm and the left arm as in FIG.

Here, the left arm and the polygons forming the surface of the left arm (numbers = 100 to 105 and 200 to 205)
Assume that the cuffs are numbered from the cuffs to the sides. That is, by giving the relative position information of the polygons forming the sleeve to the size of the polygon number and adding or deleting the pattern code in the order of the polygon number, an image in which the sleeve length of the T-shirt is changed is obtained. First, the player operates the controller 120 to decrease the value of the colored area from the value shown in FIG. 8B. The number of uncolored polygons is calculated from the reduced value and the number of polygons of the entire arm, and the pattern codes of the same number of cells are deleted. That is, for the right arm, the cell code number is deleted from the polygon number = 100 in the direction in which the cell number gradually increases, and for the left arm, the cell code number is deleted in the direction from the polygon number = 200 to the cell number. .
In FIG. 10B, polygon numbers = 100, 101, 2
The pattern codes 00 and 201 are deleted. By generating a character image based on the CG data in FIG. 10B, an image of a character wearing a T-shirt having a shorter sleeve length than the image shown in FIG. 6 is generated. Also, the corresponding slide bar 600
The length of is also displayed short.

In step 110, a change in transparency of the part is accepted. Controller 12 by player
The operation of 0 is accepted, and the transparency in the color table recorded in the RAM 103 is changed by a predetermined value. That is, in the case of FIG. 10, the transparency of code = 003 in the color table of FIG. 7B is changed. When a CG image is generated from CG data, this color table is used, so that the transparency of the polygon to which code = 003 is changed. Corresponding slide bar 6
The length of 01 is also changed.

In step 111, step 110
Similarly, the color data is changed. That is, in the case of FIG. 10, code = 0 in the color table of FIG. 7B.
One parameter specified by the player among the hue, saturation, and brightness of 03 is accepted by the operation of the controller 120 and changed by a predetermined value. Slide bar 602-60
The length of the corresponding slide bar of 4 is also changed.

When a part having a texture mapped on the surface is designated in step 107, the color data (rotation angle) of the texture table shown in FIG. 7C is changed by the player operating the controller 120 when changing the color. ) Is changed. That is, the color of the displayed texture is changed by rotating the coordinate axis of the color space that interprets the pixel value of the two-dimensional image data used as the texture.

In step 112, after the player confirms the image of the part (T-shirt) on the image displayed on the right side of the screen, the controller 120 is operated to determine the parameter, and the code at that point is = 003. A new color code that does not overlap with the color code already recorded in the color table is added to the transparency and color data of
Record in the color table 103. Also, code = 003
DVD-RO to restore the original data to the original data
Corresponding data is read from M130, RAM103
Record in the color table of. Figure 11 shows the new color code =
Reference numeral 100 indicates a state in which the parameters set by the player are recorded in the color table. Further, as shown in (c) of FIG. 10, the pattern code of the part designation data is code = 1, which is newly determined from code = 003.
Change to 00. Then, the determined layer number = 1, the color code = 100, and the parameter of the changed length are associated and recorded in the RAM 103 as a layer table (see (c) of FIG. 13). For the parts to which the texture is mapped, the texture table is used instead of the color table to perform similar processing.

In step 113, the above process is repeated until it is determined that the process is completed.

FIG. 12 shows CG data when the above processing is repeated and two T-shirts and two tights are set for the same character. The code of layer number = 1, the code of layer number = 3, the code of layer number = 3, and the code of layer number = 4 = 102 correspond to the code = 100, 101, and 102 in the color table of FIG. And the code = 300 of the layer number = 2 is (b) in FIG.
Corresponds to code = 300 in the texture table of. The layer information corresponding to these is shown in FIG.
As shown in the layer table of (c). Here, the related information is information about the length, and is data of a colored region corresponding to the length of the sleeve when the part is a T-shirt, for example.

When the character in which the parts are designated is used in the game, the layer number indicating the overlapping of the parts is determined from the CG data (see FIG. 12) constituted by the basic data of the character and the parts designation data. Considering the above, a normal format polygon table is created and the data is used. For the data in FIG. 12, the polygon table shown in FIG. 14 is generated. In FIG. 12, for polygon numbers = 102, 103, 202, 203, since only the layer having the layer number = 1 is set, the corresponding pattern code in the basic data of the character is changed from “001” to “100”. has been changed.
Also, polygon number = 104, 105, 204, 205
With regard to (2), since two layers of layer numbers = 1 and 2 are set, the corresponding pattern code in the basic data of the character is changed from “001” to the pattern code “300” of the uppermost layer. The pattern code is similarly changed from "001" for the portion where the two tights are designated.

By recording the information of the parts specified by the player in the external memory 140 before ending the game, the information of the parts is read from the external memory 140 when the power of the game apparatus main body 100 is turned on next time. It is possible to play a game using a character that has been issued and for which parts have been set previously. For example, the character name, the layer table (see FIG. 13C), and the color table or texture table data (FIG. 13) corresponding to the pattern code used in the layer table.
(See (a) and (b)) of the external memory 14
By recording this data on the DVD-
CG data of the character recorded in the ROM (see FIG. 7).
It is possible to create CG data (see FIG. 12) of a character wearing the set parts, based on the information about the parts (see FIG. 8).

On the basis of the layer table created in step 112, a state in which a plurality of parts are set for the character is displayed on the video display device,
It is possible to replace, duplicate, and delete layers. FIG. 15 is an image corresponding to the layer table of FIG.

On the left side of FIG. 15, layer numbers and part names are displayed in layers so that the player can easily understand the overlapping state of the parts. The layer number is (c) in FIG.
Corresponding to the layer number of the layer table of FIG. 2, the part name is obtained by using the part code of the layer table of FIG. 13C to obtain the corresponding part name in the table of FIG. 2B. indicate.

When changing the overlapping state of parts,
The player operates the controller 120 to select a specific layer displayed on the left side of FIG. 15 as a movement target, and operates an arrow button of the controller 120 to move the layer to a desired layer. After being determined by the operation of the controller 120, the layer number in the layer table of FIG. 13C is rewritten. For example, the second layer (T-shirt 002) in the layer list of FIG.
00), the corresponding layer numbers = 1 and 2 in FIG. 13C are exchanged. Further, when the parts are replaced by the above processing, that is, when the layer number of the layer table is changed, the corresponding layer number of the part designation data (see FIG. 12) in the CG data of the character is changed.

When the same part is duplicated and created, the process shown in FIG.
In order to prevent the layer numbers from overlapping with the same data (part code, pattern code, related information) of the layer table of FIG. 13C corresponding to the layer selected from the layer list on the left side of FIG. 13 (c)
1 than the maximum layer number existing in the layer table of
A large layer number is assigned and additionally recorded in the layer table of FIG. At the same time, the column data in which the new layer number and the pattern code are recorded is added to the part designation data (see FIG. 12) in the CG data of the character.

To delete a layer, the data (part code, pattern code, related information) in the layer table of FIG. 13C corresponding to the layer selected from the layer list on the left side of FIG. 15 is deleted. At the same time, decrement all layer numbers greater than the deleted layer number in the layer table by one. Further, the column data in which the corresponding layer number and pattern code of the part designation data (see FIG. 12) in the CG data of the character are recorded is deleted, and all the layer numbers larger than the deleted layer number are decreased by 1.

As described above, the player can specify a desired part for the character and edit the shape, color, transparency, and overlapping order of the specified part, and the character wearing the edited part can be used in the game. Can be used.

In the above description, in the explanation of the change of the length of the T-shirt in step 109, it is assumed that the polygon numbers are sequentially given from the cuffs to the sides, but as another means, the controller operation is performed. It is also possible to change the coordinate value of the cuff of the T-shirt. For example, the body axis direction of the character is the Z axis (the direction from the leg to the head is the positive direction), and the arm is Z parallel to the body axis.
Assuming that the sleeve is in the axial direction, the Z coordinate of the cuff when the sleeve is the longest is Z1, the Z coordinate of the cuff when the sleeve is the shortest is Z2, and the parameter changed by the operation of the controller is Z0. The Z coordinate Z (i) of the vertex of each polygon is Z1 <
By deleting the code of the polygon that satisfies Z (i) <Z0 <Z2, it is possible to generate a CG image in which the sleeve length is changed. In this case, the polygon number can be designated arbitrarily.

When texture mapping is used for parts, by further having a parameter β (i, j) indicating the effectiveness of each pixel (i, j) of the texture image to be mapped, It is possible to change the length of parts in pixel units. For example, as shown in FIG.
Β (i, j) in the area specified by the colored area (see the parts table in FIG. 8B) in the texture image data
= 0.0 and β (i, j) = 1.0 in the remaining area. When texture mapping is performed, β (i, j) =
In the situation where the pixels of the texture image of 0.0 are used, the mapping is performed using the pixel data of the texture image as it is, and the pixels of the texture image of β (i, j) = 1.0 are used. In, no mapping is done. Controller 1 by player
By changing the colored region in the range of 1.0 to 0.0 according to the operation of 20, and correspondingly moving the boundary position in β (i, j) shown in FIG. 16 pixel by pixel, It is possible to change the length of the area to be mapped on the part in pixel units.

In this case, for example, similar to the image file name of the texture image in the texture table shown in (c) of FIG. 7 or (b) of FIG. 13, β (i, j of a specific pattern is used as initial data. ) Is added to the file name.
Since the pattern of β (i, j) is changed by changing the colored area by the operation of the controller 120 by the player, after the change is determined, the changed β (i, j) is changed.
Save j) with a new file name. Along with this, a new texture code is added to the changed file name of β (i, j), the image file name of the texture image, the color data, and the transparency, and recorded in the texture table. Further, it is not necessary to change the pattern code shown in the change from (a) to (b) of FIG. 10, and the texture mapping considering β (i, j) using the data of (a) of FIG. Should be done.

In texture mapping,
Coordinate information that specifies the correspondence between the image data that becomes the texture and the area (polygon) to be mapped is necessary, but it is omitted for simplicity in the above description. For example, in FIG. 12, the layer number = 2 is the pattern code = 300, and the image file “200.dat” is the part to be mapped from the texture table of FIG. The coordinate information indicating the correspondence with the image data of the texture is specified for the polygon in the area to be mapped by the method.

Further, in the above description, the case where the triangular polygon is used has been described, but it is also possible to use a polygon having a quadrangle or more. Although the T-shirt has been described as a part, the CG data corresponding to the character wearing the part is created by creating the part data in the same manner as in FIG. 8 for the other clothes and the mask for the head. Is possible.

It is also possible to create part data representing a pattern smaller than the object, instead of a color or texture that uniformly covers a specific area on the surface of the object. In that case, similar to the texture table, table data in which the image file name of the pattern is recorded is created, and the position coordinate data of the representative point of the pattern with respect to the object is recorded as the coloring area data shown in FIG. It suffices to create, and by changing the position coordinates, the position of the pattern on the part can be changed. Here, the pattern smaller than the object includes characters, symbols, and the like, and also includes two-dimensional images such as eyes, eyebrows, mouth, whiskers, and scars.

Further, the parts are defined as the correspondence with the objects used in the modeling of the character, but it is also possible to directly define the correspondence with the plurality of polygons.

It is also possible to give a layer relationship to the three-dimensional parts. In that case, a part code is given to each part, and the same data as the three-dimensional CG data of the character shown in FIGS. 7A to 7D is set in advance. As the part designation data shown in FIGS. 9 and 12, instead of the pattern code,
By setting the part code, it is possible to freely specify the part for the character as in the above description. In that case, in the generation of CG data (see FIG. 14) in the case of playing a game using a character in which parts are set, it is added to the processing relating to the two-dimensional part to determine the overlap between the character object and the part object. Then, it is necessary to perform processing for leaving only the polygons at the highest level.

Characters are not limited to humans, but animals,
It is also possible to target plants, automobiles, airplanes, motorcycles, etc., and the recording medium of the game is not limited to DVD-ROM, but portable recording medium such as CD-ROM, semiconductor memory can also be used. is there.
