  The processing unit 100 includes a communication control unit 108, an object space setting unit 110, a movement / motion processing unit 112, a virtual camera control unit 114, a drawing unit 120, and a sound generation unit 130. Note that some of these may be omitted.

  The communication control unit 108 performs a process of transmitting the setting information transmission request to the server 30 via the communication unit 196 and receiving the setting information transmitted from the server 30 via the communication unit 196. Further, the communication control unit 108 transmits the operation data input by the player through the operation unit 160 to the other game device 10 via the communication unit 196 and the operation data transmitted from the other game device 10. The process to receive via is performed.

  The object space setting unit 110 is an object composed of various objects (polygons, free-form surfaces, subdivision surfaces, etc.) representing display objects such as characters, buildings, stadiums, cars, trees, pillars, walls, and maps (terrain). ) And setting the light source in the object space. For example, the position and rotation angle (synonymous with the direction and direction of the object in the world coordinate system, for example, rotation when rotating clockwise when viewed from the positive direction of each axis of the X, Y, and Z axes in the world coordinate system. The angle is determined, and the object is arranged at the position (X, Y, Z) at the rotation angle (rotation angle about the X, Y, Z axis).

  In particular, the object space setting unit 110 of the present embodiment sets the base object and the part object in the object space as constituent elements of the character based on the setting information stored in the setting information storage unit 177.

  The movement / motion processing unit 112 performs a movement / motion calculation (movement / motion simulation) of an object (character, moving object, etc.). That is, operation data input by the player through the operation unit 160, operation data transmitted from another game apparatus 10, a program (movement / motion algorithm), various data (motion data), a physical law (physical simulation information), etc. Based on the above, a process of moving the object in the object space or moving the object (motion, animation) is performed. Specifically, object movement information (position, rotation angle, speed, or acceleration) and motion information (position or rotation angle of each part that constitutes the object) are sequentially transmitted every frame (1/60 seconds). Perform the required simulation process. A frame is a unit of time for performing object movement / motion processing (simulation processing) and image generation processing.

  Further, the movement / motion processing unit 112 (motion processing unit) may perform a process of operating the part object based on physical simulation information set in the part object.

  The virtual camera control unit 114 performs a virtual camera (viewpoint) control process for generating an image viewed from a given (arbitrary) viewpoint in the object space. Specifically, the position (X, Y, Z) or rotation angle of the virtual camera in the world coordinate system (for example, the rotation angle when rotating in the clockwise direction when viewed from the positive direction of each axis of the X, Y, and Z axes). Process to control. In short, processing for controlling the viewpoint position, the line-of-sight direction, and the angle of view is performed. For example, the virtual camera control unit 114 may control the virtual camera to follow the movement of the moving object. That is, in order to shoot an object (for example, a character or a moving object) from behind using a virtual camera, the virtual camera position or rotation angle (virtual camera orientation) is set so that the virtual camera follows changes in the position or rotation of the object. ) To control. In this case, the virtual camera can be controlled based on information such as the position, rotation angle, or speed of the object obtained by the movement / motion processing unit 112. Alternatively, the virtual camera may be controlled to rotate at a predetermined rotation angle or to move along a predetermined movement path. In this case, the virtual camera is controlled based on the virtual camera data for specifying the position (movement path) or rotation angle of the virtual camera. When there are a plurality of virtual cameras (viewpoints), the above control process is performed for each virtual camera.

  The drawing unit 120 performs drawing processing based on the results of various processing (game processing) performed by the processing unit 100, and thereby images (character images in which the base object and the part object are set as components). Is generated and output to the display unit 190. When generating a so-called three-dimensional game image, first, object data (model data) including vertex data (vertex position coordinates, texture coordinates, color data, normal vector, α value, etc.) of each vertex of the object (model) ) Is input, and vertex processing (shading by a vertex shader) is performed based on the vertex data included in the input object data. When performing the vertex processing, vertex generation processing (tessellation, curved surface division, polygon division) for re-dividing the polygon may be performed as necessary.

  In the vertex processing, in accordance with the vertex processing program (vertex shader program, first shader program), vertex movement processing, coordinate transformation, for example, world coordinate transformation, visual field transformation (camera coordinate transformation), clipping processing, projective transformation (viewpoint conversion) Geometry processing such as perspective conversion, projection conversion), viewport conversion (screen coordinate conversion), and light source calculation is performed, and based on the processing results, the vertex data given to the vertex group that composes the object is changed. (Update, adjust). Object data after the geometry processing (position coordinates of object vertices, texture coordinates, color data (luminance data), normal vector, α value, etc.) is stored in the object data storage unit 176.

  Then, rasterization (scan conversion) is performed based on the vertex data after the vertex processing, and the surface of the polygon (primitive) is associated with the pixel. Subsequent to rasterization, pixel processing (shading or fragment processing by a pixel shader) for drawing pixels (fragments forming a display screen) constituting an image is performed. In pixel processing, according to a pixel processing program (pixel shader program, second shader program), various processes such as texture reading (texture mapping), color data setting / change, translucent composition, anti-aliasing, etc. are performed, and an image is processed. The final drawing color of the constituent pixels is determined, and the drawing color of the perspective-transformed object is output (drawn) to the drawing buffer 174 (a buffer capable of storing image information in units of pixels; VRAM, rendering target). That is, in pixel processing, per-pixel processing for setting or changing image information (color, normal, luminance, α value, etc.) in units of pixels is performed. Thereby, an image that can be seen from the virtual camera (given viewpoint) in the object space is generated. Note that when there are a plurality of virtual cameras (viewpoints), an image can be generated so that an image seen from each virtual camera can be displayed as a divided image on one screen.

  The vertex processing and pixel processing are realized by hardware that enables polygon (primitive) drawing processing to be programmed by a shader program written in a shading language, so-called programmable shaders (vertex shaders and pixel shaders). Programmable shaders can be programmed with vertex-level processing and pixel-level processing, so that the degree of freedom of drawing processing is high, and expressive power is greatly improved compared to conventional hardware-based fixed drawing processing. Can do.

  The drawing unit 120 performs texture mapping, hidden surface removal processing, α blending, and the like when drawing the object.

  Texture mapping is a process for mapping a texture (texel value) stored in the texture storage unit 178 of the storage unit 170 to an object. Specifically, the texture (surface properties such as color (RGB) and α value) is read from the texture storage unit 178 of the storage unit 170 using the texture coordinates set (applied) to the vertices and pixels of the object. Then, a texture that is a two-dimensional image is mapped to an object. In this case, processing for associating pixels with texels, bilinear interpolation or the like is performed as texel interpolation.

  As the hidden surface removal processing, hidden surface removal processing by a Z buffer method (depth comparison method, Z test) using a Z buffer 179 (depth buffer) in which a Z value (depth information) of a drawing pixel is stored may be performed. it can. That is, when drawing pixels corresponding to the primitive of the object are drawn, the Z value stored in the Z buffer 179 is referred to. Then, the Z value of the referenced Z buffer 179 is compared with the Z value at the drawing pixel of the primitive, and the Z value at the drawing pixel is the front side when viewed from the virtual camera (for example, a small Z value). If it is, the drawing process of the drawing pixel is performed and the Z value of the Z buffer 179 is updated to a new Z value.

  α blending (α synthesis) is a translucent synthesis process (usually α blending, addition α blending, subtraction α blending, or the like) based on an α value (A value).

  The α value is information that can be stored in association with each pixel (texel, dot), for example, plus alpha information other than color information. The α value can be used as mask information, translucency (equivalent to transparency and opacity), bump information, and the like.

  The drawing unit 120 may draw the base object and the part object based on color information selected by the player (color information stored in the setting information stored in the setting information storage unit 177). That is, the colors of the drawing pixels of the primitives constituting the base object and the part object may be set based on the color information selected by the player.

  Further, the drawing unit 120 refers to the setting information stored in the setting information storage unit 177, and in accordance with the combination of the base object and the part object associated with the character, the shape, size, The base object and the part object may be drawn by changing at least one of color and motion.

  The sound generation unit 130 performs sound processing based on the results of various processes performed by the processing unit 100, generates game sounds such as BGM, sound effects, or sounds, and outputs the game sounds to the sound output unit 192.

  Note that the image generation system of the present embodiment may be a system dedicated to the single player mode in which only one player can play, or may be a system having a multiplayer mode in which a plurality of players can play. Further, when a plurality of players play, game images and game sounds to be provided to the plurality of players may be generated using one terminal, or connected via a network (transmission line, communication line) or the like. Alternatively, it may be generated by distributed processing using a plurality of terminals (game machine, mobile phone).

2. Next, the method of this embodiment will be described with reference to the drawings.

2-1. Outline The game of the present embodiment is an online fighting game, and each player can customize the hairstyle of his / her character appearing in the fighting game using the information processing apparatus 40 such as a mobile phone.

The player can select the character type, clothes, hairstyle, and the like from a plurality of options on the customization screen. In particular, for a hairstyle, one base object and at least one part object can be selected from a plurality of base objects serving as a base of the hairstyle and a plurality of part objects that can be attached to the base object. The player can also select a hairstyle color (color information) on the customization screen. The player also has an IC card for storing the player ID, and inputs the player ID (card number) printed on the surface of the IC card on the customization screen.

Are stored in association with the player ID 210 input by the player on the customization screen.

  When the player sets the IC card in the card reader provided in the game apparatus 10 at the start of the game, the game apparatus 10 reads the player ID from the IC card and transmits the read player ID to the server 30. When the server 30 receives the player ID from the game apparatus 10, the server 30 transmits setting information corresponding to the player ID to the game apparatus 10. In addition, the server 30 transmits setting information corresponding to the player ID of another player who is an opponent of the player to the game apparatus 10. Then, the game apparatus 10 sets the base object and the part object specified in the setting information 200 transmitted from the server 30 as the constituent elements of the character specified in the setting information. The model data of the character (character object), base object, and part object is stored in advance in the object data storage unit 176 of the game apparatus 10.

FIG. 5A shows a case where “Ponytail A” is selected as the base object BO, and “Back hair A”, “Right bangs A”, and “Left bangs A” are selected as the part objects PO to be attached to “Ponytail A”. FIG. 5B shows an example of customizing the hairstyle of the character when “back hair B” and “front hair B” are selected as the part object PO attached to “ponytail A”. .

  As shown in FIGS. 5 (A) and 5 (B), “Ponytail A” is a base object BO to which a part object PO representing one bundle of back hair is attached at one location on the back of the head. The hair is gathered toward the attachment position (one knot) of the back hair so that a natural expression is obtained when the part object PO to be represented is attached. Further, at least one part object PO representing the bangs can be attached to the “ponytail base A”.

  FIG. 6 is a diagram for explaining the base objects “ponytail B” and “ponytail C” of the present embodiment. As shown in FIG. 6, “Ponytail B” and “Ponytail C” are base objects BO to which a part object PO representing one bundle of back hair is attached at one position on the back of the head, like “Ponytail A”. The hair is gathered toward the attachment position (one knot) of “Ponytail B”, but the attachment position (knot) of the back hair is provided above “Ponytail A” and “Ponytail C”. The knot is provided below “Ponytail A”.

  FIG. 8 is a diagram for explaining the base object “twin tail B” of the present embodiment. As shown in FIG. 8, “twin tail B” is a base object BO to which two part hairs representing the back hair are attached at two locations on the back of the head, similar to “twin tail A”. The hair is gathered toward (two knots), but two attachment positions (two knots) of the back hair are provided below “Twin tail A”.

  FIG. 9A and FIG. 9B are diagrams for explaining the base object “all back” of the present embodiment. FIG. 9A shows an example of customizing the character's hairstyle when “all back” is selected as the base object BO and “back hair G” is selected as the part object PO attached to “all back”. (B) shows an example of customizing the hairstyle of the character when “back hair H” is selected as the part object PO attached to “all back”.

By expressing this hairstyle, it is possible to perform various expressions on the character's hairstyle while suppressing the data amount of the object, compared to the case where a plurality of objects representing the entire hairstyle are stored.

  In addition, according to the present embodiment, by preparing a plurality of base objects having different aspects according to the position and number (parts and number of knots) to which the part object representing the back hair is attached, the part object representing the back hair is attached to the base object. When attached, it is possible to prevent an unnatural expression.

2-3. Creation of Base Object and Part Object In this embodiment, the object data storage unit 176 stores a plurality of types of base objects and a plurality of types of part objects that can be attached to each base object for each character type. This is because the shape of the head and the height of the head (head position) are different for each character. Therefore, depending on the character to which the base object and the part object are attached, the shape of the base object and the attachment position of the base object and the part object ( This is because it is necessary to change the position of the character in the local coordinate system.

  In this embodiment, a base object and a part object corresponding to each of a plurality of other characters are created and stored in advance from a base object and a part object corresponding to one character.

  10A and 10B are diagrams for explaining the creation of the base object and the part object.

  As shown in FIGS. 10A and 10B, a bone BB (base bone) is set in the base object BO, and a bone VB (virtual part bone) and a bone PB (part bone) are set in the part object PO. Is set. The base object BO and the virtual part bone VB are parent-child related to the base bone BB, the part bone PB is constrained to the virtual part bone PB, and the part object PO is skin-bound to the part bone PB. The part bone PB is a skeleton composed of a plurality of bones and joints, and is set to operate the part object PO.

  For example, when the base object BO for the character B is created from the base object BO for the character A, the character B is input by inputting a scale value to the base bone BB set to the base object BO for the character A. The base object BO for the character A is deformed according to the skeleton (head shape) of the character B to create the base object BO for the character B. The scale value can be input for each of the three axial directions of the base bone BB.

  Here, the scale value input to the base bone BB is reflected in the virtual part bone VB, and the position and size of the virtual part bone VB change. Since the part bone PB is constrained to the virtual part bone VB, the size does not change, only the position changes, and the part object PO similarly changes only the position.

  That is, in the state where the base object BO for the character A and the part object PO are associated with each other as shown in FIG. 10B, the scale value is input to the base bone BB of the base object BO. The position (attachment position) of the part object PO for the character A is changed in accordance with the deformation of the base object BO to create the part object PO for the character B.

  As described above, according to the present embodiment, the base object deformed according to the skeleton of another character from the base object and the part object of one character, and the attachment position is changed according to the deformation of the base object. Part objects can be easily created.

2-4. Part Object Operation FIG. 11 is a diagram for explaining the operation of the part object of the present embodiment.

  As shown in FIG. 11, in the present embodiment, the bone PB (part bone) set in the part object PO is controlled based on physical simulation information such as the weight and inertia force of the part object PO. Performs processing to move (motion).

  Further, in the present embodiment, in order to prevent the part object PO from sinking into the character's body, a hit object HO having a shape along the character's skeleton is set in the part object PO as physical simulation information, and the part object The operation of the part object PO is controlled so that the PO is played by the hit object HO.

  Here, since the skeleton of the character is different for each character, as shown in FIG. 11, a hit object HO that matches the skeleton of the character A is set for the part object PO for the character A, and the parts for the character B are set. A hit object HO that matches the skeleton of the character B is set for the object PO. In this way, the motion of the part object PO can be controlled according to the skeleton of the character.

2-5. Drawing According to Combination of Base Object and Part Object FIGS. 12A and 12B are diagrams for explaining drawing according to a combination of a base object and a part object.

  In the present embodiment, when the combination of the base object and the part object associated with the character becomes a predetermined combination, at least one of the shape, size, color, and motion of the part object is changed. Specifically, shape information, scale information, color information, motion data, and the like corresponding to a predetermined combination of the base object and the part object are stored as table data, and the shape of the part object by referring to the table data, Change the size, color, and motion.

  For example, as shown in FIG. 12A, when “all back” is selected as the base object BO and “bangs C” is selected as the part object PO, the shape of the part object PO attached to the base object BO, etc. Draw without changing. On the other hand, as shown in FIG. 12B, when “back hair G” is selected in addition to “bangs C” as the part object PO, the shape of the part object PO of “bangs C” attached to the base object BO The image is drawn by performing a process of enlarging in the front-rear direction. At this time, the part object PO of “bangs C” or “back hair G” may be operated in a predetermined motion, or the part objects PO of “bangs C” and “back hair G” and the base object BO are set in advance. It is also possible to draw with the color (color information set in the table data).

  As described above, according to the present embodiment, various expressions of hairstyles can be performed by combining the base object and the part object.

3. Processing Next, an example of processing of the game apparatus 10 of the present embodiment will be described with reference to the flowchart of FIG.

  First, the communication control unit 108 transmits the player ID of its own player read from the IC card set in the card reader to the server 30 (step S10). Next, the communication control unit 108 receives the setting information 200 transmitted from the server 30 and stores it in the setting information storage unit 177 (step S12).

  Next, based on the setting information 200, the object space setting unit 110 selects the base object and part object for the character selected by the player of the own device and selected by the player of the own device. Then, it is set as a constituent element of the character selected by the player of the own device (step S14).

  Next, the object space setting unit 110, based on the setting information 200, is a base object and a part object selected by the player of the other machine that is the opponent, and is a base for the character selected by the player of the other machine. The object and the part object are set as constituent elements of the character selected by the player of the other machine (step S16).

  Next, the object space setting unit 110 places the player's player character and the player's player character in the object space (step S18).

  Next, the movement / motion calculation unit 112 performs the movement / motion calculation of the player's player character based on the operation data from the operation unit 160, and based on the operation data transmitted from the other game apparatus 10, The player's character movement / motion calculation is performed (step S20).

  Next, the rendering unit 120 generates an image that is an image of the object space viewed from the virtual camera and includes the player's player character and the player's player character (step S22). At this time, the drawing unit 120 refers to the setting information 200 and draws the base object and the part object of each character based on the color information 250 corresponding to each character.

  Next, the processing unit 100 determines whether or not to continue the process (step S24), and proceeds to the process of step 20 when the process is continued.
