  The features of the present invention will become more apparent from the embodiments of the invention described below with reference to the drawings.

  FIG. 1 is a block diagram showing an example of an information processing apparatus to which the present invention is applied.

  In FIG. 1, the information processing apparatus has a program data storage device or a recording medium (including an optical disc and an optical disc drive) 1 in which programs and data (including video / music data) are stored.

  Further, in the information processing apparatus, the CPU 2 performs program execution, overall system control, coordinate calculation for image display, and the like. The system memory 3 stores programs and data necessary for the CPU 2 to perform processing.

  The boot (BOOT) ROM 20 stores programs and data necessary for starting the information processing apparatus. Further, the bus arbiter 40 controls the flow of program data with each block of the information processing apparatus and with external devices. The rendering processor 41 reproduces video (MOVIE) data read from the program data storage device or the recording medium 1, and generates an image for image display according to the player's operation or game progress.

  Graphic data and the like necessary for the rendering processor 41 to generate an image are stored in the graphic memory 5. The sound data read out from the program data storage device or the recording medium 1 and the generation of sound effects and sounds according to the player's operations and game progress are performed by the sound processor 7 to generate sound effects and sounds. Sound data necessary for this is stored in the sound memory 70.

  The bus arbiter 40 is connected to a modem 9 that communicates with another information processing apparatus or a network server through a telephone line. The modem 9 connected to this information processing apparatus uses a telephone line. However, a TA (terminal adapter) that uses a telephone line, a cable modem that uses a cable TV line, a cellular phone, and a PHS are also available. It is also possible to use a communication device that performs the used wireless communication means and optical fiber communication means.

  The bus arbiter 40 is connected to a controller 8 such as a control pad or a tablet that outputs information for controlling the information processing apparatus and externally connected devices to the information processing apparatus in accordance with the operation of the operator. Is connected to a backup memory 80 for storing and saving data such as parameters generated by the program.

  Furthermore, a speaker 71 that reproduces an audio signal output from the sound processor 7 and a display monitor 6 that displays an image signal output from the rendering processor 41 are connected to the information processing apparatus.

  In general, an information processing apparatus requests operation information from a controller 8 such as a tablet or a control pad every predetermined time, and the controller 8 operates an operation such as a trigger button or a touch panel when the request is made. The information is output to the information processing apparatus.

  Then, the information processing apparatus uses the operation information received from the controller 8 as a parameter when the CPU 2 executes the application program in the system memory 3, and reflects the operation of the operator to the rendering processor 41 and the sound processor 7. The processed image processing and sound processing are performed, and the image and sound are output to the display monitor 6 and the speaker 71.

  Note that the above information processing device may be a video game device, a personal computer, a workstation, a telephone or communication device having an image display function, or an image display device having a communication function or an information processing function. The application of is not disturbed.

  Assuming that the program executed in the information processing apparatus is a game program, the game program includes display object data as well as program data for controlling game execution.

  Here, in the application of the present invention, the display object is a character such as a person, an animal, a monster, or a robot, a vehicle such as an automobile, an airplane, a ship, or a bicycle, or a target displayed on a display device that can be operated by a player. It refers to all of (objects).

  The bus arbiter 40 and the rendering processor 41 can be integrally configured as a DSP (digital signal processor 4), and a coordinate conversion function for display object data having three-dimensional coordinates and a texture for polygons according to program data for controlling game execution. It has a function to execute data pasting.

  In the display object data coordinate conversion function, display object data having world coordinates is converted into three-dimensional viewpoint coordinates and then converted into two-dimensional coordinates.

  The display object data converted into two-dimensional coordinates and attached with the texture data is sent to the graphic memory 5, sequentially read out, converted into a video signal, and displayed as an image on the display monitor 6.

  Further, based on the data for controlling the game execution, in synchronization with the image display, the digital audio signal is processed by the sound processor 7 and converted into an analog audio signal, and is displayed as a sound on the speaker 71.

  Thus, in an information processing apparatus in which a game program is executed, the present invention has a display object generation program by a player as a part of the game program or as an individual program.

  When the display object generation program is included in a part of the battle game program as an embodiment, the display object generation program is controlled to be executed at an appropriate preset time point in the progress of the battle game program. It is desirable that this appropriate time point is executed prior to the stage for selecting a display object to be battled in the battle game program.

  FIG. 2 is a diagram showing an embodiment flow of a display object generation program according to the present invention.

  In FIG. 2, when the display object generation program is started, a skeleton selection menu screen is displayed on the display device 6 (processing step P1). Examples of this menu screen are shown in FIGS.

  On the menu screen, an area I for displaying a perspective skeleton model of a generated display object selected in the center and a plurality of display object selection buttons II are displayed around the area I.

  The player designates an arbitrary display object selection button II by moving and controlling the pointer III using the input device 8 including a keyboard and a mouse connected to the game apparatus shown in FIG. 1 (processing step P2).

  FIG. 3 is an example in which a humanoid display object is selected, and FIG. 4 is an example in which a dinosaur-type display object is selected. In both cases, a fluoroscopic skeleton model is displayed superimposed on a basic image corresponding to the selected display object. Is done. In the present invention, parameters can be set for each of a plurality of skeleton parts (parts) constituting the fluoroscopic skeleton model as will be described later.

  As shown in FIGS. 3 and 4, the fluoroscopic skeleton model of the selected display object is displayed, and when confirming this, the player positions the pointer III on the confirm button IV and confirms the input. In this way, when the skeleton model selection process (processing step P2) is completed, the process proceeds to the drawing mode (processing step P3).

  5 and 6 are diagrams showing image display in the drawing process of the humanoid display object and the dinosaur display object selected corresponding to FIGS. 3 and 4, respectively, in the drawing mode.

  As described above, the fluoroscopic skeleton model is displayed so as to be superimposed on the basic shape image as described above. With reference to the basic shape image, the outline of the display object is easily imaged and the pen pointer V is displayed on the screen by the input device 8. It is possible to move with. Therefore, the movement locus VI of the pen pointer V is sequentially displayed.

  As an embodiment of the present invention, the movement trajectory VI, that is, the contour trajectory is displayed superimposed on the displayed fluoroscopic skeleton model.

  At this time, since the contour setting process (processing step P4) is performed in the next step according to the present invention, even if the movement locus VI of the pen pointer V is discontinuous, the movement locus overlaps the skeleton several times. Or a closed trajectory surrounding the skeleton.

  FIG. 7 is a screen display during the contour setting process (process P4). When the previous drawing mode (processing step P3) confirms and specifies the end with a display button (not shown), the contour setting process is executed. In FIG. 7, VII is a clock display mark being processed.

  In the present invention, a region is set for each skeleton part of the perspective skeleton model. Then, the movement trajectory VI of the pen pointer V previously input in the drawing mode (processing step P3) is converted into a closed contour for each region of the skeleton part.

  In FIG. 7, the pen locus in the drawing mode is converted into a contour locus that is closed for each of the head a1, the body a2, the waist a3, the tail a4, the arm a5, and the leg a6 and displayed.

  FIG. 8 is a schematic diagram for explaining the contour setting (processing step P4). 8A and 8C are examples of the movement locus of the pen pointer V, and FIGS. 8B and 8D are diagrams in which contours are set corresponding to the movement locus of the pen pointer V in FIGS. 8A and 8C, respectively.

  Each of B1 and B2 is a skeleton part of a perspective skeleton model, and has a region R1 and R2 for each skeleton part as a feature in the present invention. The regions R1 and R2 provided for each skeleton part of the display object are part of the regions R1 and R2 so that no gap is generated between the regions R1 and R2 even when the skeleton part is moved by a joint. Are set to overlap.

  The movement trajectory t1 of the pen pointer V in FIG. 8A is one closed trajectory continuous across the regions R1 and R2, and surrounds the two skeleton parts B1 and B2. In such an example, the movement trajectory t1 of the pen pointer V is separated into regions R1 and R2 according to the present invention, and converted into contours closed in the regions R1 and R2, respectively. FIG. 8B shows contours tf1 and tf2 that are separated into two and set.

  In the example of FIG. 8C, the movement locus t2 of the pen pointer V surrounding the skeleton part B1 is not closed in the region R1, and the movement locus t3 of the pen pointer V surrounding the skeleton part B2 is closed.

  In such an example, the portion extending to the region R2 of the movement trajectory t2 of the pen pointer V is deleted according to the present invention and converted into a contour tf3 closed in the region R1 as shown in FIG. 8D. On the other hand, the trajectory t3 drawn in the region R2, that is, the movement trajectory t3 of the pen pointer V surrounding the skeleton part B2 is in a state of protruding from the region R2. Therefore, as shown in FIG. 8D, setting conversion is performed so as to close the region R2.

  In the contour setting step P4, the skeleton part, the region, and the movement locus of the pen pointer V are all set as bitmap data, so that calculation processing for conversion can be performed based on the bitmap coordinates.

  Returning to the flow of FIG. 2, two-dimensional (2D) display object data is generated by the contour setting step (processing step P4). Subsequently, the drawing model of the two-dimensional display object data is converted into three dimensions (3D) for each skeleton part (processing step P5).

  The algorithm described in the paper “Teddy: A Sketching Interface for 3D Freedom Design” submitted to ACMSIGGRAPH99 can be applied to make the drawing model of the two-dimensional display object data three-dimensional (3D).

  Here, for easy understanding, a general procedure of the 3D algorithm described in the above paper will be described with reference to similar drawings.

  9 to 12 are diagrams for explaining such a 3D algorithm. As described above, the movement locus of the pen pointer V closed for each skeleton part is obtained by the contour setting step (processing step P4).

  FIG. 9A is a diagram in which all sides are formed by a line segment of a certain length with respect to a closed movement locus of the pen pointer V obtained for a certain skeleton part. Next, a plurality of triangles are formed by connecting the end points of the formed sides (see FIG. 9B).

  At this time, the formed triangles can be classified into three. The first is a triangle having two external sides (FIGS. 9B and 90 to 93), and the second is a triangle having no external sides (connection triangle) (FIGS. 9B, 94, and 95). Further, the third is a triangle (sleeve triangle) having one outer side (FIG. 9B, 96 to 100).

  Here, when connecting the centers of the connecting triangles 94 and 95 and the centers of the sides of the sleeve triangles 96 to 100, a spinal column is obtained as shown by a thick line P in FIG. 9C. It introduces the pruning.

  That is, as shown in FIG. 10, a circle having a diameter of an inner side of a triangle (FIG. 9B, 90 to 93) having two outer sides of the first classification is drawn, and the vertex of the triangle is within the circle. If there is, the inner side is omitted and merged with the adjacent triangle (FIGS. 10A to 10B). If the adjacent triangle to be merged is the sleeve triangle, the merged polygon becomes a polygon figure having three outer peripheries (FIG. 10B).

  Next, a circle is similarly drawn with the inner side of the combined polygon as a diameter, and it is determined whether or not the vertex of the polygon is included in the circle. The above process is repeated until at least one vertex of the polygon is outside the circle, or until an adjacent triangle to be joined becomes a connected triangle having no second outer side.

  FIG. 10C is a diagram illustrating a case where the vertex of the polygon comes out of the circle. Further, FIG. 10D is a diagram in the case where the adjacent triangles to be combined are connected triangles having no second outer side.

  Next, in the case of FIG. 10C, the vertex of the polygon is connected to the midpoint of the inner side (see FIG. 11A), and in the example shown in FIG. 10D, the vertex of the outer side of the polygon is connected to the center point of the connection triangle. (See FIG. 11B)).

  In this way, a two-dimensional polygon figure obtained by subdividing the figure of FIG. 9 into triangles is obtained (FIG. 12A). Next, the triangle is divided by the spinal column indicated by the thick line P by connecting the midpoints of the inner sides of the sleeve triangle and the connecting triangle (FIG. 12B). Further, the resulting polygons P1, P2, and P3 are made into a triangle, and a complete two-dimensional triangular mesh is obtained (FIG. 12C).

  The obtained two-dimensional triangular mesh is then extended and converted into a three-dimensional mesh structure according to the algorithm described in the above paper. The extended conversion algorithm to the three-dimensional mesh structure described in this paper is illustrated by the diagram shown in FIG.

  The obtained spine side vertices are raised relative to the plane containing the vertices X, a, b, c, d, e in proportion to the average value of the distances between the vertices and the vertices directly in contact. For example, in FIG. 13A, the vertex X of the spine side (thick line) is in direct contact with the vertices a, b, c, d, and e. Accordingly, the average value of the distances between the vertex X and the vertex a, the vertex X and the vertex b, the vertex X and the vertex c, the vertex X and the vertex d, and the vertex X and the vertex e is increased. X ′ is converted (FIG. 13B).

  Further, the vertex X ′ thus converted and the vertex on the outer side are connected by an arc of a hemisphere (FIG. 13C). Next, an appropriate polygon mesh is obtained by sewing up the adjacent sides that have been raised (FIG. 13D).

  In accordance with the above description, the two-dimensional bitmap data drawn as shown in FIG. 7 is extended and converted into three-dimensional polygon data for each of the skeleton parts of the drawing model. This completes the rendering model 3D (processing step P5). Next, the polygon data of the 3D display object obtained in this way is stored (registered) in the RAM 3 (processing step P6).

  According to the present invention, the attribute parameter (corrected parameter) of the value obtained by correcting the attribute parameter (basic parameter) of the basic body according to the ratio of the contour locus corresponding to the skeleton model to the data of the basic body is expanded and converted to the cubic. As an example of a specific form to be attached to the data of the original display object image, when registering the polygon data of the 3D display object, an attribute parameter characterizing the action mode of the display object corresponding to the polygon data of the 3D display object is attached. Is done. Therefore, parameters attached to the RAM 3 together with polygon data of the 3D display object are set.

  As an example, in the present invention, a plurality of types of attribute parameters are prepared as attribute parameters that characterize the behavior mode. Each attribute parameter includes a basic parameter and a correction parameter.

  The basic parameter is a parameter that is determined in advance for the display object and that allows parameter values to be accumulated throughout the game. That is, a constant value is given as an initial value, and points are added every time a predetermined condition is satisfied throughout the game.

  On the other hand, the correction parameter is a parameter given corresponding to the form of the display object when the form of the display object is generated for the first time by drawing by the player or when the form is rewritten.

  First, three-dimensional basic body data having an average physique is prepared in advance for each of a plurality of display objects prepared in the skeleton selection menu display (processing step P1) according to the present invention. The CPU 2 calculates a parameter (attribute parameter) by comparing the three-dimensional basic body data with the drawn data.

  Here, as an embodiment, an attribute is defined for each part of the skeleton constituting each display object. For example, there is a skeleton shown in FIG. 14 as a humanoid display object, and there are parts of the head, arms, torso, waist, and legs, and power parameters that are an example of attribute parameters are defined for the arms and legs as part attributes. In addition, a speed parameter, which is another example of the attribute parameter, is defined in the leg.

  FIG. 15 shows a beast-shaped skeleton. The skeleton of FIG. 15A has a head, a torso, a waist, legs 1, a leg 2, and a tail, and the skeleton of FIG. 15B has a head, arms, and torso. , Waist, leg 1, leg 2 and tail parts. As part attributes, power parameters are set for the head, arms, and legs 1, and speed parameters are set for the legs 1 and 2.

Based on such skeletal part information, the following parameter values are used for the display object that has been contoured.
-Total volume: Total volume of all parts.
-Power part volume total: A part attribute of power is called a power part, and is the total volume of power parts defined in each skeleton.
-Power parts volume ratio: Ratio of the total power parts volume to the total volume. That is, (power parts volume total) / (total volume total).
-Speed part volume total: A part whose speed is a part attribute is called a speed part and is the total volume of speed parts defined in each skeleton.
・ Speed parts volume ratio: The ratio of the total speed parts volume to the total volume. That is, (speed parts volume total) / (total volume total).
-Average volume: Average volume in parts. That is, (total total volume) / (total number of parts).

  As a method of correcting the attribute parameter of the basic body according to the ratio of the contour locus corresponding to the skeleton model to the data of the basic body, for example, the power part volume total of the drawn display object obtained as described above, The power part volume ratio is compared with the corresponding volume and volume ratio of the three-dimensional basic body, and the correction value is set for the drawn display object as follows.

  How to find a correction value by comparing the total power parts volume: Every time the volume of the drawn part is 10% larger than the basic body, it is corrected by +1. Conversely, every time the volume of the drawn part is 10% smaller than the base body, it is corrected by -1.

  How to find the correction value by comparing the power part volume ratio: Every time the volume ratio of the drawn part is 10% larger than the basic body, it is corrected by +1. On the contrary, every time the volume ratio of the drawn part is 10% smaller than the basic body, it is corrected by -1.

  The correction parameter is obtained from the basic parameter as follows.

  Assuming that the power parameter of the basic body, which is an example of the basic parameter, is “5”, the correction power parameter of the drawn display object is 5+ (power parts volume total correction value) + (power parts volume ratio correction value) It becomes. That is, when the volume of the drawn part is 10% larger than the basic body, 5 + 1 = 6 is the modified power parameter.

  Similar to the calculation of the power parameter of the drawn display object, the correction speed parameter of the drawn display object is 5+ (speed parts volume total correction value) + (speed parts volume ratio correction value). In this case, the parameter speed of the basic body, which is another example of the basic parameter, is “5”.

  Both the power parameter and speed parameter of the display object rendered as described above are related to the volume of the skeleton part related to power and speed. Therefore, the player can predict and draw the parts corresponding to the behavior of the display object expected when the display object is drawn. 16 and 17 are diagrams for explaining this.

  In FIG. 16, it is a figure explaining the case where the form of an arm is changed as a part.

  In FIG. 16, the arm is lengthened (FIG. 16I), the arm is thickened (FIG. 16II), and the volume ratio occupied by the arm is increased (FIG. 16III) relative to the basic mold (FIG. 16O). Thereby, it is possible to provide a display object attribute with a strong punching force, which is a preferable form when generating an animal display object having an arm strength such as a gorilla.

  On the other hand, with respect to the basic type (FIG. 16O), the arm is shortened (FIG. 16IV), the arm is narrowed (FIG. 16V), and the volume ratio occupied by the arm is reduced (FIG. 16VI). As a result, it is possible to generate an arm having a decoration level with low power.

  FIG. 17 is a diagram illustrating a case where the shape of the legs is changed as a part.

  In FIG. 17, with respect to the basic mold (FIG. 17O), the legs are lengthened (FIG. 17I), the legs are narrowed (FIG. 17II), and the volume ratio occupied by the legs is increased (FIG. 17III). Thus, a display object attribute having a large speed power can be provided, which is a preferable form when generating a light and fast leg animal display object such as Impala.

  Furthermore, with respect to the basic type (FIG. 17O), the legs are shortened (FIG. 17IV), the legs are thickened (FIG. 17V), and the volume ratio occupied by the legs is reduced (FIG. 17VI). Thereby, it is possible to provide an animal display object attribute having a heavy weight and a large power, which is a preferable form when generating a heavy animal display object such as an elephant.

  In the above description, the attribute parameter setting is associated with the three-dimensional volume of the display object. However, the application of the present invention is not limited to this, and the area of the two-dimensional display object image as drawn, the basic The corresponding area of the body may be used for comparison.

  Furthermore, it is also possible to set a correction value related to the attack and defense level corresponding to the rendered form. FIG. 18 is a diagram for explaining this.

  As an example, a correction value for the attack and defense level is set according to the number of protrusions provided for each part of the drawn model. In FIG. 18A, a circled portion is a protrusion, and for example, a portion having an angle of 45 degrees or less is defined as a protrusion.

  For each part of the torso, arm, and leg, a correction value for the attack and defense level is set according to the number of protrusions provided. As an example, it is given as follows.

  When the number of protrusions in the body part is 0, the correction value for the attack power is set to +1. When the number of protrusions is 2 to 4, the correction value related to the attack power in the intersection range is set to +1. When the number of protrusions is 5 or more, the correction value for long range attack power is set to +1.

  When the number of protrusions in the arm part is 0, the correction value related to the defense power is set to 0. When the number of protrusions is 2 to 4, the correction value for the long range attack power is +2. When the number of protrusions is 5 or more, the correction value for the long range attack power is +3.

  Further, when the number of protrusions in the leg part is 0, the correction value related to the attack power is set to +2. When the number of protrusions is 2 to 4, the correction value related to the attack power in the crossing range is set to +2. When the number of protrusions is 5 or more, the correction value related to the attack power in the crossing range is set to +3.

  As shown in FIG. 18B, it is also possible to set correction values related to the attack and defense level for each part of the trunk, arm, and leg in accordance with the “smoothness degree” in the form of the part. That is, for each part of the torso, arms, and legs, correction values relating to the attack and defense level are set in the same manner as described with reference to FIG.

  Further, as shown in FIG. 18C, for each part of the torso, arm, and leg, the attack / defense level is the same as described for FIG. 18A according to the stroke length (short, average, long) of the part. Set the correction value for.

  Furthermore, the parameter value can be changed depending on the type of texture (material) attached to the displayed display object. That is, in the flow of FIG. 2, when registering the three-dimensional display object data, the player who performed the drawing further selects a texture suitable for the display object as a part of the attached parameter value.

  The correction value set to the selected texture is added, and the texture corresponding to the correction value is pasted at the time of drawing display. The following texture colors can be set for each attribute value and modification value.

  Here, the parameter given to the display object to be drawn as described above is updated not only at the time of one drawing but also to a new parameter correction value every time the drawing display object data is updated. .

  Further, in addition to the above parameter setting, it is possible to set a parameter related to the life of the display object.
