In the object change temporary storage step, when the image information of one object is output in the object image information output step during the joint movement of two adjacent objects, the joint of one object that is close to the other object Information including position information after performing joint movement at a bending angle smaller than the bending angle of the joint movement of the contour of the surface is derived, and the information is temporarily stored.

  According to the present invention, an image processing system or the like can derive position information at a bending angle smaller than a bending angle of joint movement performed by two objects when deriving position information of a contour line of a joint surface. it can.

  Thereby, an image processing system etc. can provide the joint surface which connects them smoothly between two objects. As a result, the user of the image processing system can enjoy a more natural display image.

  In the image processing system, the object change temporary storage means may change the object change when the image information of one object is output by the object image information output means during the joint movement of two adjacent objects. The position information of the contour line excluding the contour line of the one object that is temporarily stored by the temporary storage means and adjacent to the other object is the contour line of the other object, The position information of the contour line excluding the contour line of the joint surface close to the object is temporarily stored and stored, and the position information of the contour line of the joint surface close to the other object is the contour line of the one object May be stored continuously.

  In the image processing method, the object change temporary storage step may include the object change when the image information of one object is output in the object image information output step during the joint movement of two adjacent objects. The position information of the contour line excluding the contour line of the joint surface adjacent to the other object that is temporarily stored in the storing step is the contour line of the other object, The position information of the contour line excluding the contour line of the joint surface close to the object is temporarily stored and stored, and the position information of the contour line of the joint surface close to the other object is the contour line of the one object.

  According to this, since the image processing system or the like only needs to store the position information of the contour line of the object to be stored for each object, the necessary storage capacity can be made relatively small.

Further, in the image processing system, the information including the shape information includes position information of the contour line of the joint surface at one end of at least one of the two objects, and other information at the other end of the object.

  According to the present invention, an image processing system or the like can match the joint surfaces of each object by expanding and contracting a part of the side surface of each object during joint movement performed by adjacent objects. As a result, the image processing system or the like can display images by smoothly connecting the objects.

  In particular, according to the present invention, the image processing system or the like can expand and contract the entire side surface of the object by expanding and contracting the side surface between the surface formed by the lane markings and the joint surface of the object during joint movement. Thus, deformation can be prevented. As a result, the image processing system or the like can reduce the number of parts that are deformed during joint movement, and can perform more natural image display.

  In addition, according to the present invention, an image processing system or the like can smoothly connect adjacent objects by using most of the shape information when each object is formed as a fixed shape and expanding and contracting the side surfaces of the shape. be able to. Thereby, the image processing system or the like can effectively utilize the shape information of the display object that has been conventionally used.

  Furthermore, according to each of the above-described inventions, the image processing system and the like do not use the hidden surface removal process, and therefore can perform higher-speed image processing, and also when the joint motion is performed, the side surface of each adjacent object Can be prevented from crossing each other.

  When displaying a three-dimensional image, two objects (parts) adjacent to each other through the joint in the joint portion of the display object are formed so as to have a fixed shape as shown in FIG. In this case, the image display near the joint 10 becomes unsightly when the joint 10 moves (hereinafter referred to as “joint movement”).

  That is, when the two objects 12 and 14 adjacent to each other through the joint 10 have a fixed shape, the joint 10 has, for example, as shown in FIG. A tear 16 may be formed on the outside, and one end surface of any object may be exposed and displayed as an image.

  Alternatively, as shown in FIG. 1C, in a joint motion mode in which two objects 12 and 14 adjacent to each other at the joint portion overlap each other, the side surfaces of both objects intersect at the joint 10. For this reason, depending on the method of hidden surface processing, the displayed side surface frequently changes, and the image display may flicker.

  As described above, in any case, the image display of the joint portion becomes unsightly.

  In order to solve such a problem, in the present embodiment, instead of the conventional technique in which the display object is configured only by a combination of a plurality of objects having a fixed shape, an object whose side surface expands and contracts at the joint portion is used. A technique for displaying an image is provided.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 2 is a diagram illustrating an image of joint motion of two adjacent objects using a three-dimensional game device as the image processing system according to the present embodiment.

  The two objects A and B shown in FIG. 2 are formed in a hexagonal column shape by combining 12 polygons, and are smoothly connected so that the joint surfaces 18 are the same. Then, before and after the joint movement, six polygons (hereinafter referred to as “expandable polygons”) PB0 to PB5 that contact the object A in the object B expand and contract so that the object A and the object B are in contact with each other. The stretchable polygons PB3 to PB5 are not shown in the figure, and the stretchable polygons PB3, PB4, and PB5 are respectively arranged at positions facing the stretchable polygons PB0, PB1, and PB2 in order.

  As shown in FIG. 2, the adjacent end surfaces of the two objects are made to coincide with each other to form the joint surface 18, so that no tears are generated outside the joint portion during the joint movement of these objects A and B. This also prevents the end face of the joint portion of any object from being exposed and displaying an image. Further, since the side surfaces constituting the two objects do not intersect with each other, the hidden surface removal process of the joint portion can be suitably performed regardless of the hidden surface removal method.

  The stretchable polygons PB <b> 0 to PB <b> 5 are provided between the joint surface 18 and the other end surface 20 of the object B, and are partitioned by a partition line 22 provided corresponding to the joint surface 18. The dividing line 22 is provided at an intermediate position between the joint surface 18 and the other end surface 20. Thereby, it is possible to prevent the entire object B from being deformed during the joint motion.

  FIG. 3 is a diagram showing a configuration of the present three-dimensional game apparatus capable of obtaining such an image display.

  The three-dimensional game apparatus shown in FIG. 3 has a storage unit 30 in which information regarding each display object arranged in a virtual three-dimensional space (hereinafter referred to as “game space”) is stored. And the memory | storage part 30 is provided with the object information storage part 32 which memorize | stores the shape information of the outline of two adjacent objects mentioned above.

  Specifically, the object information storage unit 32 stores the basic arrangement of a plurality of polygons constituting each object as coordinate information based on a predetermined origin belonging to each object. A shape is specified. The shape stored here is a “basic shape”, and deformation processing or the like is performed when an image is displayed.

  In order to store the basic shape, the object information storage unit 32 stores a polygon vertex list and a polygon attribute list corresponding to each object. 4 and 5 are diagrams showing a polygon vertex list of the object A and the object B, and the vertex coordinates in the game space coordinate system of the polygons constituting each object and the names of the vertices are stored in association with each other.

  Here, the names of the vertices of each object are as shown in FIGS. That is, the object A is specified by 18 vertices from the vertices CA0 to CA5 and A0 to A11, and the object B is specified by the 18 vertices from the vertices CB0 to CB5 and B0 to B11.

  Here, the vertices CA0 to CA5 and CB0 to CB5 with C added to the initial letter of the code are the names of the vertices of the joint surface 18 of the object A and the object B, respectively. Stored in In addition, vertices having the same reference numerals like the vertex CA0 and the vertex CB0 represent vertices whose positions should coincide with each other.

  Also, in the polygon attribute list, as shown in FIGS. 8A and 8B, each polygon name PA0 to PA11, PB0 to PB11, a loop of four vertices specifying each polygon, and each polygon Attribute information APA0 to APA11 and APB0 to APB11 are stored correspondingly. The polygon attribute information APA0 to APA11 and APB0 to APB11 includes information about textures to be attached to the polygons PA0 to PA11 and PB0 to PB11.

  If the polygons are designated in this way, the arrangement of the polygons can be changed and the size and shape can be changed by changing the position coordinates of the vertices specifying each polygon.

  Information regarding the object A and the object B stored by such a method is subjected to predetermined arithmetic processing by the object change temporary storage unit 36 provided in the processing unit 34 shown in FIG. The object change temporary storage unit 36 is provided with a position information deriving unit 38 and a temporary storage unit 40. Based on the shape information of each object stored in the object information storage unit 32 and the motion information of the display object stored in the game program or the storage unit 30, the position information deriving unit 38 performs rotation, parallel movement, etc. of the object. Three-dimensional arithmetic processing is performed to derive position coordinate information in the game space. These pieces of information are stored in the temporary storage unit 40.

  Further, in the three-dimensional game device according to the present embodiment, an object connection unit 42 is provided in the object change temporary storage unit 36. The object connecting unit 42 replaces the information of the vertices CB0 to CB5 of the end face adjacent to the object A side of the object B with the information of the vertices CA0 to CA5 of the end face adjacent to the object B side of the object A and stores them in the temporary storage unit 40. By doing so, the object A and the object B are connected. Then, the object image information output unit 44 outputs image information to the display unit 46 based on the stored contents of the temporary storage unit 40 thus stored.

  FIG. 9 is a flowchart showing the processing procedure of the object change temporary storage unit 36. FIG. 10 is a conceptual diagram showing the storage contents of the temporary storage unit 40 in the processing of FIG. 9, and shows how vertex coordinates are stored aligned in a storage area. Hereinafter, based on these drawings, a specific procedure of processing for connecting the object A and the object B will be described.

  First, an area for storing and holding the count value i is secured in a work area (register) provided in the processing unit 34, and i = 0 is stored (step S1). Next, the object change temporary storage unit 36 reads one of the vertex coordinates from the polygon vertex list of the object A stored in the object information storage unit 32 (step S2).

  Further, the position information deriving unit 38 derives the position coordinates after the joint motion in the game space using the read coordinates (step S3), and stores them in the area (address) corresponding to the count value i of the temporary storage unit 40. (Step S4).

  Next, based on the value of the count value i, the processing unit 34 determines whether the vertex corresponding to the read coordinates is the final data (step S5). In the present embodiment, the count value i = 18 represents the final data. If it is not the final data, the count value i is decreased by 1 (step S6), and the coordinates of the next vertex are read (step S2).

  The above processing is repeated until the vertex data of the final data is performed (step S5). When all the vertex data of the object A are read, calculated, and stored, the object image information output unit 44 reads the stored contents of the temporary storage unit 40 and outputs image information according to the information (step S7). ). As shown in FIG. 10A, the temporary storage unit 40 at this time stores vertex coordinates belonging to the joint surface 18 of the object A in an area corresponding to the count value i = 0 to 5, and the count value i = Other vertex coordinates are stored in the area corresponding to 6-18. The stored coordinate information is continuously stored in the temporary storage unit 40 even after the information is read out.

  Next, the processing unit 34 resets the count value i as i = 6 (step S8). Further, the object change temporary storage unit 36 reads out the vertex coordinates corresponding to the count value i from the polygon vertex list of the object B (step S9). The position information deriving unit 38 derives the position coordinates after the joint movement in the game space using the read coordinates (step S10), and stores them in the area of the temporary storage unit 40 corresponding to the count value i (step S11). This state is shown in FIG.

  Next, it is determined whether it is the final data based on the count value i (step S12). If it is not the final data, the count value i is incremented by 1 (step S13). Then, the next vertex of the object B is read (step S9), and the same processing is repeated until the final data (step S12). Then, all vertex data of the object B are calculated and temporarily stored. That is, the vertex coordinates CA0 to CA5 stored in the temporary storage unit 40 are retained as they are, and only the vertex coordinates B0 to B11 belonging only to the object B are stored as the vertex coordinates A0 to A11 belonging only to the object A. Overwrite the area that has been changed and store it. Then, the object image information output unit 44 reads the temporary storage unit 40 and outputs the image information according to the information (step S14).

  In the processing described above, the polygon vertex list of the object stored in the object information storage unit 32 is once read into the temporary storage unit 40, and the vertices belonging to the joint surface are replaced with predetermined vertices. That is, only the vertex of the joint surface is replaced with the vertex coordinate of the joint surface of another object, and the other vertexes effectively use the existing shape information of the object. Accordingly, it is not necessary to newly create object shape information, and the image processing of this embodiment can be performed relatively easily.

  Further, the information to be stored in the temporary storage unit 40 is the vertex coordinates of the polygon of the object A or the object B. These pieces of information are stored in the temporary storage unit 40 for each object. Therefore, it is possible to smoothly connect the object A and the object B using the temporary storage unit 40 having a relatively small storage capacity so that the joint surfaces thereof coincide with each other. If a temporary storage unit having a relatively large storage capacity is used, it is not necessary to read the temporary storage unit for each object.

  Next, an example of image display when the above-described processing is applied to the joint motion of two adjacent objects in the game space is shown.

  FIG. 11 is a diagram showing a display image of the knee when both the object constituting the thigh and the object constituting the heel have a fixed shape, and FIG. 12 is a three-dimensional game according to the present embodiment. It is a figure which shows the display image of a knee part when a division line and an expansion-contraction polygon are provided in a part of object which comprises a thigh by an apparatus. As shown in these figures, by providing a stretchable polygon on at least one of two objects adjacent to each other via the joint, a very suitable image display of the knee can be obtained.

  In addition, various deformation | transformation are possible for the said Example. For example, each object can be expanded and contracted relatively easily even when the position and shape of the object are specified by the position coordinate of the contour line instead of specifying the polygon constituting each object by the position coordinate of the vertex.

  Further, in the above-described processing, three-dimensional calculation is performed on both joint surfaces of two adjacent objects (see FIG. 9 and steps S3 and S10). The three-dimensional operation on the surface can be omitted.

  Further, when three or more objects are connected to perform joint movement, the above-described processing is repeated, so that images can be displayed so that the respective end faces coincide with each other.

  FIG. 13 and FIG. 14 are diagrams showing display images in which two objects constituting the thigh are connected to objects constituting the buttocks. FIG. 13 shows a case where each object has a fixed shape. In the example shown in FIG. 13, a tear has occurred between the object constituting the buttocks and the object constituting the thigh. On the other hand, FIG. 14 shows a case where a lane marking and a stretchable polygon are provided on a part of an object constituting the thigh by the three-dimensional game apparatus according to the present embodiment. In the example shown in FIG. 14, the object forming the buttocks and the object forming the thigh are smoothly connected.

  Further, in the display image shown in FIG. 14, a texture representing clothing worn by the game character is mapped to the stretchable polygon. For this reason, according to the present three-dimensional game apparatus, the appearance of the clothes expanding and contracting during joint movement is displayed as an image, and the reality of the display image can be further improved.

(Second embodiment)
Next, a second embodiment of the present invention will be described.

  The present embodiment relates to a three-dimensional game apparatus in which part of the side surfaces of both objects expands and contracts during joint movement performed by two adjacent objects, and both are smoothly connected. In the description of the present embodiment, the same items as those already described in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  FIG. 15 is a diagram illustrating an image of joint motion of two adjacent objects using the three-dimensional game device according to the present embodiment. The two objects A and B shown in FIG. 15 are formed in a hexagonal prism shape by a combination of 12 polygons, and are smoothly connected so that the joint surfaces 100 are the same. Then, before and after the joint movement, the six stretchable polygons PA0 to PA5 in contact with the object B in the object A and the six stretchable polygons PB0 to PB5 in contact with the object A in the object B are in contact with each other. Expand and contract.

  Note that the stretchable polygons PA3 to PA5 are not shown, and the stretchable polygons PA3, PA4, and PA5 are arranged in positions facing the stretchable polygons PA0, PA1, and PA2, respectively. Further, the stretchable polygons PB3 to PB5 are not shown, and the stretchable polygons PB3, PB4, and PB5 are arranged at positions facing the stretchable polygons PB0, PB1, and PB2, respectively, in order.

  As shown in FIG. 15, the adjacent end surfaces of two objects are made to coincide with each other to form the joint surface 100, so that no tear occurs outside the joint portion during joint movement of the objects A and B, and any object The end face of the joint part is also exposed and no image is displayed. Further, since the side surfaces constituting the two objects do not intersect each other, the hidden surface removal processing of the joint portion can be suitably performed regardless of the hidden surface removal method.

  The stretchable polygons PA0 to PA5 are provided between the joint surface 100 and the other end surface 102A of the object A, and are partitioned by a partition line 104A provided corresponding to the joint surface 100. The partition line 104A is provided at an intermediate position between the joint surface 100 and the other end surface 102A. The stretchable polygons PB <b> 0 to PB <b> 5 are provided between the joint surface 100 and the other end surface 102 </ b> B of the object B, and are partitioned by a partition line 104 </ b> B provided corresponding to the joint surface 100. The partition line 104B is provided at an intermediate position between the joint surface 100 and the other end surface 102B. Thereby, it is possible to prevent the entire objects A and B from being deformed during joint movement.

  FIG. 16 is a view of the object A and the object B viewed from a direction perpendicular to the surface on which the joint motion is performed, and shows the objects A and B when the joint motion at the bending angle θ is performed. .

  As shown in FIG. 16, the objects A and B have a bending angle θ around the joint point 105. For example, the angle formed by the surface including the lane marking 104A and the surface including the lane marking 104B is equal to the bending angle θ. The angle formed by the joint surface 100 and the surface including the lane marking 104A or the lane marking 104B is equal to half the bending angle θ.

  FIG. 17 is a diagram showing a configuration of a three-dimensional game apparatus capable of obtaining such an image display. The 3D game device shown in FIG. 17 has substantially the same configuration as that of the 3D game device according to the first embodiment described with reference to FIG. Instead, a joint surface setting unit 106 is provided. The joint surface setting unit 106 performs three-dimensional coordinate conversion including rotation of the half of the bending angle θ of the joint motion on the joint surface 100 and stores the information in the temporary storage unit 40.

  The blocks other than the joint surface setting unit 106 are substantially the same as those of the three-dimensional game device according to the first embodiment. That is, the object information storage unit 32 stores the polygon vertex list described with reference to FIGS. 4 and 5 and the polygon attribute list described with reference to FIGS. 8A and 8B. The vertex coordinates of the vertices CA0 to CA5 and CB0 to CB5 concerning the vertices of the joint surface 100 are stored on the top side of each polygon vertex list. In addition, vertices having the same reference numerals like the vertex CA0 and the vertex CB0 represent vertices whose positions should coincide with each other.

  18 and 19 are flowcharts illustrating the processing procedure of the three-dimensional game device according to the present embodiment. FIG. 20 is a conceptual diagram showing the storage contents of the temporary storage unit 40 in the processing shown in FIGS. 18 and 19, and shows how vertex coordinates are stored aligned in a storage area. Hereinafter, a specific procedure of processing for connecting the objects A and B will be described with reference to these drawings.

  First, an area for storing and holding the count value i is secured in a work area (register) provided in the processing unit 34, and i = 0 is stored (step S101). Next, the object change temporary storage unit 36 reads the vertex coordinates CA0 of the joint surface 100 from the polygon vertex list of the object A stored in the object information storage unit 32 (step S102).

  Here, the joint surface setting unit 106 derives the position coordinates after the joint movement in the game space of the vertex coordinates CA0 (step S103), and stores them in the area (address) corresponding to the count value i in the temporary storage unit 40 ( Step S104). This state is shown in FIG.

  At this time, the joint surface setting unit 106 derives a position when the joint movement is performed at a bending angle θ of half of the joint movement angle θ between the object A and the object B and θ / 2. Next, based on the count value i, the processing unit 34 determines whether or not the vertex relating to the read coordinates is the final data of the joint surface 100 (step S105).

  In this embodiment, the count value i = 6 represents the final data. If it is not the final data, the count value i is incremented by 1 (step S106), and the vertex coordinates of the next joint surface 100 are read (step S102). Then, the above processing is repeated until the vertex coordinate CA5 related to the final data is performed (step S105).

  Next, the object change temporary storage unit 36 reads the coordinates of vertices other than the vertices on the joint surface 100 from the polygon vertex list of the object A stored in the object information storage unit 32 (step S107). The position information deriving unit 38 derives position coordinates after joint movement in the game space using the read coordinates (step S108), and stores them in the area corresponding to the count value i in the temporary storage unit 40 (step S109). At this time, the position information deriving unit 38 performs a calculation based on the bending angle θ in the joint motion, unlike the three-dimensional conversion process in the joint surface setting unit 106.

  Then, based on the value of the count value i, the processing unit 34 determines whether the vertex relating to the read coordinates is the final data (step S110). In the present embodiment, the count value i = 18 represents the final data. If it is not the final data, the count value i is incremented by 1 (step S112), and the coordinates of the next vertex are read (step S107).

  The above processing is repeated until the vertex data relating to the final data is performed (step S110). When reading, calculation, and storage of all vertex data of the object A are completed, the object image information output unit 44 is a temporary storage unit. 40 stored contents are read and image information is output according to the information (step S112). As shown in FIG. 20B, the temporary storage unit 40 at this time stores vertex coordinates belonging to the joint surface 100 in an area corresponding to the count value i = 0 to 5, and the count value i = 6 to 18 The coordinates of vertices other than the vertices belonging to the joint surface 100 of the object A are stored in the area corresponding to. In the temporary storage unit 40, the stored coordinate information is continuously stored even after the information is read out.

  Next, the processing unit 34 resets the count value i as i = 6 (step S113), and the object change temporary storage unit 36 reads the vertex coordinate B0 corresponding to the count value from the polygon vertex list of the object B (step S113). Step S114). The position information deriving unit 38 derives the position coordinates after the joint movement in the game space using the read coordinates (step S115), and stores them in the area of the temporary storage unit 40 corresponding to the count value i (step S116). The state is shown in FIG.

  Next, it is determined whether it is the final data based on the count value i (step S117). If it is not the final data, the count value i is incremented by 1 (step S118). Then, the next vertex of the object B is read (step S114), and the same processing is repeated until the final data (step S117). Then, all vertex data of the object B are calculated and temporarily stored.

  That is, the vertex coordinates CA0 to CA5 stored in the temporary storage unit 40 are retained as they are, and only the vertex coordinates B0 to B11 belonging only to the object B are stored as the vertex coordinates A0 to A11 belonging only to the object A. Overwrite the area that has been saved. This state is shown in FIG.

  Thereafter, the object image information output unit 44 reads the temporary storage unit 40 and outputs image information in accordance with the information (step S119).

  As described above, according to the present embodiment, similarly to the 3D game device according to the first embodiment, the polygon vertex list of the object stored in the object information storage unit 32 is once read into the temporary storage unit 40, and the joint The vertex belonging to the face is replaced with a predetermined vertex. In particular, in this embodiment, the joint surface position coordinate deriving unit 106 is different from the joint motion of the bending angle θ that the objects A and B originally perform with respect to the vertexes belonging to the joint surface 100, and the bending angle θ / 2. The three-dimensional coordinate conversion representing the joint motion is performed. In addition, the position information deriving unit 38 performs three-dimensional coordinate conversion representing the joint motion at the bending angle θ on vertices other than the vertices belonging to the joint surface 100. Then, the image shown in FIG. 15 can be displayed by synthesizing with the polygons specified by the vertices derived in this way.

  In addition, by performing such processing, the three-dimensional game device according to the present embodiment can expand and contract part of both side surfaces of the objects A and B, and smoothly connect both objects during joint movement. Thereby, compared with the case of the three-dimensional game apparatus in the first embodiment, the image of the joint portion can be displayed more naturally.

  Further, in the three-dimensional game device according to the present embodiment, since the joint surface that performs the joint motion of the gentler bending angle than the joint motion performed by the objects A and B is provided in the region between the two objects, Even when the objects A and B perform joint motion with a large bending angle, it is possible to display images of natural joint portions.
