Description of the Related Art Conventionally, an image of a display object composed of a combination of a plurality of objects (parts) performing various operations in a virtual three-dimensional space constructed in a storage device is output as an image. Three-dimensional game devices that play are widely popular.

By the way, in this type of three-dimensional game device, it is essential to smoothly display the movement of the display object in the virtual three-dimensional space in order to enhance the entertainment property of the three-dimensional game device, and therefore it is necessary. A technique for smoothing the image display of the joint portion of the display object without complicating the image processing has been desired.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a three-dimensional game apparatus and an image synthesizing method capable of suitably displaying an image of a joint portion of a display object. It is an issue.

[0005]

According to the present invention, a joint movement performed by at least a first object and a second object adjacent to each other among a plurality of objects constituting a display object in a virtual three-dimensional space is displayed in real time 3 In the three-dimensional game device, a first joint surface formed by a part of a contour line of the first object and close to the second object is formed by a part of a contour line of the second object. At least one side surface of the first or second object expands or contracts when the joint movement is performed so as to coincide with a second joint surface that is close to the surface.

According to the present invention, the joint surfaces of both objects coincide with each other and are smoothly connected to each other for image display during joint motion of adjacent objects. Therefore, the player of the present three-dimensional game device can enjoy a more natural display image.

Further, according to the present invention, it is possible to prevent the side surfaces of adjacent objects which perform joint motion from intersecting each other. Therefore, in the present three-dimensional game device, the hidden surface erasing process can be suitably performed regardless of the processing method.

Further, according to the present invention, most of the shape information when the first and second objects are formed as fixed shapes is diverted, and the side surfaces of the shapes are expanded and contracted to smoothly connect adjacent objects. can do. Therefore, it is possible to effectively utilize the shape information of the display object that has been conventionally used.

The present invention is also a three-dimensional game apparatus for displaying in real time the joint movements of at least the first object and the second object which are adjacent to each other among a plurality of objects constituting a display object in the virtual three-dimensional space. Then, the second object is partitioned by a partition line formed corresponding to a contour line of a second joint surface which is formed by a part of a contour line of the second object and is close to the first object, A surface formed by the demarcation line and the second joint surface such that a first joint surface formed by a part of the contour line of the first object and close to the second object coincides with the second joint surface. The side surface between and expands and contracts when the joint movement is performed.

According to the present invention, the second object is demarcated by a demarcation line. Then, during the joint movement, the side surface between the surface formed by the lane marking and the second joint surface of the second object (the joint surface close to the first object) expands and contracts. Therefore, the entire side surface of the second object does not expand and contract and deform. As a result, it is possible to further reduce the portion that is deformed during the joint movement, and it is possible to display a more natural image.

Further, the present invention is a three-dimensional game device for displaying in real time the joint movements performed by at least two adjacent objects among a plurality of objects constituting a display object in a virtual three-dimensional space.

According to the present invention, the object connecting means shares the position information of the contour line of the joint surface of the adjacent objects with the position information of the contour line of one of the joint surfaces. Then, the image display is performed again based on the shape information of the contour lines of both objects thus configured. Then, when the joint is moved, the two adjacent objects having the same joint surfaces are smoothly connected.

The image processing apparatus further includes object image information output means for outputting image information of the object based on the information stored by the object change temporary storage means, and the object change temporary storage means comprises a plurality of objects constituting the display object. Information of one of the objects, the object image information output means outputs the image information of the object related to the information temporarily stored by the object change temporary storage means for each object at any time, The object connecting means is configured to temporarily store the object change temporary storage means when the image information of one object is output by the object image information output means during the joint motion of two adjacent objects. object Position information of the joint surface other than the contour line of the joint surface that is close to the other object, and the contour line of the joint surface that is the contour line of the other object and that is close to the one object. It is preferable to change the position information of the contour line to be excluded and temporarily store it, and continuously store the position information of the contour line of the joint surface which is the contour line of the one object and is close to the other object.

In this way, the position information of the contour line of the joint surface of the temporarily stored position information of the contour line of the object can be used as the position information of the joint surface of the other adjacent object, and the adjacent position information can be used. Both joint surfaces of the object can be made to coincide with each other and smoothly connected at the joint surfaces. Further, it is sufficient to store the position information of the outline of the object to be stored by the object change temporary storage means for each object, and the required storage capacity can be made relatively small.

BEST MODE FOR CARRYING OUT THE INVENTION In the process of developing a three-dimensional game device, the present inventor has shown in FIG. As shown in the figure, when all of them are formed so as to have a fixed shape, they have recognized the problem that the image display in the vicinity of 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 via the joint 10 both have a fixed shape, for example, as shown in FIG. There is a problem that the split 16 is generated and one end surface of one of the objects is exposed and an image is displayed.

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

As described above, in any case, the image display of the joint portion is unsightly, and the entertaining property of the three-dimensional game device is significantly impaired.

In order to solve such a problem, the present inventor has reviewed the conventional technique in which a display object is constructed only by combining a plurality of objects having a fixed shape, and an object whose side surface expands and contracts at a joint part. We came up with the invention of displaying images.

(First Embodiment) A first embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a diagram showing an image display of the joint motion of two adjacent objects using the three-dimensional game device according to this embodiment. The two objects A and B shown in the figure are formed into a hexagonal column shape by combining 12 polygons, and each joint surface 1
8 are the same and are connected smoothly. Then, before and after the joint movement, the six polygons (hereinafter, referred to as "expandable polygons") PB0 ... PB5 in contact with the object A in the object B are the object A.
And the object B expand and contract so as to contact each other.
The expansion / contraction polygons PB3 ... PB5 are not shown,
The expansion / contraction polygons PB3, PB4, PB5 are arranged in positions facing the expansion / contraction polygons PB0, PB1, PB2, respectively.

As shown in the figure, if the adjacent end faces of two objects are made to coincide with each other to form a joint surface 18,
When the joints of these objects A and B are jointly moved, no cracks are formed outside the joints, and the end faces of the joints of both objects are exposed and not displayed as an image.
Further, since the side surfaces forming the two objects do not intersect with each other, it is possible to preferably perform the hidden surface removal processing on the joint portion regardless of the hidden surface removal method. The expansion / contraction polygons PB0 ... PB5 are partitioned by a partition line 22 provided between the joint surface 18 and the other end surface 20 of the object B and provided corresponding to the joint surface 18. The partition line 22 is provided at an intermediate position between the joint surface 18 and the other end surface 20. By doing so, it is possible to prevent the entire object B from being deformed during the joint movement.

FIG. 3 is a diagram showing the configuration of the present three-dimensional game device capable of obtaining such an image display. The three-dimensional game device shown in the figure has a storage unit 30 in which information about each display object arranged in a virtual three-dimensional space (hereinafter referred to as “game space”) is stored. And
The storage unit 30 is particularly provided with an object information storage unit 32 that stores the shape information of the contour lines of the two adjacent objects described above. Specifically, the object information storage unit 32 stores the basic arrangement of a plurality of polygons forming each object as coordinate information based on a predetermined origin belonging to each object, and the basic shape of the object is stored according to the information. Is specified. The shape stored here is a "basic shape", and a deformation process or the like is performed when displaying an image.

In order to store this 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 polygon vertex lists of the object A and the object B. The vertex coordinates in the game space coordinate system of the polygons forming each object and the name of the vertex are stored in association with each other. Here, the names of the vertices of each object are determined as shown in FIGS. 6 and 7, and the object A has vertices CA0 ... CA.
5, object A is designated by 18 vertices up to A11, and object B has vertices CB0 ... CB5, B0 ... B1.
Specified by 18 vertices up to 1. Here, vertices CA0 ... CA5, CB0 ...
CB5 is the name of the vertex of the joint surface 18 of the object A and the object B, respectively, and their vertex coordinates are stored at the head side of each polygon vertex list. Further, vertices having the same numbers attached to the symbols, such as vertices CA0 and CB0, represent vertices whose positions should match each other.

Further, in the polygon attribute list, as shown in FIGS. 8A and 8B, the names of the polygons PA0 ... PA11,
PB0 ... PB11 and a loop of four vertices that specify each polygon, and attribute information APA0 ... APA1 of each polygon
1, APB0 ... APB11 are stored in association with each other. Attribute information APA0 ... APA11, A of this polygon
PB0 ... APB11 are polygons PA0 ... PA11, P
B0 ... PB11 includes information about the texture to be pasted.

If polygons are designated in this way,
By changing the position coordinates of the vertices that specify each polygon, it is possible to change not only the arrangement of the polygons but also the size and shape.

Information about the objects A and B stored as described above is stored in the object change temporary storage unit 36 provided in the processing unit 34 (see FIG. 3).
Then, a predetermined arithmetic processing is performed and is temporarily stored. The object information temporary storage unit 36 includes a position information derivation unit 38.
And a temporary storage unit 40, and the position information derivation unit 38 uses the shape information of each object stored in the object information storage unit 32 and the operation of the display object stored in the game program or the storage unit 30. Based on the information, three-dimensional calculation processing such as rotation and parallel movement of the object is performed to derive position coordinate information in the game space, and these pieces of information are stored in the temporary storage unit 40.

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

FIG. 9 shows the object change temporary storage unit 3
It is a flowchart which shows the processing procedure of 6. Further, FIG. 10 is a conceptual diagram showing the storage contents of the temporary storage unit 40 in the same process, and shows a state in which the vertex coordinates are aligned and stored in the storage area. Hereinafter, a specific procedure of the process of connecting the object A and the object B will be described based on 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 (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 (S2). Further, the position information deriving unit 38 derives the position coordinate after the joint motion in the game space using the read coordinates (S3), and stores it in the area (address) of the temporary storage unit 40 corresponding to the count value i. (S4). Next, the processing unit 34 determines whether the vertex associated with the read coordinates is the final data based on the count value i (S5). In the case of this example, the count value i = 18 represents the final data. If it is not the final data, the count value i is incremented by 1 (S6), and the coordinates of the next vertex are read (S6).
2). The above processing is repeated until the vertex coordinates of the final data are performed (S5), and when all the vertex data of the object A are read, calculated, and stored, the object image information output unit 44 causes the temporary storage unit to operate. Four
0 is read and image information is output according to the information (S7). As shown in FIG. 10A, the temporary storage unit 40 at this time stores the vertex coordinates belonging to the joint surface 18 of the object A in the area corresponding to the count values i = 0 to 5, and the count values i = 6 to 18 Other vertex coordinates are stored in the area corresponding to. The coordinate information stored in the temporary storage unit 40 is continuously stored even after the information is read out.

Next, the processing unit 34 sets the count value i to i =
It is reset as 6 (S8), and the object change temporary storage unit 36 reads the coordinates of the vertex corresponding to the count value i from the polygon vertex list of the object B (S9). The position information deriving unit 38 derives the position coordinate after the joint motion in the game space using the read coordinates (S10) and stores it in the area of the temporary storage unit 40 corresponding to the count value i (S11, see FIG. 10B). . Next, it is determined whether the data is the final data based on the value of the count value i (S12), and if it is not the final data, the count value i is incremented by 1 (S13). Then, the next vertex of the object B is read (S9), and the same processing is repeated until the final data (S12). Then, all vertex data of the object B are calculated and temporarily stored. That is, the temporary storage unit 4
The vertex coordinates CA0 ... CA5 stored in 0 are retained as they are, and the vertex coordinates B0 ... B11 belonging only to the object B are overwritten in the area where the vertex coordinates A0 ... A11 belonging only to the object A are stored. And change and memorize. After that, the object image information output unit 44 reads the temporary storage unit 40 and outputs image information according to the information (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 vertices of the joint surface are replaced with the vertex coordinates of the joint surface of another object, and the other vertices effectively use the existing shape information of the object. By doing so, it is not necessary to newly create the shape information of the object in implementing the present invention, and the present invention can be implemented relatively easily.

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, and these are stored in the temporary storage unit 40 for each object. Therefore, the object A and the object B can be smoothly connected by using the temporary storage unit 40 having a relatively small storage capacity so that their joint surfaces match. 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 in the case where the above-described processing is applied to the joint motion of two adjacent objects in the game space will be shown.

FIG. 11 is a diagram showing a display image of the knee when both the object forming the thigh and the object forming the arm have a fixed shape.
FIG. 2 is a diagram showing a display image of the knee when the lane markings and stretchable polygons are provided on a part of the object forming the thigh by the three-dimensional game device according to the present embodiment. As shown in these figures, by providing a stretchable polygon on at least one of two objects that are adjacent to each other via a joint, it is possible to obtain a very suitable image display of the knee.

The above embodiment can be modified in various ways. 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 coordinates of the contour line instead of specifying the polygons forming each object by the position coordinates of the vertices.

In the above-mentioned processing, two adjacent
Although the three-dimensional calculation is performed on both joint surfaces of one object (see FIGS. 9, S3 and S10), since both joint surfaces are the same surface, the three-dimensional calculation on either one of the joint surfaces can be omitted.

Further, even when three or more objects are connected to perform joint movement, it is possible to display an image so that the respective end faces coincide with each other by repeating the above-mentioned processing.

FIGS. 13 and 14 are views showing a display image in which two objects constituting the thigh are connected to an object constituting the buttocks. FIG. 13 shows a case where all the objects have a fixed shape, and a rift is formed between the object forming the buttocks and the object forming the thigh. On the other hand, FIG. 14 shows a case where a parting line and a stretchable polygon are provided on a part of the object forming the thigh by the three-dimensional game device according to the present embodiment, and the object forming the buttocks and the thigh Are smoothly connected to the objects that make up.

Further, in the display image shown in the figure, the texture representing the clothes worn by the player is mapped to the stretchable polygon. Therefore, according to the three-dimensional game device, the state in which the clothes expand and contract during the joint movement is displayed as an image, and the reality of the displayed image is further increased.

(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 a part of the side surfaces of both adjacent objects expands and contracts during the joint motion of two adjacent objects, so that the two are smoothly connected. In the description of the present embodiment, the same items as those already described in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

FIG. 15 is a diagram showing an image display of joint motion of two adjacent objects using the three-dimensional game device according to this embodiment. The two objects A and B shown in the figure are formed into a hexagonal column shape by combining 12 polygons, and each joint surface 1
00 are the same and are connected smoothly.
Then, before and after the joint movement, the six expansion / contraction polygons PA0 ...
PA5 and the six expansion / contraction polygons PB0 ... PB5 in contact with the object A in the object B expand / contract so that the object A and the object B are in contact with each other.

The expansion / contraction polygons PA3 ... PA5 are not shown, and the expansion / contraction polygons PA3, PA4, PA5 are arranged at positions facing the expansion / contraction polygons PA0, PA1, PA2, respectively. In addition, the expansion / contraction polygon PB3 ...
PB5 is also not shown, and the expansion / contraction polygons PB3, PB
4 and PB5 are expansion / contraction polygons PB0 and PB, respectively.
1, and is arranged at a position facing PB2.

As shown in the figure, if the adjacent end faces of the two objects are made to coincide with each other to form the joint surface 100, no crevice will occur outside the joint portion during joint movement of these objects A and B. , The end faces of the joint parts of any of the objects are exposed and not displayed as an image. Further, since the side surfaces forming the two objects do not intersect with each other, it is possible to preferably perform the hidden surface removal processing on the joint portion regardless of the hidden surface removal method. The expansion / contraction polygons PA0 ... PA5 are partitioned by a partition line 104A provided between the joint surface 100 and the other end surface 102A of the object A and 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. Further, the extendable polygon PB0 ... PB5 is the joint surface 1 provided between the other end face 102B of the articular surface 100 and object B
It is partitioned by a partition line 104B provided corresponding to 00. The lane marking 104B is the joint surface 100.
And the other end surface 102B.
By doing so, it is possible to prevent the entire objects A and B from being deformed during the joint movement.

FIG. 16 is a view of the object A and the object B as seen from the direction perpendicular to the plane in which the joint motion is performed. The object A and the object B perform the joint motion of the bending angle θ. Both objects A and B in the case
Is shown.

As shown in the figure, the object A and the object B form a bending angle θ around the joint point 105. For example, the surface including the marking line 104A and the marking line 1
The angle formed by the surface including 04B is equal to the bending angle θ. The angle formed by the joint surface 100 and the surface including the marking line 104A or the marking line 104B is equal to half the bending angle θ.

FIG. 17 is a diagram showing the structure of the present three-dimensional game device capable of obtaining such an image display. The three-dimensional game device shown in the figure has substantially the same configuration as the three-dimensional game device according to the first embodiment shown in FIG.
Particularly, a joint surface setting unit 106 is provided in the position information derivation unit 38 instead of the object connection unit 42. The joint surface setting unit 106 performs three-dimensional coordinate conversion on the joint surface 100, including rotation of a half of the bending angle θ of the joint movement, and stores the information in the temporary storage unit 40. .

The blocks other than the joint surface setting unit 106 are almost the same as those of the three-dimensional game apparatus according to the first embodiment. That is, in the object information storage unit 32, the polygon vertex list already shown in FIGS.
The polygon attribute list already shown in B is stored. Then, the vertex C applied to the vertex of the joint surface 100
The vertex coordinates of A0 ... CA5, CB0 ... CB5 are stored at the head side of each polygon vertex list. Also, the top CA
The vertices having the same numbers as 0 and the vertex CB0 represent vertices whose positions should match each other.

18 and 19 are flow charts showing the processing procedure of the three-dimensional game apparatus according to this embodiment. Also, FIG.
0 is a conceptual diagram showing the contents stored in the temporary storage unit 40 in the same process, showing that the vertex coordinates are aligned and stored in the storage area. Hereinafter, a specific procedure of the process of connecting the object A and the object B will be described based on 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 (S101). Next, the object change temporary storage unit 36 stores the object information storage unit 32.
The vertex coordinates CA0 of the joint surface 100 are read from the polygon vertex list of the object A stored in S10 (S10).
2). Here, the joint surface setting unit 106 derives the position coordinate of the vertex coordinate CA0 after the joint movement in the game space (S
103), and stores it in the area (address) corresponding to the count value i of the temporary storage unit 40 (S104, FIG. 20).
(See A). At this time, the joint surface setting unit 106 derives the position in the case where the joint motion is performed at a bending angle of θ / 2, which is half the bending angle θ of the joint motion between the object A and the object B. Next, the processing unit 34 determines, based on the value of the count value i, that the vertex associated with the read coordinates is the joint surface 10.
It is determined whether the final data is 0 (S105). still,
In the case of this example, the count value i = 6 represents the final data.
If it is not the final data, the count value i is incremented by 1 (S106), and the vertex coordinates of the next joint surface 100 are read (S102). Then, the above processing is repeated until the vertex coordinate CA5 relating to the final data is performed (S105).

Next, the object change temporary storage unit 36 reads the coordinates of the 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 (S107). The position information deriving unit 38 derives the position coordinates after the joint motion in the game space using the read coordinates (S10).
8), store in the area corresponding to the count value i of the temporary storage unit 40 (S109). At this time, the position information derivation unit 38, unlike the three-dimensional conversion process in the joint surface setting unit 106, performs a calculation based on the bending angle θ in the joint movement. Then, the processing unit 34 determines, based on the value of the count value i, whether the vertex corresponding to the read coordinates is the final data (S110). In the case of this example, the count value i = 18 represents the final data. If it is not the final data, the count value i is incremented by 1 (S112), and the coordinates of the next vertex are read (S10).
7). The above processing is repeated until the vertex coordinates of the final data are performed (S110), and when all the vertex data of the object A are read, calculated, and stored, the object image information output unit 44 causes the temporary storage unit to operate. 40 is read and image information is output according to the information (S112). As shown in FIG. 20B, the temporary storage unit 40 at this time stores the vertex coordinates belonging to the joint surface 100 in the area corresponding to the count values i = 0 to 5, and corresponds to the count values i = 6 to 18. The coordinates of the vertices other than the vertices belonging to the joint surface 100 of the object A are stored in the area. The coordinate information stored in the temporary storage unit 40 is continuously stored even after the information is read out.

Next, the processing unit 34 sets the count value i to i =
It is reset as 6 (S113), and the object change temporary storage unit 36 reads the vertex coordinates B0 corresponding to the count value from the polygon vertex list of the object B (S11).
4). The position information deriving unit 38 derives the position coordinates after the joint motion in the game space using the read coordinates (S1
15), and stores it in the area of the temporary storage unit 40 corresponding to the count value i (S116, see FIG. 20C). Next, it is determined whether the data is the final data based on the count value i (S11
7) If it is not the final data, the count value i is incremented by 1 (S118). And object B
The next vertex is read (S114), and the same process is repeated until the final data (S117). Then, all vertex data of the object B are calculated and temporarily stored.
That is, the vertex coordinates CA0 stored in the temporary storage unit 40
.. CA5 retains the stored contents as it is, and changes and stores only the vertex coordinates B0 ... B11 that belong only to the object B by overwriting the area where the vertex coordinates A0 ... A11 that belong only to the object A were stored (FIG. 20C). reference).
Then, the object image information output unit 44 reads the temporary storage unit 40 and outputs the image information according to the information (S119).

According to the above-described processing, similarly to the three-dimensional game apparatus according to the first embodiment, the polygon vertex list of the object stored in the object information storage unit 32 is once read out to the temporary storage unit 40, and the joint surface is read. The vertices belonging to are replaced with predetermined vertices. Particularly, in the present embodiment, the joint surface position coordinate deriving unit 106 is different from the joint movement of the bending angle θ originally performed by the objects A and B with respect to the vertex belonging to the joint surface 100, and the bending angle θ / Three-dimensional coordinate transformation representing the joint motion of 2 is applied. In addition, the position information derivation unit 38 represents the joint motion of the bending angle θ with respect to the vertices other than the vertices belonging to the joint surface 100.
Dimensional coordinate transformation is applied. Then, when the images are combined by the polygons designated by the respective vertices thus derived, the display image already shown in FIG. 15 is obtained.

The three-dimensional game device according to this embodiment succeeds in expanding and contracting a part of the side surfaces of both the object A and the object B by performing such processing, and smoothly connecting the two objects during joint movement. ing.
As a result, it is possible to more naturally display the image of the joint portion than that of the three-dimensional game apparatus according to the first embodiment.

Further, in the three-dimensional game device according to the present embodiment, a joint surface that makes a joint motion having a more gentle bending angle than the joint motion made by the objects A and B is provided in the area between the objects. Therefore, it is possible to display an image of a natural joint portion especially when the joint movement between the objects A and B having a large bending angle is performed.
