BACKGROUND OF THE INVENTION
The present invention relates to a game apparatus and an information storage medium that reduce processing for generating a game image.
[0002]
[Prior art]
Conventionally, in a game device, an image having a given number of frames (for example, 60 frames) is displayed every second, that is, a display screen is updated every given time (for example, 1/60 seconds). Smooth moving images are provided.
[0003]
However, in order to display a more effective and powerful game image or a more realistic game image, an image for one frame can be obtained by precisely setting an object or generating various phenomena and effects. In some cases, the processing time related to generation increases. Therefore, in a conventional game device, when the amount of data related to an image for one frame is large, even if the object is issued, the object is not drawn, so that the data amount is reduced and the processing time is reduced. I was planning.
[0004]

[0031]
DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments of the present invention will be described below with reference to the drawings.
(First embodiment)
FIG. 1 is a diagram showing an example when the present invention is applied to a home game device. In FIG. 1, the user enjoys a given game by operating the game controllers 1202 and 1204 while watching the game image displayed on the display 1200. In this case, information necessary for playing a game such as a game program is stored in a CD-ROM 1206, an IC card 1208, a memory card 1212, and the like, which are information storage media detachable from the main unit.
[0032]
FIG. 2 is a diagram for explaining the principle of the alternate drawing process of the present invention. FIG. 2A shows objects constituting the game space in the scene (scene or stage) in the first frame, FIG. 2B in the second frame, and FIG. 2C in the third frame. In FIG. 2, objects b1 to b6 are set as objects constituting the game space, and object numbers (1 to 6) are assigned to the respective objects.
[0033]
In FIG. 2, for example, object numbers 1, 3, 5 (that is, objects b1, b3, b5) are grouped as group A, and object numbers 2, 4, 6 (that is, objects b2, b4, The case where b6) is classified as group B is shown. Then, the group to be issued for each frame is alternately changed. Here, issuing means generating and arranging objects in the game space. That is, among the issued objects, an object within the visual field range of the virtual camera is drawn as a game image.
[0034]
For example, as shown in FIG. 2A, the object of group A is issued in the first frame, and the object of group B is not issued (indicated by a broken line in the figure). Then, among the issued objects b1, b3, and b5, an object b1 in the range of the visual field (visible region) of the virtual camera (the range indicated by the thick line 7 in the figure) (in the case of FIG. 2A, the object b1) , B3) are drawn (displayed on the screen of the first frame).
[0035]
In the alternate drawing process, the group B is issued in the second frame in order to alternately change the group to be issued for each frame. Therefore, as shown in FIG. 2B, in the second frame, the objects b2, b4, and b6 are issued, and the objects b1, b3, and b5 (group A) are not issued. Then, among the issued objects, objects (in the case of FIG. 2B, objects b2 and b4) within the range of the visual field of the virtual camera (the range indicated by the thick line 7 in the figure) are drawn.
[0036]
Then, in the third frame, the object of group A is issued again, and the objects b1, b3, and b5 are issued as shown in FIG. In this case, the objects b1, b3, and b5 are drawn (although the object 5 is issued, only a part is drawn by clipping).
[0037]
In this way, by issuing objects alternately for each frame and drawing only the issued objects, it is possible to reduce the processing related to the issue of the objects and the processing related to the drawing. In addition, each object is not drawn continuously because the object issued alternately changes. That is, even if the object is not drawn, it is not drawn only for one frame, but is always drawn in the next frame. Therefore, even if the object is not drawn in the image, if the object is drawn in the frames before and after that, the time for which the image of one frame is displayed is very short (for example, 1/60). Therefore, the player who looks at the screen seems to continue to display the object (not aware that one frame has not been drawn (not displayed)).
[0038]
Therefore, it is possible to reduce the drawing process without notifying the player that the object is not displayed.
[0039]
It should be noted that the objects may be classified not only in the two groups A and B but also in three or more groups, and one of the three or more groups may not be issued in order for each frame. Moreover, it is good also as providing the group always issued among 3 groups or more, and not issuing a group other than the group in order for every flame | frame.
[0040]
FIG. 3 is a block diagram illustrating an example of functional blocks according to the present embodiment. The functional blocks according to the present embodiment include an operation unit 10, a processing unit 200, a display unit 30, and a storage unit 500. Is done.
[0041]
The operation unit 10 includes buttons for inputting instructions for character operations in the game, and the input instruction signals are output to the processing unit 200. Controllers 1202 and 1204 shown in FIG.
[0042]
The processing unit 200 mainly includes a game calculation unit 210 and an image generation unit 230. The game calculation unit 210 sets an object in the game space based on an operation instruction from the operation unit 10 and the game program 510 stored in the storage unit 500 (determining the position, rotation, movement amount, size, etc. of the object). Physics operation processing, etc.), processing for setting a virtual camera, processing for determining a rendering processing method for each scene in accordance with rendering processing method data 520, and the like. In addition, the game calculation unit 210 performs light source processing (processing for determining whether there is an influence of light on the object), LOD processing (processing for setting the degree of precision of the object), billboard processing (plate polygon) for the issued object. Preprocessing for drawing, such as processing for confronting the image to the viewpoint.
[0043]
FIG. 4 is a diagram illustrating an example of a data configuration of the drawing processing method data 520. As illustrated in FIG. As shown in FIG. 4, a drawing processing method for each scene of the game is set. For example, “normal” (that is, normal drawing processing) is set for the scene 1. The normal drawing process means that all objects are drawn (issued). That is, it is set for a scene with a light processing load such as a small number of objects constituting the game space in the scene. For scene 2, “alternate” (that is, alternate drawing processing) is set. As shown in FIG. 2, the alternate drawing process means that an object is alternately issued and drawn for each frame. That is, it means that some of the objects that make up the game space in the scene are not drawn.
[0044]
Further, the game calculation unit 210 includes an object issuing unit 212, a drawing object determining unit 214, and a group changing unit 216. The drawing object determination unit 214 determines a group to be issued for each frame, and stores the determined group in the issue group data 602. Specifically, in the case of normal drawing processing, all groups are set as issuing groups. In the alternate drawing process, the objects in groups A and B are alternately set as issue groups for each frame, and the objects in group C are always set as issue groups. That is, the groups A and C and the groups B and C are alternately stored in the issue group data 602 for each frame.
[0045]
FIG. 5 is a diagram illustrating an example of the data configuration of the issue group data 602. As shown in the figure, for example, groups A and C are stored as issue groups in the current frame.
[0046]
In addition, the drawing object determination unit 214 performs processing for determining an object to be issued based on the issue group data 602 and the group classification data 532 and generating skip data 604.
[0047]
FIG. 6 is a diagram illustrating an example of the data configuration of the group classification data 532. As shown in FIG. 6, a priority order and a group are set for the object number of each object. “1” or “2” is set as the priority order. The priority “1” is set for the object number of an object that should always be issued, such as a player character. In other words, “1” is set as the priority for important objects. A group that is always issued (for example, group C) is set as the group for the object number with the priority “1”. In addition, for the object number of the object having the priority “2”, one of two groups, for example, group A or B is set because it is alternately issued for each frame in the alternate drawing process.
[0048]
FIG. 7 is a diagram illustrating an example of the data configuration of the skip data 604. As shown in FIG. 7, in the skip data 604, a skip flag is set for the object number. That is, the drawing object determination unit 214 determines an object to be issued, and performs processing for setting a skip flag for each object number based on the determination. When not skipping (processing is omitted), that is, when issuing, the skip flag is set to “0”, and when skipping, that is, when not issuing, the skip flag is set to “1”.
[0049]
The group changing unit 216 changes the priority set in the group classification data 532 according to the game situation and performs a process of changing the group based on the priority. For example, in FIG. 6, a group A is set for the object number 1, but a scene (frame) in which the object of the object number 1 is important in the game (for example, the object b1 is a number of enemy characters). In the case of a single character, it is usually not important, but when the player character is shot, it becomes important in the shot scene.) In this case, the group changing unit 216 gives priority to the object number 1 The order is changed from “2” to “1”, and accordingly, the group is changed to “C”. That is, even if the drawing processing method is a scene of alternating drawing processing, drawing is always performed.
[0050]
Note that the data of the group classification data 532 is set in advance, and may be fixed data without changing according to the game situation. In addition to the two priorities of “1” and “2”, for example, those that are always issued in the alternate drawing process, those that are not issued once every two frames (alternately), those that are issued in three frames It is also possible to set more ranks, such as those that are not issued once, and classify them into more groups based on the priority order.
[0051]
The object issuing unit 212 issues an object that is determined to be issued (the skip flag is set to “0”), and among these, the image generating unit 230 for an object within the visual field range of the virtual camera. To draw.
[0052]
The image generation unit 230 performs processing (drawing processing) for generating an image viewed from a given virtual camera in the game space. At that time, the object issuing unit 212 draws only the issued object.
[0053]

[0055]
In addition to the game program 510, the storage unit 500 stores object data 530, the above-described drawing processing method data 520, issue group data 602, and skip data 604. The game program 510 includes an image generation processing program 512 that is a program related to image generation processing described later. The object data 530 is data related to various objects set in the game space, and includes the group classification data 532 described above. The functions of the storage unit 500 can be realized by hardware such as a CD-ROM, game cassette, IC card, MO, FD, DVD, hard disk, and memory. As described above, the processing unit 200 performs various processes based on programs, data, and the like stored in the storage unit 500.

In the case of the alternate drawing process, the group changing unit 216 determines the priority order of each object based on the current game situation and sets the group based on the priority order (step S12). Then, the drawing object determination unit 214 determines a group to be issued in the current frame (step S13).
[0058]
In step S13, the object issuing unit 212 issues an object belonging to the group to be issued (step S14). Then, the image generation unit 230 performs a drawing process on an object within the visual field range of the virtual camera among the issued objects, and generates a game image (step S15).
[0059]
Next, it is determined whether or not the scene has been changed (step S19). If there is, the process returns to step S11 to determine whether or not the scene is an alternate drawing process. If the scene has not been changed, the process from step S12 to S15 is performed on the next frame.
[0060]
On the other hand, if it is not the alternate drawing process in step S11, that is, in the case of the normal drawing process, the drawing object determination unit 214 sets all objects as issue objects (step S16). Then, the object issuing unit 212 issues all the objects (step S17), and the image generating unit 230 performs a drawing process on the objects within the visual field range of the virtual camera to generate an image. (Step S18), it is determined whether or not there is a scene change (Step S19).

FIG. 12 is a diagram for explaining the processing time. First, the game calculation unit 210 performs game calculation processing (game space setting processing) in the first frame, determines an object to be issued, performs preprocessing for drawing the issued object, and issues the object ( (1)). After that, only for the objects issued by the image generation unit 230, rendering processing (two-dimensional conversion (perspective projection conversion) processing, attributes (color, shape, etc.) of each object stored in the object data 530 are performed. ), A game image for the first frame is generated ((2)).
[0077]
Then, as shown in FIG. 12, the processing of the game calculation unit 210 and the processing of the image generation unit 230 are performed in parallel, so the processing ((2)) for the first frame by the image generation unit 230 is completed. Even if not, the game calculation unit 210 starts processing for the next frame (second frame) ((3)).
[0078]
Then, the processing time monitoring unit 218 of the game calculation unit 210 measures the processing time of the process (3) for the current frame (second frame) by the game calculation unit 210 during the processing of the second frame. It is determined whether or not the time has exceeded the threshold, and the processing time (2) for the first frame of the image generation unit 230 is measured to determine whether or not the threshold has been exceeded.
[0079]
The drawing object determination unit 214 changes the issuance group data 602 for each frame, as in the case of the alternate drawing process in the first embodiment. Then, the drawing object determination unit 214 sets the currently processed object as an object to be issued when the threshold is not exceeded in the current frame. For objects to be processed after the threshold, whether or not to issue the object currently processed is determined by referring to the issue group data 602 for the current frame and the group classification data 532. Specifically, in the skip data 604, a skip flag for an object that is not issued is set to “1”.
[0080]
The image generation unit 230 performs the same processing as in the first embodiment. The counter 240 measures the current count and outputs a count signal to the processing time monitoring unit 218 as needed.
[0081]
Next, the operation related to the load monitoring process in the second embodiment will be described based on the flowchart shown in FIG. Note that the operation shown in FIG. 13 is an operation related to a one-frame load monitoring process.
[0082]
First, the game calculation unit 210 determines whether or not all the objects included in the game space have been processed in the currently processed frame (step S21). If all of the objects have been processed, the process ends. To do. If there is an object that has not yet been processed, the drawing object determination unit 214 sets the skip flag for that object to “0” in the skip data 604 after identifying one object among the unprocessed objects. (Step S22). Then, the processing time monitoring unit 218 determines whether or not the processing time of the game calculation unit 210 has exceeded a threshold value (step S23).
[0083]
If it exceeds the threshold, the process proceeds to step S25. If the threshold is not exceeded, the processing time monitoring unit 218 determines whether or not the processing time of the processing performed by the image generation unit 230 for the previous frame has exceeded the threshold (step S24). If exceeded, the process proceeds to step S25. If not, the game calculation unit 210 performs preprocessing for drawing on the object currently being processed (step S27), and proceeds to step S28.
[0084]
In step S25, the drawing object determination unit 214 refers to the issue group data 602 and the group classification data 532, and the object currently being processed belongs to a group that may be skipped (not set in the issue group data 602). It is determined whether or not. If it belongs to the group that can be skipped, the drawing object determination unit 214 sets the skip flag for the object currently being processed in the skip data 604 to “1” (step S26), and proceeds to step S28.
[0085]
In step S25, in the case where the object does not belong to the group that can be skipped, the game calculation unit 210 performs the preprocessing for drawing to the object currently being processed when the object is within the visual field range of the virtual camera. On the other hand, preprocessing for drawing is executed (step S27), and the process proceeds to step S28.
[0086]
In step S28, the game calculation unit 210 performs a physics calculation on the object, and sets the object in the game space. Then, the object issuing unit 212 determines whether or not the skip flag for the object currently being processed is “1” (step S29). If it is not “1”, the object is issued and “1” is issued. If there is, the process returns to step S21 without issuing the object.
[0087]
As a hardware configuration capable of realizing the second embodiment, the current count is further counted in the hardware configuration in the first embodiment shown in FIG. 9, and the counted count is output. Therefore, the counter circuit is connected to the system bus 1016.
[0088]
As described above, according to the present invention, an object to be issued can be determined according to the processing load related to image generation, that is, a part of the object can be prevented from being issued. It is possible to reduce the processing time.
[0089]
The load monitoring process in the second embodiment may be performed for each frame, but is performed only for the first frame of the scene. As a result, if the processing time exceeds the threshold, the scene Subsequent frames may be subjected to the alternate drawing process in the first embodiment. In that case, the drawing processing method data 520 is set according to the processing time for the first frame of the scene.
[0090]
【The invention's effect】
According to the present invention, in a scene in which an issue object is restricted, issue of an object constituting the scene is suppressed. Or according to the processing load which concerns on the production | generation of a game image, issue of the object which comprises a scene can be suppressed and a drawing process load can be reduced. Furthermore, since the issue is not performed for an object that is not drawn, it is possible to more efficiently reduce the processing related to the generation of the game image.
