Here, the form of the above-mentioned game system differs depending on the use. That is, the game system
When configured for home use, the television monitor 12 and the speaker 16 are separate from the game machine body. When the game system is configured for business use, all the components shown in FIG. 1 are housed in one integrated housing. When the game system is configured with a personal computer or a workstation as a core, the television monitor 12 corresponds to a display for the computer, and the drawing processor 10, the audio processor 13, The expansion circuit 7 corresponds to a part of the game program data recorded on the recording medium 30 or hardware on an expansion board mounted on an expansion slot of a computer.

The buffers 11, 14 and 18 respectively correspond to areas of the main memory 5 or an extended memory (not shown). In the present embodiment, a case where the game system is configured for home use will be described as an example.

Next, each component shown in FIG. 1 will be described in more detail. The graphics data generation processor 3 plays a role as a so-called coprocessor of the CPU 1. That is, the graphics data generation processor 3 performs coordinate conversion and light source calculation, for example, calculation of a fixed-point format matrix or vector by parallel processing. The main processing of the graphics data generation processor 3 is a coordinate conversion processing and a light source calculation processing. The coordinate transformation process

Transform processing, intra-image restoration processing, and the like.

The drawing processor 10 performs drawing processing on the buffer 11 based on a drawing command issued by the CPU 1. The buffer 11 includes a drawing area in which stored image data is displayed, and a texture area in which image data to be written in the drawing area is held. The drawing area is an area for developing data displayed on the display surface of the television monitor 12. The texture area is a storage area for texture data, color palette data, and the like. Here, the texture data is two-dimensional image data. The color pallet data is data for specifying a color such as texture data. These data are read out by the CPU 1 once from the recording medium 30 or divided into a plurality of times according to the progress of the game.
It is stored in the texture area of the buffer 11 in advance.

The drawing commands include, for example, a drawing command for drawing a line, a drawing command for drawing a three-dimensional image using polygons, and a drawing command for drawing a normal two-dimensional image. Here, the polygon is a polygon 2
This is a three-dimensional image, and in the present embodiment, a triangle or a quadrangle is used.

A drawing command for drawing a line is composed of a line drawing start and end address, a color, and data indicating a line drawing. This line drawing command is executed by the CPU
1 is issued directly to the drawing processor 10.

A drawing command for drawing a three-dimensional image using polygons includes polygon vertex address data in the drawing area of the buffer 11 and texture address data indicating the storage position in the buffer 11 of the texture data to be attached to the polygon. , Color pallet address data indicating the storage position of the color pallet data indicating the color of the texture data on the buffer 11, and luminance data indicating the luminance of the texture. Among these data, the polygon vertex address data is calculated by the graphics data generation processor 3 based on the polygon absolute coordinate data, the data indicating the movement of the polygon, and the data indicating the movement of the viewpoint position from the CPU 1. Is obtained. Here, how the polygon vertex address data is obtained will be described.

The movement of an object on the display surface of the television monitor 12 is determined by the movement of the object itself and the movement of the viewpoint with respect to the object. For example, if only the object moves and the viewpoint position is fixed, the movement of the object on the display surface of the television monitor 12 is the movement of the object itself. Conversely, if the object does not move and only the viewpoint position is moved, the movement on the display surface of the television monitor 12 is the movement of the viewpoint position itself. Note that it will be easier to understand if the “viewpoint position” is read as “camera position”. In other words, on the display surface of the television monitor 12,
A display as if an image of an object was taken while moving the camera is performed. For the sake of simplicity, the case where either the object or the viewpoint position moves has been described. However, normally, processing is performed as if both the object and the viewpoint position are moving, and the result is displayed.

Here, the "movement" of the object includes "rotation amount" and "movement amount". The rotation amount of the object with respect to the viewpoint position is generated by the rotation angle of the object and the rotation angle of the viewpoint position. Here, the rotation amount and the rotation angle are represented by a 2 × 2 matrix in a process using a two-dimensional coordinate system and a 3 × 3 matrix in a process using a three-dimensional coordinate system. Further, the movement amount of the object with respect to the viewpoint position is generated by the position (coordinate value) of the object, the position (coordinate value) of the viewpoint position, and the rotation angle of the viewpoint position. Here, as described above, the rotation angle is represented by a 2 × 2 matrix in a process using a two-dimensional coordinate system and a 3 × 3 matrix in a process using a three-dimensional coordinate system. Controller 2
The rotation angle of the object and the rotation angle of the viewpoint position based on the operation 2 are:
Each is held as a table. The CPU 1 reads the rotation angle of the corresponding object or viewpoint position from the table based on the operation of the controller 22 and uses the read rotation angle to obtain the rotation amount and the movement amount of the object with respect to the viewpoint position. is there.

As can be seen from the above description, the polygon vertex address data in the drawing area is obtained as follows. That is, the rotation angle and position of the object and the rotation angle and position of the viewpoint position are obtained by the CPU 1 according to the operation of the controller 22. Next, the CPU 1 calculates the amount of rotation of the object with respect to the viewpoint position based on the rotation angle of the object and the rotation angle of the viewpoint position. And CP
U1 determines the amount of movement of the object with respect to the viewpoint based on the position of the object, the position of the viewpoint, and the rotation angle. As described above, the rotation amount and movement amount data of these objects are represented by a 3 × 3 matrix when the processing is performed using the three-dimensional coordinate system.

The rotation amount and movement amount data of the object are provided to the graphics data generation processor 3 together with the absolute coordinate data of the polygon. The graphic data generation processor 3 converts the absolute coordinate data of the polygon into polygon vertex address data based on the rotation amount and movement amount data of the object. The above is the processing until the polygon vertex address data is obtained.

The polygon vertex address data indicates an address on the drawing area of the buffer 11. The drawing processor 10 sets a triangular or quadrangular range indicated by three or four polygon vertex address data in the drawing area of the buffer 11, and writes the corresponding texture data in the range. This process is generally called "pasting texture". As a result, on the display surface of the television monitor 12, an object in which texture data is pasted on a large number of polygons is displayed.

A drawing command for drawing a normal two-dimensional image includes vertex address data, texture address data, color palette address data, and luminance data indicating the luminance of the texture. Among these data, the vertex address data is coordinate data obtained by the graphics data generation processor 3 performing coordinate conversion of vertex coordinate data on a plane from the CPU 1 based on the movement amount data from the CPU 1. . Hereinafter, the drawing process will be described in a simplified manner, such as “issue a drawing command”.

The color information is referred to from the color palette data CP based on the information, and the texture data dt is obtained.
Is added with color information. At this time, the texture data d
The luminance Y, priority, and attribute (transparent, translucent, etc.) of t are also added. Subsequently, an address and area data P (Px, Py, Pw, Ph) indicating the position and size of the texture data dt on the drawing area Ar1 of the buffer 11 are designated by the drawing command issuing means 1m. Then, the drawing processor 10 determines, based on all the above information,
The texture data dt read from the texture area Ar2 of the buffer 11 is written on the drawing area Ar1 of the buffer 11, and the addition of a designated color is performed.
This is the drawing data shown in FIG. 5A with the reference symbol dp. Here, Px is a horizontal address on the drawing area Ar1, Py is a vertical address on the drawing area Ar1, Pw is a width on the drawing area Ar1, and Ph is a height on the drawing area Ar1.

As can be understood from the above description, the normal mapping means that the texture data dt is stored in the texture area Ar.
2 means that the color is read using the color pallet data CP and is written in the drawing area Ar1.

FIG. 6 is an explanatory diagram for explaining the direct mapping. As shown in FIG. 5B,
The texture data dt1 is stored in the texture area Ar2.
Is stored. However, this texture data dt1 is not used in direct mapping.
In this example, the drawing data on the drawing area Ar1 shown in FIG.
1 at a position indicated by P (Px, Py), P (Pw,
Ph). Hereinafter, this drawing data is referred to as texture data dt2. What is important here is that the texture data dt2 in the drawing area Ar1 used as texture data is already colored. In other words, in the case of the direct mapping, the drawing data stored in the drawing area Ar1 is used as it is, so that there is no need to perform a process of referring to the color pallet data CP and coloring.

When displaying the texture data dt2 stored in the drawing area Ar1, the following processing is performed. That is, the texture data dt2 stored in the drawing area Ar1 by the drawing command issuing unit 1m.
Address data T2 (U2V2) is designated. At this time, the color, luminance Y, priority, and attribute (transparent, translucent, etc.) have already been added to the texture data dt2. Subsequently, the address and area data P indicating the position and size of the texture data dt2 on the drawing area Ar1 of the buffer 11 by the drawing command issuing means 1m.
(Px, Py, Pw, Ph) are specified. Then, the drawing processor 10 writes the texture data dt2 read from the drawing area Ar1 of the buffer 11 on the drawing area Ar1 of the buffer 11 based on all the information. The drawing data written in the drawing area Ar1 is
This is the drawing data shown in FIG. 6A with the reference symbol dp. As can be understood from the above description, the direct mapping means that the drawing data of the drawing area Ar1 is regarded as the texture data, the texture data dt2 is read from the drawing area Ar1, and written in the drawing area Ar1.

Here, description will be made again with reference to the flowchart of FIG. When the drawing mode is set to the direct mode, the process proceeds to step S52. In step S52, for example, as shown in FIG. 7, the texture area designating unit 1f sets the drawing area Ar1 as a texture area.
Texture data dt having T3 (U3, V3) as a vertex
Specify 1. In step S53, as shown in FIG. 7, for example, the drawing area designating unit 1g sets the drawing area Ar1
, P3 (x3, y3, w3, h3) is designated. Here, it is assumed that w3 and h3 are specified to be smaller than the area T3. Then, the texture data dt1 is written in the drawing area Ar1 in a size indicated by the width w3 and the height h3. This is the drawing data dp shown in FIG.

In step S54, the luminance specifying means 1h
Specifies the luminance Y. In step S55, the priority designation unit 1i designates a display priority. Here, the priority is a value indicating which image is displayed with priority. Now, as described above, the drawing area Ar
1 is a texture area, and within this area, T
When the region having the vertex 3 as the vertex is specified, P3 (x3, y3, w3, h3) is specified in the drawing region Ar1, and the priority and the luminance are further specified, the drawing processor 10 outputs the information. Based on the buffer 11
The designated image is written at the designated brightness and priority in the drawing area Ar1.

FIG. 8 is a view for explaining a case where, in the frame shown in FIG. 7, the drawing data dp written in the drawing area Ar1 is extracted as texture data of the texture area, and the extracted data is written in the drawing area Ar1. FIG. The drawing area designating means 1g outputs the drawing area A
P4 (x4, y4, w4, h4) in r1 is specified.
Here, it is assumed that w4 and h4 are specified as values smaller than the area T4. Then, the texture data dt2 is written in the drawing area Ar1 in the size indicated by the width w4 and the height h4. This is the drawing data dp shown in FIG. That is, the drawing data dp currently displayed on the television monitor 12 is the texture data dt2 extracted from the drawing area Ar1. Also, the currently displayed texture data dt2
Is the texture data d extracted from the drawing area Ar1
t1.

FIGS. 9 to 11 are views showing display examples that can be expressed by the processing described above. 9 and 10
Is a mirror effect. In FIG.
Past frames are sequentially displayed behind the image V (f) of the current frame. For example, the image V of the current frame
Behind (f) is the image V (f-1) one frame before. This is an effect similar to the visual effect obtained when, for example, an image captured by a television camera is projected on a television monitor, and the television camera captures an image on the tube surface of the television monitor. Naturally, the priority value is the highest for the image V (f) of the current frame. This example will be described below with reference to FIG. That is, for example, dp is the image of the current frame, dt1 is the image of one frame before, and dt2 is the image of two frames before. In FIG. 10, images of past frames are sequentially displayed behind the female character C1 and the male character C2. Assuming that the images of the female character C1 and the male character C2 are images of the current frame f, the image of the character displayed behind one of these characters is the image one frame before and further behind these images. Is an image two frames before. For example, the image immediately after the female character C1 and the male character C2 is one frame before,
This is an image written and displayed in the drawing area Ar1 of the buffer 11, and the image is extracted as texture data as it is, and in the current frame, the drawing area A
r1. Of course, the priority value of the female character C1 and the male character C2, which is the image of the current frame, is the highest. When the values between T3 and P3 and between T4 and P4 shown in FIGS. 7 and 8 are increased, as shown in FIGS. 9 and 10, the image of the past frame is separated from the image of the current frame. Is displayed. FIG. 11 has the same display principle as FIGS. 9 and 10, except that the luminance Y
Is specified. In addition, T3 and P3 shown in FIGS.
3, and the distance between T4 and P4 is short. Therefore, as shown in FIG. 11, a past frame is displayed like a shadow of the female character C1 and the male character C2, which is an image of the current frame. For example, when only red is emphasized, the luminance has the following set value. B (R (red), G (green), B (blue)) = B (8
0, 20, 20) The images of the past frames in FIGS. 9, 10, and 11 all follow the movement of the female character C1 and the male character C2, which are the images of the current frame.

Next, with reference to the flow chart of FIG. 12, the processing for realizing the multi-screen expression in the display routine shown in FIG. 3 will be described. Here, the “multi-screen” refers to the image of the currently displayed frame,
This means that many images obtained by reducing the image of this frame are displayed.

In step S101, the texture area specifying means 1f specifies the drawing data in the drawing area Ar1 as texture data. As described above, the designation is performed by designating the horizontal address, the vertical address, the width, and the height. Step S102
Then, the variable setting means 1d sets the drawing mode to the direct mapping mode.

In step S103, the drawing area specifying means 1g specifies the drawing position and the drawing size of the texture data in the drawing area Ar1. here,
The position is P (Px, Py) and the size is P (Pw, P
y). In step S104, the priority specifying means 1i specifies the priority of the texture data.

In step S105, the luminance specifying means 1h
Specifies the luminance Y of the texture data. In step S106, the determining means 1c determines whether or not the position and the size have been designated by the number to be displayed in the drawing area Ar1, and if "YES", the process exits this routine and "NO". ", The process returns to step S102. In the example of FIG. 13, the number to be displayed is “15”.
It is.

FIG. 13 is an explanatory diagram for explaining the above processing. As shown in FIG. 13, the image in the drawing area Ar1 is used as texture data by an address T3 (U3, V3
Specified in 3). This data is used as texture data. Subsequently, the drawing area designating means 1g sets P1
(X1, y1, w1, h1), P2 (x2, y2, w
2, h2),..., P15 (x15, y15, w1)
5, h15). As a result, as shown in FIG. 13, image data having the same contents as the drawing data specified by the address T3 (U3, V3) is used as drawing data as P1 (x1, y1), P2 (x2, y2), ...
・ P1 is placed at the position indicated by P15 (x15, y15).
(W1, h1), P2 (w2, y2),..., P15
The data is written with the size indicated by (w15, h15), and the priority and the luminance Y are specified. At this time, the luminance Y of the image forming the multi-screen is, for example, R,
By displaying B in a bluish state by setting B to a high value out of G and B, it is possible to produce a monitor-like effect.

FIG. 14 is a diagram showing a display example of the multi-screen. In this figure, a male character C2 is selected, and a reduced image of the male character C2 is displayed as the background of the female character C1 and the male character C2. Of course, the priority value is such that the value of the female character C1 and the value of the male character C2 are higher than the value of the background image.

Next, referring to FIGS. 15 and 16, FIG.
