The three-dimensional information processing unit 24 performs so-called geometry calculation processing to generate projection information that is two-dimensional coordinate information obtained by projecting an object in the world coordinate system onto a projection plane based on the viewpoint. Further, the projection information is provided to the image generation processing unit 26.
The image generation processing unit 26 is instructed to generate a display image based on the projection information. In addition,
The three-dimensional information processing unit 24 corresponds to the auxiliary object setting means, the viewpoint setting means, and the identification object setting means in the present invention.

The texture storage unit 25 is a memory for storing a texture which is image information of the pattern of the object. The texture storage unit 25 stores an identification pattern which is an image attached to an identification object projected on a projection plane and an auxiliary pattern which is an image attached to an auxiliary object. The identification symbol and the auxiliary symbol are appropriately read by the image generation processing unit 26.

The image generation processing unit 26 is an image data processor that generates a display image to be displayed on the liquid crystal monitor 4. The image generation processing unit 26 is a three-dimensional information processing unit 24.
On the basis of the projection information given from the above, addresses corresponding to the vertices of each polygon of each object in the frame buffer provided in the image storage unit 27 are obtained. Further, the image generation processing unit 26 deforms the texture read from the texture storage unit 25 so as to match the vertices of each polygon of each object, and draws the texture based on each address in the frame buffer. When the drawing of textures on all objects is completed, a display image is generated in the frame buffer of the image storage unit 27. The image generation processing unit 26 corresponds to the image generation means in the present invention.

The image storage unit 27 is a video memory provided with a frame buffer (not shown) for storing a display image which is an image for one screen generated by the image generation processing unit 26. For example, the image storage unit 27 is provided with at least two frame buffers in which the image generation processing unit 26 alternately generates display images. The image generation processing unit 26 generates a display image in one frame buffer and outputs the display image in the other frame buffer to the liquid crystal monitor 4, thereby realizing a three-dimensional display mode with less dropped frames.

The liquid crystal monitor 4 is provided with a display screen 4a for displaying the display image output from the image generation processing section 26, and the display screen 4a is attached so as to be exposed on the board surface of the game board 7. The liquid crystal monitor 4 corresponds to the display means in the present invention.

On the display screen of the liquid crystal monitor 4 described above, based on the command sent from the control board 1, for example, the display mode in the normal fluctuation as shown in FIG. 4 is displayed. As shown in FIG. 4, on the display screen 4a, an identification symbol B in which a symbol number for the player to identify the game state is drawn
1 to B3 are displayed so as to scroll laterally at independent speeds, respectively, and their identification symbols B1 to B3 are displayed.
On the back side of B3, the auxiliary symbol C is displayed so as to change regardless of the scroll of the identification symbols B1 to B3. Here, the identification symbol B1 is an identification symbol that scrolls in the upper part of the display screen 4a, the identification symbol B2 is an identification symbol that scrolls in the middle of the display screen 4a, and the identification symbol B3 is a display screen 4a.
Each of the identification patterns scrolled at the bottom of the. Specifically, as shown in FIG. 4A, in the initial state, the identification symbols S1 to S3 are lined up, for example, in an oblique straight line and stopped. Then, as shown in FIGS. 4B and 4C, the stopped identification symbols B1 to B3 start scrolling laterally at their respective speeds. When a predetermined time elapses in a state where each of the identification symbols B1 to B3 is scrolled, FIG.
As shown in (d), they are aligned vertically and stopped again. Irrespective of the scrolling of these identification symbols B1 to B3, the auxiliary symbol C on the back side of the identification symbols B1 to B3 is displayed on the display screen 4a so that the angle at which the auxiliary symbol C is viewed gradually changes. In addition, when the identification symbols B1 to B3 arranged in a straight line are symbols of the same type (for example, the same symbol number), a big hit occurs, and a display mode for the big hit is displayed. On the other hand, when the symbols are not of the same type, the normal fluctuation is continued, and the display modes similar to those in FIGS. 4A to 4D are repeatedly displayed. The player grasps the above-mentioned gaming state occurring in the gaming machine by identifying the types of the identification symbols B1 to B3 stopped side by side.

The processing performed by the image display device 2 based on the command sent from the control board 1 in order to realize the above-described display mode will be described with reference to the flowchart shown in FIG.

Step T1 (Grasping of command) The interface 21 sequentially receives the commands sent from the control board 1 and sequentially passes the commands to the three-dimensional information processing unit 24. The three-dimensional information processing unit 24 stores the command in the command buffer. Further, when there is an interrupt process from the liquid crystal monitor 4, the three-dimensional information processing unit 24 selects a program corresponding to the command stored in the command buffer from the program storage unit 23 and executes the program. By the execution of the program, the three-dimensional information processing unit 24 and the image generation processing unit 26 execute the following steps to realize the display mode shown in FIG.

Step T2 (setting auxiliary object) As shown in FIG. 6, first, the three-dimensional information processing unit 24
A world coordinate system corresponding to a virtual three-dimensional coordinate space for setting a plurality of objects that are dimension information is set. Next, the three-dimensional information processing unit 24 reads the auxiliary object OC corresponding to the auxiliary symbol C (see FIG. 4) displayed on the display screen 4a from the object storage unit 22 and sets the auxiliary object OC in the world coordinate system. . The setting of the auxiliary object OC is performed by determining the posture of the auxiliary object OC when the auxiliary object OC is arranged in the world coordinate system and the position to be arranged in the world coordinate system.

The posture of the auxiliary object OC is determined by rotating the posture of the object stored in the object storage unit 22 according to the rotation amount derived by the program for each interrupt process. For example, the posture of the auxiliary object OC can be rotated by deriving a new rotation amount each time step T2 is executed. In this embodiment, the auxiliary object OC
In order to bring the posture of No. 1 into a stationary state, the same amount of rotation amount, for example, “0 °” is derived for each interrupt process.

The position at which the auxiliary object OC is arranged is determined by the coordinate value based on the origin of the world coordinate system derived by the program for each interrupt processing. For example, by deriving a new coordinate value each time step T2 is executed, the auxiliary object OC
Can be moved arbitrarily in the world coordinate system.
In this embodiment, the coordinate value of the coordinate point P1 is derived for each interrupt process in order to bring the auxiliary object OC into a stationary state.

The three-dimensional information processing unit 24 rotates the read posture of the auxiliary object OC based on the rotation amount,
The auxiliary object OC after the rotation is set at the coordinate point P1 in the world coordinate system based on the coordinate value to set the auxiliary object OC in the world coordinate system. The three-dimensional information processing unit 24 sets the auxiliary object OC in the world coordinate system, so that the auxiliary object O
The coordinate value of each vertex of each polygon forming C is converted into the coordinate value of the world coordinate system. The step T2 corresponds to the function of the auxiliary object setting means in the present invention.

Step T3 (set viewpoint) The three-dimensional information processing unit 24 sets the viewpoint SP in the world coordinate system for displaying the state in the predetermined space in the world coordinate system on the display screen 4a of the liquid crystal monitor 4. To do. As shown in FIG. 6, this viewpoint SP is a reference point of a coordinate system having a line of sight that points in a predetermined space in the world coordinate system as the z axis. The predetermined space refers to a virtual space included in the visual field range of the line of sight.

Specifically, the three-dimensional information processing section 24 sets the viewpoint SP based on the coordinate values in the world coordinate system derived by the program, and at the same time, the viewpoint SP.
The eye gaze is rotated in an arbitrary direction, for example, the direction in which the object is arranged, based on the rotation amount of the eye gaze derived for each interrupt process. In this embodiment, the three-dimensional information processing unit 24 changes the viewpoint SP from the coordinate point P2 to the coordinate point P3 in the world coordinate system for each interrupt process.
Coordinate values on a locus that draws an arc (indicated by a chain line arrow in the drawing) are derived, and a rotation amount of the line of sight such that the line of sight of the viewpoint SP on the locus faces the auxiliary object OC is derived. As a result, the three-dimensional information processing unit 24 causes the step T
Each time 3 is executed for each interrupt process, the coordinate value of the viewpoint SP and the rotation amount of the line of sight are sequentially updated so that the line of sight faces the auxiliary object OC and draws an arc from the coordinate point P2 to the coordinate point P3. The viewpoint SP to be displaced is set.
Further, every time the three-dimensional information processing unit 24 executes step T3, as shown in FIG. 7, the coordinate values of the vertices of the polygons of the auxiliary object OC set in the world coordinate system are set to the world coordinate system. It is converted into a coordinate value in the viewpoint coordinate system with the viewpoint SP set to 1. The step T3 corresponds to the functions of the viewpoint setting means and the viewpoint displacing means in the present invention.

Step T4 (set identification object) The three-dimensional information processing section 24 identifies objects OB1 to OB3 (FIG. 3) which are three-dimensional information corresponding to the identification symbols B1 to B3 (see FIG. 4) displayed on the display screen 4a. 7, see Fig. 8)
Is read from the object storage unit 22. Further, the three-dimensional information processing unit 24 uses the identification objects OB1 to OB.
In order to set 3 between the viewpoint in the viewpoint coordinate system and the auxiliary object OC, the postures of the identification objects OB1 to OB3 when arranging in the viewpoint coordinate system and the positions to be arranged in the viewpoint coordinate system are determined.

The postures of the identification objects OB1 to OB3 are determined by rotating the postures of the objects stored in the object storage unit 22 according to the rotation amount derived by the program for each interrupt process. For example, by deriving a new rotation amount each time step T4 is executed, the identification objects OB1 to OB
The postures of B3 can be rotated respectively. In addition,
In the present embodiment, since the postures of the identification objects OB1 to OB3 are not rotated, the same rotation amount, for example, “0” is derived for each interrupt process. Also, each identification object O
The identification objects OB1 to OB3 are displayed such that, for example, a design number, which is an identification pattern displayed by the texture attached to B1 to OB3, is always displayed in front.
Is set to be perpendicular to the viewing direction from the viewpoint SP or the projection plane TM.

The positions at which the identification objects OB1 to OB3 are arranged are determined by coordinate values with respect to the viewpoint SP which is the origin of the viewpoint coordinate system derived by the program for each interrupt process. As shown in FIG.
The dimension information processing unit 24 sequentially derives coordinate values of coordinate points such that each of the identification objects OB1 to OB3 moves laterally in the line-of-sight direction side for each interrupt process, for example, every time step T4 is executed. By arranging the identification objects OB1 to OB3 at the coordinate points of the coordinate values that are sequentially derived, the arrangement position is sequentially updated for each interrupt process, and the identification objects OB1 to OB1 in the viewpoint coordinate system.
OB3 is moved laterally. At this time, if different coordinate values are derived for each of the identification objects OB1 to OB3, the identification objects OB1 to OB3 can be displayed so as to move laterally at different speeds. Further, as shown in FIG. 9 which is a state viewed perpendicularly to the x-axis of the viewpoint coordinate system, the z value at the coordinate value of the coordinate points at which the sequentially derived identification objects OB1 to OB3 are arranged is the viewpoint SP, that is, It is a value between the origin and the z value in the coordinate value of the coordinate point Px that is closest to the viewpoint SP among the coordinate points included in the auxiliary object OC. As a result, the identification objects OB1 to OB3 are moved to the viewpoint S
It is set in the virtual space between P and the auxiliary object OC. That is, in step T4, the identification objects OB1 to OB3 are set with the viewpoint SP as a reference, so that the identification objects OB1 to OB3 are changed on the line of sight side independently of the displacement of the viewpoint SP set in step T3. Can be made. The step T4 corresponds to the function of the identification object setting means in the present invention.

Step T5 (project to projection plane) The three-dimensional information processing unit 24 sets a projection plane for projecting a state in the visual field range from the viewpoint SP in the line-of-sight direction, and the projection plane includes identification included in the visual field range. Objects OB1 to O
B3 and the auxiliary object OC are projected for each interrupt process.

Specifically, as shown in FIG. 7 to FIG.
The three-dimensional information processing unit 24 determines the viewpoint SP and the identification object O.
A projection plane TM perpendicular to the z axis in the viewpoint coordinate system is set between B1 and OB3. Since the projection plane TM is perpendicular to the z axis of the viewpoint coordinate system and the z value is fixed, it can be treated as a two-dimensional coordinate system on the projection plane TM. The projection plane TM has an area corresponding to the frame memory provided in the image storage unit 27.

Further, the three-dimensional information processing unit 24 is shown in FIG.
As shown in (a), the identification objects OB1 to OB3 are projected in parallel onto the projection plane TM. As a result, the vertices of the polygons that form the identification objects OB1 to OB3 are projected as they are so as to move in parallel to the projection plane TM, and the three-dimensional coordinate values of each vertex are 2 on the projection plane TM.
Converted to dimension coordinate values. Also, the three-dimensional information processing unit 2
As shown in FIG. 10B, 4 perspectively projects the auxiliary object OC set on the back side of the identification objects OB1 to OB3 on the projection plane TM. As a result, the vertices of each polygon forming the auxiliary object OC are projected so as to move in the viewpoint SP direction, and the three-dimensional coordinate values of each vertex are converted into two-dimensional coordinate values on the projection plane TM. When the projection of all objects within the field of view ends, the three-dimensional information processing unit 24 uses the two-dimensional coordinate values of each vertex on the projection plane TM as projection information and the image generation processing unit 26.
Send to. Note that step T6 corresponds to the functions of the projection plane setting means and the projection means.

Here, the above-mentioned identification object OB1
In order to facilitate understanding of the effects of perspective projection of OB3 and perspective projection of the auxiliary object OC,
A specific example will be described. For example, as shown in FIG. 11, cube-shaped identification objects OBa and OBb are set side by side in the world coordinate system at intervals, and the viewpoint is oriented so that the line of sight is oriented substantially at the center between the identification objects OBa and OBb. Set SP. In this case, when a projection plane (not shown) based on the viewpoint SP is set and the identification objects OBa and OBb are perspective-projected onto this projection plane, as shown in FIG.
Identification symbols Ba and Bb corresponding to Ba and OBb are displayed with a space left and right in the display screen 4a. Figure 12 (a)
As is apparent from the identification pattern Ba, the front number "1", the top number "2", and the right side number "3" are displayed, while the identification pattern Bb has the front number "3". 1 "
And the number "2" on the top and the number "4" on the right. As a result, the identification patterns Ba and Bb, which should be the same identification patterns for the player to identify, are displayed in different patterns, which causes a problem of difficulty in identification. Therefore, as described in this step, by projecting the identification objects OBa and OBb in parallel, as shown in FIG. 12B, the same identification pattern is displayed so as to have the same pattern. There is an effect that the player can easily identify the identification pattern. Further, since the auxiliary objects other than the identification object are perspectively projected, they are three-dimensionally displayed on the display screen 4a based on the viewpoint. As a result, a realistic display mode is displayed on the display screen.

Step T6 (Generate display image) The image generation processing unit 26 is in the frame buffer of the image storage unit 27 corresponding to the coordinate value of each vertex included in the projection information sent from the three-dimensional information processing unit 24. Position, that is, the address is obtained. Then, the image generation processing unit 26 reads out the texture from the texture storage unit 25. At this time, the texture to be attached to each polygon of the object is read in the order of the object set at the position far from the viewpoint SP. This texture is, for example, an image in which a number indicating a so-called pattern number in a pachinko machine is drawn as shown in FIG. The read texture is transformed according to the shape of the polygon to which the texture is attached, and the texture is drawn at the corresponding address in the frame buffer. When all polygons in the frame buffer have been drawn,
In the frame buffer of the image storage unit 27, the display screen 4
A display image to be displayed on a is generated. The image generation processing unit 26 sends the display image generated in the frame buffer of the image storage unit 27 to the liquid crystal monitor 4 for each interrupt process. The step T6 corresponds to the function of the image generating means in the present invention.

Step T7 (Display) The liquid crystal monitor 4 displays the image generation processing unit 2 for each interrupt processing.
By sequentially displaying the display images sent from 6, the display mode as shown in FIG. 4 is displayed.

According to the pachinko machine described above, since the auxiliary design based on the three-dimensional information is not displayed on the front surface of the identification design based on the three-dimensional information, the identification design can be always displayed in an easily distinguishable manner. Further, since the identification object is set in the viewpoint coordinate system based on the viewpoint, even if the same coordinate value is always given to the identification object, the identification pattern displayed on the display screen 4a is moved along with the displacement of the viewpoint. Can be made. As a result, it is not necessary to set the identification object in consideration of the displacement of the viewpoint, so that the processing can be reduced. Furthermore, since the object which is the three-dimensional information corresponding to the identification pattern is projected in parallel, it is displayed in the same manner regardless of where it is displayed on the display screen, which makes it easier for the player to identify.

In step T4 of the above-described embodiment, the identification object is set to the coordinate point having the coordinate value with respect to the viewpoint, that is, the viewpoint coordinate system. For example, the coordinate value with respect to the origin of the world coordinate system is set. It can also be configured to set to a coordinate point having

In step T4 of the above-described embodiment, the identification object in the viewpoint coordinate system is moved in the horizontal direction so that the identification pattern displayed on the display screen moves in the horizontal direction. It is also possible to set the identification object in the viewpoint coordinate system to move vertically or diagonally so that the identification pattern displayed on the display screen moves vertically or diagonally.
Furthermore, the identification object in the viewpoint coordinate system is moved from the auxiliary object side to the viewpoint side, or the viewpoint side, so that the identification pattern displayed on the display screen moves from the back side to the front side or from the front side to the back side of the display screen. It is also possible to set to move from to the auxiliary object side.

In the above-described embodiment, the identification object corresponding to the identification pattern is described as a three-dimensional spherical object, but the identification pattern can be displayed by a so-called plane polygon, for example. In this case, the plane polygon is set to face the direction of the line of sight from the viewpoint SP or the projection plane TM.

In the above-described embodiment, the identification pattern in which a so-called symbol number is drawn as the identification pattern has been described.
The present invention is not limited to such a symbol number, and can be applied as an identification symbol as long as it is a symbol that allows the player to identify the game state. In this case, the object corresponding to the symbol number is set so that the symbol number always faces the display screen.

Although the liquid crystal monitor has been described in the above embodiment, for example, a CR is used instead of the liquid crystal monitor.
It may be a T monitor, an LED monitor, or the like.

Further, in the above-mentioned embodiment, the pachinko machine was explained as the game machine, but the present invention is not limited to this, and for example, a slot machine, a coin game machine, an arcade game machine, a home video game machine. It can be modified and implemented in various game machines such as.

[0068]

As is apparent from the above description, according to the present invention, the identification object corresponding to the identification symbol is set closer to the viewpoint than the auxiliary object corresponding to the auxiliary symbol, so that the game state is identified. The identification pattern for doing can be displayed on the foreground of the display screen. As a result, the player can be made to accurately grasp the identification pattern, so that the player's interest can be maintained.
