Description

  The present invention relates to an image generation device, a game machine, and a program.

In game machines and game machines, image production using a display device is an important element for making a player feel a sense of expectation and thrill of a big hit. In particular, in order to enhance the realistic sensation of the player, a more realistic video expression is desired.
In the real world, around the ballistic trajectory of a bullet fired from a gun or around a flame, the refractive index of air changes due to temperature change, and the phenomenon that the scenery on the other side looks distorted occurs, but such distortion of the space It is important how realistic it can be expressed on the screen.

  In computer graphics, as a method for expressing the refractive index of air, for example, there is a ray tracing method. The ray-tracing method is a method of determining an image that can be observed from the viewpoint by tracing the line of sight from the viewpoint in a virtual three-dimensional space, reflecting the light with an object that reflects light, and determining the refraction direction with an object that transmits light. is there. Rendering by ray tracing has the advantage that shadows, refractions, and reflections can all be accurately reproduced. However, the amount of computation is enormous, so a device that generates animation images in real time, such as a display device of a gaming machine, is processed. It was a method that was not suitable for the burden. For this reason, for example, in Patent Document 1, in a video game apparatus, a transparent object through which light is transmitted is displayed with a rich texture without using a method of accurately reproducing light refraction like the ray tracing method. A method is disclosed.

Japanese Patent Laid-Open No. 11-3432

  However, since the method disclosed in Patent Document 1 cannot accurately reproduce the refraction of light, it has not been possible to express a natural and highly realistic distortion of the space.

  Therefore, an object of the present invention is to express natural and highly realistic distortion of a space in an apparatus for generating an image in real time.

  An image generation apparatus according to the present invention is an image generation apparatus that generates an animation image in real time, and includes a texture data storage unit that stores a plurality of textures that express distortion of space, and a virtual three-dimensional space before the viewpoint. In the virtual three-dimensional space, a polygon placement unit for placing a plate polygon covering an area where the distortion of the space is to be produced, and a plurality of textures are sequentially pasted on the plate polygon for each frame to perform continuous rendering. A plurality of textures, a background image located behind an area where the space is desired to be distorted, as viewed from the viewpoint, is distorted reflecting light refraction. The textures that can be seen are arranged in order for each frame.

  According to the present invention, when generating an image in real time, the background image located behind the area where the distortion of the space is to be produced is accurately reflected on the plate polygon arranged in front of the viewpoint. Since the texture that is expressed as seen in the map is mapped, even if it is difficult to accurately reflect changes in refractive index, such as real-time image generation processing, natural and realistic distortion of the space can be obtained. Can be expressed.

In addition, the plurality of textures are arranged by arranging a transparent solid object in a region where the distortion of the space of the animation image is desired to be produced, deforming the solid object for each frame, and rendering the board among the rendered images. It is desirable that a texture obtained by processing only the area covered by the polygon is ordered for each frame.
Thereby, it is possible to create a texture that accurately reflects the change in refractive index.

Further, it is preferable that the rendering unit blurs a boundary line of the three-dimensional object using an alpha channel whose selection range is the display area of the three-dimensional object.
Thereby, a more natural image can be realized.

Further, when the region expressing the distortion of the space is a space around the trajectory of a bullet fired from a gun, for example, the transparent solid object may be a conical transparent object having the bullet as a vertex. it can.
Thereby, the distortion of the space around the trajectory when the bullet moves toward the target can be effectively produced.

Further, when generating an animation image in real time, a ring-shaped object that moves along the area of the conical transparent object may be displayed.
Thereby, the production effect can be further enhanced.

The image generation apparatus according to the present invention can be applied to a gaming machine.
Here, the gaming machine is not limited, but includes, for example, pachinko machines (including first-class pachinko machines and second-class pachinko machines), rotary gaming machines (hereinafter referred to as “slot machines”), and the like.

(Operation on the main control board)
FIG. 4 is a flowchart showing control by the main control board 10.
When a player inserts a medal and the start switch 46 is operated, the start means 173 detects that the start switch 46 is turned on, and the part lottery means 110 performs a lottery process for the part (step S101, Step S102). On the other hand, if the start switch 46 is not operated by the player and it is not possible to detect that the start switch 46 has been turned on, the start means 173 detects that the start switch 46 has been turned on until step S101 is detected. Repeat the process.

  In the combination lottery process in step S102, the combination lottery means 110 acquires a random number and performs a combination lottery process by comparing the acquired random number with the lottery table. The lottery result by the combination lottery means 110 is transmitted to the sub-control means 200 as winning combination information (step S103).

  The reel control unit 120 determines whether any one of the stop switch groups 47 has been operated (step S104). When any one of the stop switches is operated (step S104 / YES), reel control is performed so that the winning combination can be won, and the rotation of the reel corresponding to the operated stop switch is stopped (step S104). S105).

  If no winning combination has been won in the winning combination lottery process in step S102 (in the case of “losing”), the reel control unit 120 has not won any winning combination in step S105. The reel control corresponding to is performed.

  Subsequently, the reel control unit 120 determines whether all the stop switches are operated and all the reels are stopped (step S106). When all the reels have not stopped yet (step S106 / NO), the processing from the detection processing of presence / absence of the stop switch operation in step S104 is repeated.

  When all the reels are stopped (step S106 / YES), the stop symbol determination means 130 determines whether or not there is a winning based on the combination of symbols arranged on the activated effective line (step S107). As a result, if there is any winning (step S107 / YES), a winning process corresponding to the winning combination is executed (step S108).

Specifically, when the winning combination is a “special combination”, the game state control unit 160 performs a transition process for executing the “special game” from the next game until a predetermined end condition is satisfied.
On the other hand, if it is determined in step S107 that there is no winning (step S107 / NO), the process returns to step S101.

  Subsequently, during the “special game”, the game state control means 160 gives the reel control means 120 a “special game” so as to provide the player with a game state corresponding to the big bonus or regular bonus that is the “special role”. In addition to the internal reel control, the sub-control means 200 is caused to perform an effect for “special game”. When the specified number of games of the big bonus or the regular bonus is finished, a process of shifting to the “normal game” is performed.

  On the other hand, if the winning combination is not “special”, the special combination carry-over means 150 carries over the special combination until the combination of symbols corresponding to the selected special combination stops on one of the active lines 26a to 26c. To control.

  When the winning combination is “small role”, the gaming state control means 160 performs reel control so that symbols such as bells are aligned on the active line, and the sub-control means 200 uses “small role”. Production of a production or a small role announcement (display of a notification object, etc.) is performed. When the winning combination is “replay”, the bet (the number of bets) in the game is carried over to the next game, and when the winning combination is neither “special role” nor “replay”, the payout control means 140 Causes the hopper device 31 to pay out the number of medals corresponding to the winning combination.

FIG. 5 is a block diagram showing a functional configuration of the image sound generation means 220.
As shown in the figure, the image sound generation means 220 includes an object data storage unit 2201, a texture data storage unit 2202, an object arrangement unit 2203, a plate polygon arrangement unit 2204, a rendering unit 2205, an image data storage unit 2206, and a display control unit 2207. It has.

  Of the above configuration, the object data storage unit 2201 and the texture data storage unit 2202 correspond to the image ROM 72. The image data storage unit 2206 corresponds to the video RAM 73. The object placement unit 2203, the plate polygon placement unit 2204, the rendering unit 2205, and the display control unit 2207 are functionally realized by the image control IC 71.

(Object data storage unit 2201)
The object data storage unit 2201 stores object data that is original data of modeling conversion for generating a stereoscopic image such as a decorative design. The object data includes numerical information that defines the shape and arrangement of each object displayed in the virtual three-dimensional space. The contents of the object data are determined according to the modeling method. For example, when a surface model is used, one object data is a set of vertex coordinates of each polygon constituting the object when the reference coordinates preset for each object are used as the origin. Therefore, if each polygon is arranged at a relative position from the reference coordinates, the outer shape of the object is defined. The relative position (shape, orientation, size) of the polygon in the local coordinate system of each object is three-dimensionally defined by the object data.

(Texture data storage unit 2202)
The texture data storage unit 2202 stores a plurality of texture data.
Texture data is data that defines a texture that is mapped (expanded or pasted) to an object to be displayed. Texture is data relating to a pattern, transparency, and color mapped to the surface of an object or polygon that is a set of vertex coordinates. The texture data is image data created at a predetermined resolution for representing a pattern or the like, for example, bitmap data. In order to paste a texture onto a predetermined polygon, mapping processing is performed on the texture data by performing predetermined image conversion, for example, affine conversion, and expanding (expanding / reducing / deforming) the texture into a polygon shape. By changing the texture data used for each frame, a continuous animation image with a texture is formed.

  In addition to the premise that texture data is mapped to polygons, the texture data includes sprites, that is, bitmap data for images that are directly arranged in a developed two-dimensional image as a single picture. . Such a sprite is suitable for displaying an image that does not require a three-dimensional effect. However, since it can be used as a part of the object, a part of the object described above may be configured by the sprite.

  In the present embodiment, the texture data storage unit 2202 stores a plurality of textures expressing the distortion of the space. This texture is created using a three-dimensional computer graphics creation device as will be described later.

(Object placement unit 2203)
The object placement unit 2203 places one or more objects in the virtual three-dimensional space.
The object placement unit 2203 reads out object data of an object to be placed in the virtual three-dimensional space from the object data storage unit 2201. Then, modeling conversion calculation processing is executed on the object data defined in the local coordinate system to determine the arrangement of the objects in the virtual three-dimensional space defined in the world coordinate system. By this coordinate transformation, arbitrary three-dimensional geometric transformation (translation, rotation, scale transformation, shear, reflection) is performed, and the position, orientation, size, etc. of the object in the virtual three-dimensional space are determined. For example, a vertex coordinate (x, y, z) in a local coordinate system of a polygon is changed to a vertex coordinate (X, Y, Z) in the world coordinate system by modeling conversion calculation, and the vertex position in the virtual three-dimensional space is defined Is done.

(Plate polygon placement unit 2204)
The plate polygon arrangement unit 2204 arranges a plate polygon (polygon without thickness) that covers an area in which a distortion of the space is to be produced in the virtual three-dimensional space before the viewpoint of the virtual three-dimensional space. By mapping a plurality of textures expressing the above-mentioned space distortion on the plate polygon, the space distortion can be expressed.

(Rendering unit 2205)
The rendering unit 2205 performs rendering based on the arrangement of objects, the viewpoint position in the virtual three-dimensional space, light source (light) setting information, and the like.
The rendering unit 2205 first converts the arrangement of each object defined in the world coordinate system into a viewpoint coordinate system based on the viewpoint set in the virtual three-dimensional space. By this conversion, each object is defined in a coordinate system in which the viewpoint position is the origin (0, 0, 0) and the depth direction is the Z-axis direction. Further, the rendering unit 2205 performs a perspective projection calculation process on each object, and calculates coordinates on the projection plane corresponding to the display area. In the perspective projection calculation processing, an object farther away is developed on a projection plane in inverse proportion to the set distance from the viewpoint of the three-dimensional space. At this time, if objects appear to overlap each other from the viewpoint, hidden line removal and hidden surface removal are performed. The rendering unit 2205 maps the texture to the polygon of the object when texture data exists. Further, the rendering unit 2205 performs polygon shading based on the light setting information set in the virtual three-dimensional space and the color information provided at each vertex.

  In particular, in the present embodiment, the rendering unit 2205 generates a frame image by mapping a texture expressing a distortion of the space to the plate polygon arranged by the plate polygon arrangement unit 2204.

(Image data storage unit 2206)
The image data storage unit 2206 stores the rendered image data. The stored image data is output to the liquid crystal display device 80, whereby a three-dimensional graphics image is displayed.

(Display control unit 2207)
The display control unit 2207 transfers the frame image data to the liquid crystal display device 80 at each drawing timing. Based on the transferred frame image data, the liquid crystal display device 80 displays an image corresponding to the frame image data in the display area.

  Next, image generation processing executed in the image sound generation unit 220 will be described using the flowchart of FIG.

First, the image sound generation means 220 determines whether or not it is the drawing timing (step S201). Here, the drawing timing is a predetermined timing in time for the next frame image data update process, and is appropriately determined by the system. The drawing timing may be set every frame period, or may be set every one or more frame periods. If it is not yet the drawing timing (NO), the process proceeds to step S207, and the display control unit 2207 continues the display control based on the frame image data at the previous drawing timing.

  If the drawing timing is determined in step S201 (YES), the process proceeds to step S202, where the object placement unit 2203 reads the object data from the object data storage unit 2201, and executes the modeling conversion operation on the vertex coordinates of each polygon. The polygon coordinates in the world coordinate system are determined.

  Next, in step S203, the image sound generation means 220 determines whether or not a spatial distortion effect process is necessary. If it is determined that the spatial distortion effect is not necessary, the process proceeds to step S205, and the rendering unit 2205 performs a rendering process for a normal object.

  On the other hand, if it is determined in step S203 that a space distortion effect is necessary, the process proceeds to step S204. In step S204, the plate polygon arrangement unit 2204 arranges a plate polygon that covers a region in the virtual three-dimensional space where the distortion of the space is desired before the viewpoint of the virtual three-dimensional space.

  FIG. 7 is a diagram illustrating a positional relationship among a virtual camera, a plate polygon, an object, and the like in a virtual three-dimensional space. In the figure, C represents a virtual camera, Ch represents a character object, B represents a background object, and P represents a plate polygon. FIG. 8 is a diagram showing a two-dimensional image with a plate polygon placed in front of the virtual camera. The plate polygon P is arranged so as to cover the entire area where the distortion of the space is desired.

  Next, in step S205, the rendering unit 2205 executes a rendering process. First, the rendering unit 2205 performs viewing conversion. A normalization transformation is then performed, followed by a perspective projection transformation. Then, necessary hidden line removal processing and hidden surface removal processing are executed.

Next, when there is texture data, the rendering unit 2205 reads the texture data from the texture data storage unit 2202 in units of polygons. Then, frame image data is generated by performing texture mapping processing, shading processing, etc. on each polygon.
In the present embodiment, the rendering unit 2205 generates a frame image by mapping the texture expressing the distortion of the space to the plate polygon arranged by the plate polygon arrangement unit 2204 in step S204.

Next, in step S <b> 206, the rendering unit 2205 outputs the generated frame image data to the image data storage unit 2206.
Finally, in step S207, the display control unit 2207 outputs the frame image data stored in the image data storage unit 2206 to the liquid crystal display device 80.

  Next, a description will be given of a method for creating a plurality of textures that are mapped to plate polygons by the rendering unit 2205 and express distortion of space. The texture is created using a 3D computer graphics creation device. The three-dimensional computer graphics creation device is not a device that generates and displays an image in real time like the image sound generation means 220 but a device that renders a series of frame images in advance and creates a reproducible animation image. is there.

FIG. 9 is a flowchart illustrating an example of a texture creation processing procedure according to the present embodiment.
First, in step S301, a transparent object having a three-dimensional shape corresponding to the shape of the area is arranged in an area where the distortion of the space of the image generated by the image sound generation means 220 is to be expressed.

In step S302, the transparent object is deformed for each frame.
Next, in step S303, each frame image is rendered based on the transparent object arrangement and deformation information in steps S301 and S302. In the three-dimensional computer graphics creation device, the refractive index of light that passes through a transparent object at the time of rendering is calculated by, for example, a ray tracing method, and reflected in the frame image. Therefore, by deforming the transparent object for each frame, the background seen through the transparent object appears to be distorted due to the change in the refractive index.

  Next, in step S304, only the region corresponding to the plate polygon arranged by the plate polygon arrangement unit 2204 in each rendered image is processed into a texture. This area includes a transparent object display area. The completed texture is stored in the texture data storage unit 2202 as a continuous texture.

  The image generation process shown in FIG. 6 is performed using the texture created as described above. Since the image created by the procedure shown in FIG. 9 reflects the change in the refractive index due to the deformation of the transparent object, when the image is reproduced by the image sound generation means 220, it is simply mapped as the texture. The same effect as changing the refractive index by changing the transparent object arranged in the virtual three-dimensional space can be obtained. For this reason, it is not necessary to arrange the transparent object in the virtual three-dimensional space when the image sound generation unit 220 generates the real-time image. Further, in the real-time image generation by the image sound generation means 220, even if a transparent object is arranged in a virtual three-dimensional space and deformed for each frame, the calculation processing is not in time for the performance of the hardware, and the change in the refractive index is caused. It is difficult to realize processing that accurately reflects.

  10 to 12 are diagrams showing two-dimensional images rendered by pasting the texture representing the distortion of the space created by the procedure shown in FIG. 9 on the plate polygon shown in FIG. Here, in order to express the distortion of the space around the trajectory of the bullet fired from the gun, by transforming the conical transparent object G whose vertex is the bullet fired toward the character object Ch, Expresses distortion. Thus, the shape of the transparent object is determined according to the shape of the space to be distorted. As shown in FIGS. 10 to 12, the background seen through the transparent object G appears distorted. Further, as the bullet fired from the gun approaches the target character object Ch, the shape of the transparent object G also changes. As a result, the area where the space is distorted changes according to the movement of the bullet, resulting in a natural and highly realistic image.

  For each texture image created by the procedure shown in FIG. 9, an alpha channel is created with the display area of the transparent object as a selection range, and the texture is mapped to the board polygon placed by the board polygon placement unit 2204. At this time, the created alpha channel may be used as a mask. By blurring the alpha channel, the border line of the transparent object portion can be blurred when an image is generated, and a more natural image can be realized.

  Further, in order to further enhance the effect in the images shown in FIGS. 10 to 12, as shown in FIGS. 13A and 13B, when the image is generated by the image sound generation means 220, a gradually expanding halo continues from the bullet. As an effect to be generated, the ring-shaped object R may be displayed so as to overlap the conical transparent object G. With time, as the bullet approaches the character object Ch, the ring object R changes from the state shown in FIG. 13A to the state shown in FIG. 13B. By displaying the ring object R, not only the change of the refractive index but also the air flow around the trajectory is expressed, and the image expression is more realistic.

  As described above, according to the present embodiment, an image acoustic generation is performed by creating an image that accurately reflects a change in refractive index using a three-dimensional computer graphics creation device, and processing the created image as a texture. When the real-time image is generated by the means 220, the processed texture is attached to the plate polygon arranged in front of the camera, so that the change in the refractive index is accurately reflected as in the real-time image generation processing in the current game machine. Even when it is difficult to realize processing, it is possible to express the distortion of a natural space with a high sense of reality.

(Pachinko machine)
In the first embodiment, the slot machine has been described as an example. However, the image generation apparatus according to the present invention can also be applied to other gaming machines such as a pachinko machine.

FIG. 14 is a front view showing an example of the external configuration of the pachinko machine.
In FIG. 14, the pachinko machine is configured to include a game board (gauge board) that constitutes a game board surface and a game machine frame that supports and fixes the game board. The game board includes a plurality of nails 101, windmills 102a and 102b, a normal symbol operating gate 103, a normal electric accessory 104, a center decorative part 105, a special symbol display device 106, an effect display device 107, a normal symbol display device 108, an outside A rail 110, an inner rail 109, and the like are provided as game parts. Further, the game board is provided with a general winning port 111, a starting winning port 112, a big winning port 113, and an out port 114.

A liquid crystal display device for performing the above is provided. The effect display device 107 is not limited to a liquid crystal display device, and may be configured by a display device such as a plasma display. The image generation device according to the present invention is incorporated in the effect display device 107, and the image generated by the image generation device is displayed on the display screen 118 of the effect display device 107.

(Modification)
In the first embodiment, the arrangement position of the plate polygons arranged by the plate polygon arrangement unit 2204 is constant. However, the position of the plate polygons may be changed in accordance with the change of the area where the distortion of the space is desired. Good. For example, when the range in which the distortion of the space is desired to move greatly moves on the screen, it is not possible to cope with the deformation of the transparent object alone, and it is necessary to move the entire transparent object in the virtual three-dimensional space. In this case, the display area of the transparent object may be out of the range covered by the plate polygon. Therefore, the plate polygon placement unit 2204 changes the position of the plate polygon according to the movement of the region where the distortion of the space is to be expressed, so that it can cope with any change in the region where the distortion of the space is to be expressed. Can do.
