The present invention relates to a device and a display program.

  A moving image (CG moving image) produced by computer graphics is used not only for a television, a movie, and a game, but also as a video content displayed on a liquid crystal display such as a slot machine or a pachinko machine.

  For example, a slot machine generally includes a liquid crystal display capable of displaying a CG video in addition to a reel device for displaying whether a winning combination has been established or not, and a reel device based on the result of a lottery performed internally. On the other hand, on the liquid crystal display, various CG moving images produced with the intention of various effects are displayed for each gaming state.

  FIG. 10 shows one scene of a CG moving image displayed on the liquid crystal display of such a slot machine.

  As shown in the figure, in this scene, a person image 2 and an aura image 3 rising from the person 2 are displayed in the display screen 1 of the liquid crystal display.

  The aura image 3 is an effect image for encouraging the player's expectation for the establishment of a winning combination. Different types of winning combinations are elected depending on the display color of the aura image 3, or the probability is high. Is notified to the player. In addition, when a special winning combination (for example, “BB” role or “RB” role) that is expected to pay out many medals is won, or when the probability is high, the player has a higher expectation. In a situation where it is desirable to give, a special aura image 3 is displayed that changes the display color to the extreme color.

  The aura image 3 in FIG. 10 depicts a special aura image in which the display color changes to a chromatic color, and the thin line 3a in the aura image 3 is different from each other in a plurality of small areas partitioned by the thin line 3a. It is shown that the color is colored, and the number and shape of the small areas change with time, and the color in each small area also changes with time.

  Conventionally, when displaying a color that changes to a chromatic color in a predetermined area on the display screen such as the aura image 3, pixels in individual small areas constituting the area or the small areas are arranged. A method has been employed in which the R value, G value, and B value of the texture are independently changed according to sine functions having different periods.

However, in such a method, a moment when all of the R value, G value, and B value become 1 or 0 occurs, and at that moment, the small area is displayed in white or black. There is a problem that it gives a sense of incongruity, and the aesthetics as intended by the producer cannot be obtained.

A signal is transmitted to the effect processing unit 50, and a predetermined signal is transmitted to the special game processing execution unit 46 in order to execute a special game in which a large number of medals are paid out in a predetermined number of games thereafter.

  In FIG. 3, 50 indicates an effect processing unit that is a functional block mainly realized by the effect control board 30.

  As shown in the figure, the effect processing unit 50 is a liquid crystal display including an object recording unit 51, a texture recording unit 52, an object motion recording unit 53, a virtual camera motion recording unit 54, an image generation unit 55, and an aura image control unit 56. A control unit 50a is provided.

  The object recording unit 51 has a large number of polygons representing a three-dimensional shape such as a person, animals, buildings, roads, forests, forests, mountains, rivers, etc. used in the CG video displayed on the liquid crystal display 16. The object recording unit 51 records data of an object. The object recording unit 51 also includes data of an aura object that is used to generate a normal aura image or a special aura image, for example, a single polygon having a rectangular shape. It is recorded. In order to distinguish from the aura object, an object other than the aura object is hereinafter referred to as a “general object”.

  The texture recording unit 52 records data such as a planar shape, a pattern, a color, and transparency of a texture used for texture processing of each object recorded in the object recording unit 51. It is recorded in association with each object in the object recording unit 51. The texture recording unit 52 also records aura texture data having a circular shape, for example, prepared corresponding to the aura object. Note that color and transparency data are not specified for this aura texture, and an aura image control unit 56 (to be described later) determines the color and transparency according to the type of effect designation signal.

  In the object motion recording unit 53, the time series data (the frame counter value) of the position coordinates of each general object (representative point) in the three-dimensional virtual space prepared for each of the various scenarios including the plurality of effect patterns. Data defined in association with each other). In addition to the above, the object motion recording unit 53 stores data defining the direction of each general object in the virtual three-dimensional space and the relative position and angle of each polygon constituting the general object with respect to the representative point in time series. Can also be recorded.

  The virtual camera operation recording unit 54 records time-series data such as the position coordinates, direction, and angle of view of the virtual camera in the three-dimensional virtual space.

  In accordance with data recorded in the object recording unit 51, the texture recording unit 52, and the object coordinate recording unit 54, the image generation unit 55 puts one or a plurality of general objects to which corresponding textures are pasted in a virtual three-dimensional space. In addition to mapping, a process of drawing a video that falls within the angle of view of the virtual camera moving in the virtual three-dimensional space according to the data of the virtual camera operation recording unit 54 in the frame buffer 30d for each frame is executed.

  The video written in the frame buffer 30d is transmitted to the liquid crystal display 16 for each frame and displayed.

  The aura image control unit 56 includes an aura object generating unit 56a, a position specifying unit 56b, a size specifying unit 56c, a transparency specifying unit 56d, an HSB specifying unit 56e, and an RGB determining unit 56f, and a normal aura effect or a special aura effect. When the effect processing unit 50 receives an effect specifying signal for specifying the position, the position coordinates and sizes of a plurality of aura objects in the virtual three-dimensional space, and the transparency and RGB values of the texture used for each aura object are specified. The signal to be transmitted is transmitted to the image generation unit 55.

That is, the aura object generation unit 56a executes processing for generating an aura object at a constant frequency (for example, one rate per frame time), and the generated aura object is first mapped in the virtual three-dimensional space. Then, when a predetermined frame time t ₂ (for example, 90 frames) has elapsed, a process for eliminating the aura object is executed.

  The position specifying unit 56b executes a process of specifying the position of each aura object generated by the aura object generating unit 56a in the three-dimensional virtual space.

  4A to 4C show exemplary positional relationships of the virtual camera 61, the person object 62, and the aura object 63 arranged in the three-dimensional virtual space in a normal aura effect or a special aura effect in time series. FIGS. 5A to 5C show images within the angle of view 65 of the virtual camera 61 in the states of FIGS. 4A to 4C, respectively. Note that arrows X to Z in the figure indicate the X-axis direction (height direction), Y-axis direction (horizontal direction), and Z in the viewpoint coordinate system, which are orthogonal coordinates set with reference to the virtual camera 61 in the virtual three-dimensional space. An axial direction (depth direction) is shown.

The position specifying unit 56b determines the position coordinates (X coordinate value x, Y coordinate value y, and Z coordinate value z) of the aura object 63 in the viewpoint coordinate system as shown in the following equations (1) to (3).

Here, _{x 0} and _{z 0} is a fixed coordinate value, _{y 0} is the position specifying unit 56b in a range from _{y a} to _{y b} on Y coordinates shown in FIG. 5 (a) is selected at random coordinates Value. Further, t is a frame time from when the aura object 63 is generated, that is, T ₁ is a frame counter value incremented by 1 every frame time, and T ₀ is a frame counter value at the time when the aura object 63 is generated. a _T 1 -T ₀ at the time of the T _1. Further, z _p is a positive constant, and z ₀ + z _p × t ₂ (t ₂ is a required frame time from generation of the aura object to disappearance) is somewhat higher than the head of the general object 62 of the person. A value that is about the height is set.

Therefore, Aura objects 63, intermediate specific height of the virtual camera 61 and the person object 62 any position from _{y a} in (see FIG. 4 (a)) to _{y b} (see FIG. 5 (a)) Then, without changing the X coordinate value x and the Y coordinate value y, the virtual three-dimensional space rises as the frame time elapses and disappears at a certain height.

Further, the size designating unit 56c determines the size of the aura object (the width dimension W and the height dimension H in the virtual three-dimensional space) as in the following formulas (4) and (5).

Here, similarly to the above, t and t ₂ are the frame time from the generation of the aura object 63 and the required frame time from the generation of the aura object 63 to the deletion, and t ₁ is 0 or more, t Fixed values determined within a range of less than ₂ , W ₀ and H ₀ are initial values of the width and height dimensions of the aura object, and s _{1 to} s ₄ are positive constants.

  Therefore, the size of the aura object 63 is initially increased as it rises in the virtual three-dimensional space (FIG. 4 (a), FIG. 5 (a) → FIG. 4 (b), FIG. 5 (b)). After reaching a certain intermediate height, the size is reduced (FIG. 4 (b), FIG. 5 (b) → FIG. 4 (c), FIG. 5 (c)).

  As shown in FIGS. 4 and 5, the aura object 63 is a two-dimensional object composed of a single polygon, has only dimensions (W and H) in the X-axis and Y-axis directions, and is in the Z-axis direction. Does not have dimensions.

  Further, 64 shown in FIGS. 5A to 5C is an aura texture pasted on the aura object 63, and the aura texture 64 is positioned on the outer side of the colored portion 64a having a circular shape as shown in the figure. The transparent part 64b is configured.

  The transparency designating part 56d determines the transparency α in the colored part 64a of the aura texture 64 according to the following equation (6).

α = α ₀ + α ₁ × t (6)
Here, t is the frame time after the generation of the aura object 63 as described above, α ₀ is the initial value of transparency, and a value between 0 and 1 is set. α ₁ is a positive constant smaller than (1−α ₀ ) / t ₂ (t ₂ is the required frame time).

  Further, the transparency specifying part 56d always gives 1 as the transparency of the transparent part 64b.

  The HSB designating unit 56e determines the hue value H of the coloring unit 64a according to the following formula (7) when the production processing unit 50 receives the production designating signal specifying the special aura production.

H = MOD ₃₆₀ (c ₁ × T ₀ + c ₂ × t) (7)
Here, t is the frame time after the aura object 63 is generated, and T ₀ is the frame counter value T ₁ at the time when the aura object 63 is generated, as described above. Further, c ₁ and c ₂ are positive or negative constants, and MOD ₃₆₀ () indicates a remainder when a value in parentheses is divided by 360.

  Here, the hue value H derived as described above corresponds to an angle on the hue circle that connects hues in the order of red, yellow, green, blue, and purple. For example, H is 0 when red and 90 is yellow. , 150 corresponds to green, 240 corresponds to blue, and 300 corresponds to purple.

Therefore, the hue of the colored portion 64a at the time of generation of the aura object 63 varies as fast determined by the constant c _1, aura object 63 located above the (aura object 63 elapsed time from the generation is large) the degree of difference in color of the colored portion 64a of the aura object 63 (aura object 63 elapsed time from the generation of small) located below will be determined by the constant c _2.

  The HSB designation unit 56e always gives 1 as the saturation value S and the brightness value B of the coloring unit 64a.

  When the effect processing unit 50 receives an effect designation signal specifying the normal aura effect, the RGB determination unit 56f determines the RGB value of the coloring unit 64a based on the color designation signal received together with the effect designation signal.

  That is, when the received color designation signal is a signal for specifying yellow, “R = 1, G = 1, B = 0” are determined as RGB values, respectively, and this is a signal for specifying green. Determines “R = 0, G = 1, B = 0”, and determines “R = 1, G = 0, B = 0” if the signal specifies red.

  In addition, when the effect processing unit 50 receives the effect designation signal for specifying the special aura effect, the RGB determining unit 56f converts the HSB value designated by the HSB designation unit 56e according to the algorithm shown in FIG. The RGB value of 64a is derived.

  Note that “sat” and “bri” in the algorithm of FIG. 6 are the saturation value S and the lightness value B specified by the HSB specification unit 56e, respectively, and “hue” is the hue value H specified by the HSB specification unit 56e. Is divided by 360.

  When the effect processing unit 50 receives an effect designation signal specifying a normal aura effect or a special aura effect, the image generation unit 55, together with the general object and the virtual camera, determines the position coordinates x, y, z, and size determined as described above. The aura object 63 generated by the aura object generation unit 56a is mapped in the virtual three-dimensional space for each frame time according to the W, H, transparency α, and RGB values, and the video included in the angle of view of the virtual camera is displayed in the frame buffer 30d. Draw on.

  Here, when drawing each aura object 63, the image generating unit 55 is based on the RGB value of the coloring unit 64a and the distant view based on the transparency α of the coloring unit 64a specified by the transparency specifying unit 56d. A process of synthesizing the RGB value of the texture given to the object is executed.

That is, assuming that the RGB value determined as described above for the coloring unit 64a is g ₁ and the RGB value of a general object located in the distant view when viewed from the virtual camera 61 is g ₂ , the frame buffer 30d corresponding to the coloring unit 64a The pixel value (RGB value) g of this pixel is determined by the following equation (8).

g = g ₁ × (1−α) + g ₂ × α (8)
In addition, when a plurality of aura objects 63 are located close to each other and overlap occurs in the colored portions 64a of the plurality of aura objects 63, the following formula is used for calculating the above equation (7) for the overlapped portions. The RGB value g ₁ and transparency α obtained from (9) and (10) are used.

In the above formulas (8) and (9), n is the number of the colored portions 64a that are overlapped, and g _1i and α _i are the pixel value g ₁ and the transparency α of each colored portion 64a.

  In the special aura effect, since the position and size of each aura object 63 in the three-dimensional space and the color and transparency of the coloring portion 64a are determined in the manner described above, a large number of aura objects 63 generated every frame time are determined. However, while changing the color within the angle of view of the virtual camera 61 and intricately overlapping, the virtual camera 61 moves in the height direction of the virtual three-dimensional space. An aura image 3 having the form shown in FIG. 10 is formed, and a plurality of small regions constituting the aura image 3 change colors and shapes with time while maintaining a vivid pure color.

  The lighting control unit 50b and the sound control unit 50c included in the effect processing unit 50 blink the lighting devices 17a to 17c in a predetermined manner according to the effect designation signal transmitted from the effect determining unit 43, and sound effects from the speakers 18a and 18b. Is output.

  Hereinafter, processing executed by the liquid crystal display control unit 50a will be described with reference to the flowcharts shown in FIGS.

  As shown in FIG. 7, after the frame counter T is reset (step 1) and incremented (step 2), the image generation unit 55 associates the general object associated with the frame counter T with the general object. The obtained texture data is acquired from the object recording unit 51, the texture recording unit 52, and the object motion recording unit 53, and a process of mapping each general object subjected to texture processing in the virtual three-dimensional space is executed (step 3).

  The image generation unit 55 further acquires data related to the virtual camera 61 associated with the frame counter T from the virtual camera operation recording unit 54 and places the virtual camera 61 in the virtual three-dimensional space (step 4). A video image having an angle of view of 61 is drawn in the frame buffer 30d (step 5).

A process of generating a CG moving image based on the data is executed.

That is, in step 22, general object and texture data associated with the frame time T ₁ in the special aura effect are acquired from the object recording unit 51, texture recording unit 52, and object motion recording unit 53, and stored in the virtual three-dimensional space. A process of mapping the textured one or more general objects is executed.

In step 23, according to the specified or derived data in step 17-20, the process of mapping the aura object O _n in the virtual three-dimensional space is performed. That is, an aura texture composed of a colored portion 64a colored with an RGB value g ₁ (O _n ) of transparency α (O _n ) and a transparent portion 64b of transparency 1 is pasted, and the width dimension W (O _n ) and height are pasted. each aura object _{O n} having a size dimension H _{(O n),} the coordinate values in each virtual three-dimensional space _x (O _n), the process of placing the y (O n), z ( O n) is performed .

In step 24, the virtual camera 61 based on data associated with the frame time T ₁ in the special aura effect virtual camera operation recording unit 54 is placed in the virtual three-dimensional space, in step 25, the field of the virtual camera 61 The video that enters the corner is drawn in the frame buffer 30d.

In step 26, the process of erasing the first aura object O _n more than a predetermined frame time from when placed in the virtual three-dimensional space (e.g., 90 frames) has elapsed is performed. That is, for all the aura object O _n being generated at that time, T 1 _-T 0 _{(O n)} is checked whether it exceeds a predetermined value (e.g., 90), when it exceeds its data about the aura object O _n is erased.

After that, for example, it is determined whether or not a special aura effect ending condition such as stopping of all reel devices 12L, 12C, and 12R is satisfied (step 27). returns to step 2, when not satisfied, the process for executing the rendering of the image in the next frame time T ₁ is returned to step 14.

  In the ordinary aura process shown in FIG. 9, the process corresponding to step 20 in the special aura process (HSB value designation by the HSB designation unit 56e) is not executed, and the effect processing unit 50 performs the effect in step 41 corresponding to step 21. A process similar to the special aura process is executed except that the process of determining the RGB values is executed in a predetermined manner according to the color designation signal received from the determination unit 43.
