Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an image display method for displaying an image of a game or the like, and more particularly to an image display method that provides a fresh effect using polygons and an image display method that is suitable for a game using a touch panel by a plurality of players.
[0002]
[Prior art]
In a game device, it is necessary to dynamically display a large number of graphic data such as characters on a display screen on a background screen. Each graphic data is expressed as a polyhedron. Each polygonal plane constituting the graphic data is called a polygon, and is constituted by coordinate values and color data of each vertex of the polygonal plane.
[0003]
In recent years, with the sophistication and complexity of games, expression of various effects is required. In the case of image display using polygons, the surfaces of the polygons are expressed in a uniform color, so the objects composed of the polygons tend to be a game-specific and superb image. In particular, it has been difficult to realistically express a state in which an object is exposed to light or a fluid such as a liquid.
[0004]
On the other hand, there is a game apparatus in which a touch panel is provided on a display screen and a player gives a predetermined instruction by touching the touch panel. Since such a game device is an operation using a touch panel, even an unfamiliar player can enjoy a game by operating without resistance.
[0005]
A game by a game apparatus having a touch panel can detect only one point on the touch panel. Even in a game in which two or more players can participate, there is only one player that can be operated during the game, and basically a single game is alternately performed.
[0006]
[Problems to be solved by the invention]
As described above, in the case of image display using polygons, for example, there is a demand for an image display method that can realistically represent a state in which an object is exposed to light or a fluid such as a liquid.
[0007]
Further, in the case of a game device using a touch panel, there is no game in which two or more players can participate together, so an image display method suitable for such a game is required.
[0008]
An object of the present invention is to provide an image display method capable of expressing a state where light strikes an object or a fluid such as a liquid with a sense of reality using polygons.
[0009]
Another object of the present invention is to provide an image display method suitable for a game in which a plurality of players can participate together using a touch panel.
[0010]
[Means for Solving the Problems]
The object is to specify a polygon having coordinate values of a plurality of vertices and color data of the plurality of vertices, and a surface whose surface is identified from the coordinate values of the plurality of vertices from the color data of the plurality of vertices. An image display method for displaying an image is achieved by dynamically changing color data of a plurality of vertices of the polygon and dynamically changing the color of the surface. The
[0011]
In the image display method described above, the color data of the plurality of vertices of the polygon is dynamically changed within a predetermined change amount with reference to the predetermined color data, and the color of the surface is dynamically changed. Also good.
[0012]
In the image display method described above, the color data of the plurality of vertices of the polygon is changed at a predetermined period within a predetermined change amount with reference to the predetermined color data, and the phase of the predetermined period at which the color data changes May be shifted from each other with respect to the plurality of vertices.
[0013]
The above object is a game image display method in which a predetermined instruction is given by a plurality of players sequentially contacting a touch panel provided on a display screen, and this is displayed to the players in the order of contact. This is achieved by an image display method characterized by displaying that fact to the waiting player and displaying a common accessible area where the plurality of players come into contact.
[0014]
The above object is an image display method for a game in which a plurality of players sequentially contact a touch panel provided on a display screen to give a predetermined instruction, wherein the individual contact areas are in contact with the plurality of players. By displaying an image, displaying that it is possible to contact the contact area of the player in the order of contact, and displaying that the contact area of the player waiting for the order cannot be contacted Achieved.

DETAILED DESCRIPTION OF THE INVENTION
A game device according to an embodiment of the present invention will be described with reference to the drawings.
[0016]
(Configuration of game device)
The configuration of the game device according to the present embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is an external view of the game apparatus according to the present embodiment, and FIG. 2 is a block diagram of the game apparatus according to the present embodiment.
[0017]
As shown in FIG. 1, the game apparatus 10 includes a base unit 12 placed on a floor surface of a game center or the like. A game board 14 for controlling the operation of the game apparatus 10 is housed inside the base unit 12, and two columns 16 are attached obliquely rearward to the floor surface on both front sides thereof. The base unit 12 and the column 16 are integrated so that the front surface of the base unit 12 does not protrude forward from the column 16.
[0018]
A game operation unit 18 is held above the base unit 12 by opposing columns 16. Since the game device of this embodiment is operated by a touch panel, no operation buttons or the like are provided on the upper surface of the game operation unit 18, and a description of the game and a coin insertion slot 20 are provided. A coin chute 22 for determining coins inserted by the player is integrated on the lower surface side of the game operation unit 18. Coins discriminated by the coin chute 22 are guided to the lower base unit 12 through the coin path of the column 16.
[0019]
A cable for connecting the base unit 12, the game operation unit 18, and the monitor unit 24 passes through the column 16. By passing the cable through the column 16, a design with a clean impression can be obtained without exposing the disturbing cable to the outside.
[0020]
A monitor unit 24 is provided in the vicinity of the game operation unit 18 and above it. The monitor unit 24 is fixed to the column 16 by a fixing means such as a bolt. The monitor unit 24 outputs a game screen to the player based on the video signal output from the game board 14.
[0021]
The monitor unit 24 is provided with a monitor 26 for displaying a game screen, and a touch panel 28 is provided on the surface of the monitor 26. A player can give a predetermined instruction to the game by touching the touch panel 28 while viewing the game image displayed on the monitor 26.
[0022]
Above the monitor unit 24, a bridge member 30 for connecting the two opposing columns 16 in the lateral direction is provided. The bridge member 30 is also fixed to the upper end of the column 16 with a bolt (not shown) or the like, as in the other units.
[0023]
As a result, the game operation unit 18 and the monitor unit 24 serving as an interface with the player are positioned in a frame formed by the left and right columns 16, the base unit 12, and the bridge member 30, and are in a stable state between the columns 16. Supported by
[0024]
Inside the bridge member 30, a fluorescent lamp 32 for emitting the member itself is housed, and a decoration unit 34 on which a device name, a game name, a logo, and an illustration are drawn is further mounted. .
[0025]
As shown in FIG. 2, the game apparatus 10 is connected to a CPU 42 that performs arithmetic processing and a system memory (RAM) 44 that is used as a buffer memory via a bus. A system memory (RAM) 44 temporarily reads the program and model conversion data of the game recording medium 40 and is used as a buffer memory for arithmetic processing. Further, a rendering processor 48 that performs rendering according to a drawing command generated by a drawing library and a frame memory 50 in which an image signal drawn by the rendering processor 48 is recorded are connected via a bus arbiter 46. Further, an audio processor 52 that generates audio data and an audio memory 54 that records the generated audio data are connected via a bus arbiter 46. The image data recorded in the frame memory 50 and the audio data recorded in the audio memory 54 are displayed and output on the display device 26 such as a video monitor.
[0026]

The bus arbiter 46 is also connected to a boot ROM 58, and a boot operation when the power is turned on is performed by executing data in the boot ROM 58. Further, the game apparatus 10 connects the game recording medium 40 via the bus arbiter 46.
[0027]
(Polygon image display method)
Polygon image display in the game device of this embodiment will be described with reference to FIGS. A stained glass image shown in FIG. 3 will be described as an example.
[0028]
In the game apparatus, in order to display graphics such as characters and objects on the display screen, each graphic is represented as a polyhedron and each polygonal plane is displayed using a polygon. The polygon is composed of coordinate values and color data of each vertex of the polygon plane.
[0029]
For example, in the case of the stained glass image shown in FIG. 3, the square stained glass image 60 is configured by combining an image 62 of an irregular glass piece. Further, the irregular glass piece image 62 is formed by combining a large number of triangular polygons 64.
[0030]
The triangular polygon is configured as a triangular plane connecting three vertices A, B, and C, as shown in FIG. As shown in FIG. 4B, the polygon data includes a polygon number, vertex A coordinate data Xa, Ya, Za and color data Ca, vertex B coordinate data Xb, Yb, Zb and color data Cb. , Vertex C coordinate data Xc, Yc, Zc and color data Cc. The color data Ca, Cb, and Cc are red (Red), green (Green), and blue (Blue) data Ca (Ra, Ga, Ba), Cb (Rb, Gb, Bb), and Cc (Rc). , Gc, Bc). The color of each vertex is determined by the data values of the three primary colors (R, G, B). The data of the three primary colors (R, G, B) are values in the range of 0 to 255, as shown in FIG.
[0031]
The color in the triangular plane of the polygon is determined by the color data of the vertices A, B, and C. For example, if the color data of vertices A, B, and C are all the same, for example, red, the polygon surface is painted red. If the color data of vertices A, B, and C are different from each other, as shown in FIG. 3, the in-plane of the polygon is linearly complemented according to the distance from the vertex, and smooth gradation is applied as shown in the lower part of FIG. Become a color. The effect of stained glass is expressed by the combination of smoothly graduated triangular polygons.
[0032]
In this embodiment, the color data of each vertex of the polygon is dynamically changed to dynamically change the color of the polygon surface. Specifically, polygon data read from the storage medium 40 or the like is expanded in the system memory 44, and the color data of each vertex of the polygon stored in the system memory 44 is rewritten.
[0033]
For example, the color data of the vertex A of the polygon shown in FIG. 4 changes from blue to red to white along the time axis, and the color data of the vertex B changes from red to yellow to black along the time axis. Then, the color of the center point between vertex A and vertex B changes from purple to orange to gray.
[0034]
Various methods are possible for changing the color data of each vertex. For example, two of the three vertices may be fixed and only one vertex may be changed. An effect of changing the color near one vertex of the triangular polygon can be obtained. Further, only one of the three vertices may be fixed and only two vertices may be changed. An effect of changing the color near one side of the triangular polygon can be obtained. Further, all three vertices may be changed. An effect of changing the overall color of the triangular polygon can be obtained. Further, when the change amount of the color data is small, the color tone of the set color changes, but when the change amount of the color data is large, the color itself changes.
[0035]
In addition, as a method of changing the color of each vertex, an effect of mainly changing light and dark is obtained when red (R), green (G), and blue (B) are all changed in the same increasing direction or decreasing direction. Further, when two of red (R), green (G), and blue (B) are changed in the same increasing direction or decreasing direction, an effect of mainly changing the color is obtained. Further, when two of red (R), green (G), and blue (B) are changed in the increasing direction and the other in the decreasing direction, an effect of changing the hue is mainly obtained.
[0036]
Further, when the change period is shortened, the change in the hue becomes faster, and when the change period is made longer, the change in the hue becomes slower. Further, if the phase of the color change at each vertex is shifted, an effect can be obtained in which the color change of the triangular polygon is not uniform in the surface and is glittering. Further, when the change width, period, and phase of the color data are changed randomly, a special effect is obtained in which the color change of the triangular polygon is also random.
[0037]
In the present embodiment, in order to express a state in which the stained glass shines on light, the color data is periodically changed as shown in FIGS. For example, the color data (R, G, B) of the three vertices of the polygon is set as color data as shown in FIG. For example, with respect to the vertex A, as shown in FIG. 5B, the color data (Ra, Ga, Ba) is changed in a sine wave shape with a predetermined width and a predetermined period around the set value. That is, as shown in FIG. 5B, the red data Ra, the green data Ga, and the blue data Ba are changed in a sinusoidal shape in synchronization with the same width and the same period for all three primary colors around the set value. . Thereby, the color of the vertex A changes in a sine wave shape with the set color as the center.
[0038]
As shown in the red data Ra of FIG. 5B, when the color setting value is close to the upper limit or the lower limit and the changing predetermined width is large, the upper end or the lower end of the change is flat.
[0039]
The other vertices B and C are also changed in a sine wave shape with the same width and the same period as the vertex A. At that time, as shown in FIG. 6, the width and the period are the same for each vertex, but the phases are shifted from each other. That is, the phase of the change of the red data Rb, the green data Gb, and the blue data Bb at the vertex B is shifted by 120 degrees with respect to the red data Ra, the green data Ga, and the blue data Ba at the vertex A. Similarly, the phase of change of red data Rc, green data Gc, and blue data Bc at vertex C is shifted by 120 degrees with respect to red data Rb, green data Gb, and blue data Bb at vertex B.
[0040]
When changed in this way, a state where a glass piece composed of triangular polygons shines on the sun is expressed.
[0041]
As described above, according to this embodiment, in addition to the state where the stained glass glitters, the shadow of the object changes due to the movement of the sun, the change in the reflection of light on the surface of the liquid, etc., and a colorful color such as a rainbow. Various images such as changes that cannot be expressed by conventional polygons can be displayed.
[0042]
In the above description, a specific example using a triangular polygon has been described. However, the present invention may be applied to other polygonal polygons without being limited to a triangular shape. Also, the data format of the polygon is not limited to that shown in FIG. 4, and other data formats may be used.
[0043]
(Two-player game using touch panel)
An image display of a two-player game using a touch panel in the game device of the present embodiment will be described with reference to FIGS.
[0044]
In the case of a game using a touch panel, the touch panel cannot detect a plurality of points at the same time, and only one point can be detected. Therefore, most of the games are performed by one player, and two or more players can participate.
