[0002]
[Prior art]
Many game systems have been proposed. A system composed of a home-use machine and a television monitor, a business-use machine, a personal computer or a system composed of a workstation, a display, and an audio output device. Each of these systems includes a controller for operation by the player, a recording medium on which game program data is recorded, a CPU that performs control for generating sound and images based on the game program data, and an image. It comprises a processor for generating, a processor for generating audio, a CRT for displaying images, and a speaker for outputting audio. As the recording medium, there are many CD-ROMs, semiconductor memories, cassettes incorporating semiconductor memories, and the like. The configuration of the game system is as described above.
[0003]
Next, the game screen configuration will be described. There are many types of games, but the game screen changes most roughly according to the operation of the controller, and changes adaptively depending on the operation object image and the operation state of the operation object. It consists of a background image. When this background image is further classified, it is used only to give a visual change to the game player, that is, it is used as a condition for obtaining a simple background and a result given to the game player, such as a score. Can be divided into An example of the latter is a background image of a course in a golf game, for example.
[0004]
Usually, in a golf game, an image showing a golf course and an image showing a golfer are displayed on the display surface of a television monitor, whereby a golf game space is formed on the display surface. Then, according to the operation of the controller by the game player, the golfer on the golf game space is visually moved, and a ball is hit by the club of the golfer. The hit ball visually flies in the depth direction in the golf game space. That is, in the golf game space, the same thing as golf actually performed by a human is visually performed. In simple terms, a golf game in a so-called video game is a golf game in which golf is visually performed by appropriately changing an image to be displayed on a television monitor according to the operation of a controller of a game player. is there.
[0005]
The golf course image is associated with the golf course height data. Then, how much the golf ball moves in the golf game space is calculated from the operation of the controller by the game player and the height data of the golf course, and the calculation result is displayed as an image. For example, if the golf player operates the controller so that the golf player hits the golf ball weakly toward a very high position in the golf game space when the golf ball is at a very low position in the green, The golf ball in the golf game space does not move to the position intended by the game player. The reason why the height data associated with each part of the course image is used is to give a game player playing a golf game a feeling closer to that of actual golf.

[0022]
Here, the form of the game system differs depending on the application. That is, when the game system is configured for home use, the television monitor 12 and the speaker 16 are separate from the game machine main body. When the game system is configured for business use, all the components shown in FIG. 1 are housed in a single casing. When the game system is configured with a personal computer or workstation as the core, the television monitor 12 corresponds to the display for the computer, and the drawing processor 10, the audio processor 13, The decompression circuit 7 corresponds to a part of program data recorded on the recording medium 30 or hardware on an expansion board mounted in an expansion slot of a computer, respectively, the interface circuit 4, the parallel port 8, and the The serial port 9 and the interface circuit 20 correspond to hardware on an expansion board mounted in an expansion slot of the computer. The buffers 11, 14, and 18 correspond to the areas of the main memory 5 or an expansion memory (not shown), respectively. In this embodiment, a case where the game system is configured for home use will be described as an example.
[0023]
Next, each component shown in FIG. 1 will be described in more detail. The graphics data generation processor 3 functions as a 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 based on the coordinate data of each vertex in the two-dimensional or three-dimensional plane of the image data supplied from the CPU 1, the movement amount data, and the rotation amount data. For example, a process of obtaining an address on the display area of the target image and returning the address data to the CPU 1 again, a process of calculating the luminance of the image according to the distance from the virtually set light source, and the like.

The decompression process includes a decoding process (decoding of data encoded by VLC: Variable Length Code), an inverse quantization process, an IDCT (Inverse Discrete Course Transform) process, an intra image restoration process, and the like.
[0026]
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 display area and a non-display area. The display area is a development area for data to be displayed on the display surface of the television monitor 12. The non-display 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 palette data is data for designating a color such as texture data. These data are stored in advance in the non-display area of the buffer 11 by the CPU 1 once from the recording medium 30 or divided into a plurality of times in accordance with the progress of the game.

One object is composed of a large number of polygons. The CPU 1 holds the coordinate data of each polygon in the three-dimensional space on the main memory 5. When the object is moved on the display surface by the operation of the controller 22, in other words, when expressing the movement of the object itself or changing the position (viewpoint position) where the object is viewed, the following processing is performed. Is called. That is, the CPU 1 gives the graphics data generation processor 3 the three-dimensional coordinate data of the vertices of each polygon, the movement amount data and the rotation amount data of each polygon stored in the main memory 5. The graphics data generation processor 3 sequentially converts the three-dimensional coordinate data after the movement and rotation of each polygon based on the three-dimensional coordinate data of the vertices of each polygon and the movement amount data and rotation amount data of each polygon. Ask. The three-dimensional coordinate data of each polygon thus obtained is converted into two-dimensional coordinate data, and the horizontal and vertical coordinate data is used as address data on the display area of the buffer 11, that is, polygon vertex address data. This is supplied to the drawing processor 10. The drawing processor 10 writes the texture data indicated by the pre-assigned texture address data on the triangular or quadrangular display area of the buffer 11 indicated by the 3 or 4 polygon vertex address data. As a result, an object in which texture data is pasted on a large number of polygons is displayed on the display surface of the television monitor 12.
[0032]
The drawing command for drawing a normal two-dimensional image includes vertex address data, texture address data, color palette address data indicating the storage position of the color palette data indicating the color of the texture data on the buffer 11, and the luminance of the texture. Brightness data shown. Among these data, the vertex address data is converted by the graphics data generation processor 3 from the vertex coordinate data on the two-dimensional plane from the CPU 1 based on the movement amount data and the rotation amount data from the CPU 1. It is the coordinate data obtained. Hereinafter, the drawing process is described in a simplified manner such as “issue a drawing command”.
[0033]
The audio processor 13 stores the ADPCM data read from the recording medium 30 in the buffer 14 and uses the ADPCM data stored in the buffer 14 as a sound source. Then, the voice processor 13 reads out ADPCM data with a clock having a frequency of 44.1 KHz, for example. The audio processor 13 performs processing such as pitch conversion, noise addition, envelope setting, level setting, and reverb addition on the ADPCM data read from the buffer 14. When the audio data read from the recording medium 30 is PCM data, it is converted into ADPCM data by the audio processor 13. Further, the processing by the program data for the PCM data is directly performed on the main memory 5. The PCM data processed on the main memory 5 is supplied to the audio processor 13 and converted into ADPCM data. After the above-described various processes are performed, the PCM data is output as audio from the speaker 16.

[0047]
F. Screen display example (Figure 5)
[0048]
FIG. 5 is an explanatory diagram showing a screen display example. As shown in FIG. 5, the basic screen includes an upper left and upper right character information display area, areas Ar2, Ar3, Ar4, a golfer Ma and its course display area (center in the figure), and a guide Gu1. Display area.
[0049]

Further, a character (WIND 4m) indicating wind force is displayed in a region directly below this area, and an image of an arrow By indicating the wind direction is displayed below the character.
[0050]
In addition, in the area Ar2, for example, titles of items to be set such as golf club selection, tee-up, and hitting position are displayed, and in the area Ar3, images of the items to be set (for example, golf clubs) are displayed. Is done. The guide Gu1 displays an instruction image In for indicating the flight distance and position of the golf ball. The display state of the instruction image In is changed at any time according to the setting. In the area Ar4, an image of the golf ball and the ground are displayed.
[0051]
In the center of the screen, an image of the golfer Ma having the golf club Cb and a course scenery such as green Gr are displayed. From the position of the golfer Ma (or the position of the ball) toward the hitting direction, A guide Gu2 is displayed. As shown in FIG. 3B, the guide Gu2 has a matrix shape on a two-dimensional plane, and is formed by a collection of a large number of straight lines. As shown in FIG. 5, the guide Gu2 is displayed in a pseudo three-dimensional manner so as to match the terrain from the position of the golfer Ma toward the batting direction, that is, similarly to the terrain. Further, the brightness of the guide Gu2 is varied according to the height of the terrain located below each part. In this example, the guide Gu2 is set to have a higher luminance as the height of the terrain just below it is higher, and the luminance is set to be lower as the height of the terrain directly below is lower. Thus, the game player can determine the level of the terrain. For example, when the batting setting is made by the controller 22, the game player carries the game according to the terrain in the golf game space, such as increasing the setting value. be able to.
[0052]
As already described, the guide Gu2 is formed by a large number of lines drawn by the drawing processor 10 shown in FIG. 1 between the vertices of the polygons constituting the terrain based on the line drawing command. Since the line drawing command includes luminance data of each polygon vertex, the drawing processor 10 determines the luminance of the line, the luminance of the polygon vertex corresponding to the start point, and the polygon vertex corresponding to the end point. Determine based on brightness. For example, when the luminance at the start point is higher than the luminance at the end point, the luminance of the line is determined such that the start point is the highest and gradually decreases as the end point is approached. On the other hand, when the luminance at the start point is lower than the luminance at the end point, the luminance of the line is determined such that the start point is the lowest and gradually increases as the end point is approached. In FIG. 5, for the sake of drawing, such gradation is not expressed within one line.
[0053]
As described with reference to FIGS. 3A and 4, height data is usually set for each part of the landscape. Then, the graphics data generation processor 3 shown in FIG. 1 performs light source calculation based on the height data and the position of the virtual light source based on the viewpoint position, and sets the brightness of each part according to the result. To do. Therefore, a certain distance and height can be expressed only by the scenery itself. However, the controller 22 cannot be appropriately operated when this is used as a guide only by expressing the distance and height in the course by the difference in luminance obtained by the light source calculation. Therefore, the guide Gu2 is displayed. According to this, each part of the guide Gu2 made of a straight line of the same length has brightness according to the height in the course and length according to the distance, so that the distance and height of the golf course can be understood more clearly. It can be expressed easily. Therefore, the game player can operate the controller 22 in accordance with the conditions of the golf course in the game space.
[0054]
G. Control by main routine (Figs. 6-8)
[0055]
6 to 8 are flowcharts for explaining the control operation by the main routine. Note that only step S1 is a control operation by the operating system stored in the ROM 6 shown in FIG. The other step is a control operation based on the game program data read from the recording medium 30. Further, as described above, the main body of control by the game program data is each means as a function of the CPU 1 shown in FIG.
[0056]
In step S <b> 1, the recording medium driver 19 reads the image, sound, and program data from the recording medium 30 according to an operating system command. Of the read data, the program data is stored in the main memory 5. Thus, the CPU 1 has the function shown in FIG. At this time, the image, that is, the texture data is stored in the buffer 11 of the rendering processor 10 and is assigned a texture number. The audio data is stored in the buffer 14 of the audio processor 13 and is assigned audio number data. Normally, not all image and audio data are held in the buffers 11 and 14 in step S1, but for convenience of explanation, it is assumed that all image and audio data are loaded in step S1.

In step S2, the button operation detection unit 1a determines whether or not the start button 22a of the controller 22 has been pressed. If “YES”, the process proceeds to step S3.
[0058]
In step S3, the drawing command issuing unit 1g issues a drawing command indicating drawing of the select image to the drawing processor 10 shown in FIG. The drawing processor 10 develops the image data of the selected image on the display surface of the buffer 11 based on the drawing command. Thereby, a select image is displayed on the display surface of the television monitor 12.
[0059]
In step S4, the button operating means 1a determines whether or not the start button 22a of the controller 22 has been pressed. If “YES”, the process proceeds to step S5.
[0060]
In step S5, the CPU 1 sets the selected game. Here, “selected” means that the game player selects a game using the cross key with reference to the selected image displayed in step S3, and then presses the start button 22a. . Here, the “game” includes, in addition to the game itself, for example, a character in a battle game. In short, it is a choice before the game is actually started.
[0061]
In step S6, the drawing command issuing unit 1g issues a drawing command indicating drawing of the initial image of the selected game to the drawing processor 10. As a result, the drawing processor 10 develops the image data of the initial image on the display area of the buffer 11. As a result, an initial image is displayed on the display surface of the television monitor 12.
[0062]
In step S7, the variable setting unit 1h resets the flags and variables held in the main memory 5, respectively.
[0063]
In step S8, the viewpoint position data setting unit 1b sets the values of the viewpoint position data Ex, Ey, Ez held in the main memory 5 to initial values. Here, the “initial value” is address data indicating the position of a tee ground Tg of a golf course, for example.
[0064]
In step S100, an image display process is performed. This image display processing routine will be described in detail later. In short, in this routine, images corresponding to the viewpoint position data Ex, Ey, Ez set in step S8 are displayed.
[0065]
In step S9, the computing means 1d adds variables Rx, Ry, Rz (not constant) to the viewpoint position data Ex, Ey, Ez, respectively. Here, the viewpoint position data Ex, Ey, Ez indicate a horizontal direction address, a vertical direction address, and a height, respectively.
[0066]
In step S10, the determination unit 1f determines whether or not the viewpoint position data Ey exceeds the maximum value EYmax. If “YES”, the process proceeds to step S11, and if “NO”, the process proceeds to step S100 again. . The loop consisting of the above steps S100 to S10 is for displaying the golf course so as to guide the game player by displaying the image by the image display processing routine S100 every time the value of the viewpoint position data is changed.
[0067]
In step S11, the viewpoint position data setting unit 1b sets initial values for the viewpoint position data Ex, Ey, and Ez, respectively.
[0068]
In step S100, an image display process is performed.
[0069]
In step S200, a tee-up setting process is performed. The tee-up setting processing routine S200 will be described in detail later. “Tee-up setting” means setting a tee shot position.
[0070]
In step S150, an unduration image output process is performed. The unduration image output routine S150 will be described in detail later. The unduration image is an image of the guide Gu2 described in FIG. As already described, the undulation image is a guide for making the distance and height of the course in the golf game space easier to understand. The guide Gu2 is set to have a higher brightness as the position corresponds to a higher place, and the length is shorter as the position corresponds to a far place. The other step S150 has the same contents.
[0071]
In step S250, camera position setting processing is performed. “Camera position” means an imaging position of a golf course and a golfer. This camera position setting processing routine S250 will be described in detail later.
[0072]
In step S300, a direction setting process is performed. “Direction” means the direction of the golfer's body. The direction setting routine S300 will be described in detail later.
[0073]
In step S12, the button operation detection unit 1a determines whether or not the fourth button 22f has been pressed. If “YES”, the process proceeds to step S350. This step S12 is a step of determining whether or not to end the direction setting by the direction setting routine S300. That is, as long as the game player does not press the fourth button 22f, the process proceeds to the direction setting routine S300, and thereafter, the display of the unduration image based on the direction setting value Di set in the direction setting routine S300 is This is performed in the duration image output routine S150.
[0074]
In step S350, a stance setting process is performed. “Stance” means a golfer's posture. The stance setting routine S350 will be described in detail later.
[0075]
In step S400, a club setting process is performed. “Club” means a golf club such as an iron or wood. The club setting routine S400 will be described in detail later.
[0076]
In step S450, hitting position setting processing is performed. The “striking position” means a position where the club head portion hits the golf ball. The impact position setting routine S450 will be described in detail later.
[0077]
In step S500, a batting process is performed. In this processing, image processing such as a hit golf ball and a background is mainly performed. The striking routine S500 will be described in detail later.
[0078]
In step S13, the determination unit 1f determines whether or not the last ball position is a hole position. If “YES”, the process proceeds to step S13, and if “NO”, the process proceeds to step S14. Here, the reason for determining whether or not the last ball position is the hole position is that it is necessary to change the subsequent processing depending on whether the cup-in is performed or not.
[0079]
In step S14, the drawing command issuing unit 1g issues a drawing command indicating drawing of the score image to the drawing processor 1g. Next, the result information setting unit 1 e supplies character data indicating the number of strokes to the drawing processor 10. Thereby, the drawing processor 1g develops the score image reflecting the result information on the display area of the buffer 11. As a result, a score image reflecting the result is displayed on the display surface of the television monitor 12. Thereafter, the process proceeds to step S3 again.
[0080]
In step S15, the result information setting unit 1e supplies character data indicating the flight distance to the last ball position to the drawing processor 10. Thus, the drawing processor 1g develops image data indicating the flight distance to the last ball position on the display area of the buffer 11. Thereby, the flight distance to the last ball position is displayed on the television monitor 12 as an image.
[0081]
In step S16, the viewpoint position data setting unit 1b substitutes the last ball position data Bxn, Byn, Bzn for the viewpoint position data Ex, Ey, Ez, respectively. Thereafter, the process proceeds to the image display processing routine S100 in step S100 again. As a result, an image with the last ball position as the viewpoint position is displayed.
[0082]
H. Control by image display routine S100 (FIGS. 9 to 10)
[0083]
9 to 10 are flowcharts for explaining the control operation by the image display routine S100.
[0084]
In step S101, the address setting means 1i sets the horizontal minimum address Xmin, the vertical minimum address Ymin, the horizontal maximum address Xmax, and the vertical maximum address Ymax of the golf course. Taking the golf course shown in FIG. 3 as an example, the minimum address is (0, 0) and the maximum address is (200, 530). Hereinafter, x and X mean a horizontal address, y and Y mean a vertical address, and z and Z mean a height.
[0085]
In step S102, the address acquisition unit 1j determines, based on the viewpoint position data Ex, Ey, Ez, the horizontal minimum address data ADxmin, the vertical minimum address data ADymin, and the horizontal maximum address data ADxmax within the display range. Data ADymax is obtained from the table shown in FIG. 4B. Here, the display range means the extraction area Ar1 as shown in FIG. 4A.
[0086]
In step S103, the variable setting unit 1h substitutes the minimum golf course address Xmin for the address data ADx.
[0087]
In step S104, the variable setting means 1h substitutes the minimum address data Ymin of the golf course for the address data ADy.
[0088]
In step S105, the height data correction unit 1k reads the height data z from the table.
[0089]
In step S106, the calculation means 1d subtracts the height data Ez from the height data z read in step S105 under the control of the height data correction means 1k. The height data z registered in the table is an initial value. The height data is based on the height at which the golf ball is placed. Therefore, the height data z registered in the table must be corrected as needed based on the height of the position where the golf ball is placed. Therefore, as shown in step S106, the height data Ez of the viewpoint position data is subtracted from the height data z read from the table.
[0090]
The viewpoint position data Ex, Ey, Ez are used before the first hit, but after the first hit, the viewpoint position data Ex, Ey, Ez includes the ball position. Data Bx, By, Bz is substituted. Therefore, before the first hit, the height data Ez of the viewpoint position data is subtracted from the height data z read from the table, but after the first hit, the ball position data Bz is subtracted from the height data z read from the table.
[0091]
In step S107, the height data correction unit 1k replaces the height data ADz obtained in step S106 with the height data z read from the table in the table in which the height data z is stored. Write to memory location. Thereby, the height data z read from the table is corrected to height data based on the viewpoint position data Ez.
[0092]
In step S108, the luminance processing unit 1q obtains luminance data Lu based on the value of the height data ADz.
[0093]
In step S109, the determination unit 1f determines whether or not the value of the luminance data Lu is larger than the maximum value Lumax of the luminance data Lu. If “YES”, the process proceeds to step S110, and “NO” is determined. If so, the process proceeds to step S111.
[0094]
In step S110, the luminance processing unit 1q substitutes the maximum value Lumax of the luminance data Lu for the luminance data Lu.
[0095]
In step S111, the determination unit 1f determines whether or not the value of the luminance data Lu is smaller than the minimum value Lumin of the luminance data Lu. If “YES”, the process proceeds to step S112, and “NO”. If so, the process proceeds to step S113.
[0096]
In step S112, the luminance processing unit 1q substitutes the minimum value Lumin of the luminance data Lu for the value of the luminance data Lu.
[0097]
In step S113, the luminance processing unit 1q rewrites the corresponding luminance data Lu with newly obtained luminance data Lu.
[0098]
In step S114, the computing means 1d adds “1” to the address data ADx.
[0099]
In step S115, the determination unit 1f determines whether or not the address data ADx is larger than the maximum address data Xmax. If “YES”, the process proceeds to step S116, and if “NO”, the process proceeds to step S119. .
[0100]
In step S116, the variable setting unit 1h substitutes the minimum address data ADxmin within the display range for the address data ADx.
[0101]
In step S117, the computing means 1d adds “1” to the address data ADy.
[0102]
In step S118, the determination unit 1f determines whether or not the address data ADy is larger than the maximum address data Ymax of the golf course. If “YES”, the image display processing routine S100 is exited, and “NO”. If there is, the process proceeds to step S119.
[0103]
On the other hand, in step S119, the determination unit 1f determines whether or not the address data ADx is not less than the minimum address data ADxmin in the display range and not more than the maximum address data ADxmax in the display range, and “YES”. If so, the process proceeds to step S120. If “NO”, the process proceeds to step S105 again.
[0104]
In step S120, the determination unit 1f determines whether the address data ADy is greater than or equal to the minimum address data ADymin within the display range and less than or equal to the maximum address data ADymax within the display range. If it is “NO”, the process proceeds to step S105 again.
[0105]
In step S121, the drawing command issuing unit 1g issues a drawing command to the drawing processor 10. As a result, the drawing processor 10 develops image data based on the viewpoint position data Ex, Ey, Ez on the display surface of the buffer 11. Therefore, the designated image is displayed on the display surface of the television monitor 12.
[0106]
I. Unduration image output routine S150 (FIGS. 11 to 12)
[0107]
11 and 12 are flowcharts for explaining the control operation by the unduration image output routine. As described above, the undulation image is determined by the game player by sensibly determining the distance and undulation on the golf course displayed on the display surface of the television monitor 12 and performing an appropriate operation based on this. It is a guide image for enabling to perform.
[0108]
In step S151, the button operation detection unit 1a determines whether or not the first button has been pressed. If “YES”, the process proceeds to step S152, and if “NO”, the unduration image output routine S150 is executed. Exit.
[0109]
In step S152, the unduration output determining unit 1m determines whether or not the unduration flag is “0”. If “YES”, the process proceeds to step S156, and if “NO”, the process proceeds to step S154. Here, the unduration flag is a flag indicating whether or not the guide Gu2 shown in FIG. 5 is displayed. For example, “1” is displayed and “0” is not displayed. In this step S152, when the unduration output determining means 1m determines that the unduration flag is “0”, the process proceeds to step S156 and subsequent steps, and an unduration image is output. In step S152, if the unduration output determination unit 1m determines that the unduration flag is “1”, the unduration image is deleted in steps S154 and S155.
[0110]
In step S154, the unduration output determination unit 1m sets the unduration flag to “0”.
[0111]
In step S155, the unduration image drawing unit 1n issues an unduration image deletion command to the drawing processor 10. As a result, the drawing processor 10 stops writing line data on the buffer 11. Thereby, the image of the guide Gu2 shown in FIG. 5 is erased from the display surface of the television monitor 12. Note that the erasure of the undulation image may be performed by rewriting an image other than the undulation image.
[0112]
In step S156, the unduration output determination unit 1m sets the unduration flag to “1”.
[0113]
In step S157, the address setting means 1i sets the minimum address data Xmin and Ymin and the maximum address data Xmax and Ymax of the golf course.
[0114]
In step S158, the address setting unit 1i obtains the minimum address ADxmin, ADymin, ADxmax, ADymax within the display range of the unduration image based on the ball position data Bx, By.
[0115]
In step S159, the variable setting unit 1h substitutes the minimum address data Xmin for the address data ADx.
[0116]
In step S160, the variable setting unit 1h substitutes the minimum address data Ymin for the address data ADy.
[0117]
In step S161, the height data correction unit 1k reads the height data z indicated by the address data ADx and ADy from the table.
[0118]
In step S162, the height data correction unit 1k subtracts the height data Ez from the height data z read in step S161 under the control of the height data correction unit 1k. The height data registered in the table is an initial value. The height data is based on the height at which the golf ball is placed. Therefore, the height data z registered in the table must be corrected as needed based on the height of the position where the golf ball is placed. Therefore, as shown in step S162, the viewpoint position data Ez is subtracted from the height data z read from the table.
[0119]
In step S163, the height data correcting unit 1k replaces the height data ADz obtained in step S162 with the height data z read from the table in the table in which the height data z is stored. Write to memory location. Thereby, the height data z read from the table is corrected to height data based on the viewpoint position data Ez.
[0120]
In step S164, the luminance processing unit 1q obtains the luminance data Lu based on the value of the height data ADz.
[0121]
In step S165, the determination unit 1f determines whether or not the value of the luminance data Lu is larger than the maximum value Lumax of the luminance data Lu. If “YES”, the process proceeds to step S110, and “NO” is determined. If so, the process proceeds to step S111.
[0122]
In step S166, the luminance processing unit 1q substitutes the maximum value Lumax of the luminance data Lu for the luminance data Lu.
[0123]
In step S167, the luminance processing unit 1q rewrites the corresponding luminance data Lu with the newly obtained luminance data Lu.
[0124]
In step S168, the computing means 1d adds “1” to the address data ADx.
[0125]
In step S169, the determination unit 1f determines whether the address data ADx is larger than the maximum address data Xmax. If “YES”, the process proceeds to step S170, and if “NO”, the process proceeds to step S173. .
[0126]
In step S170, the variable setting unit 1h substitutes the minimum address data ADxmin within the display range for the address data ADx.
[0127]
In step S171, the computing means 1d adds “1” to the address data ADy.
[0128]
In step S172, the determination means 1f determines whether or not the address data ADy is larger than the maximum address data Ymax of the golf course. If “YES”, the process exits the unduration image display routine S150.
[0129]
On the other hand, in step S173, the determination unit 1f determines whether the address data ADx is not less than the minimum address data ADxmin in the display range and not more than the maximum address data ADxmax in the display range, and “YES”. If so, the process proceeds to step S174, and if “NO”, the process proceeds to step S161 again.
[0130]
In step S174, the determination unit 1f determines whether the address data ADy is not less than the minimum address data ADymin in the display range and not more than the maximum address data ADymax in the display range. If it is “NO”, the process proceeds again to step S161.
[0131]
In step S175, the drawing command issuing unit 1g issues a line drawing command to the drawing processor 10. As a result, the drawing processor 10 writes line data on the display area of the buffer 11. Here, the guide Gu2 is image data in a matrix form as shown in FIG. 3B. However, since the image of the golf course is displayed in a pseudo three-dimensional manner according to the viewpoint position, the guide Gu2 is also displayed in a three-dimensional manner. Specifically, the guide Gu2 is drawn by connecting the vertices of the polygons of the golf course within the display range of the guide Gu2 with many lines. The luminance of the guide Gu2 is determined based on the height of each vertex of the polygon. One line is drawn by connecting a start point and an end point that coincide with the vertices of the polygon. The luminance of one line is expressed in a state where gradation is applied based on the luminance of the start point and the luminance of the end point, for example. As described above, when the height of the start point is higher than the height of the end point, the luminance gradually decreases from the start point to the end point, and when the height of the start point is lower than the height of the end point, the luminance Gradually increases from the start point to the end point.
[0132]
In step S176, the determination unit 1f determines whether or not the value of the luminance data Lu is smaller than the minimum value Lumin of the luminance data L. If “YES”, the process proceeds to step S177, and “NO” is determined. If so, the process proceeds to step S167.
[0133]
In step S177, the luminance processing unit 1q substitutes the minimum value Lumin of the luminance data Lu for the luminance data Lu.
[0134]
The height data is corrected by the processing in steps S161 to S163, and thereafter, the address data ADx and ADy are within the minimum addresses ADxmin, ADymin, ADxmax, and ADymax within the display range of the unduration image. The drawing process is repeatedly performed. By this processing, an image of the guide Gu2 is displayed on the television monitor 12.
[0135]
[Effects of displaying an unduration image]
In order for the game player to cause a golfer in the golf game space to make a shot, it is necessary to perform a predetermined operation on the controller 22. The operation mode will be described in detail. The moving distance of the golf ball in the golf game space varies depending on the operation state of the controller 22. As shown in FIG. 5, the distance and terrain in the golf game space are set for the golf course in the golf game space. For example, the golf course shown in FIG. 5 has a length of 518 yards, and is set to have a bunker or undulation in the middle. The game player operates the controller 22 based on such information.
[0136]
By the way, when the ball is hit at a relatively close place such as rolling the golf ball, it is necessary to display the distance and the undulation more easily. The distance here means a sense of distance given to the game player. This is because the game player can operate the controller 22 according to the distance and the undulations as described above. The distance and undulation of the golf course are expressed by the color and brightness of the displayed image. The brightness and darkness of the golf course image itself is expressed by the color and luminance information obtained by the graphics data generation processor 3 shown in FIG.
[0137]
However, it is difficult for the game player to recognize the undulation and distance of the golf course only by the color and brightness of the golf course. This is because a very large object such as a golf course is actually expressed within a very narrow range such as the display surface of the television monitor 12. In other words, it is difficult for a game player who knows the actual size, distance, and undulations to recognize the size, distance, and undulations in the game space only by color and brightness.
[0138]
Therefore, in this embodiment, as shown in FIG. 5, the guide Gu2 is displayed so as to be superimposed on the terrain formed in the game space. As already described, this guide Gu2 is displayed by a line drawing command. The shape of the guide Gu2 is a matrix as shown in FIG. 3B. As shown in FIG. 5, when displaying on the terrain, the length of the line constituting the guide Gu2 is changed according to the distance from the viewpoint position and the position. Moreover, the luminance of the guide Gu2 is changed based on the luminance data Lu of the terrain on which the guide Gu2 is displayed. Therefore, it is possible to accurately give a sense of distance and undulation information in the game space to the game player, so that the game player can further operate the controller 22 according to the displayed golf course. There is a big merit that it can be done accurately.
[0139]
J. et al. Control by tee-up setting routine S200 (FIGS. 13 to 14)
[0140]
13 and 14 are flowcharts for explaining the control operation by the tee-up setting routine S200. Here, the setting of the tee-up means setting of the position of the tee shot.
[0141]
In step S <b> 201, the drawing command issuing unit 1 g issues a drawing command indicating drawing of the guidance image to the drawing processor 10. The drawing processor 10 expands the guidance image data on the display area of the buffer 11. Thereby, a guidance image for setting tee-up is displayed in the area Ar3 on the display surface of the television monitor 12 shown in FIG. 5, and a guide Gu1 is displayed in the right area.
[0142]
In step S202, the drawing command issuing unit 1g issues a line drawing command corresponding to the initial value to the drawing processor 10. The drawing processor 10 writes line data from the start point address to the end point address on the buffer 11 in response to the line drawing command. This line is the instruction image In on the guide Gu1 shown in FIG. The guide Gu1 is a reduced image of the currently selected golf course. Therefore, the game user can predict the trajectory, the flight distance, and the stop position of the golf ball when the golf player hits the golf player Ma in the golf game space through the controller 22 with the current setting.
[0143]
In step S203, the button operation detection unit 1a determines whether or not the cross key is pressed. If “YES”, the process proceeds to step S204.
[0144]
In step S204, the button operation detection unit 1a determines whether or not the right key R is pressed. If “YES”, the process proceeds to step S209, and if “NO”, the process proceeds to step S205.
[0145]
In step S205, the button operation detection unit 1a determines whether or not the left key L is pressed. If “YES”, the process proceeds to step S206, and if “NO”, the process proceeds to step S203 again.
[0146]
In step S206, the computing means 1d subtracts “1” from the tee-up setting value Ty.
[0147]

[0151]
In step S211, the variable setting unit 1h substitutes the minimum value Tymin of the tee-up setting value for the tee-up setting value Ty.
[0152]
In step S212, the drawing command issuing unit 1g issues a drawing command indicating drawing of a tee-up image corresponding to the value of the tee-up setting value Ty to the drawing processor 10. As a result, the image on the area Ar3 shown in FIG. 5 is displayed according to the value of the tee-up setting value Ty.
[0153]
In step S213, the drawing command issuing unit 1g issues a line drawing command to the drawing processor 10. As a result, the drawing processor 10 writes line data on the buffer 11 from the start point address to the end point address. Therefore, the line In on the guide Gu1 on the display surface of the television monitor 12 is also in a display state according to the value of the tee-up setting value Ty.
[0154]
In step S214, the button operation detection unit 1a determines whether or not the fourth button 22f has been pressed. If “YES”, the process proceeds to step S215, and if “NO”, the process proceeds to step S203 again.
[0155]
In step S215, the parameter management unit 1o stores the tee-up set value data Ty in the main memory 5.
[0156]
K. Control by camera position setting routine S250 (FIGS. 15 to 16)
[0157]
15 and 16 are flowcharts for explaining the control operation by the camera position setting routine S250. In this embodiment, as the camera position, the back, front, left side, right side, etc. of the golf player Ma can be set in the game space. The camera position setting value indicating the camera position is viewpoint position data. Therefore, viewpoint position data corresponding to the camera position setting value is selected, and an image corresponding to the viewpoint position data is output. The camera position setting value is incremented or decremented each time the right key R or the left key L of the cross key is pressed once.
[0158]
In step S251, the button operation detection unit 1a determines whether or not the cross key is pressed. If “YES”, the process proceeds to step S252.

[0161]
In step S254, the calculation unit 1d subtracts “1” from the camera position setting value Ca.

[0243]
Here, the guide Gu3 will be described. When the game player operates the controller to cause the golfer Ma in the golf game space to perform a hit, the guide Gu3 indicates how much the hitting strength (hereinafter referred to as “energy”) by his / her operation is. This is an image for showing to the game player. As shown in FIG. 3D, the guide Gu3 has a shape in which a donut-shaped figure is partially cut away.

When the fourth button 22f is pressed while the guide Gu3 is displayed, the inside of the guide Gu3 is sequentially filled from the min position of the guide Gu3 toward the max position. At this time, it is painted in a predetermined amount, such as yellow, light blue, blue, purple, and red. The tip of the filled portion indicates the energy of hitting at that time. Therefore, the longer the time that the fourth button 22f is pressed, the greater the energy of hitting.
[0245]
On the other hand, when the fourth button 22f is released in the above state, the filled portions of the guide Gu3 disappear sequentially from that point. In the case of the above example, the filled portions disappear in the order of red, purple, blue, light blue, and yellow from the position of max of the guide Gu3 toward the position of min. The tip of the filled portion indicates the energy of hitting at that time. Therefore, the longer the time for which the fourth button 22f is released, the smaller the energy of hitting. When the fourth button 22f is pressed again after the fourth button 22f is released, the energy of hitting at that time is determined. When the energy of the hit is fixed, the hit is made.

[0251]
In step S507, the drawing command issuing unit 1g supplies the drawing processor 10 with a line drawing command corresponding to the value of the hit energy data POWER. Here, the line drawing command means that a line is drawn with a specified color from the outer periphery to the inner periphery (or from the inner periphery to the outer periphery) of the guide Gu3 shown in FIG. 3D. Based on the line drawing command, the drawing processor 10 writes line data on the guide Gu3 written in the buffer 11 as much as the value of the impact energy data POWER.

Thereby, the inside of the guide Gu3 displayed on the display surface of the television monitor 12 is filled with a predetermined color. Note that the filling in the guide Gu3 in step S510 has a smaller value of the impact energy data POWER, so that the painted area gradually decreases on the display surface of the television monitor 12. Looks like going.
[0255]
In step S511, the button operation detection unit 1a determines whether or not the fourth button 22f has been pressed.

In step S514, the calculation means 1d determines that the ball position Bx, By, Bz, impact energy data POWER, tee-up data Ty, direction data Di, stance data St, club number data NO, address data Had and Vad, and wind direction data WDi. Based on the wind power data Wp, all ball positions Bx, By, Bz per unit time are obtained. Here, the unit time is, for example, 30 frames / second in the NTSC television system. Therefore, in this case, the position of the ball for each frame is obtained in advance.

The time until the ball stops depends on the above parameters. Therefore, if the position of the ball for each frame is obtained and an image corresponding to the position of the ball is displayed for each frame, the number of frames until the ball stops is also different. The number of frames until the ball stops is stored in the main memory 5 as nmax.
