DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game system using an optical disk, a magnetic disk, a cassette type recording medium using a semiconductor memory, etc., on which a program data is recorded. The present invention relates to a method of displaying a height, a guide display method in a game system using terrain information, a game system, and a recording medium.

[0002]

2. Description of the Related Art Many game systems have been proposed. Examples of the system include a home dedicated machine and a television monitor, a professional dedicated machine, and a system including a personal computer or a workstation, a display, and an audio output machine. In each of these systems, a controller for a player to operate, a recording medium on which game program data is recorded, a CPU for controlling sound and image generation 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.

Next, the screen configuration of the game will be described. Although there are many types of games, the screen of the game is adaptively changed according to the operation target image, which is changed based on the operation of the controller, and the stationary state or the operation state of the operation target. And a background image.
When this background image is further classified, those used only to give a visual change to the game player, that is, those used as mere background and those used as conditions for obtaining a result given to the game player, for example, a score, etc. Can be divided into An example of the latter is, for example, a background image of a course in a golf game.

Normally, in a golf game, an image showing a golf course and an image showing a golfer are displayed on a display surface of a television monitor, so that a golf game space is formed on the display surface. Then, in response to the operation of the controller by the game player, the golfer in the golf game space is visually moved, and a ball is hit by the club owned by 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. Briefly, a golf game in a so-called video game is a game in which golf is visually performed by appropriately changing an image displayed on a screen of a television monitor in accordance with an operation of a controller of a game player. is there.

[0005] The image of the golf course is associated with the height data of the golf course. Then, from the operation of the controller by the game player and the height data of the golf course, how much the golf ball moves in the golf game space is calculated, and the calculation result is displayed as an image. For example, if the golf player is in a very low position in the green and the game player operates the controller so that the golfer in the golf game space hits the golf ball lightly toward a very high position, The golf ball in the golf game space does not move to the position intended by the game player. The reason why the elevation data associated with each part of the course image is used is to give a game player who plays a golf game a sense closer to actual golf.

[0006]

By the way, in a game such as the above-mentioned golf game in which elevation data is associated with each position in the background, a course is required to allow a game player to perform an appropriate operation. It is necessary to display the height correctly. If the height of the course is not expressed in any way, the game player cannot properly operate the controller.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points. In a game in which elevation data is associated with each vertex of the background, the game player can easily and accurately operate the game player. The purpose is to guide.

[0008]

One of the main inventions is to display on a display surface of display means at least image information indicating a terrain at which the height of a vertex is set, and to display the image information of the terrain. A line is displayed between any vertices that exist within the predetermined range, and the brightness of each line is represented by the relationship between the height of the top of the terrain information corresponding to the start point of each line and the height of the top of the terrain information corresponding to the end point. This is a distance / height expression method in a display space, which is set in accordance with the distance.

The drawing processor 10 performs a drawing process on the buffer 11 based on a drawing command issued by the CPU 1. The buffer 11 has a display area and a non-display area. The display area is an area where data to be displayed on the display surface of the television monitor 12 is expanded. The non-display area is a storage area for texture data, color palette data, and the like. Here, the texture data is 2

Further, the luminance data is calculated by the graphics data generation processor 3 based on the distance from the position indicated by the polygon vertex coordinate data after the coordinate conversion from the CPU 1 to the virtually arranged light source.
It is determined.

The polygon vertex address data indicates an address on the display area of the buffer 11. The drawing processor 10 writes the corresponding texture data in the range of the display area of the buffer 11 indicated by three or four polygon vertex address data. This process is generally called "pasting texture".

One object is composed of many polygons. The CPU 1 stores, in the main memory 5, coordinate data of each polygon in a three-dimensional space. When the object is moved on the display surface by the operation of the controller 22, in other words, when the movement of the object itself is expressed or the position at which the object is viewed (viewpoint position) is changed, the following processing is performed. Will be That is, the CPU 1 provides the graphics data generation processor 3 with the three-dimensional coordinate data of the vertices of each polygon held in the main memory 5 and the movement amount data and rotation amount data of each polygon. The graphics data generation processor 3
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, three-dimensional coordinate data after movement and rotation of each polygon are sequentially obtained. The three-dimensional coordinate data of each polygon obtained in this manner is converted into two-dimensional coordinate data, and the horizontal and vertical coordinate data are used as address data on the display area of the buffer 11, that is, as polygon vertex address data. It is supplied to the drawing processor 10. The drawing processor 10 writes texture data indicated by texture address data allocated in advance on a triangular or quadrangular display area of the buffer 11 indicated by three or four polygon vertex address data. As a result, on the display surface of the television monitor 12, an object in which texture data is pasted on a large number of polygons is displayed.

A 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 texture data. And luminance data indicating the luminance of the image. Of these data, the vertex address data is used by the graphics data
Vertex coordinate data on a two-dimensional plane from the CPU 1 is coordinate data obtained by performing coordinate conversion based on movement amount data and rotation amount data from the CPU 1. Less than,

In the center of the screen, a golf club Cb
The image of the golfer Ma having, and the scenery of the course such as green Gr are displayed, and from the position of the golfer Ma (or the position of the ball) in the hitting direction,
The guide Gu2 is displayed. This guide Gu2 is shown in FIG.
As shown in B, it has a matrix-like shape on a two-dimensional plane, and is formed by a group of many 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 in the hitting direction, that is, similarly to the terrain. Further, the brightness of the guide Gu2 is variable according to the height of the terrain located below each part. In this example, the brightness of the guide Gu2 is set to be higher as the height of the terrain immediately below it is higher, and the brightness is set to be lower as the height of the terrain immediately below is lower. Thereby, the game player can determine the level of the terrain, and when carrying out a hit setting with the controller 22, for example, performs a game carrying operation according to the terrain in the golf game space, such as increasing the set value. be able to.

As described above, the guide Gu2 is used.
Is formed by a number of lines drawn by the drawing processor 10 shown in FIG. 1 based on the line drawing command between the vertices of the polygons constituting the terrain. Since the line drawing instruction includes the luminance data of each polygon vertex, the drawing processor 10 calculates the luminance of the line as the luminance of the vertex of the polygon corresponding to the start point and the luminance of the vertex of the polygon corresponding to the end point. Determined based on luminance. 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 so as to be the highest at the start point and to gradually decrease as approaching the end point. 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 so that the luminance at the start point is the lowest and gradually increases as approaching the end point. In FIG. 5, such gradation is not represented inside one line for the sake of drawing.

As described with reference to FIGS. 3A and 4, height data is usually set for each part of the scenery. Then, the graphics data generation processor 3 shown in FIG. 1 performs a light source calculation based on the height data and the position of the virtual light source based on the viewpoint position, and sets the luminance of each unit according to the result. I do. Therefore, it is possible to express a certain distance and height by the scenery itself. However, simply expressing the distance and height within the course by the difference in luminance obtained by the light source calculation does not allow the controller 22 to be properly operated when this is used as a guide. Therefore, the guide Gu2 is displayed.
According to this, since each portion of the guide Gu2 formed of a straight line of the same length has a brightness corresponding to the height in the course and a length corresponding to the distance, the distance and the height of the golf course can be more clearly understood. It can be easily expressed. Therefore, the game player can operate the controller 22 in accordance with the conditions of the golf course in the game space.

G. Control by main routine (Figs. 6 to 8)

FIGS. 6 to 8 are flowcharts for explaining the control operation according to the main routine. Note that only step S1 is a control operation by the operating system stored in the ROM 6 shown in FIG. Another step is a control operation based on the game program data read from the recording medium 30. Further, as described above, the subject of control based on the game program data is each unit as a function of the CPU 1 shown in FIG.

In step S 1, the recording medium driver 19 reads out images, sounds, and program data from the recording medium 30 in accordance with an instruction from the operating system.
Of the read data, the program data is stored in the main memory 5. As a result, the CPU 1
Has the functions shown in FIG. At this time, it is assumed that the image, that is, the texture data is stored in the buffer 11 of the drawing processor 10, and a texture number is assigned to each. The audio data is stored in the buffer 14 of the audio processor 13, and audio number data is assigned to each. Normally, all image and audio data are stored in the buffers 11 and 1 in step S1.

In step S2, the button operation detecting means 1
It is determined whether or not the start button 22a of the controller 22 has been pressed, and if "YES", the process proceeds to step S3.

In step S3, the drawing command issuing means 1g
Issues a drawing command indicating the drawing of the selected 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. As a result, the selected image is displayed on the display surface of the television monitor 12.

In step S4, the button operation means 1a
Determines whether the start button 22a of the controller 22 has been pressed, and if "YES", the process proceeds to step S5.

At step S5, the CPU 1 sets the selected game. Here, "selected" means that the game player refers to the selected image displayed in step S3, selects a game using the cross key, and then presses the start button 22a. . Here, the “game” includes not only the game itself but also, for example, characters in a fighting fighting game. In short, it is a choice before the game is actually started.

In step S6, the drawing command issuing means 1g
Issues a drawing command to the drawing processor 10 indicating the drawing of the initial image of the selected game. Thereby, the rendering processor 10 develops the image data of the initial image on the display area of the buffer 11. Thus, the initial image is displayed on the display surface of the television monitor 12.

In step S7, the variable setting means 1h
The flags and variables held in the main memory 5 are reset.

In step S8, the viewpoint position data setting means 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, for example, address data indicating the position of the tee ground Tg of the golf course.

In step S100, an image display process is performed. This image display processing routine will be described later in detail. In short, in this routine, an image corresponding to the viewpoint position data Ex, Ey, Ez set in step S8 is displayed.

In step S9, the calculating means 1d adds the variables Rx, Ry, Rz to the viewpoint position data Ex, Ey, Ez.
(Not constant) are added. Here, the viewpoint position data Ex, Ey, and Ez indicate a horizontal address, a vertical address, and a height, respectively.

In step S10, the determining means 1f determines whether or not the viewpoint position data Ey has exceeded the maximum value EYmax. If "YES", the flow shifts to step S11.
If “NO”, the process returns to step S100. The loop consisting of steps S100 to S10 is executed every time the value of the viewpoint position data is changed.
By displaying the image by 100, the golf course
This is for displaying to guide the game player.

In step S11, the viewpoint position data setting means 1b sets initial values for the viewpoint position data Ex, Ey, and Ez, respectively.

In step S100, an image display process is performed.

In step S200, a tee-up setting process is performed. This tee-up setting processing routine S20
0 will be described in detail later. “Tee-up setting” means setting of a tee shot position.

In step S150, an undulation image output process is performed. The undulation image output routine S150 will be described later in detail. The undulation image is an image of the guide Gu2 described with reference to FIG. As described above, the undulation image is a guide for making it easier to understand the distance and height of the course in the golf game space. This guide G
As for u2, the brightness is set higher at a position corresponding to a higher place, and the length is displayed shorter at a position corresponding to a distant place. The other steps S150 have the same contents.

In step S250, a camera position setting process is performed. The “camera position” means an imaging position of a golf course and a golfer. The camera position setting processing routine S250 will be described later in detail.

In step S300, a direction setting process is performed. "Direction" means the orientation of the golfer's body.
The direction setting routine S300 will be described later in detail.

In step S12, the button operation detecting means 1a determines whether or not the fourth button 22f has been pressed.
If “YES”, the process moves 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 undulation image based on the direction setting value Di set in the direction setting routine S300 is displayed as an undulating image. This is performed in the duration image output routine S150.

In step S350, a stance setting process is performed. "Stance" refers to the golfer's attitude. This stance setting routine S350 will be described later in detail.

In step S400, a club setting process is performed. “Club” means a golf club such as an iron or wood. This club setting routine S400

At step S500, a striking process is performed. In this processing, image processing of a hit golf ball, a background, and the like is mainly performed. This striking routine S50
0 will be described in detail later.

In step S13, the judging means 1f judges whether or not the last ball position is a hole position.
If "S", the process proceeds to step S13, and if "NO", the process proceeds to step S14. The reason for determining whether or not the last ball position is the hole position is that the subsequent processing needs to be changed depending on whether the cup is in or not.

In step S14, the drawing command issuing means 1
g issues a rendering command indicating rendering of the score image to the rendering processor 1g. Next, the result information setting means 1e supplies character data indicating the number of strokes and the like to the drawing processor 10. Thereby, the rendering processor 1g stores the score image reflecting the result information in the buffer 1
1 is expanded on the display area. As a result, a score image on which the result is reflected is displayed on the display surface of the television monitor 12. Then, after this, step S3 is performed again.
Move to

In step S15, the result information setting means 1e
Supplies character data indicating the flight distance to the last ball position to the drawing processor 10. This allows
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.

In step S16, the viewpoint position data setting means 1b outputs the last ball position data Bxn, Byn,
Bzn is substituted into viewpoint position data Ex, Ey, and Ez, respectively. Thereafter, the process returns to the image display processing routine S100 in step S100. As a result, an image in which the last ball position is the viewpoint position is displayed.

H. Control by Image Display Routine S100 (FIGS. 9 to 10)

FIGS. 9 and 10 show an image display routine S10.

In step S101, the address setting means 1i sets the minimum horizontal address Xmi of the golf course.
n, a vertical minimum address Ymin, a horizontal maximum address Xmax, and a vertical maximum address Ymax are set. Taking the golf course shown in FIG. 3 as an example, the minimum address is (0, 0) and the maximum address is (200, 5,
30). Hereinafter, x and X mean a horizontal address, y and Y mean a vertical address, and z and Z mean a height.

In step S102, the address acquisition means 1j determines the minimum horizontal address data ADxmin, ADxmin, within the display range based on the viewpoint position data Ex, Ey, Ez.
The vertical minimum address data ADymin and the horizontal maximum address data ADxmax are obtained from the table shown in FIG. 4B. Here, the display range means the extraction area Ar1 as shown in FIG. 4A.

In step S103, the variable setting means 1h

In step S105, the height data correcting means 1k reads the height data z from the table.

In step S106, under the control of the height data correcting means 1k, the calculating means 1d executes the processing in step S10.
The height data Ez is subtracted from the height data z read in step 5. The height data z registered in the table is
This is the 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.

Note that the viewpoint position data Ex, Ey, and Ez are used before the first one is hit, but after the first one is hit, the viewpoint position data Ex, Ey, and Ez are included in the viewpoint position data Ex, Ey, and Ez. ,
The ball position data Bx, By, Bz are 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 Ez is subtracted. Bz is the height data z read from the table
Is subtracted from

In step S107, the height data correcting means 1k outputs the height data A obtained in step S106.
Dz is written to the storage location of the table in which the height data z was stored, instead of the height data z read from the table. Thus, the height data z read from the table is corrected to height data based on the viewpoint position data Ez.

In step S108, the luminance processing means 1q

In step S112, the luminance processing means 1q
Is the minimum value Lu of the luminance data Lu in the value of the luminance data Lu.
Substitute min.

In step S113, the luminance processing means 1q
Rewrites the corresponding luminance data Lu with the newly obtained luminance data Lu.

In step S114, the calculating means 1d
"1" is added to the address data ADx.

In step S115, the judgment means 1f
It is determined whether or not the address data ADx is larger than the maximum address data Xmax. If "YES", the process shifts to the step S116, and if "NO", the process proceeds to a step S11.
Move to 9.

In step S116, the variable setting means 1h
Substitutes the minimum address data ADxmin within the display range for the address data ADx.

In step S117, the calculating means 1d sets
"1" is added to the address data ADy.

In step S118, the judgment means 1f
It is determined whether or not the address data ADy is larger than the maximum address data Ymax of the golf course, and “YE
If "S", the process exits the image display processing routine S100, and if "NO", the process moves to step S119.

On the other hand, in step S119, the judgment means 1
It is determined whether or not f is equal to or more than the minimum address data ADxmin in the display range and equal to or less than the maximum address data ADxmax in the display range. If “YES”, the process proceeds to step S120. ,

In step S120, the judging means 1f
It is determined whether the address data ADy is equal to or greater than the minimum address data ADymin in the display range and equal to or less than the maximum address data ADymax in the display range.
If “YES”, the process shifts to step S121 to “N
If "O", the process returns to step S105.

In step S121, the drawing command issuing means 1g issues a drawing command to the drawing processor 10. Thereby, the drawing processor 10 converts the image data based on the viewpoint position data Ex, Ey, Ez into
The image is developed on the display surface of the buffer 11. Therefore, the designated image is displayed on the display surface of the television monitor 12.

I. Undulation image output routine S150 (FIGS. 11 to 12)

FIGS. 11 and 12 are flowcharts for explaining the control operation in the undulation image output routine. As described above, the undulation image allows the game player to intuitively determine the distance or undulation on the golf course displayed on the display surface of the television monitor 12 and perform an appropriate operation based on this. This is a guide image for enabling the user to perform the operation.

In step S151, the button operation detecting means 1a determines whether or not the first button has been pressed.
If “ES”, the process proceeds to step S152, and if “NO”, the undulation image output routine S15

In step S152, the undulation output determining means 1m determines whether or not the undulation flag is "0". If "YES", the process proceeds to step S152.
The process moves to 156, and if “NO”, the process moves to step S154. Here, the undulation flag is set as shown in FIG.
Is a flag indicating whether or not the guide Gu2 shown in (1) is displayed. For example, "1" is displayed and "0" is not displayed. In this step S152, when the undulation output determining means 1m determines that the undulation flag is "0", the process proceeds to step S156 and the undulation image is output. Also, in this step S152, when the undulation output determining means 1m determines that the undulation flag is "1",
In steps S154 and S155, the undulation image is deleted.

In step S154, the undulation output determining means 1m sets the undulation flag to "0".

In step S155, the undulation image drawing means 1n issues an erasure image deletion command to the drawing processor 10. As a result, the rendering processor 10 stops writing line data to the buffer 11. Thus, the image of the guide Gu2 shown in FIG. 5 is erased from the display surface of the television monitor 12. The erasing of the undulation image may be performed by rewriting an image other than the undulation image.

In step S156, the undulation output determining means 1m sets the undulation flag to "1".

In step S157, the address setting means 1i sets the minimum address data Xmin,
Ymin and maximum address data Xmax, Ymax

The height data z indicated by is read.

At step S162, under the control of the height data correcting means 1k, the height data correcting means 1k causes the calculating means 1d to convert the height data Ez from the height data z read at step S161. Subtract. 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.

In step S163, the height data correcting means 1k outputs the height data A obtained in step S162.
Dz is written to the storage location of the table in which the height data z was stored, instead of the height data z read from the table. Thus, the height data z read from the table is corrected to height data based on the viewpoint position data Ez.

In step S164, the luminance processing means 1q
Obtains the luminance data Lu based on the value of the height data ADz.

At step S165, the judgment means 1f
The value of the luminance data Lu is the maximum value Lum of the luminance data Lu.

It is determined whether or not the address data ADy is larger than the maximum address data Ymax of the golf course, and “YE
If "S", the process exits the undulation image display routine S150.

On the other hand, in step S173, the judgment means 1
It is determined whether or not f is equal to or more than the minimum address data ADxmin in the display range and equal to or less than the maximum address data ADxmax in the display range. If “YES”, the process proceeds to step S174. ,
If "NO", the process returns to step S161.

At step S174, the judgment means 1f
It is determined whether the address data ADy is equal to or greater than the minimum address data ADymin in the display range and equal to or less than the maximum address data ADymax in the display range.
If “YES”, the flow shifts to the step S175, and “N”
If "O", the process returns to step S161.

At step S175, the drawing command issuing means 1g issues a line drawing command to the drawing processor 10. Thereby, the rendering processor 10
The line data is written on the display area of the buffer 11. Here, the guide Gu2 is, as shown in FIG. 3B,
This is matrix image data. However, since the image of the golf course is pseudo-three-dimensionally displayed according to the viewpoint position, the guide Gu2 is also three-dimensionally displayed. 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 a number of lines. And guide Gu
The luminance of 2 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 match the vertices of the polygon. The luminance of one line is expressed in a gradation state, for example, based on the luminance at the start point and the luminance at the end point. 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 decreases. Gradually increases from the start point to the end point.

At step S176, the judgment means 1f
The value of the luminance data Lu is the minimum value Lumi of the luminance data L
It is determined whether it is smaller than n or not. If “YES”, the process shifts to the step S177.
It moves to 167.

In the step S177, the luminance processing means 1q
Is the minimum value Lumi of the luminance data Lu in the luminance data Lu.
Substitute n.

Steps S161 to S163
The height data is corrected by the above processing, and thereafter, the address data ADx and ADy are converted to the minimum addresses ADxmin and ADymi within the display range of the undulation image.
Within the range of n, ADxmax, ADymax,
The drawing process is repeatedly performed. By this processing, the image of the guide Gu2 is displayed on the television monitor 12.

[Effect by Displaying Undulation Image] In order for a game player to make a golfer in a golf game space 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 the 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.

By the way, when a golf ball is hit at a relatively close place, such as when rolling a golf ball, it is necessary to display the distance and the undulation more easily. The distance here means a sense of distance that is given to the game player. As described above, this is for enabling the game player to operate the controller 22 according to the distance and the undulation. The distance and the undulation of the golf course are represented by the color and brightness of the displayed image.
The brightness of the image of the golf course itself is expressed by the color and luminance information obtained by the graphics data generation processor 3 shown in FIG.

However, it is difficult for the game player to recognize the undulation and the distance of the golf course only by the color and the brightness of the Golulu course. This is because a very large object such as a golf course is actually represented 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 undulation to recognize the size, distance, and undulation in the game space only by color and luminance.

Therefore, in the present embodiment, as shown in FIG. 5, the guide Gu2 is displayed so as to overlap the terrain formed in the game space. As already described, this guide Gu2 is displayed by the line drawing command. The shape of the guide Gu2 is a matrix as shown in FIG. 3B. Then, as shown in FIG. 5, when displaying on the terrain, the guide Gu2
Is changed in accordance with the distance and the position from the viewpoint position. And the guide Gu
The luminance of No. 2 is changed based on the luminance data Lu of the terrain where the guide Gu2 is displayed. Therefore, a sense of distance and undulation information in the game space can be accurately given to the game player.
There is a great merit that the game player can more accurately operate the controller 22 according to the displayed golf course.

J. Control by tee-up setting routine S200 (FIGS. 13 and 14)

FIGS. 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 the setting of the position of the tee shot.

In step S202, the drawing command issuing means 1g issues a line drawing command corresponding to the initial value to the drawing processor 10. Drawing processing processor 10
Writes line data from the start address to the end 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. And guide G
u1 is a reduced image of the currently selected golf course. Therefore, the game user can predict the trajectory, flight distance, and stop position of the golf ball when the golf ball is hit by the golf player Ma in the golf game space via the controller 22 with the current settings.

In step S203, the button operation detecting means 1a determines whether or not the cross key has been pressed.

If it is, the process proceeds to step S208, and if “NO”, the process proceeds to step S212.

At step S208, the variable setting means 1h
Substitutes the maximum value Tymax of the tee-up set value into the tee-up set value Ty.

In step S209, the calculating means 1d sets
"1" is added to the tee-up set value Ty.

Thus, the image on the area Ar3 shown in FIG. 5 is in a display state according to the value of the tee-up set value Ty.

In step S213, the drawing command issuing means 1g issues a line drawing command to the drawing processor 10. Thereby, the rendering processor 10
Line data is written on the buffer 11 from the start address to the end address. Therefore,
The line In on the guide Gu1 on the display surface of the television monitor 12 also has a display state corresponding to the tee-up set value Ty.

In step S214, the button operation detecting means 1a determines whether or not the fourth button 22f has been pressed. If "YES", the flow shifts to step S215.
If "NO", the process returns to step S203.

In step S215, the parameter management means 1o stores the tee-up set value data Ty in the main memory 5.

Left side, right side, etc. can be set. The camera position setting value indicating the camera position is viewpoint position data. Therefore, viewpoint position data according 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.

In step S251, the button operation detecting means 1a determines whether or not the cross key has been pressed, and determines "YE

At step S259, the variable setting means 1h
Substitutes the minimum camera position setting value Camin for the camera position setting value Ca.

In the step S260, the variable setting means 1h
Sets the viewpoint position data Ex, Ey, Ez according to the camera position setting value Ca. As described above, the camera position setting value Ca is viewpoint position data. The viewpoint position data is registered in the table for each of the camera position setting values Ca. Therefore, “setting” here means that the variable setting unit 1h reads out the viewpoint position data corresponding to the camera position setting value Ca from the table.

In step S100, processing is performed according to an image display processing routine. This is a drawing process based on the viewpoint position data Ex, Ey, Ez set in step S260.

L. Control by the direction setting routine S300 (FIGS. 17 and 18)

FIGS. 17 and 18 show a direction setting routine S.
3 is a flowchart for explaining a control operation by 300. The direction setting value is angle data indicating the direction of the golfer's body in the golf game space, that is, the hitting direction. Therefore, the golf ball moves in the direction indicated by the angle data corresponding to the direction setting value in the golf game space. The direction setting value is incremented or decremented each time the right key R or the left key L of the cross key is pressed once. The unit of increment or decrement is the reference angle data Ang.

In step S301, the drawing command issuing means 1g issues a drawing command indicating drawing of a guidance image to the drawing processor 10. Thereby, the rendering processor 10 expands the guidance image data on the display area of the buffer 11. Thereby, the guidance image for setting the direction is displayed in the area Ar3 on the display surface of the television monitor 12 shown in FIG.
Guides Gu1 are displayed in the right area.

In step S302, the drawing command issuing means 1g issues a line drawing command corresponding to the initial value to the drawing processor 10. Drawing processing processor 10

If “NO”, the process moves to step S312.

At step S311, the variable setting means 1h
Substitutes “0” for the direction setting value Di.

In step S312, the drawing command issuing means 1g issues to the drawing processor 10 a drawing command for drawing a direction display image corresponding to the value of the direction setting value Di. Thus, the image on the area Ar3 shown in FIG. 5 is in a display state according to the value of the direction setting value Di.

In step S313, the drawing command issuing means 1g issues a line drawing command to the drawing processor 10. Thereby, the drawing processor 10

[0238] Control by hitting routine S500 (FIGS. 25 and 26)

FIGS. 25 and 26 show the impact routine S50.
6 is a flowchart for explaining a control operation by 0. Here, the term “hit” means that the game player operates the controller 22 so that the television monitor 1
2 means that a golf player Ma in the golf game space displayed on the display surface 2 hits a golf ball.
In this hitting routine, image display processing is performed until the golf ball hit by the golfer Ma in the golf game space falls and stops in the space.

In step S501, the drawing command issuing means 1g issues to the drawing processor 10 a drawing command indicating the drawing of the image of the hitting guide Gu3 shown in FIG. 3D. The drawing processor 10 writes the guide image data Gu3 shown in FIG. 3D into the display area of the buffer 11 based on the drawing command. As a result, FIG.
A guide Gu3 shown in D is displayed substantially at the center on the display surface of the television monitor 12.

Here, the guide Gu3 will be described.
When the game player operates the controller to cause the golf player Ma in the golf game space to make a hit, the guide Gu3 indicates the strength of the hit by his / her own operation (hereinafter, referred to as “the hit”).
This is an image for indicating to a game player how much energy is called “energy”). This guide Gu3
Has a shape in which a donut-shaped figure is partially cut out, as shown in FIG. 3D. The character "max" is attached to the upper part of the notch, and the character "min" is attached to the lower part of the notch. "Ma
“x” means that the power of the blow is maximum, and “mi”
"n" means that the power of the strike is minimal.

When the fourth button 22f is pressed while the guide Gu3 is displayed, the guide Gu is moved from the min position to the max position of the guide Gu3 during that time.
3 are sequentially filled. At this time, a predetermined amount of each color, such as yellow, light blue, blue, purple, and red, is painted. The tip of the filled part indicates the energy of the hit at that time. Therefore, the longer the time during which the fourth button 22f is pressed, the greater the energy of impact.

On the other hand, when the fourth button 22f is released in the above state, the painted portion of the guide Gu3 sequentially disappears from that point. In the case of the above example, from the position of max of the guide Gu3 toward the position of min,
The fill disappears in the order of red, purple, blue, light blue, and yellow. The tip of the filled part indicates the energy of the hit at that time. Therefore, the longer the time during which the fourth button 22f is released, the lower the energy of the impact. Once the fourth button 22f is released,
When the fourth button 22f is pressed again, the energy of the hit at that time is determined. When the energy of the impact is determined, the impact is performed. The corresponding part of the above explanation is
These are S501, S505 to S511 in the flowchart.

In the step S502, the random number generating means 1p

In step S503, the drawing command issuing means 1g sends a drawing command to draw character data and an arrow image according to the values indicating the wind direction WDi and the wind Wp.
It is supplied to the drawing processor 10. The drawing processor 10 writes image data indicating a wind force, a title, and an arrow in the display area of the buffer 11 based on the drawing command from the drawing command issuing unit 1g. Thereby, as shown in FIG. 5, on the display surface of the television monitor 12, an arrow By indicating a wind direction, a wind title ("WIND"), and a wind value (in this example, "4 m"). ")
Is displayed.

[0246] In step S504, the parameter management means 1o outputs the wind direction data WDi and the wind data Wp.
Is stored in the main memory 5.

In step S505, the button operation detecting means 1a determines whether or not the fourth button 22f has been pressed. If "YES", the flow proceeds to step S506.
If “NO”, the process returns to step S501.

In the step S506, the calculating means 1d sets
The reference value data k is added to the impact energy data POWER.

In step S507, the drawing command issuing means 1g sends a line drawing command corresponding to the value of the impact energy data POWER to the drawing processor 10.
Supply. Here, the line drawing command means that a line is drawn in a designated 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. The drawing processor 10 writes line data on the guide Gu3 written in the buffer 11 in accordance with the value of the impact energy data POWER based on the line drawing command. Thereby, the guide Gu3 displayed on the display surface of the television monitor 12
It is painted in a predetermined color.

In the step S508, the button operating means 1
a determines whether or not the fourth button 22f has been released,
If “YES”, the process shifts to step S509 and “N
If "O", the process returns to step S506.

In step S509, the calculating means 1d sets
The reference data k is subtracted from the impact energy data POWER.

In step S510, the drawing command issuing means 1g sends the drawing processor 10 a line drawing command corresponding to the value of the impact energy data POWER.
Supply. Based on the line drawing command, the drawing processor 10 writes line data on the guide Gu3 written in the buffer 11 by an amount indicated by 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 painted in a predetermined color. In the filling of the guide Gu3 in step S510, the value of the impact energy data POWER is reduced, so that the filled area on the display surface of the television monitor 12 is gradually reduced. Looks like it goes.

In step S511, the button operation detecting means 1a determines whether or not the fourth button 22f has been pressed. If "YES", the flow shifts to step S512.
If "NO", the process returns to step S509. Here, when the fourth button 22f is pressed, the impact energy data POWER at this time is determined.

In step S512, the calculating means 1d sets
"1" is added to the hit number data Hi. Then, the parameter management means 1 o stores the hit number data Hi in the main memory 5.

At step S513, the drawing command issuing means 1g sequentially supplies drawing commands indicating the drawing of the image of the golfer Ma to the drawing processor 10. The drawing processor 10 stores a buffer 11 based on the drawing command.
Are sequentially developed on the display area of. Thus, a series of animations is executed on the display surface of the television monitor 12 until the golfer Ma finishes hitting the golf ball.

In the step S514, the calculating means 1d sets
Ball position Bx, By, Bz, impact energy data P
OWER, tee-up data Ty, direction data Di,
Based on the stance data St, the club number data NO, the address data Had and Vad, the wind direction data WDi, and the wind data Wp, the ball positions Bx, B for each unit time
y and Bz are all determined. 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.

[0257] The time until the ball stops depends on the above parameters. Therefore, if the position of the ball for each frame is determined 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.

In step S515, the calculating means 1d sets
Add f to the variable n. Here, f means, for example, one frame.

In the step S516, the judgment means 1f sets
It is determined whether or not the variable n is larger than the maximum value nmax of n, and if “YES”, the process shifts to step S517,
If “NO”, the process moves to step S518. Here, nmax is the number of frames until the golf ball stops, as described above.

At step S517, the variable setting means 1h
Substitutes “0” for the variable n.

In step S518, the drawing command issuing means 1g supplies the drawing processor 10 with a drawing command indicating the drawing of the ball according to the ball position data Bxn, Byn, Bzn.

In step S519, the calculating means 1d sets
Add f to the variable n.

In step S520, the judgment means 1f sets
It is determined whether or not the variable n is larger than the maximum value nmax. If “YES”, the process exits from the striking routine S500. If “NO”, the process proceeds to step S521.

In the step S521, the variable setting means 1h
Substitutes the ball position data Bxn, Byn, Bzn for the viewpoint position data Ex, Ey, Ez.

At step S100, processing is performed according to an image display processing routine S100. The processing from step S519 to step S100 is processing for reproducing the flying state of the hit golf ball. The ball position changes every moment for each frame. Therefore, by substituting the ball position data Bxn, Byn, Bzn with the viewpoint position data Ex, Ey, Ez, the viewpoint also changes every moment. Since the viewpoint changes every moment, the background image also changes every moment. Thus, a so-called replay image is displayed on the display surface of the television monitor 12.

[0266]

According to the present invention described above, at least image information indicating the terrain at which the height of the apex is set is displayed on the display surface of the display means, and is within a predetermined range of the terrain image information. A line is displayed between any existing vertices, and the brightness of each line is set according to the relationship between the height of the top of the terrain information corresponding to the start point of each line and the height of the top of the terrain information corresponding to the end point. Since the distance / altitude expression method in the display space is characterized by the above feature, there is an effect that terrain information which cannot be represented only by terrain image information can be easily guided to the game player.
