It is known and is popular as a player who can experience a so-called virtual reality.

[0003] In such a three-dimensional game device, how to improve the sense of realism and presence of the player is a major technical problem. Taking a race game as an example, a car, a course, fixed objects arranged on both sides of the course are represented by three-dimensional objects, and a pseudo three-dimensional image is displayed on a display, so that it is visually recognized to some extent. Has succeeded in improving the sense of reality.

[0004] However, in order to allow a player to experience more realistic virtual reality, it is desirable to improve the sense of reality not only on the visual side but also on the auditory side. In the auditory aspect, for example, real engine sounds are played to the player, etc., but the presence of walls, etc., which are fixed objects placed on the left and right sides of the course, is not sufficient when producing game sounds. Was not considered at all.

The present invention has been made to solve the above technical problems, and an object of the present invention is to make it possible to make the presence of a fixed object in an object space audible. It is to provide a three-dimensional game device and an information storage medium.

[0006]

According to the present invention, there is provided a three-dimensional game apparatus for synthesizing a game sound with a visual field image at a given viewpoint in an object space.

Therefore, it is possible to make the player feel the presence of the fixed object arranged in the object space not only on the visual side but also on the auditory side, and it is possible to remarkably improve the real feeling and realism felt by the player.

Further, the present invention is characterized in that the reflected sound processing means increases the magnitude of the reflected sound as the distance between the moving body and the fixed object is shorter and the speed of the moving body is faster. I do.

In this way, the closer the moving body is to the fixed object, the more the loud reflected sound can be heard.
In addition, the higher the speed at that time, the more the reflected sound can be heard, so that the player can more effectively feel the presence of the fixed object.

Further, the invention is characterized in that the reflected sound processing means increases the height of the reflected sound as the speed of the moving body increases.

With this configuration, the higher the speed of the moving object, the higher the reflected sound can be heard, so that the player's sense of tension when approaching a fixed object can be further increased, and the fun of the game can be improved. Can be increased.

Further, the present invention is characterized in that the reflected sound processing means changes the localization of the reflected sound based on the direction information of the moving body and the positional relationship information between the moving body and the fixed object.

With this configuration, the player can feel the sense of position and sense of direction of the sound source of the reflected sound, so that the virtual reality felt by the player can be made more realistic.

Further, the present invention is characterized in that the moving body moves on a course provided in the object space, and the fixed object is arranged on at least one of both sides of the course.

This makes it possible for the player to visually recognize, for example, whether or not he or she has successfully passed the S-shaped curve of the course along a good line, and to show the player's enthusiasm for the game and the exhilaration felt by the player. It can be further improved.

Further, according to the present invention, the reflected sound processing means includes: course information including position information of each point set on the course, course direction information at each point, and course width information at each point; The reflected sound is changed based on the position information and the direction information of the moving body.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example of a functional block diagram of this embodiment. The operation unit 12 is used by the player to input operation information by operating a lever, a button or a handle, an accelerator, a brake, and the like. The operation information obtained by the operation unit 12 is output to the processing unit 100. Is done. Processing unit 10
0 performs various processes such as execution of a program, setting of various modes, arrangement of display objects, and the like based on the operation information and a given program and the like. It consists of. The image synthesizing unit 200 performs a process of synthesizing a view image (game image) at a given viewpoint in a three-dimensional object space in which a moving object, a fixed object, and the like are arranged based on the processing result of the processing unit 100. It is composed of, for example, an IC and a memory dedicated to image synthesis or a DSP and a memory in terms of hardware. The image generated by the image synthesizing unit 200 is output to the display unit 10 and displayed on the display unit 10. Sound synthesizer 3
Reference numeral 00 denotes processing for synthesizing a game sound based on the processing result of the processing unit 100, and is constituted by, for example, an IC and a memory dedicated to sound synthesis or a DSP and a memory in terms of hardware. The sound output unit 11 includes at least two or more speakers, for example, left and right speakers, and the game sound generated by the sound synthesis unit 300 is output to the player by the sound output unit 11. Is done.

The processing section 100 includes a reflected sound processing section 110. The function of the reflected sound processing unit 110 is realized by a given program, CPU, memory, and the like. In the present embodiment, the reflection sound processing unit 110 includes a moving object such as a car, a motorcycle, a tank, a robot, a ski (skier), a surf (surfer), a watercraft, and a spacecraft that move in the object space. The wall to be placed on the
Information on the distance between fixed objects such as mountains, islands, buildings, cliffs, rocks,
A process of changing a virtual reflected sound from a fixed object is performed based on at least one of the information on the speed of the moving object. At this time, the reflected sound processing unit 110 also changes the localization of the reflected sound based on the direction information of the moving body and the positional relationship information of the moving body and the fixed object.

The sound synthesis section 300 includes a sound processing section 302, a waveform storage section 304, and a volume adjustment section 306. The sound processing unit 302 performs various processes for sound synthesis. The waveform storage unit 304 stores digital sound waveform data that has been A / D converted and compression-encoded. Then, when there is a sound output instruction from the processing unit 100, the sound processing unit 302 reads out the sound waveform data designated by the processing unit 100 and performs a process of expanding (decoding) the sound waveform data. Then, if there is an instruction to increase the sound (instruction to change the pitch) from the processing unit 100, processing to increase the sound is also performed based on a given program. Then, the processed data is output to the volume adjustment unit 306. Volume adjustment unit 3
Reference numeral 06 includes, for example, a D / A converter, an amplifier circuit, and the like, and performs processing for adjusting the loudness of the sound based on the output from the sound processing unit 302. Then, based on the output from the volume adjustment unit 306, the sound output unit 11
It outputs game sounds such as GM.

The features of this embodiment are the distance between the car and the wall,
The point is that the sound reflected from the wall is changed based on the speed of the car. More specifically, as shown in FIG. 2, when the distance between the car and the wall is long, the reflected sound is made small and low, and when it is close, the reflected sound is made large and high. The higher the speed of the car, the higher the reflected sound. By doing so, the following effects can be obtained.

For example, as shown in FIG.
However, it is assumed that the vehicle travels on the S-shaped curve of the course 22.
In such a case, a line as shown in line 24,
In other words, it is ideal to pass through the left corner wall 26 and the right corner wall 28 slightly. FIG. 4 (A),
FIGS. 5B and 5A and 5B show examples of the field-of-view image synthesized by the image synthesizing unit 200 when the line is successfully traced as described above. FIGS. 4A and 4B are view images when the car approaches the wall 26 at the left corner.
(A) and (B) are view images when approaching the right corner wall 28.

As described above, if a course, a wall, and the like are constituted by three-dimensional objects and a pseudo three-dimensional image is synthesized,
The player can visually feel the sensation of traveling along the S-shaped curve along a good line. However, such a visual effect alone does not actually allow the player to enjoy a real sense of reality and a sense of reality.

Therefore, in this embodiment, the reflected sound is increased greatly as approaching the corner wall, and after the corner is cleared, the reflected sound is decreased as moving away from the corner wall. In this way, the case where the line is good as shown by the line 24 in FIG. 3 (A) and the case where the line is poor as shown by the line 25 in FIG.
The way of hearing the reflected sound can be made different, and the sense of realism and realism felt by the player can be greatly enhanced. That is, for example, suppose that the player tries to pass a very narrow line of the corner wall in an attempt to make a good line. Then, the player approaches the corner wall and feels nervous every moment.
(A), (B), images shown in FIGS. 5 (A), (B) can be visually perceived, and the reflected sound increases greatly as approaching the corner wall, so that it is audible. It is possible to feel, and the sense of realism and presence is greatly increased.

Further, in this embodiment, the reflected sound is greatly increased as the speed of the vehicle increases. That is, when the speed of the vehicle is high, it is more difficult to make a good line as shown by the line 24 in FIG. Therefore, if the reflected sound is made higher as the speed of the car increases, S
The player can be audibly recognized that the S-shaped curve has been cleared, and the satisfaction of the player for successfully clearing the S-shaped curve can be further increased. Conversely, when the S-shaped curve is cleared at a low speed, the unnaturalness felt by the player can be reduced by reducing the reflected sound to a low level.

According to this embodiment, even when passing through a normal curve, it is determined whether or not the player succeeds in a good line out-in-out as shown by the line 29 in FIG. 3B. Can be recognized audibly.

In the above description, both the magnitude and the height of the reflected sound are changed, but only one of them may be changed. Further, the reflected sound can be changed based on only one of the distance between the car and the wall and the speed of the car. From the viewpoints of realism, realism, and reduction of unnaturalness, the closer the distance between the car and the wall is, the larger the reflected sound is (and the height of the reflected sound is not changed). It is particularly desirable that the higher the speed, the higher the reflected sound.

Next, an example of the detailed operation of this embodiment will be described with reference to the flowchart of FIG.

First, in this embodiment, based on a given program, operation information from the player, and the like, for example, the position, direction, and speed information of the car are calculated for each frame (step S).
1). Then, the course information is read based on the obtained car position information (step S2).

Here, the course information includes position information of each point set on the course, direction information of the course at each point, width information of the course at each point, and the like. That is, as shown in FIGS. 7A and 7B, a plurality of points Pn are set on the course. Then, the course information including the position information Xn and Yn of the point Pn, the course direction information αn, and the course width information Wn is given to the game device in the form of table data as shown in FIG. It is stored in storage means. Here, Xn, Yn and αn are shown in FIG.
As shown in (A), the coordinates and angles are in an absolute (world) coordinate system. Further, the course width information on the left side and the course width information on the right side of the line 30 shown in FIG. 7B can be separately prepared.

In this embodiment, as shown in FIG.
A point Pn close to the car 20 is searched for based on the position information (X, Y) of. Then, the position information (Xn, Yn) and the course width information W included in the course information of the point Pn
n and the car 32, 3 based on the car position information (X, Y).
Then, the distance information (Wn-D) (actually D) with respect to No. 4 is calculated (step S3). Although FIG. 9 shows a case where only the course information of one point is used for simplifying the description, distance information or the like may be calculated using the course information of a plurality of points.

Next, based on the direction information of the vehicle calculated in step S1 of FIG. 6 (direction of the vector 36 in FIG. 9) and the direction information αn of the course included in the course information (the direction of the vector 38), An angle β between the direction of the car and the direction of the course is determined (step S4).

Next, the positional relationship between the car 20 and the walls 32 and 34 is determined (step S5). Here, as shown in FIG. 10, in the present embodiment, the course 22 is divided into a plurality of blocks along the course direction, and each block is assigned a block number. For example, in FIG. 10, the course 22 is divided into 800 blocks, and these blocks are respectively given block numbers B0 to B799. The block number is sequentially counted up each time a car passes through the block. Therefore, by searching for the block number of the block where the car is located based on the position information of the car, it is possible to easily know the current position, rank, and the like of the car on the course. For example, two cars are running on the course 22,
If the block number of the block where one car is located is B200 and that of the other car is B100, it is determined that one is currently the first place and the other is currently the second place. The points Pn on the course described in FIGS. 7A and 7B may be made to correspond one-to-one with the block numbers (in this case, the block numbers are included in the course information). For example, the interval between points Pn may be made smaller than the interval between block numbers.

In this embodiment, it is determined whether there is a wall on the left and right of the place where the car is located, using the above-mentioned block number. That is, in the present embodiment, as shown in FIG. 8B, table data in which a block number is associated with information indicating the presence or absence of left and right walls is stored in a given storage unit of the game device. . For example, in FIG. 8B, B0 to B2
In this block, there is a wall only on the left side, B250 to B252 have both left and right walls, and B345 to B347 have no walls on both the left and right sides.

Using the table data shown in FIG. 8B, the reflected sound processing unit 110 determines whether there is a wall on the left side of the car, a wall on the right side, or neither of the left and right walls. Further, based on the position information (X, Y) of the car, the position information (Xn, Yn) of the point Pn, etc., it is determined whether the car is located at the right, left or center of the course. to decide. Thus, the positional relationship between the car and the wall is determined in step S5 in FIG.

If it is determined that the car is on the left of the course and there is a wall on the left, the following equations (1), (2) and (3)
, The magnitude and height of the reflected sound are calculated (step S6).

L1 = K1 · V · D · (1 + COSβ) (1) Lr = K1 · V · D · (1−COSβ) (2) T = K2 · V (3) where Ll and Lr are respectively , Represents the magnitude of the left component and the right component of the sound reflected from the wall (hereinafter referred to as left sound and right sound), and T represents the height of the reflected sound. K1 and K2 are coefficients, and V represents the speed of the vehicle. Also, as shown in FIG. 9, D corresponds to the distance between the car and the wall, and β represents the angle between the direction of the car and the direction of the course.

In the above equation (3), the pitch T of the reflected sound is D
, But may depend on D.

On the other hand, if it is determined that the car is on the right side of the course and there is a wall on the right side, the magnitude of the reflected sound is calculated according to the following equations (4) and (5) and the above equation (3). The height is calculated (step S7).

L1 = K1 · V · D · (1−COSβ) (4) Lr = K1 · V · D · (1 + COSβ) (5) Also, the car is at the center of the course or there is a wall on the left and right If it is determined that there is no sound, the reflected sound is set to 0 (step S8).

In the above equations (1) to (5), the magnitude and height of the reflected sound have a relationship proportional to V and D. Formula (1)-
The magnitude and height of the reflected sound may be obtained by using the table data having the arguments Ll, Lr, and T obtained in (5) as arguments.

By calculating the magnitude and height of the reflected sound as described above, the reflected sound can be changed based on the distance between the car and the wall and the speed of the car, and the position of the sound source of the reflected sound can be changed. It is also possible to make the localization appropriate.

For example, consider the case where the car 20 is on the left of the course and the wall 32 is on the left. At this time, for example, FIG.
When the car 20 is oriented in the course direction as shown in (A) (when β = 0), as apparent from the above equations (1) and (2), the magnitude of the left sound is Ll. = 2 · K1 · V · D, and the loudness of the right sound becomes Lr = 0. That is, in the case of FIG. 11A, since the wall 32 is assumed to be present on the left ear side of the player, a large reflected sound is heard only from the left ear of the player (a large reflected sound is heard only from the left speaker). To do).

On the other hand, as shown in FIG.
When clockwise rotates, Ll gradually decreases and Lr increases slightly but slightly. And FIG.
As shown in (C), when the vehicle 20 rotates clockwise by 90 degrees with respect to the course, L1 = Lr = K1VD, and L1 and Lr become equal. That is, in the case of FIG. 11C, reflected sounds of the same magnitude can be heard by the left and right ears of the player.

When the vehicle 20 further rotates clockwise as shown in FIG. 11D, Ll further decreases and Lr further increases. In FIG. 11E, Ll = 0,
Lr = 2K1VD. That is, in this case, car 2
0 is in the opposite direction to the course direction, and the wall 32 exists on the right ear side of the player, so that the right sound volume Lr is maximized. Then, when the car 20 further rotates clockwise, as shown in FIGS. 11F, 11G, and 11H, Ll gradually increases and Lr gradually decreases.

As described above, according to the present embodiment, Ll and Lr change in accordance with the change in the direction of the vehicle 20. This allows the player to feel the localization of the sound source of the reflected sound,
It is possible to further increase the sense of realism and presence of the player.

FIGS. 12A to 12H show L when the car 20 is on the right side of the course and the wall 34 is on the right side.
Changes in l and Lr are shown. In this case, as shown in FIG. 12 (A), when the car 20 is facing the course, it is assumed that the wall 34 exists on the right ear side of the player. So that a loud reflected sound can be heard in the right ear of the player. On the other hand, FIG.
As shown in (E), when the car 20 is facing in the direction opposite to the course direction, it is assumed that the wall 34 exists on the left ear side of the player. Make the ears hear loud reflections.
