Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional game machine which moves a virtual three-dimensional space by a predetermined moving body.

[0002]

2. Description of the Related Art FIGS. 30 (a) and 30 (b) show examples of game images in conventional shooting game devices and driving game devices.

For example, in the case of a shooting game device, as shown in FIG. 30A, the player operates the myship 530 while looking at the composite image of the myship 530, the enemy aircraft 532, etc. seen from above. I was playing a game. In the game device of such a system, the myship 530, the enemy aircraft 532, and the like can move only within the two-dimensional game field 536. Therefore, it was not possible to form a realistic game space full of realism.

Further, taking a driving game device as an example, as shown in FIG. 30B, the player two-dimensionally flows from the point A to the point B in the depth direction of the screen in the game field 538. A game was being played by operating the sports car 534 on the coming road. In such a type of game device, the sports car operated by the player can move only in the direction predetermined by the game device, that is, from the point B to the point A in FIG. As a result, the freedom of the operability of the player is limited, and the fun of the game cannot be enhanced.

[0005]

In order to solve the problem of the conventional game device, the inventor of the present invention can freely move around in a virtual three-dimensional space by a moving body operated by the player. We are developing equipment.
Here, the virtual three-dimensional space refers to a virtual three-dimensional space formed by the game program.

Now, in developing such a three-dimensional game device, the following technical problems arise.

First, when the moving body moves in the virtual three-dimensional space, a technical problem arises as to how the ground topography formed in the virtual three-dimensional space is reflected in the game. For example, when the moving body operated by the player is a land-based moving body, it is necessary for the player to experience uneven terrain such as hills provided in the virtual three-dimensional space. In this case, in the above-described conventional driving game device, the road and the sports car 534 are moved up and down in the direction of arrow C in FIG.
That is, since the conventional driving game device does not have the concept of a virtual three-dimensional space, it can be moved up and down only in the direction of arrow C, and the moving direction of the sports car 534 is from point B in FIG. Since it was limited to the direction of the point, it was possible to experience the uneven terrain to some extent just above and below the direction of arrow C. However, in a game device such as the present three-dimensional game device in which a moving body can freely move around in a virtual three-dimensional space, a player can be moved only by such a road and up and down in the direction of arrow C of the sports car 534. It is not enough to experience uneven terrain. Therefore, how to make the player experience such uneven terrain becomes a major technical issue.

[0008] Further, in the case where the game configuration is such that a moving body plays a battle game in the virtual three-dimensional space, how to reflect the terrain in the virtual three-dimensional space on the element of the battle of the battle game. There was also a technical problem. In other words, if there is uneven terrain, use this uneven terrain to protect against attacks from enemy tanks and helicopters, or conversely, make good use of this uneven terrain to avoid enemy tanks and With a game configuration that can attack a helicopter, the fun of the game can be significantly improved.

The present invention has been made in view of the above technical problems, and an object thereof is a three-dimensional game apparatus capable of reflecting the terrain formed in a virtual three-dimensional space in a game. To provide.

【Example】

1. Outline of Game First, an example of a three-dimensional game realized by the present three-dimensional game device will be briefly described.

According to the present three-dimensional game device, a virtual three-dimensional space is formed by a preset game program, and the formed virtual three-dimensional space can be freely moved around by the moving body operated by the player. Can provide space.

The three-dimensional game realized by the present three-dimensional game device is a future tank game spread in the near future city where various races are gathered. In this futuristic tank game, fighters who have gathered for huge prize money decide the champion in a death match game format in the game field surrounded by a square that cannot be escaped. Each fighter competes for a champion with its own future tank. The player then participates in the game as one of these fighters.

FIG. 2 shows an external view of the present three-dimensional game device. As shown in the figure, the player 302 operates the left and right analog levers 12 and 14 which are operation sections to perform CR.
The moving body imaged at T10, that is, the future tank 20 will be operated. That is, the player 302 can freely move back and forth, left and right in the game field 60 set in the virtual three-dimensional space by operating the future tank 20. Further, the analog levers 12 and 14 are provided with machine guns that can be fired indefinitely and missile triggers 16 and 18 that are powerful weapons with a limited number. Further, as shown in FIG. 2, the aim 40 is projected on the CRT 10, and the player 302 uses this aim 40 to attack the enemy. Further, the CRT 10 displays an enemy position detection radar 50 that detects the position of an enemy, which is a target, so that the player 302 can know the enemy position 52 with respect to the own-machine position 51.

An overall view of the game field 60 is shown in FIG. As shown in the figure, in the game field 60, various terrains formed in three dimensions and set by the game program are formed. That is, first
The four sides of the game field 60 are surrounded by walls 62 so that each fighter cannot escape. A first plateau 64 is provided on the inner circumference of the wall 62. The zero zone 66 is surrounded by the first plateau 64, and slopes 68, 70, 72, 74 are provided between them. Furthermore, in the zero zone 66, the second and third plateaus 76,
78 is also provided, and obstacles 80, 82 are also provided. As described above, the game field 60 in this three-dimensional game is the same as the conventional game field 60 shown in FIGS.
Unlike the game fields 536 and 538, which are composed of dimensions, they are composed of three-dimensional terrain. Therefore, it is possible to form a game space full of reality that has never existed before. Also,
On the other hand, in such a three-dimensional game device, how to make the player experience the three-dimensional topography becomes a major technical issue.

The future tank 20 operated by the player 302 and the enemy future tank 22 operated by the enemy fighter are facing each other on the zero zone 66. In FIG. 3, the future tank 2
The second and third plateaus 7 are located between 0 and the enemy future tank 22.
Since the players 6 and 78 are present, the player 302
The enemy future tank 22 cannot be seen by T10. Therefore, the player 302 first finds the enemy position 52 by the enemy position detecting radar 50 described above. Then, the future tank 20 is steered by the analog levers 12 and 14 to get over the second plateau 76, approach the enemy, and attack the enemy.

FIG. 4 shows a pseudo three-dimensional image displayed on the CRT 10 when the own future tank 20 approaches the enemy future tank 22 in this way. Here, the shield display section 54 displays the shield amounts of the own aircraft and the enemy future tank 22. At present, the shield amount (defense) of the player's own aircraft greatly exceeds the shield amount of the enemy future tank 22. Therefore, it is an opportunity for the player 302 to attack, and conversely, the enemy future tank 22 must avoid this critical situation and find an item that restores the shield amount.

In this case, the own future tank 20 is the zero zone 6
Located on top of No. 6, enemy future tank 22 is on the first plateau 6.
Since it is located at 4, there is a difference in height between the two.
Therefore, even in such a geographical condition, the player 302
However, it is necessary to set the game so that the enemy can be attacked well. On the contrary, if the enemy future tank 22 makes good use of this geographical condition and sets the game so as to avoid this critical situation, the interest of the game can be further enhanced. That is, how to reflect such a geographical condition in the game setting is a major technical problem in the present invention.

The above description is for the case where there is one player playing the game, as shown in FIG. When the player plays the game alone, the computer is in charge of the fighter who drives the enemy future tank 22. On the other hand, in FIG.
An external view of the present three-dimensional game device when two players play a match is shown. In this case, the player 302 uses C
While watching the RT10, pilot the future tank 20, and player 3
03 will operate the enemy future tank 22 while watching the CRT 11. Then, the CRT 10 displays a pseudo three-dimensional image viewed from the direction of the future tank 20.
In 1 is displayed a pseudo three-dimensional image seen from the direction of the enemy future tank 22. In this way, two players play a game under different geographical conditions while viewing pseudo three-dimensional images from different viewpoints in one virtual three-dimensional space. In addition, in FIG.
Although shown only for a human player, the present invention is not limited to this, and is naturally applicable to a case where a game is played by three or more players. 2. Description of Entire Device FIG. 1 shows a block diagram of an embodiment of a three-dimensional game device according to the present invention.

As shown in FIG. 1, the present three-dimensional game device has an operation unit 140 for a player to input an operation signal, a game space calculation unit 100 for setting a game space by a predetermined game program, and a pseudo at the player's viewpoint position. Three
An image combining unit 200 that forms a three-dimensional image, and this pseudo 3
It is configured to include a CRT 10 which outputs a three-dimensional image.

When the present three-dimensional game device is applied to a driving game, for example, a steering wheel, a gear or the like for driving a sports car is connected to the operation unit 140,
As a result, the operation signal is input. Also, when applied to shooting games such as the future tank battle,
Analog levers 12 and 14 for driving future tanks,
Also, triggers 16, 18 for firing a machine gun, missile, etc. are connected.

The game space calculation unit 100 is comprised of a central processing unit 1
02, object information storage unit 104, terrain information storage unit 106, and object information change unit 108. Here, the central processing unit 102 controls the entire three-dimensional game device. Further, a predetermined game program is stored in the storage unit provided in the central processing unit 102. In addition, the object information storage unit 104 stores object information that is position and direction information of a three-dimensional object that forms a virtual three-dimensional space, and other attribute information. In addition, the terrain information storage unit 10
6, the terrain information of the game field 60 formed by the above-mentioned three-dimensional terrain is stored as height data, for example. Further, the object information changing unit 108 performs a calculation to change the object information stored in the object information storage unit 104 based on the topographical information stored in the topographical information storage unit 106. The details of the configuration of the game space calculation unit 100 will be described later.

In the image synthesizing unit 200, a pseudo three-dimensional image seen from an arbitrary viewpoint position of the player 302 in the virtual three-dimensional space, that is, a pseudo three-dimensional image displayed on the CRT 10 in FIG. 2 is image-synthesized. Therefore, the image composition unit 200 is configured to include the three-dimensional image information storage unit 204 and the image calculation unit 202.

The three-dimensional image information storage unit 204 stores a three-dimensional image of a three-dimensional object. here,
The three-dimensional object is a moving body such as the future tank 20 or the enemy future tank 22 shown in FIG. 4, the wall 62 shown in FIG.
Second and third plateaus 64, 76, 78, obstacles 80, 82
It refers to all objects that form the game space set in the virtual three-dimensional space, such as topography. As shown in FIG. 4, this three-dimensional object is expressed as a set of polygons 90 to 95, etc., and information such as the coordinates of each vertex of this polygon is 3
It is stored in the three-dimensional image information storage unit 204 as three-dimensional image information.

The image calculation unit 202 includes an image supply unit 212 and an image forming unit 240.

The image supply unit 212 includes a processing unit 214 that controls the entire image synthesizing unit 200, a coordinate conversion unit 216 that performs a three-dimensional calculation process on image information such as the vertex coordinates of a polygon, and a clipping processing unit 218. The perspective conversion unit 220 and the sorting processing unit 222 are included.

In the image forming section 240, the image supply section 212
The image information of all the dots in the polygon is calculated from the image information such as the vertex coordinates of the polygon which has been subjected to the three-dimensional calculation processing in (3), and this is output as a pseudo three-dimensional image.

Next, the operation of the entire 3D game apparatus will be described.

First, at the same time as the game starts, the central processing unit 102 stores the object information, which is the position and direction information of all three-dimensional objects arranged in the virtual three-dimensional space, according to the game program, in the object information storage unit 104. To memorize. However, if a part of the object information storage unit 104 is a non-volatile memory and the initial value of the object information is stored in advance, such an operation is not necessary.

The object information stored in the object information storage unit 104 is stored in the format shown in FIG. 6, for example. In the figure, the index (0
N are serial numbers representing each three-dimensional object. For example, index 0 is a future tank 20, index 1 is an enemy future tank 22, index 2 is a wall 62.
The index 3 is a serial number representing a three-dimensional object forming the obstacle 80. This gives, for example,
The position information and the direction (tilt) information of the future tank 20 in the virtual three-dimensional space are (X0, Y0, Z0) and (θ0,
φ0, ρ0). As a result, the position and direction in which the future tank 20 is arranged are determined. Similarly, the position and direction information of the three-dimensional objects such as the enemy future tank 22 and the obstacle 80 are also set, whereby the position information of all the three-dimensional objects forming the game space in the virtual three-dimensional space, or the position information. Information and direction information will be determined.

In the case of a large three-dimensional object such as the future tank 20, this is divided into parts such as the cockpit, the left side driving part, the right side driving part, and the barrel, and each of these parts is divided into parts. May be considered as a three-dimensional object, and the index may be assigned to this. In this way, these parts, for example, the left drive unit, the right drive unit, the barrel, etc. can be independently moved, and the future tank 20 can be drawn with more realistic movement.

The terrain information storage unit 106 stores the terrain information of the game field 60 shown in FIG. 3 as height information, for example. The object information changing unit 108
By reading this topographical information, it is possible to change the position and direction information of the three-dimensional object stored in the object information storage unit 104. That is, for example, the position and direction information (X0,
The values of Y0, Z0, θ0, φ0, ρ0) are changed to change the inclination and the like of the future tank 20. This makes it possible to form a game space that reflects the terrain information. The details of the operation of the game space calculation unit 100 will be described later.

Next, the operation of the image synthesizing section 200 will be described.

First, the processing unit 214 reads the position and direction information of the three-dimensional object from the object information storage unit 104 using the index as an address. Similarly, the processing unit 214 reads the three-dimensional image information of the three-dimensional object from the three-dimensional image information storage unit 204 using the index as an address. For example, when the index is 0, the position and direction information of the future tank 20 (X0, Y0, Z0, θ0, φ)
0, ρ 0) is read from the object information storage unit 104, and the three-dimensional image information representing the future tank 20 as a set of polygons is read from the three-dimensional image information storage unit 204.

The processing unit 214 sequentially reads the indexes in this way and converts these information into a data format as shown in FIG.

FIG. 7A shows an overall view of this data format. As shown in the figure, the data to be processed is configured such that the frame data is at the head and the object data of all three-dimensional objects displayed in this frame are continuous. Then, after this object data, polygon data of polygons forming the three-dimensional object is further arranged.

Here, the frame data refers to data formed by parameters that change for each frame, and is common to all three-dimensional objects in one frame. The viewpoint position, viewpoint direction, and viewing angle of the player. It is composed of data such as information, monitor angle / size information, and light source information. These data are set for each frame. For example, when a window or the like is formed on the display screen, different frame data is set for each window. With this, for example, a rearview mirror,
It is possible to form a screen or the like of the future tank 20 viewed from above.

The object data refers to data formed by parameters that change for each three-dimensional object, and position information in units of three-dimensional objects,
It is composed of data such as direction information. This is data having almost the same content as the above-mentioned object information.

Further, the polygon data means data formed by image information of polygons and the like, and as shown in FIG. 7B, a header, vertex coordinates X0, Y0, Z0 to X3,
It is composed of other attached data such as Y3 and Z3.

The coordinate calculation section 216 reads out the data in the above format and performs various calculation processes on the coordinates of each vertex. The calculation process will be described below with reference to FIG.

Taking the future tank game as an example, FIG.
As shown in, three-dimensional objects 300, 332, and 334 representing future tanks, enemy future tanks, buildings, obstacles,
It is arranged in a virtual three-dimensional space represented by the world coordinate system (XW, YW, ZW). After that, the image information representing these three-dimensional objects is coordinate-converted into a viewpoint coordinate system (Xv, Yv, Zv) with the viewpoint of the player 302 as a reference.

Next, the clipping processing unit 218 performs image processing called so-called clipping processing. Here, the clipping processing is image information outside the field of view of the player 302 (or outside the field of view of the window opened in the three-dimensional space), that is, the front / rear / right / down / left / up clipping planes 340 and 342. 344, 3
This is image processing for removing image information outside an area (hereinafter referred to as display area 2) surrounded by 46, 348, and 350. That is, the image information required by the present apparatus for the subsequent processing is only the image information within the visual field of the player 302. Therefore, if the other information is removed in advance by the clipping process, the load of the subsequent process can be significantly reduced.

Next, in the perspective conversion unit 220, the display area 2
Only for objects inside is the screen coordinate system (XS,
YS) is perspectively converted, and the data is output to the sorting processing unit 222 at the next stage.

In the sorting processing section 222, the order of processing in the image forming section 240 in the next stage is determined, and the polygon image data is output according to the order.

In the image forming section 240, the image supply section 212
The image information of all the dots in the polygon is calculated from the data such as the vertex coordinates of the polygon which has been subjected to the three-dimensional calculation processing in (3). As a calculation method in this case, the contour line of the polygon is obtained from the vertex coordinates of the polygon, the contour point pair which is the intersection of this contour line and the scanning line is obtained, and the line formed by this contour point pair is given a predetermined color. You may use the method of making it correspond to data etc. In addition, the image information of all the dots in each polygon is stored in advance in a ROM or the like as texture information, and the texture coordinates given to each vertex of the polygon are used as an address, which is read and pasted. May be.

Finally, the pseudo three-dimensional image formed by the image forming section 340 is output from the CRT 10. 3. Description of Various Calculation Techniques in Game Space Calculation Unit Next, various calculation techniques performed in the game space calculation unit 100 will be described. (1) Reflection of Terrain Information on Object Information of Mobile Object The block diagram shown in FIG. 1 is a block diagram of an embodiment in which the topographical information is reflected on the object information of the mobile object, that is, the position and direction information of the mobile object. is there.

As described above, the object information changing unit 108 reads the terrain information from the terrain information storage unit 106, thereby changing the three-dimensional object information stored in the object information storage unit 104.

Here, the terrain information storage unit 106 stores terrain information of three-dimensional terrain as, for example, height information. The terrain information storage area of the terrain information storage unit 106 has a hierarchical structure as shown in FIG. That is, the game field area shown in FIG. 9A is the highest level, the lower level is the intra-district block area shown in FIG. 9B, and the lower level is the terrain block area shown in FIG. 9C. . Thus, the topographical information storage area has a hierarchical structure in order to compress the data amount and prepare a large number of game spaces in which more delicate topographical changes are reflected.

In the game field area, which of the plurality of game fields prepared in this three-dimensional game is to be selected is determined. As a result, for example, as shown in FIG. 9A, the game field 60 shown in FIG. 3 is selected.

This game field 60 is shown in FIG.
As shown in (a), it is divided into, for example, 4 × 4 = 16 intra-district blocks (17 to 32). 1 like this
By dividing one game field into a plurality of district blocks, that is, by combining, for example, 32 types of district blocks, an extremely large number of types of game fields can be easily formed. For example, by slightly changing the order of the intra-district blocks (pb17 to 32) shown in FIG. 10A, it is possible to easily form a game field having a completely different terrain from the game field 60 shown in FIG.

As shown in FIG. 10B, the block in this area is further divided into, for example, 4 × 4 = 16 terrain blocks. For example, the intra-district block pb17 is a topographic block pile000, 115, 118, 119,
It is divided into 16 terrain blocks of 122, which allows for further data compression.

The terrain block is a block in which the height information of the terrain is finally stored. FIG. 11 schematically shows the game field 60 formed by this terrain block. This FIG. 11 corresponds to FIG. 3 described above. Further, FIG. 12 shows the distribution of height information in each of these terrain blocks. In addition,
FIG. 12 shows the distribution of height information of the terrain blocks pile 115 to 123.

As shown in FIG. 11, since future tanks cannot enter the wall 62, no terrain block is arranged. In addition, the first plateau 64 in FIG.
It is represented by a combination of ile 115. In this terrain block pile115, as shown in FIG. 12, all the height information is set to 160. That is, it is expressed that the terrain is flat and located at a high position.

The slope 68 in FIG. 3 is represented by a combination of the terrain blocks pile 118, 121, 122, as shown in FIG. And terrain block pi
As shown in FIG. 12, le118 is highest on the left side (150) and lower on the right side (000),
Height information is set. As a result, the slope 68 can be expressed. Similarly, terrain block pile121
Has height information set so that a valley is formed at a corner.

For the zero zone 66, no terrain block is placed. This is because the zero zone 66 is a flat place with a height of zero, and it is not necessary to change the object information of the future tank. It is desirable that the zero zone 66 is set at a place where the future tank is located for the longest time during the game. With this setting, when the future tank is located at this location, the object information changing unit 108 does not need to change the object information and the data processing amount can be saved.

The obstacles 80 and 82 are set so that they can be destroyed by a missile fired by a future tank. When destroyed, a terrain block corresponding to the position is set at the position where the obstacles 80 and 82 were.

Now, the object information changing unit 108 changes the object information as follows.

First, the object information storage unit 104 refers to the index of the future tank 20, for example, index 0, and the object information (X0, Y0, Z0,
θ0, φ0, ρ0) are read.

Here, in the future tank 20, as shown in FIG. 13, virtual topographical information detection sensors 360, 362, 364 are previously arranged at four points A, B, C, D on the bottom surface thereof.
366 is provided. Then, first, the object information changing unit 108 determines the position information A (Xa0, Ya0, Za0), B (Xb0, Yb0, Zb) of these four points from the read object information (X0, Y0, Z0) of the future tank 20.
0), C (Xc0, Yc0, Zc0), D (Xd0, Yd0, Zd
0) is calculated.

Next, the object information changing unit 108
From the topographical information storage unit 106, A, B, C, and D obtained from the topographic information storage unit 106 are used as read addresses.
Topographic information at the positions of B, C, and D, for example, height information is read.

The topographical information storage unit 106 is read,
The read address need not necessarily be three-dimensional position information, and may be two-dimensional position information. For example,
The read address for the topographical information at point A is 2
Dimensional position information (Xa0, Ya0) is also sufficient. However,
For example, if there is a bridge on the game field,
The height information is set differently depending on whether the future tank 20 is located on the bridge or under the bridge. Therefore, in such a case, currently, the future tank 20 needs information for distinguishing whether it is located above the bridge or below the bridge, that is, the Z coordinate.

In the object information changing unit 108, the position information of the points A, B, C and D is changed as follows by the read height information dZa0, dZb0, dZc0, dZd0.

A (Xa0, Ya0, Za0) → A ′ (Xa0, Ya0, Za0 + dZa
0) B (Xb0, Yb0, Zb0) → B '(Xb0, Yb0, Zb0 + dZb
0) C (Xc0, Yc0, Zc0) → C '(Xc0, Yc0, Zc0 + dZc
0) D (Xd0, Yd0, Zd0) → D '(Xd0, Yd0, Zd0 + dZd
(0) From the changed points A ′ B ′ C ′ D ′, (Z0, φ0, ρ0) of the object information of the future tank 20 is as follows, as shown in FIG. 13 (b). Is changed to.

(X0, Y0, Z0, θ0, φ0, ρ0)
→ (X0, Y0, Z0 ', θ0, φ0', ρ0 ') As described above, the object information of the future tank 20 in the object information storage unit 104 is changed.

Next, if necessary, the object information of the enemy future tank 22, which is another moving body, is also changed.

FIG. 14 shows an example of a pseudo three-dimensional image when the object information is changed based on the topographical information as described above. As shown in the figure, the future tank 20 of the player's aircraft is located on the slope 75. Therefore, the present three-dimensional game device synthesizes a pseudo three-dimensional image in which the screen looks as if it is tilted as a whole, reflecting this topographical information. This state is clear if the image of the wall 62 is seen. Similarly, since the enemy future tank 22 is located on the second plateau 76, the enemy future tank 22 is seen above the own machine,
It is understood that the terrain information is reflected in the 3D game.

In the present embodiment, the case has been described in which the terrain information is reflected in the three-dimensional game to synthesize a pseudo three-dimensional image that looks obliquely inclined, for example. However, the present invention is not limited to this, and according to the configuration of the present invention, the terrain information is recorded in various patterns as described below.
It can be reflected in the dimension game.

For example, as the terrain information, terrain information that allows smooth movement and conversely, rugged terrain information such as a gravel road are prepared. Specifically, the height information of the terrain block is set more finely, and the terrain information of the rattling road is expressed by the terrain block in which the height information is finely changed. Then, conversely, the terrain information of the smooth road is represented by the terrain block having the same height information. As a result, for example, when the future tank 20 is moving on a rattling road, the pseudo three-dimensional image shakes finely, and when it is moving on a smooth road, the pseudo three-dimensional image does not shake at all. You will be able to experience the virtual movement of the road or the smooth road movement.

The terrain information reflected in the three-dimensional game is not limited to the height information as described above. For example, as the terrain information, terrain information such as a swamp, a wetland, and a desert is prepared, and the future tank 20 is placed in the swamp, the wetland, and the desert.
When is entered, the speed may be changed according to each terrain. This setting is specifically performed as follows.

As described above, the future tank 20 is steered by the operation signal from the analog levers 12 and 14 connected to the operation unit 140. For example, it is assumed that the player 302 pushes the analog levers 12 and 14 forward and the future tank 20 moves forward. Then, according to the operation amount, the object information stored in the object information storage unit 104 is displayed for one frame, that is, (1/60) seconds (hereinafter, T
Seconds) and then changed as follows.

(X0, Y0) → (X0 + VX0 × T, Y0 + VY0 × T) In order to simplify the explanation, the Z coordinate and the direction information θ,
We will not consider φ and ρ.

With respect to the object information changed in this way, the object information changing unit 1 operates as follows.
08 adds a negative value according to the topographical information.

(X0 + VX0 * T, Y0 + VY0 * T) .fwdarw. (X0 + VX0 * T-dX0, Y0 + VY0 * T-dY0) These added negative values -dX0 and -dY0 are stored in the terrain information storage unit 106. It is stored and read with the position information of the future tank 20 as an address. The added negative values -dX0 and -dY0 are set to different values depending on whether the terrain at that position is a smooth road, a swamp, a wetland or a desert. On the contrary, an ice road may be set, and when the road is on the road, a positive value may be added to accelerate the road. As described above, by using, for example, speed information as the terrain information reflected in the three-dimensional game, it is possible to greatly enhance the fun of the game.

Also, using velocity information as topographical information,
This and the above-mentioned virtual terrain information detection sensors 362-3
By combining 66, it is possible to further enhance the fun of the game. For example, a terrain block in which the speed information is set differently is prepared in the game field 60.
By doing so, the speed information is set to be different at each position of the four terrain information detection sensors 362 to 366 provided on the moving body.
It is possible to spin the moving body. As a result, the player can enjoy the pseudo three-dimensional image seen from the spinning moving body. As a result, it is possible to provide a game such as an ice driving game in which a player competes by spinning a moving body and watching a pseudo three-dimensional image of the spinning moving body from the viewpoint of the spinning moving body.

In this embodiment, the virtual topographical information detecting sensor is provided at four positions of the moving body, but the present invention is not limited to this, and the virtual topographical information detecting sensor is not limited to this. It may be provided at least at two positions of the moving body. For example, if only the inclination in one direction, that is, the inclination in the φ or ρ direction is reflected in the topographical information, it is sufficient to provide the topographical information detection sensors at at least two places. Further, if the inclination in two directions, that is, the inclinations in both φ and ρ are reflected in the terrain information, it is sufficient to provide the terrain information detection sensors at at least three places.
However, when the moving body is large, it is desirable to increase the number of topographical information detection sensors to be attached according to the size. (2) Reflection of terrain information on bullet movement position and hit determination Now, in the above-described embodiment, terrain information, for example, unevenness of terrain is reflected on a synthesized three-dimensional image to enhance the fun of the game. I was able to. On the other hand, when the 3D game represented by the 3D game device is a battle game such as a future tank game, not only the pseudo 3D image seen by the player but also the movement of the bullets fired by the moving body If this topographical information is reflected in the position or the hit determination, the interest of the game can be further enhanced. The bullets referred to here are not limited to machine guns, missiles and the like used in this three-dimensional game, but include all kinds of weapons such as light guns such as lasers, axes and arrows.

That is, by reflecting the terrain information on the movement position of the bullet or the hit determination, the interestingness of the game can be enhanced as follows. For example, when the future tank 20 of the aircraft is aiming at the enemy future tank 22, the unevenness of the terrain must be taken into consideration, and thus more complicated aiming work is required. On the contrary, when the enemy future tank 22 is attacked, it is possible to use the unevenness of the terrain, such as avoiding by making a height difference and making unevenness an obstacle. Also, if the moving body is tilted due to the uneven terrain, the "blind spot" can be complicated by the vertical movement of the line of sight and the shadow of the uneven terrain itself. In this way, the unevenness of the terrain makes “attack”, “avoidance”, “blind spots”, etc. more complicated, and it will be more interesting than ever in a battle game. This state is shown in FIG.

For example, in the case where the own future tank 20 attacks the enemy future tank 22, the following is performed. That is, FIG.
At 6, the aircraft is climbing up the slope and the barrel is facing up, so the bullet does not hit the enemy. Also, in, since the aircraft is on the same level flat land as the enemy, it is possible to catch the enemy in front. Also, in the downhill, the gun barrel is facing down and the bullet does not hit the enemy. Also, if you position yourself in a delicate location at the end of the uphill, you can catch the enemy in front. In addition, since the aircraft is climbing up a hill, the heights do not match and it is impossible to catch the enemy.

On the contrary, when the future tank 20 of the player's own machine avoids the attack from the enemy future tank 22, the enemy's bullet will not hit in any other place, so it should be avoided in the other place. . Thus, by reflecting the terrain information on the movement position of the bullet and the hit determination, it is possible to provide a more interesting game that is not available in the conventional two-dimensional game.

FIG. 15 shows a block diagram of an embodiment in which the above-mentioned topographical information is reflected in the movement position and hit judgment of the bullet.

The embodiment shown in FIG. 15 is different from the embodiment shown in FIG. 1 in that a bullet processing unit 120 and a trigger determination unit 142 are further included.

The trigger determination unit 142 determines whether or not the player has triggered the bullet, and thus a firing signal for the bullet is formed.

The bullet processing unit 120 has a structure including a bullet movement calculation unit 122 and a hit determination unit 126. The bullet movement calculation unit 122 calculates the movement position of the bullet from the object information of the moving body changed by the object information changing unit 108 and the firing signal of the bullet from the trigger determination unit 142.

In the hit determination unit 126, the object information of the target, for example, the enemy future tank 22 is read from the object information storage unit 104, and based on this object information and the movement position of the bullet calculated by the bullet movement calculation unit 122. The hit judgment is performed. When hit, the hit determination information is reflected in the object information of various three-dimensional objects stored in the object information storage unit 104.

Next, the operation of this embodiment will be described.

First, the object information changing unit 108 uses the terrain data stored in the terrain information storage unit 106 to change the object information of the moving body, that is, the future tank 20. For example, the future tank 20 is shown in FIG.
As shown in 7 (a) and 7 (b), when the vehicle is located on the slope 68, the height information and the tilt information of the future tank 20 are changed.

When the player operates the triggers 16 and 18 connected to the operation section 140 in this state, the trigger operation signal is input to the trigger determination section 142 via the operation section 140. Then, the trigger determination unit 142 determines whether or not the trigger of the machine gun or missile has been pulled, and when it is determined that the trigger has been pulled, a firing signal of the machine gun or missile is formed, and this firing signal is the bullet of the bullet processing unit 120. It is output to the movement calculation unit 122.

By the input of the firing signal, the bullet movement calculation unit 122 causes the object information storage unit 104 to change the object information (X0, Y0, Z0, θ0, φ0) of the changed moving body at the moment when the firing signal is input. , Ρ0) to read.

Next, the bullet movement calculator 122 determines that the firing position is (X0, Y0, Z0) and the firing direction is (θ0, φ0).
Then, the moving position of the bullet whose firing time is the time when the firing signal is input is calculated. In this case, the movement of the bullet obtained by calculating the movement position of the bullet is a linear movement in the direction, for example, assuming a future tank game in space. On the other hand, in a future tank game on the earth or the like, if gravity is taken into consideration, it becomes a parabolic movement. Then, if the parabolic movement is performed in this way, the future tank 20
It is possible to hit the bullets even if the barrel of the is not perfectly suitable for the enemy future tank 22. That is, as shown in FIG. 3, the first and second plateaus 76 and 78 are interposed between the future tank 20 and the enemy future tank 22, and even if the enemy cannot see the enemy tank from a long distance, for example, a long distance. It is possible to attack the enemy with the gun. As a result, the enemy can be attacked from a blind spot position that cannot be seen by the enemy due to the three-dimensional terrain, and the game can be made even more interesting.

In this future tank game, the axis line of the attack is set so as to substantially coincide with the front direction of the moving body. Therefore, the object information of the moving body is set to the initial position of the bullet firing position and the firing direction. The value can be used almost as is.
However, depending on the game, it may be set such that the moving body and the attack direction, that is, the direction of the barrel can be operated individually.
Then, in this case, the bullet movement calculation unit 122 determines the initial values of the firing position and the firing direction of the bullet based on the object information of the moving body and the operation signal of the barrel.

In the hit judging section 126, the bullet movement calculating section 12
At the position where the bullet calculated in 2 moves, the enemy future tank 22,
Alternatively, the object information storage unit 1 determines whether or not there is terrain information about the obstacle 80 or the second and third plateaus 76.
Check each object information of 04,
The hit determination signal according to the situation is output.

For example, when the enemy future tank 22 is located at the movement position of the bullet, the enemy future tank 2 is notified by this hit determination signal.
A three-dimensional object that represents hitting position 2
For example, a three-dimensional object of a pillar of fire is formed. Specifically, in the object information storage unit 104, new object information of a pillar of fire whose object information (X, Y, Z) is the same as the position of the enemy future tank 22 is newly formed. Also,
At the same time, the damage given to the enemy future tank 22 by this hit bullet is calculated. When it is determined that the enemy future tank 22 is destroyed by the calculation of this damage,
Processing such as deleting the object information of the enemy future tank 22 stored in the object information storage unit 104 is performed. If it is determined that the enemy future tank 22 has been deformed due to the damage of the bullet, although it was not destroyed, the enemy future tank 22
The index of the object information indicating the is changed to the index of the object information indicating the transformed enemy future tank. As a result, the image combining unit 200 can display the deformed enemy future tank.

Further, for example, when there is an obstacle 80 at the moving position of the bullet, the object information of the obstacle 80 in the object information storage unit 104 is erased. This makes it possible to destroy the obstacle 80 with a bullet. In this case, at the position where the obstacle 80 was, the terrain information that should be at that position is formed in the terrain information storage unit 106.

Further, for example, when there is a terrain such as a second plateau at the movement position of the bullet, the bullet becomes invalid and the object information of the bullet in the object information storage unit 104 is deleted.

After changing the object information as described above, the image synthesizing section 200 synthesizes a pseudo three-dimensional image according to the changed object information. 17 (a) and 17 (b) show an example of the pseudo three-dimensional image synthesized as described above. In the figure (a),
A pseudo three-dimensional image in which the machine gun 96 is fired upward is shown from the future tank 20 tilted upward.
Further, FIG. 3B shows a pseudo three-dimensional image in which the missile 98 is fired upward. This allows
It is understood that the topography information, that is, the inclination information of the slope 68 is reflected in the movement position of the bullet and the hit determination. (3) Bullet Tracking System Now, with the above-described embodiment, it becomes possible to reflect the terrain information on the movement position and hit judgment of the bullet. However, in the case of the game in which the three-dimensional topographical information is reflected in the moving position of the bullet in this way, the aiming work of the bullet becomes more difficult than in the past. For example, as described with reference to FIG. 16, the future tank 20 of its own machine can hit the enemy future tank 22 only in the case of or in FIG. Therefore, the enemy future tank 22 may easily escape. In this case, as described above,
If the parabolic movement is taken into consideration in consideration of gravity, the hit range will increase a little, but it is still difficult to hit if the enemy future tank 22 is located at a long distance. In this way, if the game configuration is such that the attacking player's bullets do not hit easily, the game will not progress and it will not be possible to provide a three-dimensional game full of speed. Therefore, in this embodiment, a bullet tracking system is newly provided,
This has solved the problem.

FIG. 18 shows a block diagram of an embodiment in which the tracking system is provided for the bullet as described above. FIG.
The embodiment shown in FIG. 15 has a configuration including a tracking movement calculation unit 124 newly in addition to the embodiment shown in FIG. The calculation of the tracking movement position of the bullet by the tracking movement calculation unit 124 is performed as follows.

First, the movement position of a bullet, for example, a missile, is input from the bullet movement calculation unit 122 to the tracking movement calculation unit 124. The moving position of the missile bullet is calculated as the moving position of the bullet reflecting the topographical information, as shown in the above-described embodiment.

The tracking movement calculation unit 124 performs a calculation for changing the movement position of the missile bullet based on the object information of the enemy future tank 22 stored in the object information storage unit 104. 19 and 20 show an example of the tracking movement position of the missile changed by the tracking movement calculation unit 124. In FIG. 19, when the missile hits by the tracking, the missile hits in FIG. 20. If not, it is indicated. The calculation of the tracking movement position will be described below with reference to FIGS. It should be noted that although a two-dimensional case will be described here for the sake of simplicity, this calculation is actually performed in three dimensions.

Now, let us say that the initial position of the missile 98 is M0 (X0
, Y0), the position of the enemy future tank 22 is set to En (XE
n, YEn). In addition, the calculation is performed for each frame (1/6
0 seconds) and the time of one frame is T.

First, the missile initial position M0 (X0, Y0) and the missile velocity V (V
X, VY) is input. As a result, if the change calculation is not performed in the tracking movement calculation unit 124, the movement position M1 (X1, X1) of the next missile is M1 (X1, X1) = M0 (X0, Y0) + V (VX , VY) * T = (X0 + VX * T, Y0 + VY * T) = (X0 + VX * T, Y0 + VY * T). Therefore, with such a calculation method,
In both cases of FIG. 19 and FIG. 20, the missile does not hit the enemy future tank 22.

On the other hand, in the tracking movement calculation unit 124,
First, from the object information storage unit 104, the enemy future tank 2
The initial position E0 (XE0, YE0) of No. 2 is read out, whereby the moving position M1 (X1, Y1) of the next missile is D0 (DX0, DY0) = E0 (XE0, YE0) -M0 (X0, Y0) M1 (X1, Y1) = M (X0, Y0) + V (VX, VY) .times.T + K.times.D0 (DX0, DY0). Therefore, X1 and Y1 are calculated as follows: X1 = X0 + VX * T + K * (XE0-X0) Y1 = Y0 + VY * T + K * (YE0-Y0). Here, K is a tracking constant, and the larger K is, the higher the tracking power of the missile can be.

Similarly, the next missile movement position M
2 (X2, Y2), M3 (X3, Y3), ------, Mn
(Xn, Yn) is calculated as follows.

X2 = X1 + VX * T + K * (XE1-X1) Y2 = Y1 + VY * T + K * (YE1-Y1) X3 = X2 + VX * T + K * (XE2-X2) Y3 = Y2 + VY * T + K * (Y2 + T + K2 (Y2 + T2) ) Xn = Xn-1 + VX * T + K * (XE (n-1) -X (n-1)) Yn = Yn-1 + VY * T + K * (YE (n-1) -Y (n-1)) In this way, the tracking movement calculation unit 124
When the enemy future tank 22 is finally positioned in the traveling direction of the missile 98 as a result of the change calculation by, the missile 98 hits the enemy future tank 22 as shown in FIG. On the contrary, if the enemy future tank 22 is not located in the traveling direction, the missile 9
8 will not hit the enemy future tank 22. Further, as can be seen from the above formula, if the enemy future tank 22 escapes faster than the tracking force of the missile, the enemy future tank 22 can escape from the missile attack. Therefore, by appropriately selecting the value of the tracking constant K in consideration of the speed of the enemy future tank 22 and the like, it is possible to adjust the hit range, thereby adjusting the difficulty level of the game. Becomes

The change calculation of missile tracking is not limited to the above formula, but various formulas can be used.
For example, using the angle θ between the advancing direction of the missile and the direction of the enemy future tank 22 shown in FIGS. 19 and 20, Xn = Xn−1 + VX × T + K × θXn-1 Yn = Yn-1 + VY × It can also be calculated as T + K × θYn−1.

After the calculation of changing the moving position of the bullet by the tracking system is performed as described above, the hit determining unit 126 performs the hit determining operation in the same manner as described above, and the image forming unit 200 performs the hit determining. The pseudo three-dimensional image corresponding to is combined.

The missile 98 is shown in FIGS.
Shows an example of a pseudo three-dimensional image until the player tracks the enemy future tank 22 and hits. The figure (a) is a state when the future tank 20 launches the missile 98. As shown in the figure, the future tank 20 of the player's aircraft is located on the slope 75. Therefore, the barrel of the future tank 20 does not face the enemy future tank 22. For this reason, if the missile 98 does not have a tracking system, the future tank 20 of its own cannot hit the enemy with the missile 98. FIGS. 7B and 7C show how the missile 98 follows the enemy future tank 22 after the launch. At this point, if the enemy future tank 22 escapes and the escape speed is high, the missile 98 cannot be tracked and the missile 98 does not hit. FIG. 3D shows a pseudo three-dimensional image when the missile 98 hits the enemy future tank 22 by tracking. In this case, as shown in FIG.
However, the mark of the hit on the position of the enemy future tank 22, that is, the pillar of fire 9
I'm ordering to give a 9.

As described above, according to the present embodiment, even in the case where the terrain information is reflected in the moving position and the hit judgment of the bullet in the three-dimensional terrain, the tracking system is used to detect the enemy. You can set the game so that you can easily attack. Then, in this case, by appropriately adjusting the tracking constant K according to the speed of the enemy and the like, it is possible to set the game of various difficulty levels, and realize a very flexible three-dimensional game device. You can do it. (4) Multi-player type game FIG. 22 shows an example of a block diagram in the case where the three-dimensional game device according to the present invention has a person-to-person multi-player type game configuration.

As shown in the figure, in this case, two or more operation units 140, the game space calculation unit 100, the object information storage unit 104, the image composition unit 200, and the CRT having the same configuration are prepared. Then, as shown in the figure, by sharing the object information stored in the object information storage unit 104, the present three-dimensional game device has the multi-player type game configuration shown in FIG. You can In this case, the common data is
At a minimum, the object data of mobile units should be shared. Further, in the case of a game configuration in which a missile, a machine gun or the like is used to attack, the object information regarding this bullet is also made common. The common method may be communication or the like, or the object information storage unit 104,
The board or the like on which the 104 is installed may be connected in common.

In the case of the multi-player type as described above, it is not necessary to make all the three-dimensional objects forming the virtual three-dimensional common, and for example, the virtual three-dimensional space that the player 302 and the player 303 can see. By making the composition slightly different, it is possible to configure a game space that is rich in variety.

Further, the configuration for making the three-dimensional game device a multiplayer game is not limited to that shown in FIG. For example, during (1/60) second which is one frame,
It is set so that there can exist a plurality of data groups including frame data shown in FIG. 7A, object data continuous with the frame data, and polygon data. By doing this, each frame data of a plurality of existing data groups
It is possible to set different viewpoint positions and viewpoint directions. By setting in this way, one game space computing unit 10 can be used within the range permitted by the speed of hardware.
0, the image composition unit 200 can form a plurality of pseudo three-dimensional images having different viewpoint positions and viewpoint directions. Then, by displaying the pseudo three-dimensional images viewed from different viewpoint positions and viewpoint directions on the CRT of each player, it is possible to eliminate the need for providing a plurality of image composition units and game space calculation units as shown in FIG. Also, a multi-player type three-dimensional game device can be realized. 4. Embodiment Using Head Mounted Body (1) Head Mounted Body The three-dimensional game device according to this embodiment may be configured such that a player wears a head mounted body to play a game.

The head mounted body is constructed by mounting a display device such as a liquid crystal display in front of the player's eyes so as to cover the player's visual field. Then, a device called a space sensor is attached to the head-mounted body to detect the three-dimensional information of the player. Then, by generating an image corresponding to the detection signal from the space sensor and displaying it on a display device, for example, an operation such as looking around, which is normally done casually, is performed in the virtual space in the same manner as the real space. You will be able to experience it with a sense of realism.

23A and 23B show an example of the shape of the head mounted body 609.

FIG. 23A shows a mounting body 609 in which a helmet space 612 is provided with a space sensor 612 for a player, an image display device 620, and a speaker 622. According to this type of wearing body, the player can wear the helmet 614 to create a world completely isolated from the outside, so that a more realistic virtual reality can be enjoyed. On the other hand, in the mounted body 609 shown in FIG. 23B, the space sensor 612 for the player, the image display device 620, the speaker 622, and the mounted band 61.
Since it is configured to be integrally attached to 6, it is possible to realize a more comfortable wearing feeling. The mounting body used in this embodiment is shown in FIGS.
It is possible to use various shapes other than the shape shown in FIG.

The image display device 620 is mounted in front of the player's eyes so as to cover the player's field of view, and displays the image information of the image information sent from the image synthesizing section 200 through the connection line 618. As an image display method in this case, it is desirable to use a small display such as a color liquid crystal display or a small cathode ray tube in order to downsize the head mounted body 609 and improve the wearing feeling.
Further, it is desirable to perform correction by an optical system so as to focus the eyes on the image and further widen the viewing angle to improve the realism.

Here, as the shape of the small display, it may be formed so as to cover the field of view of the player along the shape of the player's face so as to obtain a panoramic image effect. The shape may be formed in front of both eyes of the player. In the latter case, it is desirable to give a three-dimensional stereoscopic effect by giving an image with parallax to a two-dimensional two-dimensional image given to both eyes. With such a configuration, the size of the object and the distance to the object can be grasped, so that it is possible to create a virtual world that is closer to the real world.

The space sensor 612 is a sensor for detecting the three-dimensional information of the player, is attached to the player as shown in FIG. 23, and is connected to the image synthesizing section 200 side through the connection line 618 as shown in FIG. Has been done. The space sensor 612 is formed so as to detect the three-dimensional information of the player by a signal from a space sensor signal generator provided at a predetermined position.

The configuration is similar to that of the embodiment. Here, the coordinate extracting unit 682 extracts the player's viewpoint position and viewpoint direction from the detection signal input from the space sensor 612. Then, using the information on the viewpoint position and the viewpoint direction, a virtual field-of-view image at the viewpoint position and the viewpoint direction of the player is formed.

In this case, the method of forming the virtual view image is
The same method as the calculation method in FIG. 8 is used. That is, the processing unit 214 reads the object information from the game space computing unit 100 and the corresponding three-dimensional image information from the three-dimensional image information storage unit 204, and forms the data in the format shown in FIG. 7 from these information.

FIG. 5 shows a block diagram of an embodiment capable of such image composition. Further, FIG. 26A shows an external view of this three-dimensional game device.

In FIG. 26 (a), a future tank 630 made to look very similar to the real thing is installed on the floor 4 in the dome 1 whose inside is painted in blue. Here, the floor 4 is also painted in the same blue color as the inside of the dome 1. And this future tank 6
A player 650 is on board 30.

The future tank 630 has, for example, a cockpit 63
6, left side drive unit 632, right side drive unit 634, analog levers 640 and 641, instrument panel 644, and the like. Then, for example, the left drive unit 632 and the right drive unit 634 are the analog levers 640 and 64 of the player 650.
It is formed so as to be freely steered by the operation of 1. Then, as will be described later, the player 650 can see changes in these movements with the video camera 610.

The instrument panel 644 is, for example, a speedometer,
The player 6 includes a fuel gauge and a warning gauge (not shown).
It is configured to change depending on the operating state of 50.
That is, the analog levers 640 and 641 of the player 650.
The speedometer changes in response to the operation to, and when the game is over and the fuel runs out, the fuel gauge indicates this. Further, when a trouble occurs in the engine of the future tank 630, the warning indicator blinks, and the player 650
Can know this by the video camera 610.

At the bottom of the future tank 630, an attitude control unit 624 is provided, and the future tank 63 is responsive to the terrain information of the game field 60 and the operation signal of the player 650.

It is desirable to set so as to match the visual field direction of. This is because by setting in this way, the image of the real world that the player 650 can actually see can be seen more comfortably. As the image pickup means of the video camera 610, for example, a high resolution CCD or the like is used.

The dome is provided with the spatial sensor signal generator 13, and the spatial sensor 12 provided on the head of the player 650 can detect the three-dimensional information of the player.

Next, the image synthesizing method according to this embodiment will be described below.

In this embodiment, as shown in FIG. 26B, the real space image 700 in the real three-dimensional space photographed by the video camera 610 and the virtual view image 702 in the virtual three-dimensional space are image-synthesized. , A display image 704 is formed. Then, this display image 704 shows the connection line 618.

In other words, all but the future tank 630 and its accessories, the player 650 which is oneself, that is, the inside of the dome 1 and the floor 4 are colored in blue. By doing so, in the real space image 700, the future tank 630, the analog levers 640, 64
1, except for the player's hand 654, etc., has a blue background. Then, the display image 704 can be obtained by setting all the pixels of the blue color portion of the real space image 700 to empty dots and superposing them on the virtual view image 702. In this case, for example, the dome 1 shows a background mainly seen by the player 650, and the floor 4 shows the road surface situation of the game field 60 in which the future tank 630 is running.

A block diagram of an embodiment of the three-dimensional game device in this case is shown in FIG.

The display image synthesizing device 680 includes a field buffer 910 corresponding to each pixel of the display image. Then, the data control unit 908 refers to the empty dot determination data written in the empty dot memory 906, and writes the real space image at each pixel position of the field buffer 910. That is, when the pixel is determined to be an empty dot by the empty dot determination data, the real space video is not written at the pixel position of the field buffer 910. On the contrary, when it is determined by the empty dot determination data that the pixel is not an empty dot, 24-bit RGB digital data of the real space video is written as it is.

Next, the data control unit 908 refers to the empty dot determination data written in the empty dot memory 906, and the virtual field image information calculated by the image forming unit 240 is calculated at each pixel position of the field buffer 910. Is overwritten. That is, when the pixel is determined to be an empty dot by the empty dot determination data, the virtual field-of-view image information is written as it is. vice versa,
When it is determined by the empty dot determination data that the pixel is not an empty dot, nothing is written and the real space image is displayed at this pixel position.

After the above writing, the data control unit 908 reads out the image information data at each pixel position from the field buffer 910. Then, the image information data is sent to the image display device 620 through the connection line 618.
Image is output to the player 650 and the real space image 700 is displayed.
Thus, the display image 704 in which the virtual view image 702 is incorporated can be viewed in real time.

It is more preferable that the writing and reading of the image information described above are performed simultaneously, for example, by configuring the field buffer 710 for two screens.

Now, in the game space computing section 100, a voice signal output from the speaker 622 through the voice synthesizing section 678 and a posture control signal to the posture control section 624 are generated, whereby voice synthesis and posture control are performed. Be seen.

For example, the attitude control is performed as follows. First, the object information of the future tank is changed by the object information changing unit 108 using the terrain information of the terrain information storage unit 106. Then, the attitude control signal is generated using the changed object information, that is, the object information (X0, Y0, Z0, .theta.0, .phi.0, .rho.0) in which the terrain information is reflected. Then, this attitude control signal is output to the attitude control unit 624, whereby the attitude control is performed.

According to this embodiment having the above configuration, the player 6
Reference numeral 50 indicates the movement of the left-side drive unit 632, the right-side drive unit 634, and the like of the future tank 630 that is extremely close to the real thing, and the video camera 61
It is possible to freely maneuver the future tank 630 in the virtual three-dimensional space while actually checking through 0 through the eyes. As a result, operability is significantly improved, and a virtual reality world closer to reality can be expressed.
