Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an image processing apparatus, an image processing method, and a game apparatus for moving a moving body composed of polygons or the like on three-dimensional space coordinates and generating a viewpoint image when the moving body is viewed from a predetermined viewpoint. is there. Further, the present invention relates to a game device that includes a plurality of game devices and is used for attractions and the like.
[0002]
[Prior art]
With the recent development of computer graphics technology, data processing devices such as game devices and simulation devices have become widespread. Some game devices operate, for example, a character or a vehicle on a screen by operating a joystick (operating rod) or a button. In recent years, a three-dimensional shape is composed of a plurality of polygons, and textures (patterns) are mapped to the polygons so that characters can be displayed from any viewpoint. . As an example of this, drawing is performed with polygon data with texture mapping applied to a three-dimensional character, and the background portion that requires movement in accordance with the character's motion and change of viewpoint is also drawn with textured polygon data. TV game devices are known.
[0003]
Furthermore, a TV game apparatus is known in which a player operates a vehicle on a screen at a seat resembling a vehicle of the game and feeds back the state of the vehicle on the screen to the vehicle to further enhance the feeling.
[0004]
[Problems to be solved by the invention]
By the way, most of the conventional game devices have a single player, and few players (for example, a couple) enjoy the same ride on the same vehicle. In particular, none of the plurality of players enjoys a game such as a time trial on the same vehicle while simultaneously operating the same object (vehicle) in the three-dimensional space.
[0005]
In addition, many conventional game devices run on a course determined by a vehicle, but there are many relatively monotonous ones that go around the same course. If you configure the screen to run in various environments using 3D representation, it will be more interesting, but it is very difficult to display a completely different background at a certain point due to the limit of the processing power of the processor It is. If such a process is forcibly performed, the real-time property may be impaired, which may cause unnaturalness.
[0006]
Further, when the vehicle moves in the three-dimensional space, the vehicle may sink into the ground depending on the operation of the player. This hardly occurs when the vehicle runs only on a conventional flat terrain (road), but often occurs when the vehicle passes a track with a bank utilizing a three-dimensional space. The runway with a bank is more powerful and realistic in terms of game progression. It is necessary to correct the future position of the vehicle to an appropriate position. At that time, it is also necessary to make the vehicle move more realistically.
[0007]
Further, when the vehicle moves in the three-dimensional space, the vehicle tilts. It is desirable to accurately reflect this tilt on the player's vehicle. However, the mechanical inclination of the vehicle often cannot follow the state of the vehicle in the three-dimensional space processed in real time by the processor. This is even more so on a runway with a bank. This will impair the actual feeling of the game.
[0008]
In short, in reality, in a game configured in a three-dimensional space, the actual feeling may be impaired.
[0009]
The present invention has been made to solve the above problems, and an object of the present invention is to provide an image processing apparatus and an image processing method in which a plurality of players can simultaneously operate the same object in a three-dimensional space.
[0010]
Another object of the present invention is to provide an image processing apparatus and an image processing method capable of rewriting the background naturally without imposing a heavy burden on the processor.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below. First, a game device (power thread (TM)) in which the player sits on a vehicle-type seat and plays in the embodiment which is an example of the present invention will be described, and then a play facility using a plurality of the game devices will be described. To do.
[0040]
1. Game device
1.1 Outline
This game device provides a game in which a player operates a vehicle (ride) virtually created by a computer and runs through a predetermined course. Like a traditional car racing game, you can compete for time and enjoy a chase with other rides. However, this game apparatus differs from the conventional car racing game in several points.
[0041]
First, the vehicle of this game is not a car, a motorcycle, etc., but an image of a bobsled which is also a winter Olympic competition. Bobsleigh is a game that is very speedy because it runs through the ice course at a very high speed and the course itself is narrow. This game is also a game full of speed.
[0042]
Second, all courses have banks and the vehicle tilts greatly depending on which part of the course is run. In conventional racing games, there were almost no banks. This makes the game more thrilling and more enjoyable for the player. In this regard, contrivances have been made for both the vehicle mechanism and image processing.
[0043]
Third, this vehicle is a two-seater and is operated based on the operations of a plurality of players. In addition, the player does not operate with buttons, but sits on a seat resembling a vehicle on the screen and operates with an operation lever provided on the vehicle. Coupled with the fact that the vehicle shakes or tilts according to the situation on the screen, a more realistic experience is possible.
[0044]
1 is a functional block diagram of a game apparatus according to Embodiment 1 of the present invention. FIG. 1 includes three blocks (a processing unit 1, a vehicle (ride) 2, and a display unit 3). These blocks form one ride. The appearance of the ride 2 and the display unit 3 will be described later, and the function will be described here.
[0045]
The processing unit 1 performs processing such as generating a game screen to be displayed on the display device, advancing the game based on the operation of the rider 2 and tilting the ride 2 according to the game situation. The B-CRX 11 is a video output board provided with a graphic processor, which generates a game screen and sound effects and controls rides in the screen based on player operations. Ride angle data generated by the B-CRX 11 is once sent to the AXIS BD 14 through a main control system (not shown). It is also displayed on an attendant monitor (not shown). A main control system (not shown) sends commands (start, game end, emergency stop, etc.) to the game board (B-CRX11). The AMP 12 receives the sound effect from the B-CRX 11, amplifies it, and sends it to the SPEAKER 27 of the ride.
[0046]
The vibration exciter 13 receives a control signal from the B-CRX 11, and generates a drive signal for vibrating the ride 2 seat as the game progresses. For example, during a ride, there is no vibration on a smooth road and vibration is applied on a rough road. The AXIS BD 14 receives the angle signal generated by the B-CRX, generates a drive signal for tilting the ride 2 according to the progress of the game, and sends this to the SERVO DRIVER 15. Based on this drive signal, the SERVO DRIVER 15 drives the SERVO MOTOR 21 that rotates the ride 2. For example, while a ride is in progress, it does not tilt at the center of the road where the bank is located, but tilts at the end. The tilt of the ride reflects the tilt of the ride in the game as well as the tilt of the screen. Details will be described later. SEQUENCE UNIT 16 is a safety-related relay sequence for controlling the entire apparatus. SW REGU 17 is a switching regulator power supply. B-CRX11, AXIS BD14, and SEQUENCE UNIT16 are also connected to an operation panel of an attendant staff (not shown).
[0047]
Ride 2 is a vehicle in which two players get on and operate the provided operating lever to enjoy the game. The SERVO MOTOR 21 is driven by a drive signal from the SERVO DRIVER 15 and tilts the ride 2. POSITION SENSOR 22 detects the slope of ride 2 and sends this detection signal to AXIS BD14. LIMIT SWITCH 23 is a switch that is attached to the rotation shaft of the ride and stops the ride when the ride 2 moves beyond a preset angle. The LIMIT SWITCH 23 is attached to the axis of the ride, and is composed of a disk in which a part thereof is cut out and two photo sensors for detecting the cut out part. Or you may comprise by a microswitch. The ON / OFF signal of the LIMIT SWITCH 23 is supplied to the AXIS BD 14 and the SEQUENCE UNIT 16.
[0048]
The ANALOG 24 is a volume attached to the operation lever, and two volumes are provided on each of the two seats of the ride 2. When the player operates the operation lever, the resistance value of the ANALOG 24 changes according to the operation amount. BUTTON 25 is an entry button and a call button provided at the front and rear seats of the ride 2, respectively. The entry button is for confirming whether there is a customer and whether the customer is ready. The call button is for informing the attendant when the customer feels bad during the game. The BUTTON 25 on / off signal is supplied to the B-CRX 11. Two SPEAKERs 26 are provided in front of the front seat of Ride 2 and two behind the rear seat to generate sound effects. The vibration MOTOR 27 includes a cam that taps under the seat. The vibration MOTOR 27 is attached under each seat. The seat surface of the seat swings up and down by the vibration MOTOR 27. By controlling the rotation of the motor, it is possible to easily control the speed. The vertical movement at this time is about 5 cm.
[0049]
The display unit 3 is provided in front of the ride and displays a game screen and generates sound effects. The SCAN CONVERTOR 31 scan-converts the game screen signal generated by the B-CRX 11 and supplies it to the LCD PROJECTOR 32. The LCD PROJECTOR 32 is a projection type large screen television using liquid crystal. The SPEAKER 33 is a BGM speaker provided on the upper part of the LCD PROJECTOR 32. The illumination device 34 illuminates a ride or the like. The CAMERA 35 is provided on the upper part of the LCD PROJECTOR 32 and photographs the ride 2 customer.
[0050]
The MAT SWICHT 4 is provided on the floor on both sides of the ride 2. The ON / OFF signal of MAT SWITCH4 is input to SEQUENCE UNIT 16, and if the mat switch is turned on while ride 2 is in operation, ride 2 will stop emergency. Invalid when ride 2 is stopped.
[0051]
Next, an outline of the operation will be described based on the flowchart of FIG.
[0052]
At the direction of the attendant staff, two customers will get on the ride and prepare to tighten the safety belt. When the attendant confirms that the preparation is complete, the game starts. The image processing board B-CRX 11 generates an image based on information stored in advance, and displays a game image on the LCD projector 32. While watching this game screen, the customer operates the operation lever to enjoy the game.
[0053]
ST1: Input from the operation system (lever) to the image CPUBD (B-CRX)
When the customer operates the operation lever, the analog input means 24 (volume or the like linked to the operation lever) outputs a signal corresponding to the operation. This signal is input to the B-CRX 11.
[0054]
ST2: Calculate the ride angle with the image CPUBD
The B-CRX 11 controls the ride on the screen by moving it forward, backward, left and right based on the operation input, and calculates the angle according to the position of the ride. The ride path is a semi-cylindrical bank course that tilts to the right if the ride is on the left and to the left if the ride is on the left. Also, the slope changes depending on the direction of the ride. The B-CRX 11 calculates the tilt angle of the ride in real time while taking these into consideration.
[0055]
ST3: Transfer the angle to Ride Control BD (AXIS BD14)
The ride inclination angle obtained in step ST2 is transferred to the ride control BD.
[0056]
ST4: Drive servo motor with ride control BD
Based on the input angle data, the ride control BD generates a drive signal and outputs it to the servo driver 15. Based on this drive signal, the servo driver 15 drives the servo motor 21. The servo motor 21 rotates the ride 2. A specific mechanism will be described later.
[0057]
ST5: Ride actually moves
The ride rotates as the servomotor 21 rotates.
[0058]
ST6: The value of the position sensor of the ride is fed back to the image CPUBD, and the angle of the ride by the position sensor 22 provided on the rotation axis of the feedback ride 2 is fed back to the image CPUBD (B-CRX11).
[0059]
ST7: Correct the angle of the image to match the actual angle of the ride
The B-CRX 11 compares the inclination angle of the ride on the game screen with the actual angle at which the ride 2 is inclined by the servo motor 21. When they match (or when they are within a predetermined allowable range), no particular processing is performed on the image side. On the other hand, when the two do not match, a process of tilting the image is performed. This discrepancy is that the mechanical rotation of the ride takes time and does not always match the tilt on the game screen. It is caused by giving pleasure. Therefore, when there is a mismatch, the game screen is tilted according to the mismatch amount. Customers don't feel unnatural if the ride is lean, but the screen tilts accordingly. In short, it is only necessary that the relative relationship between the screen and the ride matches the inclination in the game screen. This process is performed particularly when (actual angle) <(angle in the game screen). Specific processing will be described later.
[0060]
ST8: Image output
The B-CRX 11 outputs an image with the angle corrected.
[0061]
1.2 Mechanism part
FIG. 3 is a top view of the ride. 4 is a cross-sectional view taken along line AA in FIG. 5 is a cross-sectional view taken along the line BB in FIG. FIG. 6 is a detailed view of the drive unit. In these figures, the display of the vibration motor 28 is omitted.
[0062]
In FIG. 3, 50 is a frame, 51 is a main body of the ride, 51a is provided on the main body of the ride, and is a convex portion for rotating the ride, 52a and 52b are seats, and 53a and 53b are operation levers. One operation lever 53a is provided on each of the left and right sides of the seat 52a, and one operation lever 53b is provided on each of the left and right sides of the seat 52b. Reference numerals 54 and 55 denote rotary bearings. The ride can rotate around the rotation shafts 54 and 55.
[0063]
In FIG. 4, 56 is a drive unit, and 57 is a rotation unit rotated by the drive unit. The rotating portion 57 is in contact with the convex portion 51a, and the main body 51 of the ride rotates about the rotation shafts 54 and 55 with the rotation. In the figure, a state rotated about 45 degrees to the left and right is indicated by a dotted line. The specific rotation method depends on the control of the processing unit. Details will be described later.
[0064]
In FIG. 5, the rear seat 52b is provided at a position higher than the front seat 52a. This is in order not to obstruct the view of the passengers behind. The drive unit 56 includes a motor 56a and a gear unit 56b. The gear part 56 b is connected to the rotating part 57. In this figure, it turns out that the rotation part 57 is double and these are contacting the convex part 51a.
[0065]
FIG. 6 is a detailed view of the driving unit 56 and the rotating unit 57 as viewed from above.
[0066]
1.2.1 Rolling mechanism
As described above, the main body 51 of the ride rotates around the rotation shafts 54 and 55. Therefore, it is possible to roll the entire ride. The main body 51 of the ride rolls to the left and right to draw an arc as shown in FIG. The position of this shaking is detected by a rotation detector such as a potentiometer, a rotary encoder, and a synchro transmitter provided on the rotating shaft 54. This position can be linearly controlled. The size of the arc is about 2.5 to 3 m in diameter, and the rotation angle is about 180 degrees at the maximum, but actually it is much smaller. This rotation angle can be controlled from the board.
[0067]
By the way, the two players on the ride operate the operating lever 53 while looking at the screen of the traveling path generated by the computer, and run through. Since the bank is attached to the road, the ride tilts depending on the position where the ride runs, and the ride also tilts depending on the running state. By tilting the ride body 51 on which the player rides based on this tilt, the player can enjoy a more realistic game.
[0068]
Next, specific motion ride control will be described.
[0069]
The motion data (rotation angle) is created as follows.
[0070]
The motion data is obtained based on the player's operation and the actual running situation. That is, from the handle information (handle cut angle) when the player operates the operation lever 53 and the information (roll: Z rotation angle) from the road surface on the screen at that time, every interrupt (for example, 60 minutes) at regular intervals. Create target motion data (rotation angle) every 1 second) and move the motion.
[0071]
At this time, the motion data is obtained by taking a weighted average of the two data of the operation data and the road surface data. For example, when the course is flat, the motion ride does not rotate much because the road roll is small. Therefore, motion data is created so as to place a weight on the corner of the handle. Conversely, when the road surface is banking, the roll is large and the motion ride tilts due to the influence of the road surface. Therefore, the motion data is created such that the roll is weighted more than the handle angle. This can be expressed as follows.
[0072]
Target rotation angle of motion =
(M × handle angle + n × Z rotation angle) / (m + n)
Here, m and n are weighting factors. When the course is flat, m is large and n is small. When there is a bank on the course, m is small and n is large.
[0073]
By the way, in consideration of the player, the rotation angle of the ride is limited within a certain range. Even if the ride is greatly inclined on the screen, the actual inclination of the ride body 51 is within the limit and is not so large. In addition, a physical time lag occurs between the actual ride angle and the target rotational position. Insufficient tilt is achieved by tilting the screen display. That is, the motion is rotated to the target rotation angle. At this time, the rotation angle is calculated for each interrupt in consideration of the current angle of the motion. For example, assume that the target rotational position P1, the position P2 at the next interrupt, and the current position P3 are as shown in FIG. The inclination of the current position P3 is relatively small, and the inclination of the position P2 at the next interrupt can be made relatively large. The difference θ between the slope of P2 and the slope of P3 is relatively large. The motion main body 51 is rotated based on this θ. On the other hand, assume that the target rotational position P1, the position P2 at the next interrupt, and the current position P3 are as shown in FIG. The inclination of the current position P3 is relatively large, and the inclination of the position P2 at the next interrupt is limited. The difference θ between the slope of P2 and the slope of P3 is relatively small. In such a case, the target rotational position P1 is achieved by the inclination of the screen display rather than the inclination of the ride body 51.
[0074]
As described above, the ride angle is calculated and moved, and when the actual ride angle cannot be followed due to a physical time lag, the actual rotation angle of the ride is obtained by the ride position sensor. This is fed back, and the image is corrected and drawn.
[0075]
1.2.2 Operating mechanism
The operation system includes four operation levers 53a and 53b. As can be seen from FIGS. 3 to 5, there are two operation levers in the front and rear seats. Each of these control levers has a control bar (not shown). FIG. 7 schematically shows the state of these operation levers.
[0076]
The ride in FIG. 3 is a two-seater, and each passenger can operate the ride. The four control bars are linked and connected to the 1ch volume. As a result, the operations of each person are collected and transmitted to the processing unit. The process of this part will be described later.
[0077]
The operation of the operation lever will be described with reference to FIGS. When the ride is rotated to the right, as shown on the left side of FIG. 8, the left operation lever 53-L is tilted forward and the right operation lever 53-R is tilted backward. When rotating leftward, as shown on the right side of FIG. 8, the left operating lever 53-L is tilted backward and the right operating lever 53-R is tilted forward. Also, when accelerating the ride, both control levers are tilted forward, and when the ride is decelerated, both control levers are tilted back. As described above, the left and right can be controlled separately by the operation lever.
[0078]
1.3 Computer graphics part
The processing by the computer will be described individually.
[0079]
1.3.1 Method for determining the positional relationship between a polygon (polygon) and a point
In the method of determining the positional relationship between a polygon (polygon) and a point, normally, as shown on the left side of FIG. 12, a vector V1 connecting the vertex of the polygon and the point P (x, y, z), the vertex of the polygon, and the next vertex The positional relationship is determined by determining the outer product formed by the vector V2 connecting the vectors V2 and examining the direction of the vector V3 and the normal vector n of the polygon.
[0080]
In the embodiment of the present invention, the determination is made by substituting the point P (x, y, z) into the equation ax + by + cz + d of the polygon plane and looking at the sign. If ax + by + cz + d = 0, it is above the polygon, if ax + by + cz + d <0, it is below the polygon, and if ax + by + cz + d> 0, it is above the polygon.
[0081]
1.3.2 Course collision, road surface (polygon) selection method
In the embodiment of the present invention, the traveling path formed by the computer is a half pipe (semi-cylindrical) course as shown in FIG. In this embodiment, basically all courses have banks. FIG. 13 also shows the coordinate system in the course.
[0082]
Each course is configured as shown in FIG. FIG. 14 shows a top view and a cross-sectional view of the course. The coordinate system in the course is also shown. In the figure, S is a sector. Sector S is one polygon (triangle or quadrangle) that forms the ground. In the illustrated example, there are five sectors. B is a block. Block B is a set of horizontal rows of sectors. In the example shown in the figure, five sectors gather to form one block. A is an area. Area A is a set of several blocks B. In the example shown in the figure, two blocks B gather to form one area.
[0083]
In this embodiment of the present invention, a large number of areas shown in FIGS. 13 and 14 are connected to form a course on which a ride runs.
[0084]
For example, the ride is composed of a plurality of polygons as shown in FIG. This ride is a three-wheeler with two front wheels and one rear wheel. Therefore, when this ride is used, three-point collision determination may be performed. It goes without saying that the ride may be two wheels, four wheels or the like.
[0085]
Next, the course collision and the road surface (polygon) selection method will be described.
[0086]
First, a method for identifying a block where the user (ride) is present will be described. In FIG. 16, a point P (x, y, z) is a position where the user is present. The plane on the left side of the block where the user is present is JBL1: a1x + b1y + c1z + d1 = 0, and the plane on the right side of the same block is JBL2: a2x + b2y + c2z + d2 = 0. It is assumed that the normal line n1 (a, b, c) of the plane JBL1 and the normal line n2 (a, b, c) of the plane JBL2 are both oriented in the course direction.
[0087]
In the above case, as described above, the following relationship is established between the equations of the planes JBL1 and JBL2 and the point P (x, y, z).
[0088]
a1x + b1y + c1z + d1> 0
And
a2x + b2y + c2Z + d2 <0
As described above, when the coordinate where the user is located is P (x, y, z), and there is a relationship as described above with the planes on both sides of a certain block, the self (ride) is positioned within the block. Can be judged. Therefore, in order to specify the block in which the user is present, the above-described determination may be performed for each block. If it is not your block, the relationship is as follows.
[0089]
a1x + b1y + c1z + d1 <0
And
a2x + b2y + c2Z + d2 <0
Or
a1x + b1y + c1z + d1> 0
And
a2x + b2y + c2Z + d2> 0
In the above case, since the direction of the block in which the user is present is known from the direction of the inequality sign, the direction may be searched.
[0090]
Next, a method for searching for a sector in which the user is present is described. FIG. 17 is a cross-sectional view of a block having a course. Plane JPL1: a1x + b1y + c1z + d1 = 0, plane JPL2: a2x + b2y + c2z + d2 = 0, plane JPL3: a3x + b3y + c3z + d3 = 0, and plane JPL4: a4x + b4y + c4z + d4 = 0 are defined between the sectors constituting the block. The normals of these planes are each parallel to the plane of the sector as shown.
[0091]
As shown in FIG. 17, when the position P (x, y, z) is between the plane JPL2 and the plane JPL3, as described above, the equation of the plane JPL2, JPL3 and the point P (x, y, The following relationship is established during z).
[0092]
a3x + b3y + c3z + d3> 0
And
a2x + b2y + c2Z + d2 <0
As described above, when the coordinate where the user is located is P (x, y, z), if there is a relationship as described above with the planes on both sides of a certain sector, the self (ride) is positioned within that sector. Can be judged. Therefore, in order to specify the sector in which the user is present, the above-described determination may be performed for each sector.
[0093]
JPL1 and JPL4 have the following relationship.
[0094]
a1x + b1y + c1z + d1 <0
a4x + b4y + c4Z + d4> 0
In the above case, since the direction of the sector in which the user is present is known from the direction of the inequality sign, the direction may be searched.
[0095]
1.3.3 Ride and course collision
Next, a description will be given of collision for arranging rides on the course.
[0096]
The ride is a three-wheeled vehicle as shown on the left side of FIG. Therefore, the collision may be determined based on three points. As shown on the right side of FIG. 18, a ride coordinate system # 1 is defined around the position of the ride, and three points C0C1C2 are defined in this coordinate system. The ride is put on the course based on the coordinate system defined in this way.
[0097]
First, a polygon having points C0 to C2 is specified. The specific procedure at this time is the same as the method for specifying the block and sector in which the user is present. FIG. 19 shows the relationship between the ride collision and the course plane. Point C1 and points C0 and C2 touch different sectors. In the ride coordinate system, a vector v2 connecting the point C1 and the point C2 and a vector v1 starting from the point C0 and intersecting the vector v2 are defined, and the ride normal Y is obtained based on these vectors v2.
[0098]
Next, the next position of each point is determined. The next position is obtained from the resultant force of the three forces of force F by acceleration, gravity G, and force P pushing the road surface.
[0099]
For example, when the forces F, G, and P have a relationship as shown in FIG. In addition to the case where the resultant force T is directed on the road surface, the resultant force T may be directed downward as shown in the figure. When the resultant force T faces the road surface, the ride is moved along that direction. On the other hand, when the resultant force T is directed below the road surface, the correction is performed as follows.
[0100]
When the point goes into the course plane, the next position (below the road surface) is moved along the normal line (a, b, c) as shown in FIG. As a result, the position of the ride is properly expressed on the road surface.
[0101]
On the other hand, a force corresponding to the correction amount at this time is stored as a correction force. This correction amount corresponds to the force that the ride receives from the road surface. When this correction amount is made to correspond to the road surface state, it becomes more realistic. Therefore, the acceleration related to this correction is obtained based on F = ma. At this time, by considering a -kx force as the spring constant k (suspension), a so-called rattling feeling can be produced according to the road surface condition. For example, if the road surface is snow, the spring constant k is reduced because it becomes a soft cushion. On the other hand, if the road surface is rock, it is hard and the spring constant k is increased. If it is a dirt road or asphalt pavement, it will be in between. In addition, by providing a spring action depending on the state of the road surface in this way, even when the ride is stopped, the bank of the road surface may rattle.
[0102]
Next, a roll (Z rotation angle) serving as motion ride data and camera rotation data is calculated. In FIG. 19, the outer product of the vector v1 and the vector v2 is obtained and set as the normal line Y. The angle formed between the Y axis of the global coordinate system # 0 and the ride normal Y is obtained. This is the roll angle. Then, a matrix facing the v1 direction is obtained. The ride uses this matrix to direct the direction of the vector v1 and to perform Z rotation with the obtained roll.
[0103]
The related items are described below.
[0104]
Banking is important in the game. Therefore, the wall P that is easy to bank is created by adjusting the force P that pushes the road surface. When the force P that pushes the road surface is large, banking is easy. By creating a wall that is easy to bank, the ride will be easier to rotate.
[0105]
In addition, banking is facilitated by collision with another car operated by another player or automatically operated. By adjusting the reflection coefficient, the force in the x-axis direction of the ride coordinate system when it collides with the other car is adjusted to make it easy to move sideways. If you move to the side of the direction of travel, it will bank, so the motion will rotate greatly.
[0106]
The other car is controlled by turning the handle along a vector that connects the current position and the point of the course center on the block determination plane. If there is an other car on the current block, add an offset to the center of the course and cut the handle.
[0107]
The collision between rides is taken with a ball. That is, a sphere with the ride position P as the center is defined, and collision occurs between the spheres.
[0108]
As described above, the ride receives a force corresponding to the road surface condition, and can jump. At this time, the height of the jump is adjusted by changing the size of the gravity G depending on the location. For example, it is conceivable to change the gravity for each sector so that the gravity of the sector at the center of the course is large and the gravity of the sector around the course is small (or vice versa). It is also possible to take the braking while jumping by changing the gravity applied to the three points of the collision of the ride. By controlling the gravity in this way, the stability of the ride can be ensured and play can be facilitated.
[0109]
1.3.4 Blackout section during the course
As described above, a course in which semi-cylindrical blocks are connected is formed. There is a tunnel in the middle of this course, and this section becomes a blackout section (section that makes the background invisible by overlaying black on the background).
[0110]
The blackout section is not only a scene of the course, but also has the purpose of reducing the burden on the processing unit. The course of Embodiment 1 of the present invention is long, and the ride runs through various terrains such as mountainous areas and forests at a very high speed. In this way, changing the terrain in the middle of the course is necessary to eliminate the monotonousness of the course and to make the game more interesting. For example, when the terrain changes from a mountainous area to a forested area, it is necessary to completely rewrite the material used for background drawing. However, the rewriting speed of the processing unit is limited, and it is difficult to rewrite the background instantaneously. Therefore, an unnatural state during rewriting is displayed on the screen, which may give the player a feeling of strangeness.
[0111]
Therefore, in the embodiment of the present invention, when the background changes, a tunnel is provided in the middle to darken the screen, and the background is rewritten in the background. Even in reality, the terrain often changes greatly before and after the tunnel, so setting this way is not unnatural. Note that the following processing is performed because it may be unnatural if a blackout section is simply provided in the course of the course.
[0112]
In this blackout section, reverse running where the ride runs backwards on the course is prohibited. In normal sections, players with poor skills may run in the opposite direction by mistake. This is one of the fun aspects of the game and usually allows reverse running. However, if reverse running is allowed in the blackout section, it will be unnatural because it will leave the tunnel during rewriting the background and you will see an unfinished background, or a different topography will be displayed. Therefore, in the blackout section, when the ride runs backward by the player's operation, the processing unit automatically changes its direction and runs in the forward direction. Specifically, the normal line n of the plane JBL in FIG. 16 is used. Compared to the ride vector v1 and the normal n of the block judgment plane JBL (for example, the inner product is obtained), if these directions are opposite, it is determined that the vehicle runs backward, and the ride vector v1 is set to the normal direction. Return (for example, reverse the sign of the component in the normal direction).
[0113]
In the blackout section, the processing unit may steer the ride. It's hard to understand how the ride is moving because you don't know the situation in the tunnel. Therefore, it is not so unnatural to ride automatically. If it is autopilot, there is no problem of reverse running. If it is unnatural that the ride moves regardless of the player's operation, the ride may be moved slightly by the player's operation, but at least the direction may be controlled to be forward. .
[0114]
1.3.5 Ride control on the game screen
As shown in FIGS. 7 to 9, two players ride on the ride, and each player moves the operation unit with the right hand and the left hand. Since there are two operation systems in this way, these inputs may not match or contradict each other. Since there is only one ride, it is necessary to reflect it in one ride even when the operation inputs of these two players conflict.
[0115]
Therefore, the following processing is performed regarding the operation of the ride. In FIG. 22, when the direction vector operated by the player 1 is V1, and the direction vector operated by the player 2 is V2, the vector V to be reflected on the ride is a weighted average of V1 and V2. Instead of taking a simple average, a weighted average is taken while placing a weight on the data (V1 in the figure) closer to the vector n along the course. In FIG. 22, it can be said that the player 1 is performing a more appropriate operation than the player 2, and thus, an appropriate ride operation can be realized by such weighting. It goes without saying that a simple average of simple processing may be performed.
[0116]
In addition, the following methods can be considered as weighting. This is a method of weighting each seat. If the front seat 52a is used as an expert (leader) seat, the weight of the control lever 53a is increased. When the rear seat 52b is used as an expert seat, the reverse is applied. In addition, the leader may be determined by voting by the participants, and the weight may be determined.
[0117]
Alternatively, when an illegal operation is performed, the operation may be invalidated. For example, when the operation instruction is reverse running, priority is given to other operations.
[0118]
The above is a method of processing two operation inputs by the processing unit. However, these two operation systems are mechanically connected by a connecting rod, a wire or the like so that one operation signal is input to the processing unit. Good. In this case, since it is necessary to combine the powers of the two operators, it is interesting that cooperation between friends and couples appears in the result.
[0119]
