Thereafter, the CPU 1 moves the camera 111 in the Y-axis direction 11 so that the line of sight of the camera 111 intersects the central axis 124 of the virtual cylinder 125 as shown in FIG.
Rotate to 9. Similarly, when the camera 111 is moved in the direction 114, not shown in FIG.
As shown in FIG. 3, the camera 111 is rotated in the direction 118 on the Y axis. After that, the CPU 1 enters the camera 1 in a standby state.
When the object 11 is moved, as shown in FIG. 20, the CPU 1 determines distances 128 and 129 from the XZ plane passing through the intersection of the line of sight of the camera 111 and the central axis 124 of the virtual cylinder 125 to each space area, and , XZ plane and camera 11
The slide amount of each space area is determined in proportion to the angle 127 formed by one line of sight.

Then, the CPU 1 determines that X through the intersection of the line of sight of the camera 111 and the central axis 124 of the virtual cylinder 125
The space area 46 above the -Z plane is turned toward the back, and the space area 47 below is slid toward the user. Thereafter, the CPU 1 enters a standby state.

As shown in FIG. 21, after calculating the coordinates of the movement destination of the camera 111, the line of sight of the camera 111 and the virtual cylinder 1 are calculated.
When the angle 133 between the center axis 124 of the virtual cylinder 125 and the center axis 124 of the virtual cylinder 125 is perpendicular to the angle 133 formed by the center axis 124 of the virtual cylinder 125 as shown in FIGS. While maintaining the space area 46, 4
7 passes through reference points 178 and 179 provided in these areas, respectively, and intersects the line of sight of the camera 111 with the axes 180 and 1 perpendicular to the central axis 124 of the virtual cylinder 125.
Incline at minus 81 degrees around 81. Thereafter, the CPU 1 enters a standby state.

Further, as shown in FIG.
After the movement, the distance 135 between the camera 111 and the central axis 124 of the virtual cylinder 125 becomes D, and if D is larger than the value specified in the storage unit 6, the CPU 1 moves D from the central axis 124 of the virtual cylinder 125 to D. The camera 111 is arranged at the position. Thereafter, the CPU 1 enters a standby state.

As described above, after the camera 111 is moved, the storage unit 6
When D is smaller than the value designated by, as shown in FIG. 25, the CPU 1 calculates an angle θ corresponding to the distance of D, and calculates the angle θ from the intersection between the line of sight of the camera 111 and the central axis 124 of the virtual cylinder 125. With the upper space area 46 facing upward,

Change the diameter of 25 to D. Thereafter, the CPU 1 enters a standby state.

FIGS. 26 to 31 are views for explaining the change of the camera position in conjunction with the change of the viewing angle of the camera.
Hereinafter, these will be described.

As shown in FIG. 26, when the camera 111 arranged in the virtual three-dimensional space projects the target object 138 similarly arranged in the virtual three-dimensional space at a viewing angle 139, Is expanded, other objects around the target object 138 are displayed, and it is easy to grasp the mutual positional relationship. However, if the viewing angle 139 is increased, the size of the appearance of the target object 138 is reduced, and it is difficult to understand what the target object 138 was viewed as.

Conversely, if the viewing angle 139 is narrowed, the perspective of the projected image becomes loose,
The angle at which the surfaces and lines of the respective portions 8 intersect can be seen more correctly. However, when the viewing angle 139 is reduced, the size of the view of the target object 138 increases, so that the visible range other than the target object 138 is reduced.

Therefore, as shown in FIG. 27, the positions of the camera and the subject are changed in the virtual three-dimensional space in conjunction with the change of the viewing angle of the camera. In other words, when the viewing angle 142 is expanded to the viewing angle 142, the camera is moved to the object 1 until the target object 138 does not change in size.
Approach 38. Conversely, the viewing angle 143 is changed to the viewing angle 1
When the distance is reduced to 42, the camera is moved far enough to keep the size of the view of the target object 138 unchanged.

In FIGS. 28 and 29, when the viewing angle of the camera 111 is changed by the user, the CPU 1 sets the line of sight of the camera 111 and the virtual cylinder 12 at the viewing angle before the change.
Then, the coordinates of an axis 175 passing through the intersection 185 of the center axis 124 of No. 5 and perpendicular to the center axis 124 and the line of sight of the camera and the intersections 182 and 183 of the visual field edge of the camera 111 are obtained. And CP
U1 is the line of sight of the camera 111, the intersection 185 of the central axis 124 of the virtual cylinder 125, and the camera 111 before the viewing angle is changed.
On the line connecting the position of
Camera 111 whose intersection with 75 coincides with 182 and 183
Is obtained, and the camera 111 is moved to the obtained position. Thereafter, the CPU 1 enters a standby state.

In the above description, the operation of moving the camera 111 has been described. When the camera 111 is moved to a preset camera position, a state in which an object is viewed while the camera is moving is shown by animation. You can do so.

Assume that the user issues an instruction to change the position of the camera 111 from the current position 170 to a preset position 171 as shown in FIG. In such a case, in order to understand the relationship between the current position 170 and the moved position 171 using animation, the CPU 1 sets the travel distance 186 from the current position 170 to the moved position 171. calculate.
Usually, in the animation processing, the moving distance 187 between the frames of the animation from the start to the end of the movement.
Is constant, if the travel distance 186 from the current position 170 to the position 171 after the movement increases, the number of frames of the animation increases, and as a result, the movement time increases. If the presentation time of a frame is increased to shorten the time required for movement, it becomes difficult to recognize the animation as a smooth animation. If the movement distance 187 between frames of the animation is increased, it is possible to move at high speed immediately after the start of movement. Because it is visible, it is difficult to grasp the relationship between the current position 170 and the moved position 171.

Therefore, as shown in FIG. 31, in the period 172 immediately after the start of the animation, the moving distance between frames of the animation is gradually increased, and the period 17 immediately before the end of the animation is changed.
By gradually decreasing the moving distance between frames of the animation in step 4, the animation is visually accelerated and decelerated. Therefore, in the middle range 173, the moving distance 189 between the frames of the animation is set.
Is larger than the moving distance 187 in a fixed case as shown in FIG.
Understanding the relationship with 71 is not compromised. As a result, in a state where the relationship between the position before the movement and the position after the movement can be grasped,
In addition, the time required for moving the camera can be shortened.

The processing of the CPU 1 when performing the above-described animation will be described below. It is assumed that the user issues an instruction to change the position of the camera 111 from the current position 170 to a preset position 171.
First, the CPU 1 calculates a moving distance 186 from the current position 170 to the moved position 171. CPU1
The moving distance 187 between frames of the animation when the moving speed is constant is read from the storage unit 6. CPU1
From the movement distance 187 between the animation frames and the travel distance 186, the animation frames necessary for the movement when the movement speed is constant are calculated.

After that, the CPU 1 reads from the storage unit 6 the rate of increase and decrease of the moving distance between frames, the minimum ratio of the section where the moving distance is constant in the entire travel distance, and the maximum value of the moving distance between frames. . The CPU 1 uses the minimum rate of the section having a constant moving distance in the entire distance, and the maximum value of the moving distance between frames, based on the increasing rate and decreasing rate of the moving distance between frames of the animation and the distance 186. To minimize the total number of frames,
The acceleration section 172 immediately after the start, the middle constant velocity section 173,
The number of frames in the deceleration section 174 immediately before the end is calculated.

The CPU 1 compares the number of frames of the animation when the moving speed is constant with the number of frames of the animation when the acceleration / deceleration is performed, and adopts the one with the smaller number of frames. The CPU 1 determines the position, the line-of-sight direction, and the camera direction of the camera 111 that displays each frame, the position 171 after movement from the current position 170 and the movement distance between each frame in accordance with the adopted method, the center axis of the virtual cylinder, The animation is executed using the position of the camera 111 calculated for each frame and the gaze direction (the direction of the camera) calculated for each frame. Thereafter, the CPU 1 enters a standby state.

The position of the camera 111 is determined by the buttons 94 to 1 provided on the camera operation display unit 23 shown in FIG.
03 can be controlled. That is, the buttons 94 and 96 are used for control of moving the camera 111 in the vertical direction, and the buttons 95 and 97 are used for controlling the camera 111.
Is used for the control to move horizontally in the circumferential direction. Buttons 98 and 100 are used to control the vertical direction of the camera 111, and buttons 99 and 101 are used.
Is used for controlling the left-right direction of the camera 111, although it is not necessary in the present invention.

In the above description, as shown in FIG.
U1 first generates a virtual cylinder 125 that is not captured by the camera in the virtual three-dimensional space 110 using a central axis 124 parallel to the Y-axis of the virtual space, and places the inside of the cylinder on the circumferential side surface of the virtual cylinder 125. Aim the camera. After changing the position of the camera 111, the CPU 1 changes the circumferential radius 126 of the virtual cylinder 125 so that the camera 111 is located on the circumferential side surface of the virtual cylinder 125.

When a space area is generated by the virtual cylinder 125, the CPU 1 sets the space area to the virtual cylinder 1
It is arranged at the center on the central axis 124 of 25. Virtual space 46
Exists, and the virtual space 47 is additionally generated, the CPU 1 arranges the virtual spaces vertically in the Y-axis direction at intervals.

The CPU 1 sets the height of the virtual cylinder 125 to a value calculated based on the height from the upper surface of the uppermost space area to the lower surface of the lowest space area. When changing the height of the virtual cylinder 125 by adding or deleting a space area, the CPU 1 determines that the center of the range from the upper surface of the uppermost space area to the lower surface of the lowermost space area is the center of the virtual cylinder 125. The intersection 18 between the line of sight of the camera 111 and the central axis 124 of the virtual cylinder 125
With reference to 5, the height of the virtual cylinder 125 is expanded or contracted to the side where the space area is added.
