[0204] Figure 19 An example of the game screen in the first example is shown. exist Figure 19In the figure, the plate objects 71 and 72, the ball object 73, and the wall object 74 are located in the two-dimensional game space. The plate-shaped object 71 is an operation target to be operated by the player. The plate-shaped object 71 can move up, down, left and right on the display screen and can be rotated by the player's operation (such as Figure 19 indicated by the arrow in). Similar to the plate-shaped object 71 , the plate-shaped object 72 is controlled by the CPU 10 of the game device 3 and is movable up, down, left, and right on the display screen and is rotatable. Hereinafter, the plate-shaped object 71 to be operated by the player will be referred to as a "player object", and the plate-shaped object 72 to be controlled by the CPU 10 will be referred to as an "opponent object". The ball object 73 (hereinafter also simply referred to as "ball") moves in the two-di...

[0222] Figure 22 An example of the game screen in the second example is shown. Figure 22 A game scene is shown where a player can open a door with a key. exist Figure 22 , a three-dimensional game space is constructed, and the door 75 and the key 76 are located in the game space. The door 75 has a keyhole 75a. The player can move or rotate the key 76 by operating the controller 7 . The player performs an operation of moving the key 76 in the three-dimensional game space using the controller 7, and thus puts the key 76 into the key hole 75a. When the player performs an operation of turning the key 76 in a state where the key 76 is in the keyhole 75a, the door 76 is opened. Figure 22 The X-Y-Z coordinate system shown in is a coordinate system in 3D game space and is not actually shown on the display. In this example, the Z-axis direction is the depth direction, which is parallel to the viewing direction of the virtual camera.

[0249] Next, game processing in the third example will be explained. In a third example, a three-dimensional game space is constructed, and a virtual camera for generating an image of the game space is set. In the third example, a virtual camera is an operation target. In this example, the processing of moving the virtual camera will be mainly explained, and other game processing will be omitted.
[0250] Figure 27 The game space example in the third example is shown. Figure 27 A virtual camera 81 that rotates or moves along an arc as an operation target is shown. exist Figure 27 In , reference numeral 81 denotes the position and direction of the virtual camera before movement, and reference numeral 81' denotes the position and direction of the virtual camera after movement. exist Figure 27In , set the coordinate system (X-Y-Z coordinate system) that represents the position in the game space. In this coordinate system, the ground 83 is parallel to the X and Z axes, ...
