CAMERA CONTROL METHOD, GAME DEVICE, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To make movable the position of a camera by different amount depending on a moving direction by an operation input. SOLUTION: The position of a camera in a virtual three-dimensional space is moved along a reference route R0 (points P1 to P5) in accordance with reference camera data. An observation point T, an angle of viewθand a roll angleαare also automatically set to desired values in accordance with the movement. Four variation camera data for designating routs R1 tio R4 deviated upward and rightward, downward or leftward from the reference route R0 are prepared. When a player instructs a camera to move, the camera is moved from a reference camera position P3 to a position P31 designated by the variation camera data corresponding to an instructed moving direction. The movement threshold of the camera is set to a desired value depending on the camera moving direction and time. Each variation camera data designates the desired values of the observation point T, the angle of viewθand the roll angleαafter the camera moves.
