摘要

It is intended to display, in a 3D-CG animation, a high-quality background image that is free of distortion due to a pan of a viewing camera. Pre-rendering images of three-dimensional background scenes are mapped over the inside surfaces of respective virtual spheres 70ak-1 and 70ak, and viewing cameras 71ak-1 and 71ak are defined at the centers of the respective virtual spheres 70ak-1 and 70ak. When a three-dimensional model of a movable object such as a character model enters one of the virtual spheres, a region clipped by the pyramidal visual field of the viewing camera located at the center of the virtual sphere is projected onto a display screen. <IMAGE>
