Patent ID: 7643028

Claim:
A computer-readable storage medium storing instructions which, when executed by a processor, perform a method for generating an image of a virtual three-dimensional space viewed from a virtual camera, the method comprising steps, performed by the processor, of: arranging a model configured by intersecting a plurality of plate-shaped polygons in said virtual three-dimensional space; calculating a parameter dependent on an angle formed from a first vector set in association with said model and a second vector set in association with the line of sight of said virtual camera; selecting as a display target one among said plurality of plate-shaped polygons configuring said model according to said parameter; mapping a prescribed texture to said plate shaped polygon selected with said polygon selection unit; and generating a two-dimensional image obtained by performing perspective projection to the inside of said virtual three-dimensional space, in which said model mapped with said texture is arranged, on a perspective projection plane set in correspondence with a visual point of said virtual camera.
