Patent ID: 7391417

Claim:
A computer-readable storage medium having stored therein a program for displaying a plurality of polygons distributed throughout a game space, which is a three-dimensional virtual space, based on a view point set in the game space, the program causing a computer to perform steps comprising: (a) in an N-th frame where one frame is taken as a display updating period of a display, a step of outputting an entire view volume image stored in an (N−1)-th frame in display-purpose storage locations to the display; a step of rendering polygons included in a first view volume, which is one of two view volumes obtained by dividing an entire view volume, which is an area in the game space to be displayed, into two parts, to generate a first view volume image; and a step of storing the first view volume image in non-display-purpose storage locations, and (b) in an (N+1)-th frame, a step of rendering polygons included in a second view volume, which is another one of the two view volumes obtained by dividing the entire view volume into two parts, to generate a second view volume image, and combining together the second view volume image and the first view volume image, stored in the non-display-purpose storage locations, to generate an entire view volume image; a step of outputting the generated entire view volume to the display; and a step of storing the generated entire view volume image in the display-purpose storage locations.
