A computer-readable storage medium having stored therein a program for displaying a plurality of polygons disposed on 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 display means, a step of outputting an entire view volume image stored in an (N-i)-th frame in display-purpose storage means to the display means; a step (S30 through S32) 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 to generate a first view volume image; and a step of storing the first view volume image in non-display-purpose storage means, 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 to generate a second view volume image, and combining the second view volume image and the first view volume image stored in the non-display-purpose storage means together to generate an entire view volume image; a step of outputting the generated entire view volume to the display means; and a step of storing the generated entire view volume image in the display-purpose storage means. (a) in an N-th frame where one frame is taken as a display updating period of display means, a step of outputting an entire view volume image stored in an (N-i)-th frame in display-purpose storage means to the display means; a step (S30 through S32) 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 to generate a first view volume image; and a step of storing the first view volume image in non-display-purpose storage means, and a step of outputting an entire view volume image stored in an (N-i)-th frame in display-purpose storage means to the display means; a step (S30 through S32) 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 to generate a first view volume image; and a step of storing the first view volume image in non-display-purpose storage means, 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 to generate a second view volume image, and combining the second view volume image and the first view volume image stored in the non-display-purpose storage means together to generate an entire view volume image; a step of outputting the generated entire view volume to the display means; and a step of storing the generated entire view volume image in the display-purpose storage means. 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 to generate a second view volume image, and combining the second view volume image and the first view volume image stored in the non-display-purpose storage means together to generate an entire view volume image; a step of outputting the generated entire view volume to the display means; and a step of storing the generated entire view volume image in the display-purpose storage means.
