Description

This invention relates to an information processing program, information processing system, information processing device, and information processing method for performing processing that displays an image based on a virtual space as viewed from a virtual camera. Conventionally, technologies for displaying images of a virtual space as seen from a virtual camera have been disclosed (see, for example, Non-Patent Document 1). The technology disclosed in Non-Patent Document 1 reduces processing load by performing back-face culling, which involves not rendering the back-facing faces of a polygon relative to the virtual camera.
