Claim One:
1. A collision detection system comprising: a processing section; a drawing section adapted to perform a drawing process; and a depth buffer to which depth information is set, wherein the depth information of an object arranged on a target side is set to the depth buffer as depth map information, the drawing section performs a first drawing process of performing a depth test, and drawing a primitive surface on a reverse side when viewed from a predetermined viewpoint out of primitive surfaces constituting a collision detection target object with reference to the depth map information in the depth buffer, and a second drawing process of drawing the primitive surface on the reverse side when viewed from the viewpoint out of the primitive surfaces constituting the collision detection target object without performing the depth test, and the processing section performs collision determination of determining whether or not the collision detection target object collides with the object on the target side based on a result of the first drawing process and the second drawing process.
