Abstract:
A simulation apparatus which performs collision computations for a moving object which moves in a virtual three-dimensional space with respect to a target object which is present in said virtual three-dimensional space and is a subject of collision, said simulation apparatus comprising:decision region defining means for defining a decision region which specifies a three-dimensional space for collision decision based on at least the entire shape of said target object and a portion thereof; andcollision decision means for deciding whether a collision has occurred or not, based on whether or not the position of said moving object is located within said decision region;wherein said decision region defining means defines a three dimensional negative hit region, a portion of which overlaps the positive hit region which specifies a noncollision region for said decision region; andsaid collision decision means decides that no collision has occurred when the position of said moving object is located within said noncollision region for said decision region.
