Abstract
A method of determining collision occurring in a virtual space generated by a system using a computer includes the steps of preparing, for drawing data approximating a virtual object in the virtual space by a plurality of rectangular parallelepipeds, machine readable first shape data for collision determination approximating the virtual object by a plurality of rectangular parallelepipeds smaller in number than rectangular parallelepipeds of the drawing data, and determining, as a prescribed point moving in the virtual space moves, whether the prescribed point and the virtual object satisfy a predetermined collision condition or not, based on a coordinate of the prescribed point in the virtual space and the first shape data, by computer calculation. An apparatus for implementing this method is also disclosed.
