Image processing device and recording medium for collision detection

摘要

An image processing device for judging the collision between a first object moving within a virtual space and a second object (201, 202, 203) arranged within said virtual space, comprising:
storage means for storing, upon said virtual space being partitioned per unit grid (51, 52, 53) pursuant to three-dimensional coordinates, said second object existing within said unit grid in correspondence with each unit grid; and
collision judgement means for performing a step of judging the unit grid in which said first object exists and a step of judging the collision between the second object in the unit grid in which said first object exists and the first object.
