Abstract:
1. A computer-readable storage medium storing an image processing program to be executed by a computer of an image processing device for displaying, on a display device, a virtual three-dimensional space where there are a plurality of objects each having a cylindrical collision detection region defined therefor, wherein the image processing program instructs the computer to perform: an inclination angle calculation step of calculating an inclination of an object with respect to a predetermined reference direction in the three-dimensional space; a number-of-regions determining step of determining the number of cylindrical collision detection regions to be defined for the object according to the inclination of the object; and a collision detection region defining step of defining the determined number of collision detection regions for the object in an arrangement being determined according to the inclination of the object so that a bottom surface of each of the collision detection regions is perpendicular to the reference direction.
