<p><P>PROBLEM TO BE SOLVED: To enable a suitable collision determination according to a situation while suppressing the increase in amount of computation required for collision determination. <P>SOLUTION: As for an object of a dog in a virtual three-dimensional space, according to the state of the dog or its periphery, for example, this device sets up as a collision determination region a sphere with the center at the chest part of the dog on all fours and with the radius of 30, sets up as another collision determination region a sphere with the center at the waist part of the standing dog and with the radius of 10, and sets up yet another collision determination region a sphere with the center at the head part of the dog being playing with another dog in the virtual three-dimensional space and with the radius of 10. Using thus set up collision determination regions, collision determination with other objects is performed. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
