<P>PROBLEM TO BE SOLVED: To eliminate a valley of a hit determination model of an expandable and bendable object, and to apparently prevent such a state that the other object is apparently stuck into the expansion object. <P>SOLUTION: The hit determination model of an expansion object is formed by linearly arranging a plurality of round cylindrical bone elements 4 each of which is formed by connecting hemispheres 4b to both ends of a cylinder 4a as the basic unit of a hit determination region, and connecting the bone elements 4 with the bottom face centers P of the spheres 4b faced to each other between adjacent bone elements as connection points within a prescribed allowable range with a variable relative angle. The overlapped section of the hemispheres 4b is formed as the ball-shaped joint, and even when the expansion object is bent, it is possible to suppress the generation of the interval or valley section of the hit determination region at the outside section of curvature. <P>COPYRIGHT: (C)2010,JPO&INPIT |
