Patent ID: 7161600

Claim:
A computer-readable recording medium having recorded therein a video game program for transforming, in a virtual three-dimensional space, a three-dimensional object having a form at least a part of which is determined by a plurality of vertexes associated with a cluster, said computer-readable recording medium having recorded therein a program for causing a computer to acquire, in each frame display period, an amount of parallel movement of said cluster according to animation data defining a movement of said three-dimensional object and including an amount of parallel movement of said cluster in a plurality of frame display periods, wherein the amount of parallel movement is defined by an amount of movement of said cluster in each of the three-dimensions of the virtual three-dimensional data space; and calculate an amount of parallel movement of each said vertex by, for each vertex of said cluster, multiplying the amount of movement of said cluster in each of the three dimensions of the virtual three-dimensional space by a weight predefined for that vertex, and moving, according to these calculated amounts of parallel movement, said vertexes parallel to each other in each said frame display period.
