Patent ID: 7148894

Claim:
An image generation system for generating an image of a three-dimensional object formed by a plurality of parts visible from a given viewpoint within a three-dimensional object space, comprising: a memory which stores a program and data for image generating; and at least one processor which is connected to the memory and performs processing for image generating, the processor performing: playing a motion of the three-dimensional object formed by a plurality of parts based on pre-stored motion data; generating the motion of the three-dimensional object through a physical simulation; switching processing from a play of the object's motion based on the pre-stored motion data to a generation of the object's motion through a physical simulation when the object is hit; and generating a connecting motion based on interpolation of the motion generated by the physical simulation and the motion played based on the pre-stored motion data, the connecting motion connecting the motion played based on the pre-stored motion data with the motion generated by the physical simulation.
