Abstract
An image generating apparatus displays a highly expressive display of a polyhedron representing an object made from a pliable material using only a very small computational load. The image generating device displays images of polyhedrons located in a virtual space and includes a mass point setting circuit setting mass points across an entire surface of a polyhedron, an influential force setting circuit setting influential forces acting on the mass points, a mass point position calculating circuit calculating the positional coordinates of the mass points on the basis of the influential forces set by the influential force setting circuit; and a figure generating circuit generating a figure of the polyhedron on the basis of the positional coordinates for the mass points calculated by said mass point position calculating circuit. Since the positional coordinates of mass points are calculated on the basis of influential forces which simulate the forces acting on a real planar object, it is possible to generate a figure of a polyhedron which moves like a real, pliable planar object.
