Abstract
The present invention provides a 3D real-time graphics generator for generating progressive polygon data for rendering 3D graphics that can reduce the amount of data processing by a computer and a storage area for polygon data, facilitates editing of an object by using the progressive polygon data so as to reduce the amount of work of an animator. The progressive polygon data includes information about vertices of a basic polyhedron approximate to a shape of a 3D object and information about detailed vertices of a polyhedron in a level of approximation to the object that is higher than the basic polyhedron, which are determined progressively based on the level of approximation. In the generation of 3D real-time graphics, detailed vertices are sequentially merged into the vertices of the basic polyhedron so as to produce 3D polygon data.
