IPC: G06T17/30
Filed: 2000-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a three-dimensional CAD system which reduces the load of computation processing by a computer by greatly decreasing the amount of data and makes the handling of planes consistent. SOLUTION: This three-dimensional CAD system sets basic figure elements (PL, LL, SL, and VL) by using straight line coordinates, area coordinates, or volume coordinate parameters and connects the set basic figure elements continuously to generate a basic figure. The basic figure elements constituting the generated basic figure are deformed while enabled to be continuously differentiated to generate a desirable solid figure (identical topology figure). Thus all planes are approximated and represented by a patch to make the handling of the planes consistent, the amount of data for rendering the figure is greatly reduced, and the load of the computation processing by the computer is reduced. It is decided whether or not an element may be deleted by a reference counter RC showing whether or not the element is a constitution factor for other elements.
