Abstract

A system of constructive solid geometry (CSG) enables an engineering desiger to compose three dimensional (3D) shapes by combining simpler ones. Most existing systems, however, actually represent solid shapes as boundaries of surface patches. At the Kunii Laboratory, University of Tokyo, we have produced an experimental system in which solids are modelled functionally by procedures which describe their properties. These “primitive objects” are combined with the aid of a new “octree” structure. Careful study of the data structures in this system reveals some interesting aspects of program efficiency.
