ABSTRACT:
A computer graphics system and method for capping a polyhedron made up of a plurality of polygons after the polyhedron has been sectioned by a designer to thereby provide a realistic display of the polyhedron. The computer graphics system first comprises at least one processor and at least one memory unit configured with the computer graphics system to process data. The computer graphics system further comprises an input device configured with the computer graphics system to allow the designer to specify the at least one sectioning plane. The computer graphics system further comprises a polyhedron capping module configured in the computer graphics system to instruct the at least one processor how to section and cap the polyhedron against the sectioning plane. The computer graphics system further comprises a display device configured with the computer graphics system to display the capped polyhedron.
