Abstract

A computer-aided design system and a process generates a graphic display of a blend between a plurality of geometric primitive shapes including other blends. An interactive terminal controls a geometric modeler to generate and modify visual graphic displays of primitive geometric shapes at a display screen of the interactive terminal. Logic structures generate both a blend and blends. Each logic structure is implemented with an individual distinct blending algorithm to accomplish a localized superelliptical blend and blends according to user selections including: a plurality of geometric primitive shapes to be blended, a blend operation, and a blend function. A memory, registers and gates in the system store and manage data.
