An interactive three-dimensional color graphics system

Abstract A three-dimensional image handling system is described for the interactive construction and manipulation of color images defined by polygon concatenation. The human operator, who has limited knowledge of the system, is provided interactively with a wide range of options for realizing a desired construction on a vector display. The images thus created are displayed on a color scan conversion subsystem. The specific application of this system is for the generation of three-dimensional solid forms in color with the system optimized in favor of human engineering principles.
