ABSTRACT:
A graphic workstation converts a polygonal model generated with computer aided design (CAD) software or volumetric data into a more compact polygon strip list having multiple strip sublists. The strip list, in addition to being more compactly stored, is displayed much more rapidly than conventional polygonal models since much of the redundant redrawing is eliminated. Shared point of adjacent polygons are eliminated. The strip list consists of a number of strip lists, each list having vertices of a first, or initial, polygon and subsequent vertices defining remaining portions of polygons to be `built onto` the polygon strip in the strip direction. Since this method of model storage and display is much more efficient, less powerful graphic workstation could be implemented in place of more powerful graphics workstations; or alternatively, existing graphics workstation would become faster and have more free memory available for other functions.
