WINSOM - A GENERAL SURFACE DRAWING PROGRAM.

Abstract

A program is described that produces realistic representations of surfaces on a raster graphics terminal. The program uses a spatial sub-division algorithm similar to that of Woodwark and Quinlan. Simple geometric primitives, such as spheres, cones, cylinders and cuboids, are combined to build more complex pictures. This paper describes the program and its application in 3-D modelling.
