Abstract:

A computer procedure for generating line drawings of solid objects bounded by quadric surfaces is described. It embodies an efficient solution to the hidden-line problem, that is, the problem of determining which parts of an opaque object are invisible when the object is viewed from a given vantage point. A view of a quadric object is represented by the orthographic projection of surface boundaries visible from the given vantage point. The procedure is implemented in a FORTRAN program and can be extended to do perspective drawing and shading it may be used as the basis of a system for interactive computer-aided design of solids on a CRT display console.
