Half-Tone Perspective Drawings by Computer

Abstract

The paper is a brief description of an algorithm for the creation of two-dimensional, half-tone pictures of perspective projections of three- dimensional objects. Only the visible surfaces are displayed; all hidden surfaces are erased. This process is independent of the orientation of the object. The inclusion of half-tone shading was considered important because the illumination of an object gives a viewer much information about the three- dimensionality of the object. A FORTRAN 4 program is working on a UNIVAC 1108. Preliminary results indicate that his approach is not only possible, but practical for complex objects. Processing time is small and storage requirements are very compart.
