A Procedure for Detecting Intersections of Three-Dimensional Objects

Abstract

As a step toward the solution of the placement problem in engineering design, a procedure has been developed for detecting intersections of convex regions in 3-space by means of a pseudocharacteristic function. The mathematical techniques underlying the procedure are discussed, and a system of programs embodying these techniques is described. As a special case a solution is given for the hidden-line problem in graphic display. © 1968, ACM. All rights reserved.
