Geometric Modeling

Abstract

A system is presented for modeling three-dimensional objects such as buildings and mechanical devices, in the computer. The system has been implemented as an interactive design system. Shaded, half-tone photographs of objects designed with the system are included: An algorithm is presented for quickly determining if two objects, created by the human user, interpenetrate one another. The user is informed of such violations by the system. Additionally, basic concepts of computer graphics modeling are presented for the benefit of readers not conversant with the terminology of computer graphics. The implementation of these ideas as an interactive design system for architects has been a formidable task on the UNIVAC 1108. A description of this task is included as an Appendix.
