Ray Tracing and Graphics Extensions

This page contains pointers to some supplemental material for the article Ray Tracing and Graphics Extensions [Maeder94e].

Abstract

A special data type for surfaces in space maintains important connectivity data and surface normals. The new data type is especially important for preparing ray-tracing input from Mathematica graphics. We present conversion utilities for two popular ray-tracing programs.
