A vacation on Mars-an artist's journey in a computer graphics world

Abstract

This note provides several artistic examples of landscapes produced on a graphics supercomputer. The shapes were created using a single graphics primitive, and rendered using lighting and shading facilities of 3-D extensions to X-windows and the PHIGS+ proposed graphics standard. In order to encourage reader involvement, this informal article also provides several simple numerical recipes for computing the forms in the paper. © 1992.
