Abstract

In this paper, we describe STREN, a parallel stereo renderer for fixed-location terrain rendering tasks required for the simulation of planetary exploration missions. The renderer is based on a novel spatial data representation, called the TANPO map. This data representation stores terrain data using a simple and compact structure and provides excellent locality for such rendering applications. Experimental results show that the renderer not only performs very well, but also scales perfectly to different numbers of processors.
