Orion Lawlor's PhD Thesis: Impostors for Parallel Interactive Computer Graphics

Campus Rendering Antialiased Soft-Shadow Tree

This page describes my parallel programming and computer graphics work on impostors, which are 2D texture standins for real 3D geometry. Impostors provide a substantial amount of latency tolerance and rendering speedup, which can be used to render huge and detailed models--like a model of the entire UIUC campus--with quality antialiased rendering techniques, including soft shadows.

The best places to learn more about these techniques are:
