Rendering

Current infrared (IR) ship signature codes have some limitations in accurately predicting ship IR signatures. They either model general BRDF while ignoring multi-reflections, or compute multi-reflection with simplified BRDF models. In this project we apply state-of-the-art global illumination models to accurate simulate the general case for low observable targets. (Funded by Office of Naval Research)

This project involved combining radiosity and ray tracing to generate realistic images, with special attention paid to specular-to-diffuse transfer of illumination. This project led to the MS thesis of Larry Gritz.

Some of the ideas from this research were incorporated into the Blue Moon Rendering Tools, a RenderMan-compliant rendering system which supports ray tracing and radiosity.
