My Research

These following pages describe my work-in-progress. The general idea is to show results to colleagues and family members who are interested. Unfortunately, they tend to get updated least towards the end of semesters and as paper deadlines approach, which is when the best pictures are generated.... An overview of my research interests is listed below.

Fall 2003 Work: Global Illumination on Isosurfaces	Summer 2003 Work: Global Illumination on Isosurfaces	Spring 2003 Work: Soft shadows and Caustics
Fall 2002 Work: Soft shadows	Summer 2002 Work: Soft shadows	Spring 2002 Work: Caustics
Fall 2001 Work: Caustics	Summer 2001 Work: Caustics	Spring 2001 Work: Caustics
Fall 2000 Work: Interreflections	Summer 2000 Work: Interreflections

I also worked on the Star-Ray Interactive Ray-tracer demo for SIGGRAPH 2002.

My reseach interests fall into three categories (from broadest to most specific):

1. Photorealistic Rendering
   1. Illumination
   2. Simulation (e.g., dust, dirt, fog, smoke, water)
   3. Human perception and computer graphics
2. Global Illumination
   1. Monte Carlo path tracing, photon maps, radiosity
   2. Shadows, caustics, diffuse interreflections
   3. BRDFs
3. Interactive Rendering
   1. New and improved rendering techniques using graphics hardware
   2. Raytracing on shared memory machines and PC clusters
