Research

My research interests include Global Illumination, Virtual Environments, Non-Photorealistic Rendering, and Graphics Hardware. I am am affiliated with the EVE research group and the ARGH group.

I am writing up a portion of my reaserch as a PhD dissertation! Look for it soon on the NY Times Bestseller List!


An Incremental Weighted Least Squares Approach To Surface Light Fields. Greg Coombe and Anselmo Lastra. Graphics Research and Applications (GRAPP) 2006.

This project continued our work on the incremental capture of surface light fields by using techniques from scattered data approximation. Here is a webpage describing it.
Online Construction of Surface Light Fields Greg Coombe, Chad Hantak, Anselmo Lastra, and Radek Grzeszczuk. 2005 Eurographics Symposium on Rendering.

This project focused on incrementally capturing the surface appearance of models. It was presented at Eurographics Symposium on Rendering 2005. Here is a webpage describing it.
Radiosity on Graphics Hardware. Greg Coombe, Mark Harris, and Anselmo Lastra. Graphics Interfaces 2004.

This project focused on accelerating progressive refinement radiosity using programmable graphics hardware. It was presented at Graphics Interfaces 2004. Here is a webpage describing it.

Physically-Based Visual Simulation in Graphics Hardware. Mark Harris, Greg Coombe, Thorsten Scheurman, and Anselmo Lastra. Eurographics Graphics Hardware Workshop. Sept 2002.

Check out Mark Harris's CML webpage.


Recently, I've been looking into ambient occlusion techniques. Here is a short write-up.

Computer Vision Techniques for Painterly Rendering.  Bruce Gooch, Greg Coombe, and Peter Shirley. Conference on Non-Photorealistic Animation and Rendering. June 2002.

For more description of what I've been doing the first couple of years of graduate school, look at my classwork web pages.

Other Stuff

Here is some random computer stuff that I've figured out over the years, including some code for multi-dimensional SVD.
