I was a graduate student at the University of North Carolina at Chapel Hill's Department of Computer Science from August 1997 - December 2002. I've since graduated and moved on to Sandia National Laboratories where I'm working on GPU-accelerated visualization of gigabyte-sized data sets.
My projects while I was a student at UNC included the following:
- Spatial video encoding, a generalization of MPEG2 video compression to handle images of 3D environments where world-space locations are known for each pixel (see the Publications page for relevant papers)
- COMP 96, Computers and Society -- I was the instructor for this course during Summer Session 2, 2001.
- Walkthrough Research Group - massive model rendering at interactive frame rates. I work mainly on resource management and efficient representations for distant geometry.
- Spatial Encoding Research Group - exploiting spatial relationships between images and geometric data. My thesis work fits into this group.
- Interactive Proximity Queries in Massive Models - graph partitioning and ordering applied to tolerance verification in a massive model. See the publications page for the Eurographics paper and associated media.
- Global Illumination - a hobby (see Ray Tracing, below) which turned out to be a neat research topic.
- Fall 1998: COMP 290-72 Project (Far Field Video)
- Fall 1999: COMP 238, Raster Graphics
- Spring 1999: TREMBLE (COMP 145) - lightning reconstruction via thunder analysis.
- Fall 1999: I taught a minicourse on GLUT and GLVU. The slides from the presentation are available in PowerPoint format or HTML.
Before coming to UNC I graduated from Northwestern University in 1997 from the then-new Department of Computer Science. While I was there, I worked on:
- Neverworld - Web-accessible multiuser, multimedia virtual environment
- Scheme48 - porting a Unix-based Scheme interpreter to Windows for the introductory programming classes' use
- SIMGEN - self-explanatory simulators for physics education
My resume (PDF) is available. My publications are on a separate page.
In my daily five minutes of spare time, I do the following:
- Raytracing
- Paper Geometry - a few links for things like origami sites, geometric slide-togethers, and modular origami
- Origami Tessellations
