I'm in the process of doing some cleaning and moving items over to my new homepage Thus the links under this page may disappear. If you want to come back to them you should bookmark this page instead of the others. Thank you.

Some information about me: I graduated in June 1995 from the University of Minnesota with a Bachelor of Science degree (summa cum laude) in Computer Science. I'm currently at graduate school in the Brown University Computer Science Department.

Current/Past Projects (no particular order):

Non-Photorealistic Rendering of Mathematical Objects
Also known as "UNREAL", the idea of this project is to create a program that can create pen and ink mathematical illustrations from 3D (or higher dimensional) objects.
Geomview FAQ
An attempt to cut down on the volume of questions addressed to the Geometry Center Software Group. This has been taken over by others since my departure.
VR Senior Project
Implemented a virtual environment for investigating manifolds in euclidean, spherical, and hyperbolic space.
A Tk/Tcl frontend to the Persistance of Vision (POV) Raytracer.
University of Minnesota Computer Science WWW server
Part of the team that originally set up the UofM CS server. Control of this has now been passed on to the CS system staff.
Enhancing POV
I have extended the parser to handle transandental functions and command line define. I have also added support for reading and writing PGM and PPM files. This code has been contributed to the POV Team and will appear in POV 3.0. If you want to try the PPM patch, it is available here. Other enhancements I'm considering implementing are variable degree Bezier patches and triangles with colors interpolated from specified corners.
Working with Daeron Meyer on a greatly enhanced version of the Geometry Center's Geomview visualization software.
Genetic Programming
Working on enhancing my Toolkit for Visual Genetic Programming, which was originally written while I was an intern at the Geometry Center's 1994 Summer Research Institute.
