Work Period 1992 – 1996

Interactive Simulation of Contaminant Evolution through Porous Media, 1996

Masters Thesis, 1995-1996

Parallel Progressive Refinement and Projection Based Discontinuity Meshing for Radiosity

This image shows how the rendering codes that I wrote for my thesis work were used to create a more efficient (discontinuity) mesh that followed the shadow boundaries of the illuminated triangle.

Radiosity, 1995

The table below shows some radiosity scenes that I rendered with codes that I wrote. Pagoda Room was displayed in the CAVE® Automatic Virtual Environment theatre[1] at the Supercomputing ’95 conference.

The “Jon’s Home” image demonstrates the ability of my codes to export a triangular mesh from Open Inventor files and render them with my radiosity renderer.

We rendered radiosity images in the CAVE. The following image is a plain old vanilla OpenGL rendering of the CAVE [2] .


You can read lots about the CAVE by following this link to Dave Pape's CAVE site. He was CAVE master at EVL... roughly in the years of 1994 -to- 1999 or 2000.

Gravitation and Astrophysics, 1993-1995

A scientific visualization package that Trina Roy[3] and I developed to aid NCSA Urbanna/Champagne astrophysicists and relativity scientists examine the output of their simulations.

Worm related articles and images can be found here.

Argonne, 1994

For a brief period while in Graduate School, I worked as a Research Associate at Argonne National Labs, in Argonne Illinois. The main project I did there was to develop an Inventor/OpenGL-based CAVE viewer for data visualization of subsurface pollution.

Ray Tracing, 1992

When I first arrived at the EVL, I wrote some ray tracing codes (also in C, using Irix GL), and rendered the image shown below.

[1] The CAVE was developed at the Electronic Visualization Laboratory (EVL), The University of Illinois at Chicago, under the direction of Tom Defanti and Dan Sandin, around 1991. At that time it was a 10’ x 10’ x 10’ cube, rear illuminated with up to four Electrahome projectors, one for the front wall, one for the left, one for the right, and one for the floor. The CAVE was typically driven by Silicon Graphics Onyx graphics computers.
