A little about Me:
I am graduating from the University of Utah in Computer Science, and my wife and I are expecting our first baby. (It's a girl!)
Research:
I'm a ray tracing addict. I would say everyone at SCI is part of a ray tracing motley crew.

Research Software:
Nenners a image processing library for n dimensional data. This library also comes with power apps. The cadillac app of this library is self titled "Nenners" which is a hardware and software volume renderer. The volume can be inspected from the hardware renderer and then when all the parameters have been customize the user can instantiate the software render to create a beautiful high resolution 3D rendering. Animation controls have also been implemented to allow for rendering video from the software renderer.
Eve is a path tracer and volume renderer that I have written. It is a multi-processor ready application, built to use for reseach from image synthesis to multi-dimensional transfer functions. Soon it will support visualization of diffusion tensor MRI scans. This little bad boy ROCKS!! You may request the source code from me by email. It is under the GNU license, and comes "AS IS". You may make modifications to it as you wish and share with others. Email me with anything creative that you've done with it.
Atum is a adaptive temporal tone mapping application. It reads video files, applies multiple tone mapping operators, and outputs a new video file. Atum is extremely fast and can render up to 30 fps on a 400 MHtz processor. Pre-built and source code versions are also available by email. It is under the GNU license, and comes "AS IS". You may make modifications to it as you wish and share with others.
