Here are some projects I worked on while I was a graduate student. They were mostly joint work.

Getting LATERNA matheMAGICA ready for Supercomputing 95 took most of my time in summer 1996. It consisted of four parts, the most important of which used Ken Brakke's Evolver program (running on a Cray or a Power Challenge Array) to evert a sphere, by starting at a halfway model and computationally evolving the Willmore bending energy to it's minimum. This was the first geometrically optimal and automatic eversion of the sphere. Also, see the NCSA Access article on stuff we sent to SC '95.

[UAF Logo]In December, 1995, I gave a seminar at the University of Alaska, Fairbanks mathematics department on "Mathematics and the CAVE." It is listed on the UAF DMS Colloquium Series web page. See Dave Pape's page for more about the CAVE.

Snail, one of the early CAVE applications I worked on has been translated into VRML. You can find it (and other CAVE VRML programs) on the CAVE VRML web page.

Chesapeake Bay is a project from both VROOM at SIGGRAPH '94 and from Supercomputing 95. See the VROOM Chesapeake Bay page.

Cellular Semiotics is a project I worked on for Supercomputing 95. You can also read a little about it on the GII testbed page devoted to Biological and Medical Imaging.

[hyperbolic space][spherical space]Post-Euclidean Walkabout is another VROOM project from SIGGRAPH '94. I wrote most of the CAVE code for this expedition into non-Euclidean spaces. Also, see the NCSA Access article.

Last (and probably least), check out Improving Graphical User Interfaces for Computer Music which is "a plea to the computer music community to aim higher in the development of new graphical tools and better graphical user interfaces (GUIs) for computer music applications." It references a paper I co-wrote where we use interactive computer graphics to display and modify the spectral surface of a sound.
