Alejo Hausner: Research

I'm interested in software visualization and computer graphics.

Visualization

My PhD work concentrates on Algorithm Animation. David Dobkin and I have written an introduction to the subject. I have also developed a portable, general-purpose animation system, which I've called Gawain.

Gawain is written in Java, and can be used in several ways:

  1. as an applet, illustrating algorithms on web pages.
  2. as a standalone application, for developing animations.
  3. as a front-end to a GL renderer, for making high-quality video animations.
Gawain's source code and documentation are available.

Computer Graphics

I'm also interested in the use of clusters to speed up the computations involved in radiosity and raytracing. I've worked out a way to simplify a complex extended light source using a multipole expansion.

My Master's thesis in computer graphics presented a method for estimating the cost of raytracing a bounding volume hierarchy using a random-walk model.
