Projects

• Ray Differentials
  
  This SIGGRAPH 99 paper entitled Tracing Ray Differentials describes a novel algorithm for keeping track of an approximation to a ray's footprint based on derivatives of the ray with respect to the image plane. Among other things, this is useful for texture footprint calculations in a ray tracer.

• Graphics Architectures
  
  This is the main project with which I am involved, which focuses on interactive parallel API for interactive computer graphics (SIGGRAPH 98), a texture prefetching architecture that works in conjunction with caching (Graphics Hardware 98), and a study of parallel texture caching (Graphics Hardware 99)

• Texture Replacement through Image Synthesis
  
  This is an ICIP 1997 paper that came out of a final project for Stanford's Psych 267 (aka CS 348D) class (which I took in Fall 1996). Lucas Pereira and I worked on this together, and we tied with another group for first place in the course's final project competition.

• Lacquered Guitar
  
  This is my final project for Stanford's CS348B class, which I took in Winter 1995. It won me first place in the course rendering competition.

Interests

• Guitar
  Although I enjoy playing other styles, my current kick is Flamenco guitar. Check out my favorite Flamenco Sites. Or else, check out the home page I've set up for my guitar teacher Mariano C�rdoba.
