Nathan Carr
Research Scientist

I am a researcher at Adobe Systems, Inc. working on computer graphics related topics. I joined Adobe after completing my Ph.D. from the Department of Computer Science at the University of Illinois Urbana-Champaign under the guidance of John C. Hart. My interests range from image and geometry processing, to computer graphics. My primary areas of focus have been in rendering, graphics hardware, and geometry processing. My thesis focused on techniques for mesh parameterization with an emphasis on making them useful for accelerating surface processing algorithms on consumer level graphics hardware.

I spent my summer of 2002 working at Nvidia in Santa Clara California where I worked on their architecture team that designs the new up and coming graphics processors. During my time there I designed new features for future products while assessing Nvidia's existing product line with that of their competitor's.

I have spent two summers interning at Intel at their Intel Architecture Labs in their 3D software technologies group, which is intended to be an "Idea Factory", research oriented branch of Intel. In the summer of 2000, I worked closely with Intel's software graphics team. The team at that time was developing the 3D authoring capabilities of Macromedia (now Adobe) Director 8.5 Shockwave Studio. Much of my work focused on developing real-time simulation techniques for cloth animation. In the summer of 1999 I worked on developing Intel's IPEAK graphics performance toolkit product with assisted developers in performance tuning, optimizing, and profiling OpenGL applications.
