From February to July, 2003, I had the opportunity to work in the Dept. of Computer Science, University of Bristol, United Kingdom, as a Visiting Fellow under the supervision of Dr. Alan Chalmers.

My work concentrated on developing a parallel MPI-based version of Radiance, that will be used as a basis to produce an interactive high fidelity navigator in virtual worlds using the RADIANCE global illumination model. I performed a few studies on parallelism overheads and scalability issues, particularly concerning the irradiance cache. Details can be found on the Technical Report.

Below I added links to a few animations produced using the parallel Radiance, in high, low and adaptive quality. The model of the Kalabsha Temple is particularly interesting. It was developped by Veronica Sundstedt, Patrick Ledda and Alan Chalmers from Bristol.
