Reports

Week 3

  1. Adapted the OSL raytracer so that it can be called by the osl shader.
  2. The rt application is currently crashing. Inspecting with valgrind I suspect that it is due to memory leaks.

Week 2

  1. Not very productive week. With the help of the mentors I managed to solve the compile error.

Week 1

  1. Implemented a (poor) polka dot for BRL-CAD, to get familiarized with the shaders syntax. [polka dot goblet]
  2. Trying to compile the OSL raytracer outside OSL build, but getting compile errors, that I have no idea on how to solve. I've emailed the dev list asking for help.

Week 0 (Community Bonding)

  1. Compiled OSL sources both in Ubuntu 10.10 and Mac OS X Snow Leopard. (had trouble with 11.04, mainly due to LLVM)
  2. Found a raytracer developed by Erich Ocean and Brecht [1] that uses OSL-written shaders. It currently renders refraction wrongly. [screenshot]
  3. Discovered the cause of the above error: I was using the wrong shader for glass. Now, the image is correctly rendered. [screenshot]
