From BRL-CAD
Reports
Week 4
- Discovered that the crashing was due to multi-threaded issues. I'm currently using -P 1 on my tests.
- Re-defined the OSLRenderer interface, so that it considers recursion rays needed for reflection and transmission
- Start studying how the rt application works.
Week 3
- Adapted the OSL raytracer so that it can be called by the osl shader.
- The rt application is currently crashing. Inspecting with valgrind I suspect that it is due to memory leaks.
Week 2
- Not very productive week. With the help of the mentors I managed to solve the compile error.
Week 1
- Implemented a (poor) polka dot for BRL-CAD, to get familiarized with the shaders syntax. [polka dot goblet]
- 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)
- Compiled OSL sources both in Ubuntu 10.10 and Mac OS X Snow Leopard. (had trouble with 11.04, mainly due to LLVM)
- Found a raytracer developed by Erich Ocean and Brecht [1] that uses OSL-written shaders. It currently renders refraction wrongly. [screenshot]
- Discovered the cause of the above error: I was using the wrong shader for glass. Now, the image is correctly rendered. [screenshot]
