BRL-CAD's shader system is custom developed for the librt raytracer. Shaders are currently coded in C and explicitly added to the active shader list. A question of interest is whether we can utilize work being done for other open source raytracing shader systems to improve the flexibility of BRL-CAD's shader system and take advantage of shaders developed for other systems.

A proposal should outline what changes are proposed to BRL-CAD's current shaders. Initial stages would involve either writing the shader bridge in liboptical or designing a new approach (remember though, all existing shader functionality in the current system must be preserved, even if it is re-implemented in some fashion. Be careful about biting off more than you can achieve in a summer.)

References

This task will require a fair bit of background research in order to put together a compelling proposal - interested students should study BRL-CAD's shader system to determine how it works, and then look at other open source, license compatible systems to see what they may offer. Candidates include:

Code of relevance:

  • src/liboptical
  • include/optical.h

Requirements

  • Familiarity with C/C++
