OpenCL GPGPU Raytracing
Contact "brlcad" on irc.freenode.net
BRL-CAD has one of the oldest and fastest parallel ray tracing implementations around but we don't currently leverage the GPU. With implicit geometry and constructive solid geometry (CSG) Boolean operations, we also have a very different approach to ray tracing that has its own set of academic challenges.
Your project is to help us introduce a GPGPU pipeline into BRL-CAD using OpenCL. You're welcome to use a library that encapsulates OpenCL. We have a dozen primitives in BRL-CAD that need to be converted to OpenCL. One of them which is done is an ellipsoid (a quadric primitive), so you have an example to follow. Your objective is to implement at least two more while evaluating how your conversion compares to the non-GPGPU implementation.
These quadric primitives still need to be converted: elliptical hyperboloid, superquadratic ellipsoid, and heart.
These primitives are not quadrics but they should also be relatively straightforward to convert: polyhedron with an arbitrary number of faces (use arbitrary polyhedron as an example), and FASTGEN4 CLINE.
Languages: C and OpenCL (or other GPGPU API)
