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. | BRL-CAD has one of the oldest and fastest parallel ray tracing implementations around but we don't currently leverage the GPU.

| − | 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. Your objective is to implement at least two more while evaluating how your conversion compares to the non-GPGPU implementation. | + | 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 arbitrary polyhedron, 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. |
