Hello. I am interested in ray-tracing, and GPGPU. I plan to work on OpenCL acceleration of the BRL-CAD librt rendering pipeline:

Development Status

  • Refactored dispatcher, shoot, optical renderer to process many rays in parallel when rendering an image or block.
  • HLBVH object partitioning builder in C. traversal in OCL.
  • GPU side database storage of OCL implemented primitives.
  • Ported compute intensive or critical parts of the dispatcher, boolean evaluation, optical renderer to OCL.
  • OCL dispatcher that performs the shot routines for a whole frame.
  • OCL rasterizer that does the pixel pushing for a whole frame.
  • OCL lighting modes: Phong, Diffuse, Surface Normals.
  • OCL lighting modes: Multi-hit transparent.
  • TOR and TGC shot routines in OCL.||#393||TRUNK
  • Surface normal routines for all OCL implemented primitives.
  • CPU HLBVH BOT shot construction with OCL traversal and interpolated per pixel normals.
