Hello. I am interested in ray-tracing, and GPGPU. I work on the OpenCL acceleration of the BRL-CAD librt rendering pipeline:
OCL librt TODO
- Split
struct hitin common.cl into two structs. One forshot()results and another fornorm()results. This will reduce the amount of memory used to store temporary results between stages. - Spatial partitioning (perhaps a hybrid Kd-tree) in order to have early exit on scenes with high depth complexity.
- Quadric Primitives: HYP, SUPERELL.
- Grid Primitives: DSP, EBM, VOL.
- Composite Primitives: EXTRUDE, REVOLVE, PIPE, METABALL.
- Instancing Primitive: SUBMODEL.
- Make Phong shader results look 100% similar to ANSI C librt.
- BOT plate mode.
- FASTGEN support (both CLINE primitive and bool.cl code).
OCL librt 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 (Single Stage Render Pipeline only).
- ARB8, EHY, ELL, EPA, ETO, PART, REC, RHC, RPC, SPH, TGC, TOR shot routines in OCL.
- Surface normal routines for all OCL implemented primitives.
- CPU HLBVH BOT shot construction with OCL traversal and interpolated per pixel normals.
