Detailed Description

Tachyon ray tracing engine core routines and data structures compiled to PTX for runtime JIT to build complete ray tracing pipelines.

Key data structures defined here are shared both by the compiled PTX core ray tracing routines, and by the host code that assembles the complete ray tracing pipeline and launches the pipeline kernels. Written for NVIDIA OptiX 7 and later.
