Detailed Description

Tachyon ray tracing host side routines and internal APIs that provide the core ray OptiX-based RTX-accelerated tracing engine.

The major responsibilities of the core engine are to manage runtime RT pipeline construction and JIT-linked shaders to build complete ray tracing pipelines, management of RT engine state, and managing associated GPU hardware. Written for NVIDIA OptiX 7 and later.

The declarations and prototypes needed to drive the raytracer. Third party driver code should only use the functions in this header file to interface with the rendering engine.
