WebNov 20, 2024 · DirectX Ray Tracing, Vulkan’s NV Ray Tracing extension, and OptiX (or collectively, the RTX APIs) build on the same execution model for running user code to trace and process rays. The user creates a Shader Binding Table (SBT), which consists of a set of shader function handles and embedded parameters for these functions. WebNov 8, 2024 · NVIDIA OptiX 7.4 has increased the size of the ray payload from 8 to 32 registers. The payload registers are the mechanism NVIDIA OptiX offers for passing arbitrary data along with a ray, from the caller …
