NVIDIA Path Tracing SDK v1.0.0

[JeGX]

Path Tracing SDK is a code sample that strives to embody years of ray tracing and neural graphics research and experience. It is intended as a starting point for a path tracer integration, as a reference for various integrated SDKs, and/or for learning and experimentation.

Features
- DirectX 12 and Vulkan back-ends
- Reference and real-time modes
- Simple BSDF model that is easy to extend
- Simple asset pipeline based on glTF 2.0 (support for a subset of glTF extensions including animation)
- NEE/visibility rays and importance sampling for environment maps with MIS
- Basic volumes and nested dielectrics with priority
- RayCone for texture MIP selection
- Basic analytic lights (directional, spot, point)
- RTXDI integration for ReSTIR DI (light importance sampling) and and ReSTIR GI (indirect lighting)
- OMM integration for fast ray traced alpha testing
- NRD ReLAX and ReBLUR denoiser integration with up to 3-layer path space decomposition (Stable Planes)
- Reference mode 'photo-mode screenshot' with basic OptiX denoiser integration
- Basic TAA, tone mapping, etc.
- Streamline + DLSS integration (coming very soon)
