NVIDIA's real-time path tracing library and sample application, a pure path tracer built on the Donut framework with DirectX 12 and Vulkan backends. It serves as a reference implementation for integrating real-time ray-traced light transport with techniques like NEE-AT guided importance sampling and DLSS-RR denoising.

Use cases

• integrate real-time path tracing into a game engine
• learn how to build a real-time path tracer
• reference implementation for DXR and Vulkan ray tracing
• experiment with neural denoising like DLSS-RR
• benchmark GPU path tracing performance
• study importance sampling and light transport techniques

When to choose

• you need a production-quality reference path tracer for DirectX 12 or Vulkan
• you want to learn modern real-time ray tracing techniques from NVIDIA
• you're building a renderer and want a clean starting point for path tracing integration

When to avoid

• you need a rasterization-based renderer
• you target hardware without DXR/Vulkan ray tracing support
• you need a full game engine rather than a rendering sample
