Ground truth lighting in real time.
Whether you’re rasterizing, tracing rays, or both, this SDK provides the tools and sample code to build an interactive physically-accurate reference renderer to aid in your development, ensuring your lighting during production is true to life.
Highly customizable toolkit.
This SDK gives you the flexibility to take individual components that suit your needs or take the entire path tracer and integrate it directly into your game engine.
Ultra-realism mode for your game.
This path tracer leverages new hardware in NVIDIA GeForce RTX® 40 Series GPUs, allowing you to provide the highest-quality rendering modes with uncompromised performance.
