The update encompasses several new technologies:

Neural Radiance Cache (NRC): This feature employs advanced ray tracing techniques to accelerate the rendering process. By utilizing artificial intelligence, NRC dynamically trains a cache in real time, enhancing performance and achieving more precise global illumination effects. The NRC library is currently in experimental phase.

Spatial Hash Radiance Cache (SHARC): SHARC utilizes spatial hashing data structures to provide a flexible and efficient solution for path tracing. Unlike NRC, SHARC does not rely on AI or neural networks and is directly integrated with GPU ray tracing capabilities in DirectX or Vulkan environments. The technology significantly improves global illumination accuracy without compromising performance.

Dynamic Diffuse Global Illumination (DDGI): DDGI facilitates real-time global illumination in path tracing, enabling multiple indirect light bounces without the need for pre-computed lighting solutions. This technology adds a new layer of realism to rendered scenes by dynamically adjusting to changes in lighting conditions.

The RTX Global Illumination 2.0 SDK represents NVIDIA's commitment to advancing graphics technology, offering developers the tools to create more immersive and realistic environments in their applications.
