For direct illumination, the integral devolves into a sum over all lights. Realistic rendering requires solving the rendering equation one time per pixel, integrating the incident light to determine how much reflects toward your camera. You can easily add light primitives not supported by RTXDI by providing an appropriate sampling function for the new primitive. An existing G-buffer containing data needed for evaluation of materials and lighting for any combination of lights and screen pixels.Īny emissive surface provided to RTXDI automatically illuminates its surroundings.Emissive meshes and primitive lights (spheres, rectangles, and so on) are enumerated and provided to RTXDI.Emissive surfaces have material properties including an easily evaluated emissive power.RTXDI should integrate easily with existing assets and pipelines. Initial releases build on recently published research on reservoir-based spatiotemporal importance resampling (ReSTIR), including a variety of improvements dramatically increasing robustness and performance. Long-term, RTXDI is a collection of the best research and development efforts enabling this flexible and powerful application of ray tracing. Runs on any GPU with hardware accelerated ray tracing capability.

Moves all lights dynamically and interacts with dynamic geometry.The key features of RTXDI include the following: Performance is largely decoupled from lighting complexity, so RTXDI seamlessly scales from one light to millions. To enable a light, add emissivity to a surface’s material properties. All lights in a scene can dynamically move, turn on and off, change color, and cast correct shadows and lighting.

With RTXDI, the artist’s imagination need not be gated on light complexity or shadow map costs. RTXDI uses the power of ray tracing to remove artistic constraints common in traditional rasterization pipelines. An early RTXDI prototype renders San Miguel, a 10 million triangle scene with 11,000 emissive triangles and environment mapped sun and sky lighting in under 8 ms.
