RTX Direct Illumination (RTXDI) RTXDI offers realistic lighting of dynamic scenes that require computing shadows from millions of area lights. Until now, this has not been possible in video games. Traditionally, game developers have baked most lighting and supported a small number of “hero” lights that are computed at runtime. With RTXDI, lighting artists can render scenes with millions of dynamic area lights in real-time without complex computational overheads or disruptive changes to the artist’s workflow.

NVIDIA Marbles at Night RTX is a fully playable physics-based game. It is entirely ray traced with NVIDIA DLSS integrated.

It is powered by NVIDIA's Omniverse and showcases photorealistic real-time graphics.

This playable demo has hundreds of dynamic ray-traced lights and over one hundred million polygons, running smoothly at 1440p on a single GeForce RTX 3090.

NVIDIA and Dartmouth College researchers collaborated to create an ACM SIGGRAPH 2020 paper showing how to render dynamic direct lighting and shadows from millions of area lights in real-time. This was previously impossible. This video shows real-time rendering of scenes with many dynamic lights, and all lighting and shadowing are computed using the ReSTIR algorithm described in the paper, plus a denoising algorithm.
