Q&A: Real-Time Ray Tracing in a Cinematic Scene

Nvidia

Six years ago, real-time ray tracing was seen as a pipe dream. Back then, cinematic-quality rendering required computer farms to slowly bake every frame. Six years ago, real-time ray tracing was seen as a pipe dream. What is the difference between path tracing and ray tracing?

NVIDIA Research: Learning and Rendering Dynamic Global Illumination with One Tiny Neural Network in Real-Time

Nvidia

Today, NVIDIA is releasing a SIGGRAPH 2021 technical paper, “ Real-time Neural Radiance Caching for Path Tracing ” that introduces another leap forward in real-time global illumination: Neural Radiance Caching. Before NVIDIA RTX introduced real-time ray tracing to games, global illumination in games was largely static.
