NVIDIA researchers will present their paper “Neural Scene Graph Rendering” at SIGGRAPH 2021, August 9-13, which introduces a neural scene representation inspired by traditional graphics scene graphs. Recent advances in neural rendering have pushed the boundaries of photorealistic rendering; take StyleGAN as an example of producing realistic images of fictional people. The next big challenge…
]]>NVIDIA researchers will present their paper “An Unbiased Ray-Marching Transmittance Estimator” at SIGGRAPH 2021, August 9-13, showing a new way to compute visibility in scenes with complex volumetric effects. When Monte Carlo sampling is used to compute lighting effects such as soft shadows and global illumination, shadow rays are used to query the visibility between lights and…
]]>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. Global illumination, that is, illumination due to light bouncing around in a scene, is essential for rich, realistic visuals. This is a challenging task, even in cinematic rendering…
]]>The recent unveiling of Quake 2 RTX was a watershed moment for real-time computer graphics: it is the first fully path-traced game. Path tracing is an advanced rendering technique that uses ray tracing to simulate the physics of light in a scene. Quake 2 RTX shows off path tracing’s benefits, with complex lighting from hundreds of lights bringing breath-taking beauty to the twenty-one-year-old…
