Coffee Break Series: Ray Tracing in Games with NVIDIA RTX

Ray tracing will soon revolutionize the way video games look. Ray tracing simulates how rays of light hit and bounce off of objects, enabling developers to create stunning imagery that lives up to the word “photorealistic”. Ignacio Llamas and Edward Liu from NVIDIA’s real-time rendering software team will introduce you to real-time ray tracing in … Continued

Introduction to NVIDIA RTX and DirectX Ray Tracing

“Ray tracing is the future, and it always will be!” has been the tongue-in-cheek phrase used by graphics developers for decades when asked whether real-time ray tracing will ever be feasible. Everyone seems to agree on the first part: ray tracing is the future. That’s because ray tracing is the only technology we know of … Continued

Ray Tracing Magic From a One-Person Team

Abstraction, the winner of the DXR Spotlight Contest 2020, takes its audience on a tour of a world that tricks the eye and startles the senses. We sat down with the creator of Abstraction, Jonah Walters, to learn how he built it all by himself.

Video Series: Real-Time Ray Tracing for Interactive Global Illumination Workflows in Frostbite

Real-time ray tracing is upon us. Electronic Arts leads the charge in integrating the technology on an engine level. This video series features Sebastien Hillaire, Senior Rendering Engineer at EA/Frostbite. Sebastian discusses real-time raytracing and global illumination (GI) workflows in Frostbite. He explains the context and the current workflows Frostbite uses, then describes the process … Continued

RTX Coffee Break: Ray Tracing and Denoising (9:52 minutes)

Ray tracing can lead to very noisy images without the right tools. In this video, we explain the challenges of developing a real-time denoising solution, and describe the results NVIDIA has achieved using RTX.   Five Things to Remember: The realistic budget is 1-2 samples per pixel (which is insufficient to get anything reliable) with … Continued

Introduction to Ray Tracing in Unreal Engine 4.22

Epic Games is adding ‘Early Access’ support for ray tracing through the DirectX Raytracing API (DXR) to Unreal Engine with the pending release of Unreal Engine 4.22. Demos dating back to GDC 2018 show impressive ray tracing results using DXR. However, UE 4.22 integrates ray tracing support into the mainline branch, making ray tracing available to … Continued

NVIDIA OptiX Ray Tracing Powered by RTX

Ray Tracing vs Rasterization Conventional 3D rendering has typically used a process called rasterization since the 1990s. Rasterization uses objects created from a mesh of triangles or polygons to represent a 3D model of an object. The rendering pipeline then converts each triangle of the 3D models into pixels on a 2D image plane. These … Continued
