Reducing Acceleration Structure Memory with NVIDIA RTXMU
Acceleration structures spatially organize geometry to accelerate ray tracing traversal performance. When you create an acceleration structure, a conservative...
In ray tracing, more geometries can reside in the GPU memory than with the rasterization approach because rays may hit the geometries out of the view frustum....
Managing Memory for Acceleration Structures in DirectX Raytracing
In Microsoft Direct3D, anything that uses memory is considered a resource: textures, vertex buffers, index buffers, render targets, constant buffers,...
Optimizing real-time graphics applications for maximum performance can be a challenging endeavor, and ray tracing is no exception. Whether you want to make...
Optimizing VK/VKR and DX12/DXR Applications Using Nsight Graphics: GPU Trace Advanced Mode Metrics
Many GPU performance analysis tools are based on a capture and replay mechanism, where a frame is first captured (either in-memory or to disk), and then...
This post was revised March 2020 to reflect newly added support in DXC for targeting the SPV_KHR_ray_tracing multi-vendor extension. Vulkan logo DirectX Ray...
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...
This post presents best practices for implementing ray tracing in games and other real-time graphics applications. We present these as briefly as possible to...
Parallel Shader Compilation for Ray Tracing Pipeline States
In ray tracing, a single pipeline state object (PSO) can contain any number of shaders. This number can grow large, depending on scene content and ray types...
Effectively Integrating RTX Ray Tracing into a Real-Time Rendering Engine
RTX is NVIDIA's new platform for hybrid rendering, allowing the combination of rasterization and compute-based techniques with hardware-accelerated ray tracing...
Video Series: Practical Real-Time Ray Tracing With RTX
RTX introduces an exciting and fundamental shift in the way lighting systems work in games and applications. In this video series, NVIDIA Engineers Martin-Karl...
Editor’s note: What happens when a veteran graphics programmer with substantial experience in old-school ray tracing (in other words, offline rendering), gets...
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...
After decades of research, NVIDIA has unearthed the holy grail of video game graphics: real-time ray tracing! This series of videos will explain why you need...
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...
