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 help you quickly find key ideas. This is based on a presentation made at the 2019 GDC by NVIDIA engineers. Main Points Optimize your acceleration structure (BLAS/TLAS) build/update to take at most 2ms via pruning and selective updates Denoisi
The NVIDIA Asteroids demo showcases how the mesh shading technology built into NVIDIA’s Turing GPU architecture can dramatically improve performance and image quality when rendering a substantial number of very complex objects in a scene. The following video highlights the capabilities of the mesh shader in the Asteroids demo. This video shows off the Asteroids demo in action. Turing introduces a
Turing GPUs introduce a new shading capability called Texture Space Shading (TSS), where shading values are dynamically computed and stored in a texture as texels in a texture space. Later, pixels are texture mapped, where pixels in screen-space are mapped into texture space, and the corresponding texels are sampled and filtered using a standard texture lookup operation. With this technology we ca
The Turing architecture introduces a new programmable geometric shading pipeline through the use of mesh shaders. The new shaders bring the compute programming model to the graphics pipeline as threads are used cooperatively to generate compact meshes (meshlets) directly on the chip for consumption by the rasterizer. Applications and games dealing with high-geometric complexity benefit from the fl

Virtual Reality Virtual reality is the next frontier of gaming and 3D intensive applications, and NVIDIA is helping to pave the way with VRWorks. VRWorks is NVIDIA’s set of APIs, libraries, and features that enable both VR headset and game developers to deliver amazin
With a wide range of shaders including skin, natural effects, metals, post processing effects, and much more, the NVIDIA Shader Library exists to help developers easily find and integrate great shaders into their projects. All the shaders in this library are provided free of charge for use in derivative works, whether academic, commercial, or personal (Full License). If you would like to submit a
The Cg Toolkit is a legacy NVIDIA toolkit no longer under active development or support. Cg 3.1 is our last release and while we continue to make it available to developers, we do not recommend using it in new development projects because future hardware features may not be supported. NVIDIA was proud to introduce programmable shading with Cg, which supported dozens of different OpenGL and DirectX
