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 handled with the PSO; construction cost of the state object can significantly increase. The DXR API makes it possible to distribute part of the creation work to multiple … Continued
In the realm of computer graphics, achieving photorealistic visuals has been a long-sought goal. NVIDIA OptiX is a powerful and flexible ray-tracing framework, enabling you to harness the potential of ray tracing. NVIDIA OptiX is a GPU-accelerated, ray-casting API based on the CUDA parallel programming model. It gives you all the tools required to implement … Continued
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
RTX is NVIDIA’s new platform for hybrid rendering, allowing the combination of rasterization and compute-based techniques with hardware-accelerated ray tracing and deep learning. It has already been adopted in a number of games and engines. Based on those experiences, this blog aims to give the reader an insight into how RTX ray tracing is best … Continued
In the fourth installment of our ‘Ray Tracing Essentials’ video series, NVIDIA’s Eric Haines runs through the ray tracing pipeline, including the five types of ray tracing shaders, and how they fit together.
In the third installment of our ‘Ray Tracing Essentials’ video series, NVIDIA’s Eric Haines touches on the decades-long history of ray tracing hardware and explains modern acceleration techniques.
Because ray tracing’s operations closely simulate the way light propagates through a scene, it can be used to produce a wide range of effects.
Epic Games announced the release of Unreal Engine 4.22. This update introduces early access support for a Real-Time Ray Tracer and a Path Tracer, optimized for DXR (DirectX Raytracing) and NVIDIA RTX series GPUs.
Recent announcements of NVIDIA’s new Turing GPUs, RTX technology, and Microsoft’s DirectX Ray Tracing have spurred a renewed interest in ray tracing. Using these technologies vastly simplifies the ability to write applications using ray tracing. But what if you’re curious about how ray tracing actually works? One way to learn is to code your own ray tracing … Continued
Scientists from the Wisconsin IceCube Particle Astrophysics Center are using ray tracing on NVIDIA GPUs to accelerate simulations of subatomic particles by hundreds of times.
“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
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 overnight—a painstaking process. By 2018, this level of performance was achievable in real-time, at 45 frames per second, enabling applications like video games to take a massive leap in graphical quality. … Continued
This post gathers best practices based on our experiences so far on using NVIDIA RTX ray tracing in games.
We recently caught up with the Substance team about ray tracing integration in Substance.
With real-time ray tracing, artists and designers can create cinematic-quality graphics faster than before. And now you have a chance to show us what you can design with RTX.
