DXR was released with the Windows 10 October update (version 1809) on October 10, 2018. It requires an AMD Radeon RX 6000 series , AMD Radeon RX 7000 series , Intel Arc A series, or Nvidia GeForce 20 , 30 , or 40 series video card , which is designed to handle the high computing load used for ray tracing.
Nvidia OptiX (OptiX Application Acceleration Engine) is a ray tracing API that was first developed around 2009. [1] The computations are offloaded to the GPUs through either the low-level or the high-level API introduced with CUDA. CUDA is only available for Nvidia's graphics products. Nvidia OptiX is part of Nvidia GameWorks. OptiX is a high ...
Ray tracing is a technique that can generate near photo-realistic computer images. A wide range of free software and commercial software is available for producing these images. This article lists notable ray-tracing software.
Nvidia RTX (also known as Nvidia GeForce RTX under the GeForce brand) is a professional visual computing platform created by Nvidia, primarily used in workstations for designing complex large-scale models in architecture and product design, scientific visualization, energy exploration, and film and video production, as well as being used in mainstream PCs for gaming.
Real-time hardware accelerated ray tracing is a new feature for RDNA 2 which is handled by a dedicated ray accelerator inside each CU. [10] Ray tracing on RDNA 2 relies on the more open DirectX Raytracing protocol rather than the Nvidia RTX protocol.
This recursive ray tracing of reflective colored spheres on a white surface demonstrates the effects of shallow depth of field, "area" light sources, and diffuse interreflection. (c. 2008) In 3D computer graphics, ray tracing is a technique for modeling light transport for use in a wide variety of rendering algorithms for generating digital images.
In August 2019, Nvidia announced Minecraft RTX, an official Nvidia-developed patch for the game Minecraft adding real-time DXR ray tracing exclusively to the Windows 10 version of the game. The whole game is, in Nvidia's words, "refit" with path tracing , which dramatically affects the way light, reflections, and shadows work inside the engine.
Additional features confirmed by AMD include real-time, hardware accelerated ray tracing, "Infinity Cache", mesh shaders, sampler feedback and variable rate shading. [26] [10] The company announced that RDNA 2 would be used in next-generation gaming consoles and PC graphics cards [26] code-named "Navi 2X" and also nicknamed as "Big Navi". [26]
