DirectX Raytracing (DXR) is a feature introduced in Microsoft's DirectX 12 that implements ray tracing, for video graphic rendering. DXR was released with the Windows 10 October update (version 1809) on October 10, 2018.
In Direct3D 11, the concept of feature levels has been further expanded to run on most downlevel hardware including Direct3D 9 cards with WDDM drivers.. There are seven feature levels provided by D3D_FEATURE_LEVEL structure; levels 9_1, 9_2 and 9_3 (collectively known as Direct3D 10 Level 9) re-encapsulate various features of popular Direct3D 9 cards conforming to Shader Model 2.0, while ...
Various implementations of ray tracing hardware have been created, both experimental and commercial: (1995) Advanced Rendering Technology (ART) founded [6] in Cambridge, UK, based on a 1994 PhD thesis, to produce dedicated ray tracing silicon (initially the "AR250" chip, which accelerated ray-triangle intersection, bounding box traversal and shading), using a "RenderDrive" networked ...
Direct3D 12 version 2004 – Windows 10 May 2020 Update (version 2004) brings support for DirectX 12 Ultimate, Mesh & Amplification Shaders, [137] Sampler Feedback, [138] as well DirectX Raytracing Tier 1.1 [139] and memory allocation improvements.
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 March 2018, DirectX Raytracing (DXR) was announced, capable of real-time ray-tracing on supported hardware, [65] and the DXR API was added in the Windows 10 October 2018 update. In 2019 Microsoft announced the arrival of DirectX 12 to Windows 7 but only as a plug-in for certain game titles.
Ray tracing solves this problem by reversing the process, instead sending view rays from the observer and calculating how they interact until they reach a light source. [24] Although this way more effectively uses processing time and produces a light simulation closely imitating natural lighting, ray tracing still has high computation costs due ...
