New HLSL shaders, ray-generation, closest-hit, any hit, and miss, that are used describe computationally what DXR is doing when rendering raytracing. These shaders utilize the TraceRay function in HLSL to trace rays in the environment. When the ray interacts with the generated plane it can call on one of many selected hit or miss shaders.
HLSL programs come in six forms: pixel shaders (fragment in GLSL), vertex shaders, geometry shaders, compute shaders, tessellation shaders (Hull and Domain shaders), and ray tracing shaders (Ray Generation Shaders, Intersection Shaders, Any Hit/Closest Hit/Miss Shaders). A vertex shader is executed for each vertex that is submitted by the ...
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 ...
English: A 3D rendered image using ray tracing, radiosity and photon mapping, rendered by the POV-Ray program. The smoothness of the meshes used for the cows has been increased using subdivision. The scene uses very simple lighting, and uniform background colors, to make it easier to interpret differences in global illumination.
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 computer graphics, the slab method is an algorithm used to solve the ray-box intersection problem in case of an axis-aligned bounding box (AABB), i.e. to determine the intersection points between a ray and the box. Due to its efficient nature, that can allow for a branch-free implementation, it is widely used in computer graphics ...

The Wine compatibility layer, a free software reimplementation of several Windows APIs, includes an implementation of Direct3D. Direct3D's main competitor is Khronos' OpenGL and its follow-on Vulkan. Fahrenheit was an attempt by Microsoft and SGI to unify OpenGL and Direct3D in the 1990s, but was eventually canceled.
