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.
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 or B series, or Nvidia GeForce 20 , 30 , or 40 series video card , which is designed to handle the high computing load used for ray tracing.
It employs geometric ray tracing, a technique for modeling the propagation of light through an optical system by assuming that wavelength of light is much smaller than the components in the system and thus that the light can be treated as pencil-thin rays. Ansys Zemax OpticStudio can perform sequential and non-sequential ray tracing.

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.
The ray tracing algorithm is inherently suitable for scaling by parallelization of individual ray renders. [3] However, anything other than ray casting requires recursion of the ray tracing algorithm (and random access to the scene graph ) to complete their analysis, [ 4 ] since reflected, refracted, and scattered rays require that various ...
[11] One of POV-Ray's main attractions is its large collection of third-party-made assets and tools. A large number of tools, textures, models, scenes, and tutorials can be found on the web. It is also a useful reference for those wanting to learn how ray tracing and related 3D geometry and computer graphics algorithms work.
OptiX works by using user-supplied instructions (in the form of CUDA kernels) regarding what a ray should do in particular circumstances to simulate a complete tracing process. [4] A light ray (or perhaps another kind of ray) might have a different behavior when hitting a particular surface rather than another one, OptiX allows to customize ...
