A comprehensive list of free and commercial software for producing ray-traced images. Compare the features, licenses, platforms and availability of various ray-tracing software products.
Ray tracing is a technique for modeling light transport in 3D computer graphics. It can simulate various optical effects, such as reflection, refraction, shadows, and sound waves, but requires more computational cost and time than scanline rendering methods.
A Stingray is a cellular phone surveillance device that mimics a wireless carrier cell tower to intercept communications data or metadata from nearby devices. Learn about its technology, active and passive modes, and legal issues in different countries.
DirectX Raytracing (DXR) is a feature of DirectX 12 that implements ray tracing, a technique for realistic graphics rendering. Learn about the features, technical details, and updates of DXR, and see examples of raytraced scenes.
Ray tracing of a beam of light passing through a medium with changing refractive index.The ray is advanced by a small amount, and then the direction is re-calculated. Ray tracing works by assuming that the particle or wave can be modeled as a large number of very narrow beams (), and that there exists some distance, possibly very small, over which such a ray is locally straight.
Learn about the special-purpose computer hardware designed for accelerating ray tracing calculations, from early experiments to modern GPUs. Compare different approaches, features, and performance of ray tracing hardware across various products and platforms.
Tachyon is a parallel/multiprocessor ray tracing software. It is a parallel ray tracing library for use on distributed memory parallel computers, shared memory computers, and clusters of workstations. Tachyon implements rendering features such as ambient occlusion lighting, depth-of-field focal blur, shadows, reflections, and others.
Photopia Optical Design Software (Photopia) is a commercial optical engineering ray-tracing software program for the design and analysis of non-imaging optical systems. . Photopia is written and distributed by LTI Optics, LLC (formerly Lighting Technologies, Inc.) and was first released i
