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.
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.
3Delight is a 3D computer graphics software that runs on Microsoft Windows, macOS (both Intel and Apple Silicon) and Linux (both x86 and Graviton).Developed by Illumination Research, it is both a photorealistic and NPR path tracing offline renderer based on its NSI API scene description and on Open_Shading_Language for shading.
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.
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 ...
Rayshade is a software application for ray tracing (3D rendering) from a text 3D model description input file into a finished, realistic image. The first version was written between 1987 and 1988 at Princeton University. It is written by Craig E. Kolb in C, yacc, and lex.
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 Persistence of Vision Ray Tracer, most commonly acronymed as POV-Ray, is a cross-platform ray-tracing program that generates images from a text-based scene description. It was originally based on DKBTrace, written by David Kirk Buck and Aaron A. Collins for Amiga computers.
