  2. Ray tracing (graphics) - Wikipedia

    en.wikipedia.org/wiki/Ray_tracing_(graphics)

    The closest surface intersected by the ray was the visible one. This non-recursive ray tracing-based rendering algorithm is today called "ray casting". His algorithm then traced secondary rays to the light source from each point being shaded to determine whether the point was in shadow or not.

  3. List of ray tracing software - Wikipedia

    en.wikipedia.org/wiki/List_of_ray_tracing_software

    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.

  4. Ray-tracing hardware - Wikipedia

    en.wikipedia.org/wiki/Ray-tracing_hardware

    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 ...

  5. Rendering (computer graphics) - Wikipedia

    en.wikipedia.org/wiki/Rendering_(computer_graphics)

    Ray tracing was often used for rendering reflections in animated films, until path tracing became standard for film rendering. Films such as Shrek 2 and Monsters University also used distribution ray tracing or path tracing to precompute indirect illumination for a scene or frame prior to rendering it using rasterization. [49]: 118–121

  6. DirectX Raytracing - Wikipedia

    en.wikipedia.org/wiki/DirectX_Raytracing

    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.

  7. POV-Ray - Wikipedia

    en.wikipedia.org/wiki/POV-Ray

    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.

  8. Spectral rendering - Wikipedia

    en.wikipedia.org/wiki/Spectral_rendering

    Spectral rendering is often used in ray tracing or photon mapping to more accurately simulate the scene, often for comparison with an actual photograph to test the rendering algorithm (as in a Cornell Box) or to simulate different portions of the electromagnetic spectrum for the purpose of scientific work.

  9. OptiX - Wikipedia

    en.wikipedia.org/wiki/OptiX

    In order to render a complex scene or trace different paths for any ray OptiX takes advantage of GPGPU computing by exploiting Nvidia CUDA platform. Since the process of shooting rays and setting their behavior is highly customizable, OptiX may be used in a variety of other applications aside from ray tracing.
