    en.wikipedia.org/wiki/List_of_common_3D_test_models

    This is a list of models and meshes commonly used in 3D computer graphics for testing and demonstrating rendering algorithms and visual effects. Their use is important for comparing results, similar to the way standard test images are used in image processing.

  3. Foreground detection - Wikipedia

    en.wikipedia.org/wiki/Foreground_detection

    For calculating the image containing only the background, a series of preceding images are averaged. For calculating the background image at the instant t: (,,) = = (,,) where N is the number of preceding images taken for averaging. This averaging refers to averaging corresponding pixels in the given images.

  4. Level of detail (computer graphics) - Wikipedia

    en.wikipedia.org/wiki/Level_of_detail_(computer...

    [1] [2] [3] LOD can be decreased as the model moves away from the viewer or according to other metrics such as object importance, viewpoint-relative speed or position. LOD techniques increase the efficiency of rendering by decreasing the workload on graphics pipeline stages, usually vertex transformations. The reduced visual quality of the ...

  5. Ray tracing (graphics) - Wikipedia

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

    The LINKS-1 system was developed to realize an image rendering methodology in which each pixel could be parallel processed independently using ray tracing. By developing a new software methodology specifically for high-speed image rendering, LINKS-1 was able to rapidly render highly realistic images."

  6. Path tracing - Wikipedia

    en.wikipedia.org/wiki/Path_tracing

    Path tracing is a computer graphics Monte Carlo method of rendering images of three-dimensional scenes such that the global illumination is faithful to reality. Fundamentally, the algorithm is integrating over all the illuminance arriving to a single point on the surface of an object.

  7. Ray casting - Wikipedia

    en.wikipedia.org/wiki/Ray_casting

    Ray-cast image of idealized universal joint with shadow. Ray casting is the methodological basis for 3D CAD/CAM solid modeling and image rendering. It is essentially the same as ray tracing for computer graphics where virtual light rays are "cast" or "traced" on their path from the focal point of a camera through each pixel in the camera sensor to determine what is visible along the ray in the ...

  8. Z-buffering - Wikipedia

    en.wikipedia.org/wiki/Z-buffering

    In rendering, z-culling is early pixel elimination based on depth, a method that provides an increase in performance when rendering of hidden surfaces is costly. It is a direct consequence of z-buffering, where the depth of each pixel candidate is compared to the depth of the existing geometry behind which it might be hidden.

  9. LuxCoreRender - Wikipedia

    en.wikipedia.org/wiki/LuxCoreRender

    Displacement mapping and subdivision: Based on procedural or image textures, object surfaces can be transformed. Network and co-operative rendering: Rendering time can be reduced by combining the processing power of multiple computers. IPv6 is also supported. Perspective (including shift lens), orthographic and environment cameras.
