  2. Path tracing - Wikipedia

    en.wikipedia.org/wiki/Path_tracing

    An image rendered using path tracing, demonstrating notable features of the technique. Path tracing is a rendering algorithm in computer graphics that simulates how light interacts with objects, voxels, and participating media to generate realistic (physically plausible) images.

  3. Computer graphics lighting - Wikipedia

    en.wikipedia.org/wiki/Computer_graphics_lighting

    Computer graphics lighting is the collection of techniques used to simulate light in computer graphics scenes. While lighting techniques offer flexibility in the level of detail and functionality available, they also operate at different levels of computational demand and complexity. Graphics artists can choose from a variety of light sources ...

  4. Volumetric path tracing - Wikipedia

    en.wikipedia.org/wiki/Volumetric_path_tracing

    Volumetric path tracing is a method for rendering images in computer graphics which was first introduced by Lafortune and Willems. [1] This method enhances the rendering of the lighting in a scene by extending the path tracing method with the effect of light scattering. It is used for photorealistic effects of participating media like fire ...

  5. Physically based rendering - Wikipedia

    en.wikipedia.org/wiki/Physically_based_rendering

    Physically based rendering (PBR) is a computer graphics approach that seeks to render images in a way that models the lights and surfaces with optics in the real world. It is often referred to as "Physically Based Lighting" or "Physically Based Shading". Many PBR pipelines aim to achieve photorealism.

  6. Precomputed Radiance Transfer - Wikipedia

    en.wikipedia.org/wiki/Precomputed_Radiance_Transfer

    Precomputed Radiance Transfer (PRT) is a computer graphics technique used to render a scene in real time with complex light interactions being precomputed to save time. Radiosity methods can be used to determine the diffuse lighting of the scene, however PRT offers a method to dynamically change the lighting environment. [1]

  7. Radiosity (computer graphics) - Wikipedia

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

    The radiosity method, in the context of computer graphics, derives from (and is fundamentally the same as) the radiosity method in heat transfer. In this context, radiosity is the total radiative flux (both reflected and re-radiated) leaving a surface; this is also sometimes known as radiant exitance .

  8. Shader - Wikipedia

    en.wikipedia.org/wiki/Shader

    In computer graphics, a shader is a computer program that calculates the appropriate levels of light, darkness, and color during the rendering of a 3D scene—a process known as shading. Shaders have evolved to perform a variety of specialized functions in computer graphics special effects and video post-processing , as well as general-purpose ...

  9. Global illumination - Wikipedia

    en.wikipedia.org/wiki/Global_illumination

    Global illumination [1] (GI), or indirect illumination, is a group of algorithms used in 3D computer graphics that are meant to add more realistic lighting to 3D scenes. Such algorithms take into account not only the light that comes directly from a light source (direct illumination), but also subsequent cases in which light rays from the same source are reflected by other surfaces in the ...
