2. High-dynamic-range rendering - Wikipedia

   en.wikipedia.org/wiki/High-dynamic-range_rendering

   The use of high-dynamic-range imaging (HDRI) in computer graphics was introduced by Greg Ward in 1985 with his open-source Radiance rendering and lighting simulation software which created the first file format to retain a high-dynamic-range image. HDRI languished for more than a decade, held back by limited computing power, storage, and ...

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. Bloom (shader effect) - Wikipedia

   en.wikipedia.org/wiki/Bloom_(shader_effect)

   Bloom (sometimes referred to as light bloom or glow) is a computer graphics effect used in video games, demos, and high-dynamic-range rendering (HDRR) to reproduce an imaging artifact of real-world cameras. The effect produces fringes (or feathers) of light extending from the borders of bright areas in an image, contributing to the illusion of ...

5. Three-point lighting - Wikipedia

   en.wikipedia.org/wiki/Three-point_lighting

   Three-point lighting is a standard method used in visual media such as theatre, video, film, still photography, computer-generated imagery and 3D computer graphics. [1] By using three separate positions, the photographer can illuminate the shot's subject (such as a person) however desired, while also controlling (or eliminating) the shading and ...

6. 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 ...

8. Physically based rendering - Wikipedia

   en.wikipedia.org/wiki/Physically_based_rendering

   Even though this is a rough, opaque surface, more than just diffuse light is reflected from the brighter side of the material, creating small highlights, because "everything is shiny" in the physically-based rendering model of the real world. Tessellation is used to generate an object mesh from a heightmap and normal map, creating greater detail.

9. Ray tracing (graphics) - Wikipedia

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

   While the direct illumination is generally best sampled using eye-based ray tracing, certain indirect effects can benefit from rays generated from the lights. Caustics are bright patterns caused by the focusing of light off a wide reflective region onto a narrow area of (near-)diffuse surface. An algorithm that casts rays directly from lights ...
