Color bleeding real time (Lightsprint middle-ware)In computer graphics and 3D rendering, color bleeding is the phenomenon in which objects or surfaces are colored by reflection of colored light from nearby surfaces.

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 ...
[2] Since 2019, however, hardware acceleration for real-time ray tracing has become standard on new commercial graphics cards, and graphics APIs have followed suit, allowing developers to use hybrid ray tracing and rasterization-based rendering in games and other real-time applications with a lesser hit to frame render times.
However, it is a very crude approximation to full global illumination. The appearance achieved by ambient occlusion alone is similar to the way an object might appear on an overcast day. The first method that allowed simulating ambient occlusion in real time was developed by the research and development department of Crytek ( CryEngine 2 ). [ 2 ]
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.
Maxwell Render was released to the public as an early alpha in December 2004 (after two years of internal development) utilizing a global illumination (GI) algorithm based on a metropolis light transport variation. [5] Next Limit Technologies released its latest version of Maxwell Render V4.2 in February 2018. [6]
