or GI. A superset of the radiosity and raytracing rendering techniques. The goal of Global Illumination rendering is to compute all of the possible light interactions between surfaces in a given scene, and thus obtain a truly photorealistic image. All combinations of diffuse and specular reflections and transmissions must be accounted for. Effects such as colour bleeding and caustics must also be included in a global illumination simulation.
FinalRender (used by MadTom Productions) can calculate Global Illumination.
