Radiosity is a technique to calculate indirect light. Specifically, radiosity
calculates the interreflections of diffuse light among all the surfaces in your
scene. To make this calculation, radiosity takes into account the lighting
you’ve set up, the materials you’ve applied, and environment settings you’ve
made.
The radiosity processing of a scene is distinct from the rendering process. You
can render without radiosity. However, to render with radiosity, you must
always calculate radiosity first.
Once a radiosity solution for a scene has been calculated, it can be used in
multiple renderings, including multiple frames of an animation. If there are
moving objects in the scene, radiosity might need to be recalculated; see
Animation with Radiosity on page 5994 .

NOTE Radiosity is also known as global illumination .
IMPORTANT If the dimensions of your scene are not realistic, then radiosity will
not show realistic lighting, either.
