This is an example of real time radiosity rendering, radiosity realistically simulates the way that light interacts in a environment. For example reflecting off mirrors and bouncing off the floor up underneath surfaces. Using radiosity a scene looks more realistic, as light reflects off surfaces and illuminates shadowed surfaces.  

Without light render engines we would be left with solid shadows in environments, which is useful also because it will render quickly and you may not need to see all the lighting effects when just constructing the models and surfaces of an environment.

The radiosity lighting also uses photometric units which determine lighting effects based on spectrums visible to the human eye (Candelas) and also the power of light (Lumens) you can say “the power of this bulb is 10000 lumens”  

            In rendering there are 2 main types of illumination rendering algorithms which are Local and Global. Local is the simplest and fastest technique to illuminate an image with 3d shading. A local illumination algorithm will only describe how individual surfaces reflect or transmit light. This is an example of a environment rendered with a local illumination rendering algorithm.         A global illumination algorithm calculate the ways which light is transferred between surfaces. The goal of the global illumination algorithm is to recreate the environment as if you saw the environment  in real life .  

This is an example of rendering without Global illumination. You can see the light casting shadows but the light is not reflecting off objects. The light is actually a lamp and there is a green wall but we can’t see it because the light can’t reach those surfaces.

This is an example of rendering with global illumination. You can now see the lamp and green wall also the reflected light on the red wall from the glass ball next to it.

An algorithm is a defined task which reaches (or calculates) an end product.

3DS max uses 2 main Global illumination algorithms which are Radiosity and Ray tracing. The Ray tracing algorithm can model a large variety of lighting effects and can accurately account for characteristics of shadows, secular reflections (mirrors) and direct illumination. In 3DS Max Radiosity and Raytracing work together to accomidate most of the needed lighting effects you would encounted in 3d animation.
