No idea what "renderosity" lighting is. ;-) I'm assuming you mean, Radiosity?

There's Global Illumination (which is a general term describing the method of lighting that attempts to capture more realistic results by trying to immitate how light behaves in the 'real world'). GI has different sub-genres and techniques; like IBL (Image Based Lighting), HDRI (A type of IBL that uses high dynamic range images), Radiosity (a more accurate implimentation of the way light bounces around between objects in a scene, producing realistic light transfer and color bleeding).

These are some of the more common terms used in 3D, but there's different sub-standards to each of these as well. It can get very complex.

Poser 6 can do simple IBL (using standard images a the basis for lighting a scene), but can not use HDRI (high dynamic range images). You can also "fake" global illumination in just about any application using a series of standard lights, forming a 360 degree or 180 degree dome over your scene. In Poser, however, this method can take up a vast amount of resources and slow renders drastically, depending on how many lights you need. Poser 6 impliments IBL in a very efficient and "cost" effective way. However, shadows from the ambient light it produces need to be generated with ambient occlusion (AO), which is a raytraced method of calculating the distance and angle between surfaces, and this can be costly in some cases.
