I doubt it.   The whole radiosity mechanism is completely different from the
typical raytracing from a light source way of doing things - the way I
understand it is, basically every object in your scene is treated as a "light
source" since a lot of the point of radiosity is picking up and transferring the
color of surrounding objects to a surface via reflected ambient light.

So, if you had a room painted blue, and put a white box on a table, and shone a
light onto one of the walls, the box would appear blue - because it would be lit
only by the blue light reflected from the walls.   That sort of thing.

The real trick is understanding and properly adjusting the settings to get a
good result.   I'd start by using some of the radiosity levels in the include
file "rad.inc" or whatever it's called....
