Ok, I've read up on ray-tracing long ago and understand how it works...but I've
yet to see a quick description (or a long one for that mater) of how
radiosity based rendering works.

Would anyone care to offer a quick description of the radiosity process?  ie:
what is it based on, and roughly how does it work.  I know you can explain
Ray-tracing (briefly) in as little as one paragraph, is radiosity as simple?

If you've got any good (easy to get) references on radiosity, I would like
to hear about them.

I'm particularly interested in the property of radiosity that HP has talked
about in their workstations.  If I understand them right, once you have 
calculated the image you can "look" at it from any position without having
to re-calculate the image.  Is this true for all radiosity based rendering
package or has HP done something special with their custom hardware?

Thanks!
