Which makes a lot of sense memory wise. If you have a 200
frame animation and parsed once you would have to store in
memory every iteration of the changes in the reflected rays in
the scene. I would think you would also increase the initial
parsing time to an uncomfortable level to do the calculations
for each iteration.. Maybe for one object against a black
background this penalty wouldn't be too high but what if you
had several objects moving down a mirrored hallway with 12
colored lights bouncing off of the objects and the walls of the
hall ? I shudder to think of the wait.
Just my thoughts on the subject.
