Hmm, I've always assumed that POV throws away any mosaic info without using
it for any subsequent action (except for radiosity), and that any other
renderer must do the same.
After all, calculating that an area x pixels by x pixels is dark green on
average does nothing helpful when it comes to calculating the colour of an
individual pixel. The only exception I can think of is if the average is rgb
0 or rgb 1 (or whatever the appropriate equivalent is).
If this isn't the case with either POV or Bryce, can someone give me an
idiot's explanation of how the info is used?
(and BTW that's an explanation FOR and idiot, not BY one)
