This may just be me but I cannot believe that doing real-time
rendering would be faster than a bitmap lookup? Am I just missing
something? The other problem is that the rendered images that you are
doing on the fly will not be able to have the same 'quality' in
certain instances. I am just imagining that here we have some midi
control changing parameters while we are playing a stream or
something. Lets say maybe three of four different knobs and sliders
are changing. To me that seems like a TON of extra overhead for
rendering each of those frames.
FWIW,
Rick
