Looking at this graph
(http://csgillespie.files.wordpress.com/2011/01/gpu3.png) got me
thinking about using the GPU through GLSL to process samples. Given
that there are lots of optimized functions built into GLSL for
calculating 32bit rbga values (clamping, interpolation, etc) and that
GPUs are so fast with floating point ops this seems like an
interesting idea.
This being a rather obvious idea I doubt it is original, and has
probably been discussed here before, but I couldn't find anything in
the archives. Can anyone explain to me the obstacles involved or why
this method is not viable? Especially on iOS? Will someone burst my
bubble?
