this is still a lot for real time in the CPU.
It´s not realtime and it does not have to be realtime. It´s more like a
render job for pd/GEM in single buffered mode.
you can have 2 array : the unsorted, and the sorted. then interpolate
between 2.
Yes, I will give it a try. At least it should make sense in a visual way. I
dont want tons of colored noisy pixels...
Cheers,
Rainer
