I was just wondering if anyone had actually used block~ in a size different than a power of two... and in what specific situation, for what kind of processing.
It's not clear how it is supposed to work for video processing.
using the right block size we could imagine having a pix_dump~ and pix_set~ (for Gem image)
miller did :-) to change a 3D geometry control points.
anyway, it seems no one has ever done anything with it :)
it is very useful for audio.
it seems useless for audio, as most objects will restrict themselves to a power of two.
you can generated a lot's of audio data in one click. this data can be stored in a table, or in a wav file on the disk.
for exemple, enveloppe table (for granular synthesis, fft analysis, etc) can be generated in a loadbang.

c
bang~, for example, will bang at every 128 samples when block is at 100 in size.
cheers

I can't read Miller's mind, of course, but I could imagine that the idea
is to have arbitrary block sizes so that it is possible to match the
block size to video frames or lines of a video frame or whatever. Then
you could use Pd's DSP engine to process video data in real time.
Does that answer your question?
