hey there. forgive me a bit as I acclimate (long time MaxMSP user
working in Pd).
In Max (Jitter) I've built a lot around jit.peek~
Often this involves reading a one plane matrix at points specified by
two signal inputs. The matrix is a still image or video. One input
signal species which row, the other input signal specifies which column
and out comes an appropriate signal value.
attached patch does this with gridflow (for image stuff) and zexy (for
tabdump). quality leaves much to be desired (no anti-aliasing /
interpolation, and i only tried with 8-bit images...)
I see that in GEM there are pix_pix2sigs~ and pix_sig2pix~ which on
first glance look promising.
So:
1. Any pointers out there for treating image as sound in Pd,
specifically looking at sonification (not visualization or simultaneous
audio-visual synthesis)?
2. Any uses of pix_pix2sig~ or pix_sig2pix~ which I should look at
beyond the help files?
3. Any strategies for treating each column of an image as an array (i.
e. the array contents update based on which column of an image is loaded)?
4. Do I need something else beyond the current Pd-extended (like
GridFlow)?
Thanks! and all best,
shawn
