Hi everyone - I've programmed quite a bit of Max but am a little at a loss for the initiatory steps for an idea I have, as my jitter skills are somewhat limited. I'd like to create a patch that can take a picture, analyze it, and map GL lines to recreate the lines in the picture. I'd imagine I'd begin by using jit.rgb2luma, and then analyze the difference between pixels and at points where pixels have a higher difference, you could map a line. I know there has to be some jitter math whereby I could analyze a matrix and determine these locations in a somewhat succinct way. I'm not an "expr"ert, so I'm not quite sure of the math. Could someone push me in the right direction? Thanks!
