Using [js] to Process an Incoming Matrix?
I began looking at the js tutorials for jitter, and it seems all the movies get loaded within the js object. Is it possible to have a matrix go into the js object and then process it from there? or does the matrix data either have to be generated or read while inside the js object?
I know you could do it in [js] but not sure how, someone on here will know.
You could also use jit.submatrix maybe, or the srcdim/dstdim messages to take parts from the original and put it into a new one. So you’d have a long rapid-fire list of commands to that instead of all the patch cables, probably you could figure something out with [preset] to decide how things are chopped and rearranged (and how much control you want over that process).
Maybe two [matrixctrls] with one cell per matrix enabled: click the first (in a 16×16 grid) to select source, click the other for destination. [preset] or some math-generated functions (and [random] and [urn] could help too) could do the clicking for you…
my idea with the matrix was to simply have each square connected to a matrix cell, so if i have a 16×16 division of the matrix, i’d have 256 inputs/outputs for the matrix. was going to use random processes (triggered through amp analysis) to reorganize the squares.
i like the idea of using src/dst dim messages. it seems that text coding (ie js) using arrays/for loops would be better suited for this kind of thing, but i’ll figure something out using uzi (uzi = max for loop for me). thanks for the suggestion :)
Yes, if you want to do it in straight Jitter (no js), uzi and a little math will do the trick. Although the coding would be more explicit in js, I don’t know how it would stack up in terms of computation speed. Here’s an all-Max example. It’s got lots of hard coded numbers in it that are based on a 720×480 source image and a 16×16 grid, and it chooses the reordering randomly, but it shows the basic idea.
