plane flattening and interleaving with Gen?
I’m slogging my way through tutorials but maybe somebody could give me some direction or guidance! I think what I want to do is swiz the matrix into rgb and then combine the values sequentially into a 1 char matrix, which I can then jit.spill. But I think all matrices in Gen are 4 plane, and maybe its not possible to sequence the r, g and b in the right order because of the "synchronicity" of Gen. I was also thinking maybe I could take the swizzed r, g, b data and pack it into, say, the alpha channel of a matrix (that is 3 times the duration of the source matrix) so that I could jit.spill it out once all properly interleaved.
Any ideas would be much appreciated!
Gen as it stands right now only works with inputs and outputs that have the same matrix format. For example, if you send a [4 char 320 240] matrix to jit.gen, you’ll get a [4 char 320 240] matrix out. There’s no way to get a [1 char 960 240] matrix, which is what it seems like you want.
The fastest way to flatten a matrix is to use jit.coerce. The other option is to use jit.multiplex and jit.unpack. Here are both solutions:

Thanks Wesley, looks like jit.coerce has been the easy way to do this all along ;) Always wondered what it did ("header munging" ?!??)
