jit.repos lcd cut and paste

March 21, 2006 | 2:21 pm

I like the repos object
http://www.vcnet.com/~franz/max/vid.reposin.htm
shows my projects with it
I was building kaliedscopes with it by cutting out masked triangles from the
original 2 plane 1-256 1|256 xy mask that looks like a green rainbow that is
a non distorted positioning matrix and then twirling and recombining the
fragments
I was even thinking of printing out those color fields and trying to do
realtime repositioning with the camera watching me bend the color plate
masks
Ive been working in a matrix thats only 256 by 256 because the lcd
enviroment is limited to those numbers in rgb, but if I wanted to do cut and
paste work on a 640 by 480 matrix coordinates I would never be able to "see"
the entire mask at once in a graphicinterface for the collage process, does
it sound plausable to use jit.lcd to create a white triangle in a blackmask
then transfere it into float 32 and jit.op it to big numbers like (400,600)
area of the float 32 matrix, then skiping the visualization of the mask just
go straight to seeing the effect on the through matrix to jit.reposin?

additionaly a feedback question, jitter makes it pretty stream lined to do
pixel feedback with jit.rota and jit.submatrix but has anyone tried to do
feedback involving jit.reposin’s position matrix, I often use jit.map to
stop the out of bounds chaos that reposin is so stubborn against, but
imagine pisel position feedback and pixel colorfeedback both working their
chaosmagic in different directions together
