Hello,
I'm working on porting Andrew Benson's optical flow glsl shaders over
to PD. I've got the primary shader working, but need to send the
output to the second shader. I figured that the best way to deal with
this would be to use [gemframebuffer] to send the results of my first
chain
hello,
you have to use frambuffer in order to chain multiple shader.
there are example for this in the glsl section of Gem help.
the most common problem with gemframbuffer is that you need to add a
translateXYZ 0 0 -4 after the gemhead in order to have the same vision point
than without the
Thanks so much! [translateXYZ 0 0 -4] is just what I needed. I realize
now that last time I needed to use [gemframebuffer] I went through
this same period of confusion.
Can someone update the [gemframebuffer] help patch to explain this anomaly?
