Hi!
Is there a maximum number of assembly language instructions to be loaded into the fragment program unit? I have an algorithm on to port from cpu to gpu and apparently it doesn't fit on the gpu.

I am currently writing the positions of my geometry to the RGB channels of gl_FragColor and I would like to write 1.0 to the alpha channel if the fragment is part of geometry, and 0.0 if its empty.
Is there a simple way to tell if a fragment is geometry or not? Maybe through gl_FragCoord.z?
thanks

My 330 shaders look like…
