edge blend

OpenGL "Duplicating"

Hi there,

I cannot figure this out:

I am trying to do edgeblending strictly with GL – no core image.

The masking is easy. My problem is that I have to have something like 150px overlap between my 3 projectors.

Can I somehow show the same part of a GL scene in two different places?

Does it make sense?

Render In Image is banned :)

best,

soren
