Quad projector blend
I have to do a quad projector blend soon and I realised it is problematic in Isadora, but maybe I am wrong. I need to use 4 projectors to make a big rectangle. There will be a rectangle in the middle where all projectors are running at once. I cant think of a way for Izzy to deal with this but maybe someone out there can? Here is an image of the overlaps for the blend.
I think its ok.
When I do a white stage with 2 edges blended as you would need. I get something like:
Notice the corner is double faded (both gradient alphas are applied)
When I duplicate this layer and flip it about so that 4 copies are laid out like your example, I seem to get them adding together smoothly.
