Dubois Anaglyph Nuke Gizmo
by flord on Apr.05, 2011, under Nuke
I don’t remember how I stumbled on Eric Dubois’ page on how to create an optimized anaglyph while keeping the colors, but I do remember that I thought it was semi useless since I always do my anaglyphs in black and white, it just works so much better. Even the default anaglyph node in Nuke creates black and white images.
Since I’m working on IMAX projects at the moment, I often use the proxy mode and I quickly realized that the anaglyph node’s offset parameter isn’t constant when activating the proxy. So I thought I would do my own anaglyph node. And then I remembered Eric Dubois’ method which was just a color matrix in linear space. It couldn’t be simpler to implement in Nuke. After experimenting a bit with it, I must say this method is awesome. I am surprised to see nobody did a Nuke gizmo before me, or that they didn’t publish it.
Haven’t used it much yet, but I doubt there should be any problems with it. It complains when you don’t have ‘left’ and ‘right’ views, but why would you do that? 
I also uploaded the gizmo on nukepedia. http://www.nukepedia.com/gizmos/duboisanaglyph
At the time of this writing, it’s still waiting for moderation.
