Homography Chaos

Hello Community,

I should be getting this, but transforms drive me insane. I’ve attached a patch, where three quads should be displayed. All should be transformable and skewable by homography and transform-node. But they aren’t. Can anybody hint me, at what I missed?

Hey… check the homography help patch… you’ll notice that the homography output should be connected to the renderer’s projection pin… as i’m not at my computer I cannot give you more than that… hope it helps!

Hey parabola. Thanks for the advice. I don’t want to change the projection-matrix, though, this will be done later with a different matrix (e.g. projector). I want the Quad itself be deformed. That works fine with just one quad, but with three there’s the problem.

I Just noticed a mistake with the initial transform, and corrected it. But that didn’t change the original problem. Here’s the updated patch…

Hey DiMiX thanks to your patch I found the mistake. My Spread of Values was somehow scrambled and that select-node was not necessary. It was not a logic-problem, just the wrong values. Thank you alot :-)
