The purpose is to project an image over a poster, and the shapes (rectangles) must match the music systems in the poster as well. I already noticed that it's quite impossible to do this only by moving the projector, so I added commands in the patch to move the gem window and it's contents on all 3 axes, makes it much easier to set. I was thinking also of adding the possibility of making a trapeze function for each corner: any suggestion on which object to use? Any other real-life suggestion on how to make the projection easier?
the extended view toolkit (© peter venus, marian weger and cyrille henry) provides a way to do projection mapping with Gem: <http://extendedview.mur.at>
