We are about to switch to a new forum software. Until then we have removed the registration on this forum.
I am trying to figure out if there are any new techniques out there for doing projection mapping either within processing or using a third party software. I am aware of keystone and the other libraries that use the Java Advanced Imaging homography method to project a pgraphics canvas onto a plane but I am looking for a different, hopefully more complete, solution.
I want to be able to project a whole 3d scene back onto its physical equivalent. Specifically I want to recreate the physical scene in 3d in processing, transform/manipulate the 3d geometry and then project back on the physical scene. Essentially the problem comes down to calibrating a 3d view of the scene to the physical geometry and project it.
Any info or advice would be greatly appreciated.
