M.C. Escher’s two dimensional lithographs and wood carvings of impossible structures have been fascinating people’s imaginations for decades. Gershon Elber, a computer science professor at the Israel Institute of Technology, has developed a way to bring Escher’s work to life by using 3D printing — specifically the PolyJet process from Objet.
Professor Elber manipulated the optical illusions using CAD software, allowing him to fabricate the real life versions of Eschers’ drawings. Please have a look at the below video on how this was achieved – seeing is believing.
