Digitization and 3D Modeling of Movable Books by Jérôme Dupire. This work on books with complex pages. I would call constructed books, pop-up books, hidden object books, and like.
Earlier work with “flat pages” presented at CIFED 04, JCDL 02, ACM DL 98, SIGGRAPH web3d 01
All done with object oriented programming.
Much like Das project in the earlier work.
