There is a long tradition of referring to books as two-dimensional objects usually made of paper. Our project deals with paper-objects, too. But digitising and modelling 19th century movable books by the German illustrator Lothar Meggendorfer, the project BeWeB-3D aims at computer-made models of animated 19 th century paper-engineered objects, which enable interaction. The human actor has to be put in a position to trigger the movement of the model. The project is located at Staatsbibliothek zu Berlin and funded by Germany–s Federal Ministry of Education and Research (BMBF).
