Creating animated pop-up books from the motion of 3D articulated characters

Pop-up books are interesting books containing paper pieces that pop-out to form 3D structures when opened. But more than just depicting 3D objects, pop-up artists also use the movement of the paper pieces during the opening process to reproduce animations. Artists have used this technique to create pop-ups of persons swimming, running and objects peeping out. In this work, we study the movement of paper pieces in different pop-up mechanisms with the goal to use this knowledge to automatically design animated pop-ups from the motion of articulated 3D models.
