How to turn the page [digital libraries]
Yi-Chun Chu, Ian H. Witten, R. Lobb, David Bainbridge · 2004
Can digital libraries provide a reading experience that more closely resembles a real book than a scrolled or paginated electronic display? We describe a prototype page turning system that realistically animates full three-dimensional page-turns. The dynamic behavior is generated by a mass-spring model defined on a rectangular grid of particles. The prototype takes a PDF or e-book file, renders it into a sequence of PNG images representing individual pages, and animates the page-turns under user control. The simulation behaves fairly naturally, although more computer graphics work is required to perfect it.
