Interactive Deformation of Virtual Paper

Abstract

Although paper is a very common material in our every-day life, it can hardly be found in 3D virtual environments. Indeed, due to its fibrous structure, paper material exhibits complex deformations and sound behavior which are hard to reproduce efficiently using standard methods. Most notably, the deforming surface of a sheet of paper is constantly isometric to its 2D pattern, and may be crumpled or torn leading to sharp and fine geometrical features. During deformation, paper material also has very characteristic sound, which highly depends on its complex shape. In this thesis, we propose to combine usual physics-based simulation with new procedu- ral, geometric methods in order to take advantage of prior knowledge to efficiently model the geometry and the sound of a deforming sheet of paper. Our goals are to reproduce a plausible behavior of paper rather than an entirely physically accurate one in order to enable a user to interactively deform and create animation of virtual paper.
