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.
