ABSTRACT
We present a new, Eulerian-on-Lagrangian approach for modeling cloth. When a cloth modeled using the traditional Lagrangian approach is moved around an object with sharp corners, such as the edge of a table, the cloth cannot always bend smoothly around the object because it can bend only at its nodes. With our method, these constraints are built into the discretization of the cloth, giving us an equation of motion that directly honors these constraints. This allows the cloth to bend and move smoothly around such constraints. We show how our method can efficiently handle challenging simulations, such as pulling a table cloth from under wine glasses without knocking them over.

Eulerian-on-lagrangian cloth simulation
We resolve the longstanding problem of simulating the contact-mediated interaction of cloth and sharp geometric features by introducing an Eulerian-on-Lagrangian (EOL) approach to cloth simulation. Unlike traditional Lagrangian approaches to cloth ...
An art-directed wrinkle system for CG character clothing and skin
We present a kinematic system for creating art-directed clothing and skin wrinkles on CG characters used in the production of computer-animated feature films. This system employs a curve-based method for generating wrinkles on reference poses, which are ...
Exploring physical information cloth on a multitouch table
ITS '11: Proceedings of the ACM International Conference on Interactive Tabletops and SurfacesWe expand multitouch tabletop information exploration by placing 2D information on a physically-based cloth in a shallow 3D viewing environment. Instead of offering 2D information on a rigid window or screen, we place our information on a soft flexible ...
