ABSTRACT
The simulation of cloth with rich folds and wrinkles is a computationally expensive process. In this paper, we introduce an example-based algorithm for fast animation of plausible cloth wrinkles. Our algorithm does not depend on a character's pose, therefore it is valid for loose dresses, curtains, etc., not just cloth defined by skinning techniques. Central to our approach is a correspondence between low and high-resolution cloth deformations, both at the training and synthesis stages. Based on this correspondence, we define an algorithm for synthesizing cloth wrinkles as a function of the deformation of a low-resolution cloth and a set of example poses. We demonstrate the animation of plausible high-resolution wrinkles at high frame rates, suitable for interactive applications such as video games.
