In this paper, we present a set of experiments in which we explore some factors that contribute to the perception of cloth, to determine how efficiency could be improved without sacrificing realism.

This paper applies the algebraic multigrid method known as smoothed aggregation to cloth simulation.

This paper presents a scalable implementation of the Asynchronous Contact Mechanics (ACM) algorithm, a reliable method to simulate flexible material subject to complex collisions and contact geometries.

Computation of bending forces on triangle meshes is required for numerous simulation and geometry processing applications.

We present a new algorithm for near-interactive simulation of skeleton driven, high resolution elasticity models.

We show that physically based shading models fail to provide Intuitive artist controls and we introduce a novel approach for creating an art-directable hair shading model from existing physically based models.

We extend the Asynchronous Contact Mechanics algorithm [Harmon et al. 2009] and improve its performance by two orders of magnitude, using only optimizations that do not compromise ACM’s three guarantees of safety, progress, and correctness.

We present a fail-safe that cancels impact but not sliding motion, considerably reducing artificial dissipation.

We propose a technique to control the temporal noise present in sketchy animations.

We present Smart Scribble, a new scribble-based interface for user-guided segmentation of digital sketchy drawings.
