Query: Locking-free Simulation of Isometric Thin Plates   To efficiently simulate very thin, inextensible materials like cloth or
paper, it is tempting to replace force-based thin-plate dynamics with hard
isometry constraints. Unfortunately, naive formulations of the constraints
induce membrane locking---artificial stiffening of bending modes due to the
inability of discrete kinematics to reproduce exact isometries. We propose a
simple set of meshless isometry constraints, based on moving-least-squares
averaging of the strain tensor, which do not lock, and which can be easily
incorporated into standard constrained Lagrangian dynamics integration.
