1. A method, comprising: receiving a rest pose mesh comprising a plurality of faces, a rigidity map corresponding to the rest pose mesh, and a deformed pose mesh; using the rigidity map to generate a simulation grid on the rest pose mesh, the simulation grid comprising a plurality of cells; defining a set of constraints on the simulation grid, the constraints being derived at least in part from the rigidity map; running a simulation using the simulation grid and the set of constraints to obtain a warped grid; and texture mapping the deformed pose mesh based on data from the warped grid.
