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;
• texture mapping the deformed pose mesh based on data from the warped grid;
• and
• marking each edge of each face contained in the simulated faces subset with one of three states:
• a first state indicating that the marked edge borders a face that will not be simulated, or does not border a face at all;
• a second state indicating that the marked edge borders a face that has already been simulated;
• and
• a third state indicating that the marked edge borders a face that will be simulated later.
