Rig-Based Physics Simulation

A method comprising:

• receiving an animation rig with a plurality of rig parameters, the rig parameters defining a deformation space for an attached surface mesh, the attached surface mesh comprising a plurality of nodes;
• performing a physics-based simulation, the simulation being constrained by the deformation space;
• and
• generating keyframes on the rig based on the results of the simulation.

A non-transitory computer readable medium comprising an instruction set configured to cause a computing device to perform:

• receiving an animation rig with a plurality of rig parameters, the rig parameters defining a deformation space for an attached surface mesh, the attached surface mesh comprising a plurality of nodes;
• receiving material stiffness data on a subset of the rig parameters,
• using the rig and the material stiffness data to influence a physics-based simulation that is constrained by the deformation space of the rig;
• and
• generating keyframes on some or all of the rig parameters as a result of the simulation.
