ABSTRACT
We present a method for controlling topology morphing physically simulated elastoplastic objects. Our method utilizes space-time control of differentiable material point method simulation via per-particle deformation gradients. We base our simulation environment on the material point method due to its natural ability to handle topology change. Our method can generate short animations or produce indefinitely long sequences via a novel chained optimization technique.
