FracGen: Learning How Objects Stretch and Tear with Physics-Informed Video Generation

FracGen is a fracture‑aware video generation model that creates realistic, controllable fracture dynamics from a single intact image, guided by physics signals. It is trained using FracSim, a simulation framework that extends material point method (MPM) with a continuum damage model to produce paired fracture videos and dense physical fields. The model jointly predicts RGB video and physical maps, employing physics‑informed losses to capture material‑specific fracture behavior and enabling fine‑grained control over tear location, crack speed, and deformation before failure.
