Researchers have introduced RiCo, a novel neural simulation method for rigid-body interactions that focuses on local contact reasoning. Unlike global approaches, RiCo models interactions through sparse neighborhoods of contact surface points, combining state, geometry, motion, and physical properties of nearby surfaces. This localized approach allows for higher accuracy and contact fidelity, reducing position and orientation errors by up to 38% on the MOVi-benchmark. RiCo also demonstrates zero-shot generalization to larger scenes and shows preliminary evidence of sim-to-real transfer in real-world multi-ball collision experiments. AI
