Position Based Dynamic

Position-based dynamics (PBD) is a computational method for simulating the motion of objects, particularly deformable ones like cloth or ropes, focusing on achieving efficient and stable simulations. Current research emphasizes extending PBD's capabilities through differentiable formulations, enabling gradient-based optimization for tasks like robot control and parameter estimation within frameworks such as extended PBD (XPBD). This allows for the development of more robust and adaptable control strategies for robotic manipulation of complex objects, with applications ranging from automated laundry folding to surgical robotics. The integration of PBD with other techniques, like graph-based models for interacting objects and neural radiance fields for visual intuitive physics, further expands its applicability and impact.
