Abstract: Rigid body simulation with constraints offers a well-established and robust approach to a wide range of physical phenomena, offering great flexibility by allowing custom constraints. This includes elastic or plastic simulations more commonly handled by mass-spring systems or position-based dynamics. In this paper, we present a simple but functional real-time physics simulation based on rigid body dynamics with pre-defined and contact constraints, and explore its applicability in cloth, hair, and ragdoll simulation. We compare our results against those achieved with position-based dynamics.
