This brings React Three Fiber physics through the Rapier engine, giving you RigidBody components, colliders, forces, and joints for 3D web scenes. You wrap your meshes in RigidBody tags, set types like dynamic or fixed, and let gravity and collisions handle the rest. The colliders auto-generate from geometry or you can place them manually with CuboidCollider, BallCollider, and friends. Forces apply through refs with methods like applyImpulse and addForce. It's genuinely well designed for the R3F ecosystem, the debug wireframes are helpful, and the on-demand rendering integration means physics don't tank your frame rate when nothing's moving.
