Connect a point on the first body with a point on the second body. Points are defined within the bodies’ local coordinate systems.
Keep two bodies connected with each other and limit the freedom of rotation. Useful for e.g. connecting a window to a window frame, or to connect a wheel to a car.
Keep the centers of two bodies at the constant distance from each other.
Constraint allows to limit the freedom of movement of two bodies with relation to each other.
