This limit is often used to limit the rotation of ragdoll joints. AnchorOrientationALocal defines a coordinate frame fixed on the first body. AnchorOrientationBLocal defines a coordinate frame fixed on the second body. Twist is defined as the rotation of the x-axis (x is the twist axis). Swing is defined as the deviation of the x-axes. The y- and the z-axes fixed on the first body are the swing axes. The twist and swing values are angles in the range [-π, π]. Using the properties Minimum and Maximum the twist and swing angles can be limited. Limiting the swing angles creates a limit cone. Different minimum and maximum swing limits can be chosen for the swing axes. This can be used to create a deformed limit cone.

This constraint should not be used if the swing on a swing axis is locked (minimum and maximum is set to 0). In this case a different constraint type should be used (e.g. a HingeJoint). Using very non-uniform swing limits is also not recommended. The swing limits appear "smoother" if the cone is symmetric.
