| Class | Description | 
|---|---|
| ConeJoint | From bullet manual: To create ragdolls, the cone twist constraint is very useful for limbs like the upper arm. | 
| HingeJoint | From bullet manual: Hinge constraint, or revolute joint restricts two additional angular degrees of freedom, so the body can only rotate around one axis, the hinge axis. | 
| PhysicsJoint | PhysicsJoint - Basic Phyiscs Joint | 
| Point2PointJoint | From bullet manual: Point to point constraint, also known as ball socket joint limits the translation so that the local pivot points of 2 rigidbodies match in worldspace. | 
| SixDofJoint | From bullet manual: This generic constraint can emulate a variety of standard constraints, by configuring each of the 6 degrees of freedom (dof). | 
| SliderJoint | From bullet manual: The slider constraint allows the body to rotate around one axis and translate along this axis. |
