Pin joint for 3D PhysicsBodies.

Description
-----------

Pin joint for 3D rigid bodies. It pins 2 bodies (dynamic or static) together. See also :ref:`Generic6DOFJoint3D<class_Generic6DOFJoint3D>`.

Enumerations
------------

.. _enum_PinJoint3D_Param:

.. _class_PinJoint3D_constant_PARAM_BIAS:

.. _class_PinJoint3D_constant_PARAM_DAMPING:

.. _class_PinJoint3D_constant_PARAM_IMPULSE_CLAMP:

enum **Param**:

- **PARAM_BIAS** = **0** --- The force with which the pinned objects stay in positional relation to each other. The higher, the stronger.

- **PARAM_DAMPING** = **1** --- The force with which the pinned objects stay in velocity relation to each other. The higher, the stronger.

- **PARAM_IMPULSE_CLAMP** = **2** --- If above 0, this value is the maximum value for an impulse that this Joint3D produces.

Returns the value of the specified parameter.
