virtual math::Vector3 gazebo::physics::DARTHingeJoint::GetAnchor ( unsigned int  _index) const
virtual

Get the anchor point.

Parameters
[in]_indexIndex of the axis.
Returns
Anchor value for the axis.

Returns
Axis value for the provided index.

Implements gazebo::physics::Joint.

virtual double gazebo::physics::DARTHingeJoint::GetMaxForce ( unsigned int  _index)
virtual

Get the max allowed force of an axis(index).
