[in] pose the joint pose in the child frame Default: the identity matrix
See also:
getChildPose()

virtual void PxArticulationJoint::setDamping ( PxReal  damping  )  [pure virtual]

set the damping of the joint acceleration spring

The acceleration generated by the spring drive is proportional to this value and the difference between the angular velocity of the joint and the target drive velocity.

Parameters:
[in] damping the damping of the joint drive Range: [0, PX_MAX_F32)
Default: 0.0

virtual void PxArticulationJoint::setExternalCompliance ( PxReal  compliance  )  [pure virtual]

get the drive external compliance

Compliance determines the extent to which the joint resists acceleration.
