btConeTwistConstraint / 6DofConstraint orientation

[mickey]

Hi

the btHingleConstraints have a getHingeAngle() method, that I can use to properly orient my rigid body / rag doll, this way, I can easily orient the knee and elbow joints.

Other joints of the body however uses either the cone twist or the 6-dof. I was wondering how do i get the orientation properly here so I can also apply them to my mesh.

Thanks.
