What you simply have to do is to apply the transformation in the local
coordinate system of the Viewplatform. So you do the following:
coordinate transformation to local coordinate system -> applying your
transformation matrix -> coordinate transformation back to
virtual coordinate system. Watch order of matrix muliplication.
myViewplatform . getLocalToVworld( vpTransform );
vpTransform . getRotationScale( itsTempMatrix );
vpTransform . set( itsTempMatrix );
itsTempMatrix.transpose();
tempTransform .set( itsTempMatrix );
tempTransform . mul( myTransform, itsTempTransform );
vpTransform . mul( tempTransform );
// now apply vpTransform to your Viewplatformtransformgroup

PS: Just for completion: this does not take any Userhead tranformations.
