I was looking at the NPS tutorials and it was mentioned in tutorial

getMatrix() ) and while the camera follows the path of my node through space
as it moves (it is scripted), I don't see my node. I did set a minimum
Could someone either point me to a tutorial or give me a quick overview of
how to a TrackerManipulator? Ultimately I'm trying to make a camera I can
orbit around a moving vehicle, keeping focus on the vehicle (I presume some

Right now I'm manually calculating it using spherical coordinates,
retrieving the position of my target node, and using makeLookAt() to
generate a matrix.
