Hi Vincent,
When I set the PAT as Tracked node... is PAT is rotated and
translated... camera do not follow it...
Does your PAT have geometry under it? Or is it just a PAT in space
without any children?
We had a problem like that before, where if a transform (for us it was
an osgSim::DOFTransform) had no geometry under it, it could not be
followed by a NodeTrackerManipulator. The reason is that the NTM uses
the node's bounds to calculate where it should track, and a Transform
without anything under it has invalid bounds (a default-constructed
bounding sphere with radius = -1).
What we did to fix it is to add a ComputeBoundingSphereCallback to the
transform, which returns a bounding sphere of center =
(transform.translation) and radius = 0.1. That makes the NTM behave
properly.
Not sure if that's your problem. If it isn't then I don't know, your
code looks good. If you send me a complete example (perhaps a modified
osgviewer.cpp with your code) I could have a look.
