I realized that is possible to attach a MatrixManipulator to a specific
node, for example the one that I want to zoom on.
So, I can handle some events (key down for example), and if I call the
MatrixManipulator::home() method after having attached the node to the
manipulator, then I manage to
Hi,
I think the problem here is that some manipulators take the bounding box
of the scenegraph to calculate the home position. Setting the nodemask
to zero will not affect the bounding box, so the whole hierarchy is
still regarded.
One solution may be to fully detach the invisible node from the
Hello!
I would overwrite the manipulator's way of home position calculation to only
consider visible objects. By doing this you can basically test for
whatever attributes you like on the nodes. It would also mean small,
non-intrusive changes which can easily be reused and/or modified for
Hello,
using osgViewer, I see that pressing the spacebar the view is restored in
order tor frame all the objects in the scene... I also noticed that it
adjusts the camera in order to consider also objects that are not visible...
how can I change this behaviour in order to frame just visible
Hi Alessandro,
The space bar is call home on the manipulator, and this takes the
manipulators position to its home position, which you can set via...
setHomePosition(,,);

Hello!
The spacebar event is simply setting the camera to the camera
manipulator's home position. It does not modify your scenegraph, although it
might appear that way. The home position is either calculated (default) or
set using an eye and center coordinate along with the definition of up.
Hi Alessandro,
The OSG can't guess at all the different ways that you might want to
set up the home position using automatic code, the default code for
setting the position does OK for most models, but if you need
something better tailored to your specific application needs then you
need to
