In OSG 1.0, in the osgkeyboardmouse example, I was able to override the
mouse control view functionality by
by replacing this line:
// set the view
sceneView->setViewMatrix(kbmcb->getViewMatrix());
With my own calculated matrix based on the kbmcb values.
In version 2.0 osgkeyboardmouse example, it looks like
all the mouse functionality for the view resides in the following line:
// create a tracball manipulator to move the camera around in response
to keyboard/mouse events
viewer.setCameraManipulator( new osgGA::TrackballManipulator );
Which I would like to replace with my functionality. I tried creating
a GUIEventHandler Class and adding it as EventHandler to my view, (just
like the PickHandler class)
but when I try to remove the following line:
viewer.setCameraManipulator( new osgGA::TrackballManipulator );
I don't see anything in my simulation.
What I think I should do next is create my own derived version of the
TrackballManipulaltor class and implement my mouse logic their.
Does this sound like the right thing to do? Is their a better way?
I'm also confused about the billboard examples ( and other examples
simular to it). Looks like they never added anytype of Manipulator to
the camera.
and I'm wondering how the camera manipulation is being done? Is their a
default manipulator that comes with the osgViewer::Viewer?
By the way OSG is awesome! Thanks for all the hardwork.
