Hi Monia,
You have several options open to you:
1) Write a custom CameraManipulator along the lines of one of the
existing ones in src/osgGA
2) Not use a CameraManipulator on the view and use a Camera update
callback to set the ViewMatrix
once per frame
3) Set the Camera's ViewMatrix directly within the frame loop i.e.
expand viewer.run() out into:
// note, don't assign a CameraManipulator
viewer.realize();
while(!viewer.done())
{
// your code for computing myViewMatrix
viewer.getCamera()->setViewMatrix(myViewMatrix);
viewer.frame();
}
or with frame itself expanded
// note, don't assign a CameraManipulator
viewer.realize();
while(!viewer.done())
{
// your code for computing myViewMatrix
viewer.advance();
viewer.eventTraversal();
viewer.updateTraversal();
viewer.getCamera()->setViewMatrix(myViewMatrix);
viewer.renderingTraversals();
}
