Hi Peter,
I presume what you are up against is the use of a Camera Manipulator
that is setting the viewer's Camera's View Matrix on each frame.
If you don't want the standard manipulator then don't register one,
and instead set the view matrix on each frame i.e
viewer.realize();
while(!viewer.done())
{
osg::Matrixd myViewMatrix = ....; // compute in some way.
viewer.getCamera()->setViewMatrix(myViewMatrx);
viewer.frame();
}
Or alternatively you could just set the home position of the camera manipulator.
