Hi Diana,
If you are controlling the camera from a user defined path or
simulation then you are best to not attach a camera manipulator to the
viewer and just set the viewer's master camera directly yourself. If
you do try to set the camera's view matrix yourself but still have a
camera manipualtor attached the value you set will be overwritten.
The osgViewer::Viewer by default will not attach a camera manipulator,
but if you call viewer.run() it will know assume there isn't anything
else settings the view matrix so will attach a camera manipulator as a
fallback to at least provide some interactive view.
For your own app I'd expect something like:
osgViewer::Viewer viewer;
viewer.setSceneDat(mySceneGraph);
viewer.realize();
while(!viewer.done())
{
viewer.getCamera()->setViewMatrix(myViewMatrix); // or use
setViewMatrixAsLookAt(..)
viewer.frame();
}
Robert.
