Hi Alexey, Use getCamera()->getViewMartix*() methods is the appropriate thing to do. You might want to split the viewer.frame() into it's constituent parts to make sure that you can the view matrix that is appropriate for the frame you are working on - the viewer.updateTraversal() method updates the view matrix on each frame. Have a look at the source to viewer.frame() to see what it's made from.
