Zoom in ortho is done by shrinking or expanding the view volume
defined by the left right top bottom planes.

I'm calling osg::Camera::setProjectionMatrixAsOrtho() and I'm
getting an
orthographic projection (this is, if I look directly at the face of a
cube in wireframe, all I see is a square). I can rotate and pan, but
zoom isn't working (I'm dragging the right mouse button).
I want to allow the user to toggle between perspective and
orthographic
projections. Obviously I need to do more than just set the projection
matrix, but I'm not sure where to start looking for clues. I've been
searching on setProjectionMatrixAsOrtho. What should I be looking for?
Thanks,
