| Calculate, via glProject, the object coordinates of a window. Note, current implementation requires that SceneView::draw() has been previously called for projectWindowIntoObject to produce valid values.

Returns true on successful projection.

|  | osg::Vec3 & | object
| ) | const

|  | osg::Vec3 & | far_point

| Calculate, via glUnProject, the object coordinates of a window x,y when projected onto the near and far planes. Note, current implementation requires that SceneView::draw() has been previously called for projectWindowIntoObject to produce valid values.
