Detailed Description

Based on osgUtil::SceneView, but stripped done to only render and not interfere with stereo setup.

SceneView is deprecated, and is now just kept for backwards compatibility. It is recommend that you use osgViewer::Viewer/Composite in combination with osgViewer::GraphicsWindowEmbedded for embedded rendering support as this provides a greater range of functionality and consistency of API.

) const

Calculate the window coordinates of a point in object coordinates.

Note, current implementation requires that SceneView::draw() has been previously called for projectWindowIntoObject to produce valid values.

Returns true on successful projection.
