Detailed Description

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.

Reimplemented from osg::CullSettings.

virtual void osgUtil::SceneView::init ( ) [virtual]

Do init traversal of attached scene graph using Init NodeVisitor.

The init traversal is called once for each SceneView, and should be used to compile display list, texture objects intialize data not otherwise intialized during scene graph loading. Note, is called automatically by update & cull if it hasn't already been called elsewhere. Also init() should only ever be called within a valid graphics context.

osgUtil::SceneView::META_Object ( osgUtil  ,
SceneView   
)
bool osgUtil::SceneView::projectObjectIntoWindow ( const osg::Vec3 object,
osg::Vec3 window 
) 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. Consistent with OpenGL windows coordinates are calculated relative to the bottom left of the window, whereas window API's normally have the top left as the origin, so you may need to pass in (mouseX,window_height-mouseY,...). Returns true on successful projection.

bool osgUtil::SceneView::projectWindowIntoObject ( const osg::Vec3 window,
osg::Vec3 object 
) const

Calculate the object coordinates of a point in window coordinates.

Note, current implementation requires that SceneView::draw() has been previously called for projectWindowIntoObject to produce valid values. Consistent with OpenGL windows coordinates are calculated relative to the bottom left of the window. Returns true on successful projection.

bool osgUtil::SceneView::projectWindowXYIntoObject ( int  x,
int  y,
osg::Vec3 near_point,
osg::Vec3 far_point 
) const

Calculate 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. Consistent with OpenGL windows coordinates are calculated relative to the bottom left of the window. Returns true on successful projection.
