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.

bool osgUtil::SceneView::projectObjectIntoWindow ( const osg::Vec3 & object,

osg::Vec3 & window

) const

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. 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, via glUnProject, the object coordinates of a window point.

int y,

osg::Vec3 & near_point,

osg::Vec3 & far_point

) const

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

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

)

Set to a perspective projection.
See OpenGL glFrustum documentation for further details.

void osgUtil::SceneView::setProjectionMatrixAsOrtho ( double left,

double right,

double bottom,

double top,

double zNear,

double zFar

)

Set to an orthographic projection.
See OpenGL glOrtho for documentation further details.

void osgUtil::SceneView::setProjectionMatrixAsOrtho2D ( double left,

double right,

double bottom,

double top

)

Set to a 2D orthographic projection.
See OpenGL glOrtho2D documentation for further details.

void osgUtil::SceneView::setProjectionMatrixAsPerspective ( double fovy,

double aspectRatio,

double zNear,

double zFar

)

Create a symmetrical perspective projection, See OpenGL gluPerspective documentation for further details.
Aspect ratio is defined as width/height.

void osgUtil::SceneView::setRedrawInterlacedStereoStencilMask ( bool flag ) [inline]

Mannually set the redraw interlaced stereo stencil mask request flag to control whether to redraw the stencil buffer on the next frame.

void osgUtil::SceneView::setRenderStage ( osgUtil::RenderStage * rs ) [inline]

void osgUtil::SceneView::setRenderStageLeft ( osgUtil::RenderStage * rs ) [inline]

void osgUtil::SceneView::setRenderStageRight ( osgUtil::RenderStage * rs ) [inline]

void osgUtil::SceneView::setSceneData ( osg::Node * node )

Set the view matrix.
Can be thought of as setting the position of the world relative to the camera in camera coordinates.

void osgUtil::SceneView::setViewMatrixAsLookAt ( const osg::Vec3 & eye,

const osg::Vec3 & center,

const osg::Vec3 & up

)

Set to the position and orientation of view matrix, using the same convention as gluLookAt.

void osgUtil::SceneView::setViewport ( int x,

int y,

int width,

int height

) [inline]

Set the viewport of the scene view to specified dimensions.
