Detailed Description

OverlayNode is for creating texture overlays on scenes, with the overlay texture being generated by pre rendering an Overlay Subgraph to a texture, then projecting this resulting texture on the scene.

		OverlayNode	)

References OverlayNode().

releaseGLObjects()

virtual void osgSim::OverlayNode::releaseGLObjects ( osg::State * = 0 ) const

virtual

If State is non-zero, this function releases any associated OpenGL objects for the specified graphics context. Otherwise, releases OpenGL objexts for all graphics contexts.

Reimplemented from osg::Group.

resizeGLObjectBuffers()

virtual void osgSim::OverlayNode::resizeGLObjectBuffers ( unsigned int )

virtual

Resize any per context GLObject buffers to specified size.

Reimplemented from osg::Group.

setContinuousUpdate()

void osgSim::OverlayNode::setContinuousUpdate ( bool update )

inline

Set whether the OverlayNode should update the overlay texture on every frame.

References _continuousUpdate.

setOverlayBaseHeight()

void osgSim::OverlayNode::setOverlayBaseHeight ( double baseHeight )

inline

Set the base height that the overlay subgraph will be projected down to. Normally you'll set this to just below ground level, if you set it too high then the overlay texture can end up being clipped in certain viewing directions, while if its too low then there will be a limit to how close you can get to the terrain before pixaltion becomes an issue.

References _overlayBaseHeight.

inline

Set the clear color to use when rendering the overlay subgraph.
