	DtInstancedLightPointUpdate (osgSim::LightPoint lp, osg::ref_ptr< osgSim::LightPointNode > lpn, osg::Geometry *geom)
	Constructor: stores the lightpoint and lightpointnode associated with this object there is one of these updates for each light point on instanced geometry.
bool	isShadowCamera (osg::RenderInfo renderInfo) const
	checks to see if this render info is for a shadow camera. This is used to not draw instanced light points when it is a shadow camera
virtual bool	isSmallFeature (const osg::Matrixf &drawableMatrix, osg::ref_ptr< osg::Camera > camera)
	Check to see if this instance of the drawable is smaller than the small feature culling pixel size.
virtual bool	processSector (const osg::Matrixd &drawableMatrix)
	Check to see if the camera location is such that this light point should be drawn based on the light point's sector.
virtual bool	update (double frameTime, osg::Drawable *drw)
	Update callback for the geometry. Handles blinking lights and sets up the arrays for the geometry.
virtual void	setDaylightControlled (bool b)
	Set whether the light point visibility is controlled by daylight level.
virtual bool	daylightControlled ()
	Get whether light point visibility is controlled by daylight level.
