Constructor & Destructor Documentation

makVrv::DtInstancedLightPointUpdate::DtInstancedLightPointUpdate	(	const osgSim::LightPoint &	lp,
		osgSim::LightPointNode *	lpn,
		osg::Geometry *	geom,
		DtDe &	de
	)

Constructor: stores the lightpoint and lightpointnode associated with this object there is one of these updates for each light point on instanced geometry.

Member Function Documentation

bool makVrv::DtInstancedLightPointUpdate::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 makVrv::DtInstancedLightPointUpdate::isSmallFeature ( const osg::Matrixf &  drawableMatrix, osg::ref_ptr< osg::Camera >  camera, float  lightMinPixelSize  )

virtual

Check to see if this instance of the drawable is smaller than the small feature culling pixel size.

virtual bool makVrv::DtInstancedLightPointUpdate::processSector ( const osg::Matrixd &  drawableMatrix )

virtual

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 makVrv::DtInstancedLightPointUpdate::update ( double  frameTime, osg::Drawable *  drw, double  lastShaderReload  )

virtual

Update callback for the geometry. Handles blinking lights and sets up the arrays for the geometry.

virtual void makVrv::DtInstancedLightPointUpdate::setDaylightControlled ( bool  b )

virtual

Set whether the light point visibility is controlled by daylight level.

virtual bool makVrv::DtInstancedLightPointUpdate::daylightControlled ( )

virtual

Get whether light point visibility is controlled by daylight level.

virtual osgSim::LightPointNode* const makVrv::DtInstancedLightPointUpdate::lightPointNode ( ) const

virtual

The light point node has values that apply to all instances of a given lightpoint node.
