		float	segmentSpacing,
		const osg::Vec4 &	color,
		float	maxLength,
		float	timeout
	)

protected

CTOR (create through DtOsgDecalRibbonCreator method)

Parameters

de	the DtDe the ribbon belongs to.
segmentSpacing	the spacing between segments (in meters).
color	the color of the ribbon.
maxLength	the max length of the ribbon (in segments).

virtual makVrv::DtOsgTrackHistoryRibbon::~DtOsgTrackHistoryRibbon ( )

Member Function Documentation

DtOsgTrackHistoryRibbon& makVrv::DtOsgTrackHistoryRibbon::operator= ( const DtOsgTrackHistoryRibbon & )

privatedelete

Assignment Operator not implemented � Copy not allowed.

virtual void makVrv::DtOsgTrackHistoryRibbon::traverse ( osg::NodeVisitor & nv )

overridevirtual

Override default traverse to remove update behavior.

Reimplemented from makVrv::DtOsgRibbon.

virtual void makVrv::DtOsgTrackHistoryRibbon::setMaxSegments ( long segments )

overridevirtual

Sets the max number of segments in the ribbon.

Overridden from DtOsgRibbon to destroy the ribbon geometry and force re-creation when the max segment count changes.

Reimplemented from makVrv::DtOsgRibbon.

virtual void makVrv::DtOsgTrackHistoryRibbon::addParticle	(	osg::Vec3d const &	left,
		osg::Vec3d const &	right,
		double	simTime
	)

protectedvirtual

Add a particle to the ribbon.

Implements makVrv::DtOsgRibbon.

virtual float makVrv::DtOsgTrackHistoryRibbon::currentSegmentLength ( )

protectedvirtual

Find the length of the current ribbon segment.

Implements makVrv::DtOsgRibbon.

virtual void makVrv::DtOsgTrackHistoryRibbon::extendCurrentSegment	(	osg::Vec3d const &	left,
		osg::Vec3d const &	right,
		double	simTime
	)

protectedvirtual

Extend the current segment to left and right points.

Implements makVrv::DtOsgRibbon.

virtual void makVrv::DtOsgTrackHistoryRibbon::cleanupOldSegments ( double simTime )

protectedvirtual

Check to see if any segments have reached their timeout if so remove them from the list to be rendered.

currently only implemented for track histories.

Implements makVrv::DtOsgRibbon.

Reimplemented in makVrf::DtVrfOsgTrackHistoryRibbon.

virtual osg::Drawable* makVrv::DtOsgTrackHistoryRibbon::getDrawable ( )

protectedvirtual

Create or get the ribbon drawable.

Overridden from DtOsgRibbon to create the ribbon geometry.

Returns: the ribbon geometry (creating it on first call).

Implements makVrv::DtOsgRibbon.

virtual int makVrv::DtOsgTrackHistoryRibbon::particleIndexAtOffset ( int offset )

protectedvirtual

Get index of particle at offset from current particle.

virtual void makVrv::DtOsgTrackHistoryRibbon::update ( )

overrideprotectedvirtual

Calls DtOsgRibbon::update(double,double).

Passes zero for dt and de.simulationTime as parameters

Reimplemented from makVrv::DtOsgRibbon.

virtual void makVrv::DtOsgTrackHistoryRibbon::setColor ( const osg::Vec4 & color )

protectedvirtual

Change the geometry color.

Reimplemented from makVrv::DtOsgRibbon.

virtual void makVrv::DtOsgTrackHistoryRibbon::updateBounds ( const osg::Vec3 & point )

protectedvirtual

Update the ribbon's bounding box with a new point.

This is usually cheap, but at random intervals will do a full re-computation of the bounds, which costs O(# points).
