Member Function Documentation

virtual void makVrv::DtOsgTrackHistoryRibbon::traverse

(

osg::NodeVisitor &

nv

)

[virtual]

Override default traverse to remove update behavior.

Reimplemented from makVrv::DtOsgRibbon.

virtual void makVrv::DtOsgTrackHistoryRibbon::setMaxSegments

(

long

segments

)

[virtual]

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
	)		[protected, virtual]

Add a particle to the ribbon.

Implements makVrv::DtOsgRibbon.

virtual float makVrv::DtOsgTrackHistoryRibbon::currentSegmentLength

(

)

[protected, virtual]

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
	)		[protected, virtual]

Extend the current segment to left and right points.

Implements makVrv::DtOsgRibbon.

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

(

)

[protected, virtual]

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

)

[protected, virtual]

Get index of particle at offset from current particle.

virtual void makVrv::DtOsgTrackHistoryRibbon::update

(

)

[protected, virtual]

Calls DtOsgRibbon::update(double,double).

Passes zero for both parameters (dt and simTime).

Reimplemented from makVrv::DtOsgRibbon.

virtual void makVrv::DtOsgTrackHistoryRibbon::setColor

(

const osg::Vec4 &

color

)

[protected, virtual]

Change the geometry color.

Reimplemented from makVrv::DtOsgRibbon.
