privatedelete

Assignment Operator not implemented – Copy not allowed.

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

virtual

Interrupt CullVisitors by updating the ribbon.

Reimplemented in makVrv::DtOsgTrackHistoryRibbon.

virtual osg::Node* makVrv::DtOsgRibbon::node ( )

virtual

Get the osg geometry node associated with the ribbon.

Reimplemented in makVrv::DtOsgMultiRibbon.

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

virtual

Set the ribbon's color.

Reimplemented in makVrv::DtOsgTrackHistoryRibbon.

virtual const osg::Vec4& makVrv::DtOsgRibbon::color ( void  ) const

inlinevirtual

Get the ribbon's color.

virtual void makVrv::DtOsgRibbon::setDroppedPoints ( const osg::Vec3d &  pointA, const osg::Vec3d &  pointB  )

virtual

Set the points to drop in local coordinates.

virtual void makVrv::DtOsgRibbon::setDroppedPointsPositionOffset ( const osg::Vec3d &  posOffset )

virtual

Provide an offset to the dropped points so the entity can shift around the points specified in the model definition ex. 5 ton truck can offset so front wheels leave tracks.

Reimplemented in makVrv::DtOsgMultiRibbon.

virtual void makVrv::DtOsgRibbon::update ( double  dt, double  simTime  )

virtual

Update the ribbon with the current position.

Reimplemented in makVrv::DtOsgMultiRibbon, and makVrv::DtOsgParticleRibbon.

virtual void makVrv::DtOsgRibbon::update ( )

virtual

Optional time independent update method.

nop for now

Reimplemented in makVrv::DtOsgTrackHistoryRibbon.

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

virtual

Sets the maximum number of segments allowed in the ribbon.

Reimplemented in makVrv::DtOsgTrackHistoryRibbon.

virtual long makVrv::DtOsgRibbon::maxSegments ( ) const

inlinevirtual

Gets the maximum number of segments allowed in the ribbon.

virtual void makVrv::DtOsgRibbon::setSegmentSpacing ( float  spacing )

virtual

Sets the maximum length of ribbon segments.

virtual void makVrv::DtOsgRibbon::setSegmentTimeout ( float  duration )

virtual

Sets the timeout of a ribbon segment.

virtual float makVrv::DtOsgRibbon::segmentSpacing ( ) const

inlinevirtual

Gets the maximum length of the ribbon segments.

virtual void makVrv::DtOsgRibbon::setStippled ( bool  stippled )

virtual

Parameters

[in]

stippled

is a flag to use a stipple pattern instead of alpha blending. When true, the ribbon is considered opaque and the stipple pattern allows see through. When false, the ribbon is considered transparent and alpha blending allows see through.

virtual bool makVrv::DtOsgRibbon::isStippled ( ) const

inlinevirtual

Get the stipple setting for this ribbon.

Return values

true	if stippled.
false	otherwise.
