Detailed Description

DtIntersectNetworkSegmentMetric is a metric for segments in an mx-cif quadtree.

The metric is based on distance from a point.

DtIntersectNetworkSegmentMetric::DtIntersectNetworkSegmentMetric ( )

Default constructor.

virtual DtIntersectNetworkSegmentMetric::~DtIntersectNetworkSegmentMetric ( ) [virtual]

Destructor.

DtIntersectNetworkSegmentMetric::DtIntersectNetworkSegmentMetric ( const DtIntersectNetworkSegmentMetric & orig )

Copy constructor.

Member Function Documentation

DtIntersectNetworkSegmentMetric& DtIntersectNetworkSegmentMetric::operator= ( const DtIntersectNetworkSegmentMetric & orig )

Assignment operator.

virtual double DtIntersectNetworkSegmentMetric::measure ( const DtNetworkSegment & seg ) const [virtual]

Measure the specified segment.

Implements DtNetworkSegmentMetric.

virtual double DtIntersectNetworkSegmentMetric::measure	(	const DtNetworkSegment &	seg,
		DtPoint &	p
	)		const `[virtual]`

Parameters:

p	a reference to a point that is set to the point of intersection between this and the specified segment if one exists

virtual bool DtIntersectNetworkSegmentMetric::circumscribedSquareTest ( const DtNetworkSegment & seg ) const [virtual]

Quick check using the square circumscribing the circle around the center of interest.

virtual bool DtIntersectNetworkSegmentMetric::valid ( const DtNetworkSegment & seg ) const [virtual]

Validate the segment.

Implements DtNetworkSegmentMetric.

virtual bool DtIntersectNetworkSegmentMetric::validSW	(	double	xx,
		double	yy
	)		const `[virtual]`

Validate the southwest quadrant (closed on southwest side)

Implements DtNetworkSegmentMetric.

virtual bool DtIntersectNetworkSegmentMetric::validSE	(	double	xx,
		double	yy
	)		const `[virtual]`

Validate the southeast quadrant (closed on southwest side)

Implements DtNetworkSegmentMetric.

virtual bool DtIntersectNetworkSegmentMetric::validNE	(	double	xx,
		double	yy
	)		const `[virtual]`

Validate the northeast quadrant (closed on southwest side)

Implements DtNetworkSegmentMetric.

virtual bool DtIntersectNetworkSegmentMetric::validNW	(	double	xx,
		double	yy
	)		const `[virtual]`

Validate the northwest quadrant (closed on southwest side)

Implements DtNetworkSegmentMetric.

virtual const DtChord& DtIntersectNetworkSegmentMetric::centerOfInterest ( ) const [virtual]

get/set center of interest

virtual void DtIntersectNetworkSegmentMetric::setCenterOfInterest ( const DtChord & centerOfInterest ) [virtual]

virtual bool DtIntersectNetworkSegmentMetric::evalInZ ( ) [virtual]

get/set evaluation in Z

virtual void DtIntersectNetworkSegmentMetric::setEvalInZ ( bool eval ) [virtual]

virtual double DtIntersectNetworkSegmentMetric::maxRange ( ) const [virtual]

get/set Intersection range

virtual void DtIntersectNetworkSegmentMetric::setMaxRange ( double val ) [virtual]

virtual double DtIntersectNetworkSegmentMetric::measureMultiplier ( ) const [virtual]

get/set measure multiplier

virtual void DtIntersectNetworkSegmentMetric::setMeasureMultiplier ( double val ) [virtual]

virtual const DtTerrainDatabase* DtIntersectNetworkSegmentMetric::terrainDb ( ) [virtual]

get/set terrain database member

virtual void DtIntersectNetworkSegmentMetric::setTerrainDb ( const DtTerrainDatabase * db ) [virtual]

virtual void DtIntersectNetworkSegmentMetric::initialize ( Coordinate_System * cs ) [virtual]

Initialize the metric.

Use this call to do any additional preparation/initialization before the metric can be used. The vector network calls this function every time a metric is about to be used.
