Syntax

public class FastSegmentSetIntersectionFinder

Remarks

Uses indexing for fast performance and to optimize repeated tests against a target set of lines. Short-circuited to return as soon an intersection is found.

Immutable and thread-safe.

Constructors

FastSegmentSetIntersectionFinder(IEnumerable<ISegmentString>)

Creates an intersection finder against a given set of segment strings.

Declaration

public FastSegmentSetIntersectionFinder(IEnumerable<ISegmentString> baseSegStrings)

Parameters

Type	Name	Description
IEnumerable<ISegmentString>	baseSegStrings	The segment strings to search for intersections

FastSegmentSetIntersectionFinder(IEnumerable<ISegmentString>, ElevationModel)

Creates an intersection finder against a given set of segment strings.

Declaration

public FastSegmentSetIntersectionFinder(IEnumerable<ISegmentString> baseSegStrings, ElevationModel em)

Parameters

Type	Name	Description
IEnumerable<ISegmentString>	baseSegStrings	The segment strings to search for intersections
ElevationModel	em	An elevation model, may be null

Properties

SegmentSetIntersector

Gets the segment set intersector used by this class.

Declaration

public ISegmentSetMutualIntersector SegmentSetIntersector { get; }

Property Value

Type	Description
ISegmentSetMutualIntersector

Remarks

This allows other uses of the same underlying indexed structure.

Methods

Returns

Type	Description
bool	true if an intersection was found

Intersects(IList<ISegmentString>, SegmentIntersectionDetector)

Parameters

Type	Name	Description
IList<ISegmentString>	segStrings	The SegmentStrings to test
SegmentIntersectionDetector	intDetector	The intersection detector to use

Returns

Type	Description
bool	true if the detector reports intersections
