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

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

Intersects(IList<ISegmentString>)

Tests for intersections with a given set of target ISegmentStrings.

Declaration

public bool Intersects(IList<ISegmentString> segStrings)

Parameters

Type	Name	Description
IList<ISegmentString>	segStrings	The SegmentStrings to test

Returns

Type	Description
Boolean	true if an intersection was found

Intersects(IList<ISegmentString>, SegmentIntersectionDetector)

Declaration

public bool Intersects(IList<ISegmentString> segStrings, SegmentIntersectionDetector intDetector)

Parameters

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

Returns

Type	Description
Boolean	true if the detector reports intersections
