PathSelfIntersections

Header:	FIL.h
Namespace:	fil
Module:	FoundationPro

Checks if a path has any self-intersections and computes all of them.

Syntax

void fil::PathSelfIntersections
(
	const fil::Path& inPath,
	ftl::Array<fil::Point2D>& outSelfIntersections,
	ftl::Optional<ftl::Array<int>&> outFirstSegmentIndices = ftl::NIL,
	ftl::Optional<ftl::Array<int>&> outSecondSegmentIndices = ftl::NIL,
	ftl::Optional<bool&> outIsSelfIntersecting = ftl::NIL
)

Parameters

Name	Type	Default	Description
inPath	const Path&		Input path
outSelfIntersections	Array<Point2D>&
outFirstSegmentIndices	Optional<Array<int>&>	NIL	First indices of the segments of the path which generate found intersection points
outSecondSegmentIndices	Optional<Array<int>&>	NIL	Second indices of the segments of the path which generate found intersection points
outIsSelfIntersecting	Optional<bool&>	NIL

Optional Outputs

The computation of following outputs can be switched off by passing value ftl::NIL to these parameters: outFirstSegmentIndices, outSecondSegmentIndices, outIsSelfIntersecting.
