PathPathIntersections

Header:	AVL.h
Namespace:	avl
Module:	FoundationPro

Computes the common points of two paths.

Syntax

void avl::PathPathIntersections
(
	const avl::Path& inPath1,
	const avl::Path& inPath2,
	atl::Array<avl::Point2D>& outIntersectionPoints,
	atl::Optional<atl::Array<int>&> outSegmentIndices1 = atl::NIL,
	atl::Optional<atl::Array<int>&> outSegmentIndices2 = atl::NIL
)

Parameters

Name	Type	Default	Description
inPath1	const Path&		Input path
inPath2	const Path&		Input path
outIntersectionPoints	Array<Point2D>&		Intersections between the input paths
outSegmentIndices1	Optional<Array<int>&>	NIL	Indices of the segments of the first path which generate found intersection points
outSegmentIndices2	Optional<Array<int>&>	NIL	Indices of the segments of the second path which generate found intersection points

Optional Outputs

The computation of following outputs can be switched off by passing value atl::NIL to these parameters: outSegmentIndices1, outSegmentIndices2.

Description

The operation computes an array of the intersection points of two given paths.

Examples

PathPathIntersections run on the sample paths. The resulting outIntersectionPoints were drawn onto the input paths.
