PathPathIntersections

Computes the common points of two paths.

Header:	AVL.h

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
)

void PathPathIntersections
(
	Path inPath1,
	Path inPath2,
	out Point2D[] outIntersectionPoints,
	out int[] outSegmentIndices1,
	out int[] outSegmentIndices2
)

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

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.
