PathDiameter
Finds the longest segment connecting two characteristic points of a path.
Syntax
C++
C#
void avl::PathDiameter
(
const avl::Path& inPath,
atl::Optional<avl::Segment2D&> outDiameter,
atl::Optional<float&> outDiameterLength
)
void PathDiameter
(
Path inPath,
out Segment2D? outDiameter,
out float? outDiameterLength
)
Parameters
Description
The operation finds the most distant pair of points within a path and returns the distance between them (outDiameterLength) and the segment representing the diameter (outDiameter). If there is more than one pair of maximal distance, the returned segment will correspond to one of them. The orientation of the resulting outDiameter is always between 0 and 180 degrees.
Examples
The resulting outDiameterLength = 280.0921, outDiameter segment was drawn onto the sample path.
