AVL.PolygonEllipticAxes

Computes axes of an ellipse having the same first and second order moments as the given polygon.

Namespace:AvlNet
Assembly:AVL.NET.dll

Syntax

C++
C#
 
public static void PolygonEllipticAxes
(
	AvlNet.Path inPolygon,
	out AvlNet.Segment2D outMajorAxis,
	out AvlNet.Segment2D outMinorAxis
)

Parameters

Name Type Range Default Description
inPolygonAvlNet.Path
outMajorAxisAvlNet.Segment2D
outMinorAxisAvlNet.Segment2D

Description

The orientations of the resulting axes are always between 0 and 180 degrees.

Note that if the input path is not a valid polygon (i.e. it has at least one self-intersection), the computation may lead to results that are not intuitive.

Errors

List of possible exceptions:

Error type Description
DomainError Degenerate polygon on input in PolygonEllipticAxes.
