PolygonEllipticAxes


Module: FoundationBasic

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

Name Type Description
Input value inPolygon Path
Output value outMajorAxis Segment2D
Output value outMinorAxis 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.
