Computes the polygon orientation as angle with value in range 0.0 - 180.0.

Assembly: | AVL.NET.dll |
Syntax

public static void PolygonOrientation ( AvlNet.Path inPolygon, out float outOrientationAngle )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inPolygon | AvlNet.Path | ||||
outOrientationAngle | float |
Description
Polygon orientation can be thought of as the direction in which the polygon is oriented. Mathematically it is the angle between X-axis and the line passing through the polygon mass center, that rotation around this line produces the smallest torque.
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.
