AVL.ShapeOrientation Method

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

Namespace:	AvlNet
Assembly:	AVL.NET.dll

Syntax

public static void ShapeOrientation(
	AvlNet.Path inShape,
	out float outOrientationAngle
)

Parameters

	Name	Type	Range	Default	Description
	inShape	AvlNet.Path
	outOrientationAngle	float

Description

Shape orientation can be thought of as the direction in which the shape is oriented. Mathematically it is the angle between X-axis and the line passing through the shape mass center, that rotation around this line produces the smallest torque.

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

Examples

Orientation of the sample region equals to 55.386, which is visualized on the second image by drawing the line of this orientation passing through the mass center of the shape.
