RegionOrientation
Computes the orientation of a region as an angle of value in range 0.0 - 180.0.
Syntax
C++
C#
void avl::RegionOrientation ( const avl::Region& inRegion, float& outOrientationAngle )
Parameters
| Name | Type | Default | Description | |
|---|---|---|---|---|
 |
inRegion | const Region& | Input region | |
 |
outOrientationAngle | float& |
Description
Region orientation can be thought of as the direction in which the region is oriented. Mathematically it is the angle between X-axis and the line passing through the region mass center, that rotation around this line produces the smallest torque.
Hints
- If the input region is not guaranteed to be non-empty, precede this filter with SkipEmptyRegion.
Examples

Orientation of the sample region equals to 53.496, which is visualized on the second image by drawing the line of this orientation passing through the region mass center.
