AVL.ShapeElongation(AvlNet.Path, float)
| Namespace: | AvlNet |
|---|---|
| Assembly: | AVL.NET.dll |
Syntax
public static void ShapeElongation( AvlNet.Path inShape, out float outElongation )
Parameters
- inShape
- Type: AvlNet.Path
- outElongation
- Type: System.Single
Description
Elongation is a measure of how long the shape is in relation to its width. The perfect circle has the minimal elongation equal to 1.0, while the upper bound doesn't exist.
The operation internally approximates the shape with an ellipse, and then computes the result as:
Where L denotes the longer axis of the approximating ellipse, and S denotes the shorter one.
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
Elongation of the sample shape equals to 3.283. |
Elongation of the sample shape equals to 1.001. |
Errors
| Error type | Description |
|---|---|
| DomainError | Open path on input in ShapeElongation. |
| DomainError | Degenerate shape on input in ShapeElongation. |
