AVL.ShapeConvexity Method
Computes the area of a shape divided by the area of its convex hull.
Namespace: | AvlNet |

Assembly: | AVL.NET.dll |
Syntax
public static void ShapeConvexity( AvlNet.Path inShape, out float outConvexity )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inShape | AvlNet.Path | ||||
outConvexity | float |
Description
Convexity is a measure of how close a shape is to being convex. Convex shapes have convexity equal to 1.0, while the more concave the shape is, the closer to 0.0 is its convexity.
Mathematically, the convexity is calculated as follows:
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.
