AlphaShape

class AlphaShape(val points: List<Vector2>)(source)

Class for creating alpha shapes. See the createContour and createShape methods to create an alpha shape.

Parameters

points

The points for which an alpha shape is calculated.

Constructors

AlphaShape

constructor(points: List<Vector2>)

Properties

delaunay

val delaunay: Delaunay

points

val points: List<Vector2>

Functions

createContour

fun createContour(): ShapeContour

Returns a closed ShapeContour representing an alpha shape without holes; the smallest alpha is chosen such that the corresponding alpha shape contains all input points and can be represented by a closed ShapeContour.

fun createContour(alpha: Double): ShapeContour

Creates an alpha shape without holes

createSegments

fun createSegments(alpha: Double): List<LineSegment>

Creates an alpha shape

createShape

fun createShape(): Shape

Returns a Shape representing an alpha shape; the smallest alpha is chosen such that the corresponding alpha shape contains all input points and can be represented by a Shape (in particular, it consists of one component).

fun createShape(alpha: Double): Shape

Creates an alpha shape, possibly with holes

determineContourAlpha

fun determineContourAlpha(): Double
