Curve

CurvePath

An abstract base class extending Curve. A CurvePath is simply an array of connected curves, but retains the api of a curve.

Constructor

CurvePath()

The constructor take no parameters.

Properties

See the base Curve class for common properties.

.curves : Array

The array of Curves.

.autoClose : Boolean

Whether or not to automatically close the path.

Methods

See the base Curve class for common methods.

.add (curve : Curve) : null

Add a curve to the .curves array.

.closePath () : null

Adds a lineCurve to close the path.

.getCurveLengths () : Array

Get list of cumulative curve lengths of the curves in the .curves array.

.getPoint (t : Float) : Vector

t - A position on the curve. Must be in the range [0, 1].

Returns a vector for a given position on the curve path.

.getPoints (divisions : Integer) : Array

divisions -- number of pieces to divide the curve into. Default is 12.

Returns an array of points representing a sequence of curves. The division parameter defines the number of pieces each curve is divided into. However, for optimization and quality purposes, the actual sampling resolution for each curve depends on its type. For example, for a LineCurve, the returned number of points is always just 2.

.getSpacedPoints (divisions : Integer) : Array

divisions -- number of pieces to divide the curve into. Default is 40.

Returns a set of divisions + 1 equi-spaced points using getPointAt(u).
