Spline

abstract external class Spline(source)

Creates a curve parameterized and evaluated by time. This type describes an interface and is not intended to be instantiated directly.

Constructors

constructor()

An array of control points.

An array of times for the control points.

abstract fun clampTime(time: Double): Double

Clamps the given time to the period covered by the spline.

abstract fun evaluate(time: Double, result: Any? = definedExternally): Any

Evaluates the curve at a given time.

abstract fun findTimeInterval(time: Double, startIndex: Int): Int

Finds an index i in times such that the parameter time is in the interval [times[i], times[i + 1]].

abstract fun wrapTime(time: Double): Double

Wraps the given time to the period covered by the spline.
