LinearSpline

external class LinearSpline(options: LinearSpline.ConstructorOptions)(source)

A spline that uses piecewise linear interpolation to create a curve.

const times = [ 0.0, 1.5, 3.0, 4.5, 6.0 ];
const spline = new LinearSpline({
    times : times,
    points : [
        new Cartesian3(1235398.0, -4810983.0, 4146266.0),
        new Cartesian3(1372574.0, -5345182.0, 4606657.0),
        new Cartesian3(-757983.0, -5542796.0, 4514323.0),
        new Cartesian3(-2821260.0, -5248423.0, 4021290.0),
        new Cartesian3(-2539788.0, -4724797.0, 3620093.0)
    ]
});

const p0 = spline.evaluate(times[0]);

Properties

val points: ERROR CLASS: Symbol not found for ReadonlyArray<cesium/engine/Cartesian3>

Functions

fun clampTime(time: Double): Double

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

fun evaluate(time: Double, result: Cartesian3? = definedExternally): ERROR CLASS: Symbol not found for JsAny

Evaluates the curve at a given time.

findTimeInterval

fun findTimeInterval(time: Double): Int

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

fun wrapTime(time: Double): Double

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