CatmullRomCurve3

Create a smooth 3D spline curve from a series of points using the Catmull-Rom algorithm.

Code Example


    // create a closed wavey loop
    const curve = new v3d.CatmullRomCurve3([
        new v3d.Vector3(-10, 0, 10),
        new v3d.Vector3(-5, 5, 5),
        new v3d.Vector3(0, 0, 0),
        new v3d.Vector3(5, -5, 5),
        new v3d.Vector3(10, 0, 10)
    ]);

    const points = curve.getPoints(50);
    const geometry = new v3d.BufferGeometry().setFromPoints(points);

    const material = new v3d.LineBasicMaterial({ color: 0xff0000 });

    // create the final object to add to the scene
    const curveObject = new v3d.Line(geometry, material);

Constructor

CatmullRomCurve3(points : Array, closed : Boolean, curveType : String, tension : Float)

points – An array of Vector3 points
closed – Whether the curve is closed. Default is false.
curveType – Type of the curve. Default is "centripetal".
tension – Tension of the curve. Default is 0.5.

Properties

See the base Curve class for common properties.

# .points : Array

The array of Vector3 points that define the curve. It needs at least two entries.

# .closed : Boolean

The curve will loop back onto itself when this is true.

# .curveType : String

Possible values are "centripetal", "chordal", and "catmullrom".

# .tension : Float

When .curveType is "catmullrom", defines catmullrom's tension.

Methods

See the base Curve class for common methods.
