[name]

Create a smooth 3d spline curve from a series of points using the [link:https://en.wikipedia.org/wiki/Centripetal_Catmull-Rom_spline Catmull-Rom] algorithm.

Example

//Create a closed wavey loop var 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) ]); var points = curve.getPoints(50); var geometry = new v3d.BufferGeometry().setFromPoints(points); var material = new v3d.LineBasicMaterial({ color : 0xff0000 }); // Create the final object to add to the scene var curveObject = new v3d.Line(geometry, material);

Constructor

[name]([param:Array points], [param:Boolean closed], [param:String curveType], [param:Float tension])

points – An array of [page: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 [page:Curve] class for common properties.

[property:Boolean isCatmullRomCurve3]

Used to check whether this or derived classes are CatmullRomCurve3s. Default is *true*.

You should not change this, as it used internally for optimisation.

[property:Array points]

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

[property:Boolean closed]

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

[property:String curveType]

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

[property:float tension]

When [page:.type] is *catmullrom*, defines catmullrom's tension.

Methods

See the base [page:Curve] class for common methods.
