# [name]

Create a smooth 3d spline curve from a series of points that loops back onto itself. THREE.ClosedSplineCurve3 has been deprecated. Please use THREE.CatmullRomCurve3

## Example

`//Create a closed wavey loop var curve = new THREE.ClosedSplineCurve3( [ new THREE.Vector3( -10, 0, 10 ), new THREE.Vector3( -5, 5, 5 ), new THREE.Vector3( 0, 0, 0 ), new THREE.Vector3( 5, -5, 5 ), new THREE.Vector3( 10, 0, 10 ) ] ); var geometry = new THREE.Geometry(); geometry.vertices = curve.getPoints( 50 ); var material = new THREE.LineBasicMaterial( { color : 0xff0000 } );`
