# 样条曲线（[name]）

从一系列的点中，创建一个平滑的二维样条曲线。内部使用[page:Interpolations.CatmullRom]来创建曲线。

## 代码示例

`// Create a sine-like wave const curve = new THREE.SplineCurve( [ new THREE.Vector2( -10, 0 ), new THREE.Vector2( -5, 5 ), new THREE.Vector2( 0, 0 ), new THREE.Vector2( 5, -5 ), new THREE.Vector2( 10, 0 ) ] ); const points = curve.getPoints( 50 ); const geometry = new THREE.BufferGeometry().setFromPoints( points ); const material = new THREE.LineBasicMaterial( { color: 0xff0000 } ); // Create the final object to add to the scene const splineObject = new THREE.Line( geometry, material );`

## 构造函数

### [name]( [param:Array points] )

points – 定义曲线的[page:Vector2]点的数组。

## 属性

共有属性请参见其基类[page:Curve]。

### [property:Array points]

定义这一曲线的[page:Vector2]点的数组。

## 方法

共有方法请参见其基类[page:Curve]。
