		<h1>样条曲线（[name]）</h1>

		<p class="desc">
			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。
		</p>

		<h2>示例</h2>

<code>
// Create a sine-like wave
var 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 )
] );

var points = curve.getPoints( 50 );
var geometry = new THREE.BufferGeometry().setFromPoints( points );

var material = new THREE.LineBasicMaterial( { color : 0xff0000 } );

// Create the final object to add to the scene
var splineObject = new THREE.Line( geometry, material );
</code>

		<h2>构造函数</h2>


		<h3>[name]( [param:Array points] )</h3>
		<p>points – 定义曲线的[page:Vector2]点的数组。</p>


		<h2>属性</h2>
		<p>共有属性请参见其基类[page:Curve]。</p>

		<h3>[property:Boolean isSplineCurve]</h3>
		<p>
			用于检查该类或者其派生类是否为样条曲线。默认值为*true*。<br /><br />

			你不应当对这一属性进行改变，它在内部使用，以用于优化。
		</p>

		<h3>[property:Array points]</h3>
		<p>定义这一曲线的[page:Vector2]点的数组。</p>


		<h2>方法</h2>
		<p>共有方法请参见其基类[page:Curve]。</p>
