		<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>代码示例</h2>

		<code>
		// 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 );
		</code>
