三维二次贝塞尔曲线（[name]）

创建一条平滑的三维二次贝塞尔曲线，由起点、终点和一个控制点所定义。

代码示例


		const curve = new THREE.QuadraticBezierCurve3(
			new THREE.Vector3( -10, 0, 0 ),
			new THREE.Vector3( 20, 15, 0 ),
			new THREE.Vector3( 10, 0, 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 curveObject = new THREE.Line( geometry, material );
