如何在three.js中绘制多段线？

// 创建场景
var scene = new THREE.Scene();

// 创建相机
var camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.z = 5;

// 创建渲染器
var renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

// 创建多段线的顶点坐标数组
var points = [];
points.push(new THREE.Vector3(-2, 0, 0));
points.push(new THREE.Vector3(0, 2, 0));
points.push(new THREE.Vector3(2, 0, 0));
points.push(new THREE.Vector3(0, -2, 0));

// 创建多段线的材质
var material = new THREE.LineBasicMaterial({ color: 0x00ff00 });

// 创建多段线的几何体
var geometry = new THREE.BufferGeometry().setFromPoints(points);

// 创建多段线对象
var line = new THREE.LineSegments(geometry, material);
// 或者使用下面的代码创建闭合的多段线
// var line = new THREE.LineLoop(geometry, material);

// 将多段线添加到场景中
scene.add(line);

// 渲染循环
function animate() {
    requestAnimationFrame(animate);
    line.rotation.x += 0.01;
    line.rotation.y += 0.01;
    renderer.render(scene, camera);
}
animate();
