vue中threejs在地图上添加飞线

要在Vue中使用Three.js在地图上添加飞线，你需要按照以下步骤：

1. 首先，在Vue项目中安装Three.js。你可以使用npm或yarn来安装：

npm install three --save

或者

yarn add three

2. 在Vue组件中引入Three.js：

import * as THREE from 'three';

3. 创建一个Three.js场景并设置相机：

const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.z = 5;

4. 创建一个Three.js渲染器并将其添加到DOM中：

const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

5. 创建一个Three.js几何体和材质：

const geometry = new THREE.CylinderGeometry(0.1, 0.1, 1, 32);
const material = new THREE.MeshBasicMaterial({ color: 0xffffff });
const mesh = new THREE.Mesh(geometry, material);
scene.add(mesh);

6. 创建一个Three.js线条：

const points = [];
points.push(new THREE.Vector3(-10, 0, 0));
points.push(new THREE.Vector3(0, 10, 0));
points.push(new THREE.Vector3(10, 0, 0));

const geometry = new THREE.BufferGeometry().setFromPoints(points);
const material = new THREE.LineBasicMaterial({ color: 0xffffff });
const line = new THREE.Line(geometry, material);
scene.add(line);

7. 渲染场景：

function animate() {
    requestAnimationFrame(animate);
    mesh.rotation.x += 0.01;
    mesh.rotation.y += 0.01;
    renderer.render(scene, camera);
}
animate();

这是一个简单的示例，它向场景中添加了一个圆柱体和一条线条。你可以将其扩展为添加多条线条，并在地图上创建复杂的飞线动画。
