three.js+vue实现酷炫三维地图web3d大屏可视化GIS地图

以下是一个简化的代码示例，展示了如何在Vue组件中集成Three.js来创建一个基本的3D地图可视化：

<template>
  <div ref="threeContainer"></div>
</template>
 
<script>
import * as THREE from 'three';
import { OrbitControls } from 'three/examples/jsm/controls/OrbitControls.js';
import { GLTFLoader } from 'three/examples/jsm/loaders/GLTFLoader.js';
import { RGBELoader } from 'three/examples/jsm/loaders/RGBELoader.js';
 
export default {
  name: 'ThreeDMap',
  mounted() {
    this.initThreeJS();
    this.loadEnvironmentMap();
    this.loadModel();
    this.addControls();
    this.animate();
  },
  methods: {
    initThreeJS() {
      const width = this.$refs.threeContainer.clientWidth;
      const height = this.$refs.threeContainer.clientHeight;
 
      this.scene = new THREE.Scene();
      this.camera = new THREE.PerspectiveCamera(75, width / height, 0.1, 1000);
      this.renderer = new THREE.WebGLRenderer();
      this.renderer.setSize(width, height);
      this.$refs.threeContainer.appendChild(this.renderer.domElement);
 
      this.camera.position.z = 5;
    },
 
    loadEnvironmentMap() {
      const loader = new RGBELoader()
      loader.load('./textures/envMap.hdr', (texture) => {
        this.scene.environment = texture;
      });
    },
 
    loadModel() {
      const loader = new GLTFLoader();
      loader.load('./models/map.gltf', (gltf) => {
        this.scene.add(gltf.scene);
      });
    },
 
    addControls() {
      this.controls = new OrbitControls(this.camera, this.renderer.domElement);
    },
 
    animate() {
      requestAnimationFrame(this.animate);
      this.controls.update();
      this.renderer.render(this.scene, this.camera);
    }
  }
};
</script>
 
<style>
div {
  width: 100%;
  height: 100vh;
}
</style>

这个例子中，我们创建了一个Vue组件，其中包含了Three.js的初始化、环境光照加载、3D地图模型加载以及轨道控制的基本实现。这个简化的代码展示了如何将Three.js集成到Vue项目中，并实现基本的3D地图可视化功能。
