VUE2——three.js模型渲染

<template>
  <div id="container"></div>
</template>
 
<script>
import * as THREE from 'three';
 
export default {
  name: 'ThreeModelRenderer',
  mounted() {
    const scene = new THREE.Scene();
    const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
    const renderer = new THREE.WebGLRenderer();
    renderer.setSize(window.innerWidth, window.innerHeight);
    document.getElementById('container').appendChild(renderer.domElement);
 
    const geometry = new THREE.BoxGeometry();
    const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
    const cube = new THREE.Mesh(geometry, material);
    scene.add(cube);
 
    camera.position.z = 5;
 
    const animate = function () {
      requestAnimationFrame(animate);
 
      cube.rotation.x += 0.01;
      cube.rotation.y += 0.01;
 
      renderer.render(scene, camera);
    };
 
    animate();
  }
}
</script>
 
<style>
#container {
  height: 100vh;
}
</style>

这段代码在Vue组件的mounted生命周期钩子中初始化了一个Three.js场景，包括一个立方体模型。然后，它设置了相机、渲染器，并将渲染器的DOM元素插入到页面中。最后，它通过循环调用requestAnimationFrame来使立方体旋转，从而实现了模型的渲染和动画展示。
