Vue使用Three.js 渲染glb、gltf模型

要在Vue中使用Three.js渲染glb或gltf模型，你需要安装three和@types/three，并创建一个Three.js场景，导入模型，并将其添加到DOM中。以下是一个简单的例子：

1. 安装Three.js：

npm install three

2. 安装Three.js类型定义：

npm install @types/three

3. 创建Vue组件：

<template>
  <div ref="threeContainer"></div>
</template>
 
<script lang="ts">
import { defineComponent, onMounted, ref } from 'vue';
import * as THREE from 'three';
import { GLTFLoader } from 'three/examples/jsm/loaders/GLTFLoader';
 
export default defineComponent({
  setup() {
    const threeContainer = ref<HTMLElement | null>(null);
 
    let camera: THREE.PerspectiveCamera;
    let scene: THREE.Scene;
    let renderer: THREE.WebGLRenderer;
    let loader: GLTFLoader;
 
    onMounted(() => {
      if (threeContainer.value) {
        const width = threeContainer.value.clientWidth;
        const height = threeContainer.value.clientHeight;
 
        camera = new THREE.PerspectiveCamera(75, width / height, 0.1, 1000);
        camera.position.z = 5;
 
        scene = new THREE.Scene();
 
        renderer = new THREE.WebGLRenderer();
        renderer.setSize(width, height);
        threeContainer.value.appendChild(renderer.domElement);
 
        loader = new GLTFLoader();
        loader.load(
          'path/to/your/model.glb', // 模型路径
          (gltf) => {
            scene.add(gltf.scene);
          },
          (xhr) => {
            console.log((xhr.loaded / xhr.total) * 100 + '% loaded');
          },
          (error) => {
            console.error(error);
          }
        );
 
        animate();
      }
    });
 
    function animate() {
      requestAnimationFrame(animate);
      renderer.render(scene, camera);
    }
 
    return { threeContainer };
  }
});
</script>
 
<style>
/* 确保容器充满整个父元素 */
#threeContainer {
  width: 100%;
  height: 100%;
}
</style>

确保替换path/to/your/model.glb为你的模型实际路径。这个例子使用了Three.js的GLTFLoader来加载glb或gltf模型，并在Vue组件挂载后开始渲染动画。
