好的,下面是一个简单的示例代码,演示如何使用Three.js加载Obj和Mtl文件,并上贴图(注:需要先引入Three.js库):
```html
<!DOCTYPE html>
<html lang="en">
<head>
<title>Load Obj and Mtl file with texture using Three.js</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
body {
margin: 0;
overflow: hidden;
}
canvas {
width: 100%;
height: 100%;
}
</style>
</head>
<body>
<script src="https://cdn.jsdelivr.net/npm/three@0.131.2/build/three.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/three@0.131.2/examples/js/loaders/MTLLoader.js"></script>
<script src="https://cdn.jsdelivr.net/npm/three@0.131.2/examples/js/loaders/OBJLoader.js"></script>
<script>
// 创建场景、相机、光源等
var scene = new THREE.Scene();
var camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.set(0, 0, 5);
var light = new THREE.PointLight(0xffffff, 1, 100);
light.position.set(0, 1, 5);
scene.add(light);
// 加载模型
var mtlLoader = new THREE.MTLLoader();
mtlLoader.load('path/to/your/file.mtl', function(materials) {
materials.preload();
var objLoader = new THREE.OBJLoader();
objLoader.setMaterials(materials);
objLoader.load('path/to/your/file.obj', function(object) {
// 加载完成后,设置材质、纹理等
object.traverse(function(child) {
if (child instanceof THREE.Mesh) {
child.material.map = new THREE.TextureLoader().load('path/to/your/texture.jpg');
child.material.needsUpdate = true;
}
});
// 加入到场景中
scene.add(object);
});
});
// 创建渲染器
var renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);
// 渲染场景
function animate() {
requestAnimationFrame(animate);
renderer.render(scene, camera);
}
animate();
</script>
</body>
</html>
```
您需要将代码中的 `path/to/your/file.mtl` 、`path/to/your/file.obj` 和 `path/to/your/texture.jpg` 替换为您自己的文件路径。
