导出的文件?
Three.js 提供了一个可以解析各种 3D 格式的库 Three.js/editor 目录下有一个工具 three.js/editor/examples/js/libs/stl-loader.js,它可以读取 .stl 格式的文件
1. 3D MAX 编辑并导出文件
打开3D MAX软件,选择你要导出的模型。
点击File->Export,选择.STL格式,然后保存模型至电脑中。
2. 准备使用Three.js
从Three.js的 官方网站 下载 three.min.js或three.js,然后引入它:
```html
<script src="js/three.min.js"></script>
```
3. 加载并解析.STL 文件
three.js/editor 目录下有一个工具 three.js/editor/examples/js/libs/stl-loader.js,它可以读取 .stl 格式的文件。
```html
<script src="js/three.min.js"></script>
<script src="js/STLLoader.js"></script>
<script>
var loader = new THREE.STLLoader();
loader.load( 'model.stl', function ( geometry ) {
var material = new THREE.MeshPhongMaterial( { color: 0xff5533, specular: 0x111111, shininess: 200 } );
var mesh = new THREE.Mesh( geometry, material );
mesh.position.set( 0, - 0.25, 0.6 );
mesh.rotation.set( 0, - Math.PI / 2, 0 );
mesh.scale.set( 0.5, 0.5, 0.5 );
mesh.castShadow = true;
mesh.receiveShadow = true;
scene.add( mesh );
} );
</script>
```
4. 显示模型
最后,在你的场景中添加该模型:
```html
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title></title>
</head>
<body>
<script src="js/three.min.js"></script>
<script src="js/STLLoader.js"></script>
<script>
var renderer, camera, scene;
var loader = new THREE.STLLoader();
function init(){
renderer = new THREE.WebGLRenderer({ antialias: true });
renderer.setSize( window.innerWidth, window.innerHeight );
document.body.appendChild( renderer.domElement );
camera = new THREE.PerspectiveCamera( 75, window.innerWidth/window.innerHeight, 0.1, 1000 );
camera.position.z = 5;
scene = new THREE.Scene();
var light = new THREE.PointLight( 0xffffff, 2, 100 );
light.position.set( 50, 50, 50 );
scene.add( light );
loader.load( 'model.stl', function ( geometry ) {
var material = new THREE.MeshPhongMaterial( { color: 0xff5533, specular: 0x111111, shininess: 200 } );
var mesh = new THREE.Mesh( geometry, material );
mesh.position.set( 0, - 0.25, 0.6 );
mesh.rotation.set( 0, - Math.PI / 2, 0 );
mesh.scale.set( 0.5, 0.5, 0.5 );
mesh.castShadow = true;
mesh.receiveShadow = true;
scene.add( mesh );
} );
}
function animate(){
requestAnimationFrame( animate );
renderer.render( scene, camera );
}
init();
animate();
</script>
</body>
</html>
```
