Question

我正在尝试使用three.js渲染一个.obj，我看了几个例子并想出了怎么做但我的html代码似乎不起作用！我只看到一个黑屏。我附上了下面的代码，我做错了什么？我是一个完全的菜鸟，所以任何帮助将不胜感激。谢谢！

            // scene

            scene = new THREE.Scene();

            var ambient = new THREE.AmbientLight( 0x101030 );

            directionalLight.position.set( 0, 0, 1 ).normalize();
            scene.add( directionalLight );


            // model

            var loader = new THREE.OBJLoader();
            loader.load( "/obj/smiley.obj", function ( object ) {

            camera.lookAt( scene.position );

            renderer.render( scene, camera );

Answer 1

您需要使用EventListener：

var loader = new THREE.OBJLoader();
loader.addEventListener( 'load', function ( event ) {

    scene.add( event.content );

});
loader.load( "/obj/smiley.obj' );

Answer 2

.obj文件是否附带.mtl文件？它们必须放在同一个文件夹中，否则OBJLoader将不会加载任何内容。

使用three.js渲染obj文件，什么都没有显示？
