我正在尝试修改 Three.js 示例的代码以加载在 .js 中转换的 .obj。它使用 BinaryLoader.js 来加载对象。该对象没有显示在我修改的代码中。到目前为止我的代码如下

if ( ! Detector.webgl ) Detector.addGetWebGLMessage();
var CARS = {

//body_materials: [ 2 ],

}
};
var container, stats;
var camera, scene, renderer;
init();
animate();
function init() {
container = document.createElement( 'div' );
document.body.appendChild( container );
var loader = new THREE.BinaryLoader( true );
document.body.appendChild( loader.statusDomElement );
// CAMERAS
camera = new THREE.PerspectiveCamera( 70, window.innerWidth / window.innerHeight, 1, 100000 );
// SCENE
scene = new THREE.Scene();
// LIGHTS
var ambient = new THREE.AmbientLight( 0x050505 );
scene.add( ambient );
renderer = new THREE.WebGLRenderer();
renderer.setPixelRatio( window.devicePixelRatio );
renderer.setSize( window.innerWidth, window.innerHeight );
renderer.setFaceCulling( THREE.CullFaceNone );
renderer.autoClear = false;
container.appendChild( renderer.domElement );
loader.load( CARS[ "Porsche" ].url, function( geometry ) { createScene( geometry, "Porsche" ) } );
}
function animate() {
requestAnimationFrame( animate );
render();
}
function render() {
var timer = -0.0002 * Date.now();
camera.position.x = 1000 * Math.cos( timer );
camera.position.y += ( - mouseY - camera.position.y ) * .05;
camera.position.z = 1000 * Math.sin( timer );
camera.lookAt( scene.position );
renderer.render( scene, camera );
}
</script>

有人知道这个问题吗？
最佳答案
你有一个 JSON 模型，所以你需要一个 JSONLoader 而不是 BinaryLoader，另一个问题是你的模型很小，所以你必须将其缩放 200 才能从初始化的相机中查看(fov=70) 。我将使用以下代码:
var loader = new THREE.JSONLoader(true);
loader.load(CARS[ "Porsche" ].url, function (geometry)
{
/*createScene( geometry, "Porsche" )*/
var material = new THREE.MeshBasicMaterial({color: 0xff0000});
var mesh = new THREE.Mesh(geometry, material);
mesh.scale.set(200,200,200);
scene.add(mesh);
});
更新:此处有完整代码

关于javascript - 在 Three.js 中使用二进制加载器加载对象不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29120273/
