Question

我正在尝试修改three.js示例的代码以加载在.js中转换的.obj。这使用BinaryLoader.js加载对象。该对象未在我修改的代码中显示。到目前为止我的代码如下

有人知道这个问题吗？

Answer 1

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，所以你必须将它缩放200才能从你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);
});

在three.js中使用二进制加载器加载对象不起作用
