THREE.ObjectLoader的Three.js错误 [英] Three.js Error with THREE.ObjectLoader

问题描述

我似乎对Three.ObjectLoader有问题.我正在以JSON格式4.3导出场景.该场景包括几何形状，材质和灯光.场景将在Three.js编辑器中打开，并且没有任何错误.

I seem to be having issues with Three.ObjectLoader. I am exporting a scene in JSON Format 4.3. This scene includes geometries, materials, and lights. The scene opens in the Three.js Editor just fine without any errors.

我正在使用Three.js r70 master开发Firefox. 这是生成的json的链接: https://gist.github.com/fraguada/d86637f7987096b361ea

I am working on firefox with Three.js r70 master. Here is a link to the generated json: https://gist.github.com/fraguada/d86637f7987096b361ea

在查看器中，我试图编写代码，并且正在使用以下代码进行加载:

In the viewer I am trying to write I am using the following code for the loading:

var manager = new THREE.LoadingManager();
manager.onProgress = function ( item, loaded, total ) {

    console.log( item, loaded, total );

};

// instantiate a loader 

var loader = new THREE.ObjectLoader(manager);

loader.load( 
    // resource URL coming from other file
    Name, 
    // Function when resource is loaded 
    function ( result ) 
    { scene.add( result.scene ); }, 
    // Function called when download progresses 
    function ( xhr ) 
    { console.log( (xhr.loaded / xhr.total * 100) + '% loaded' ); }, 
    // Function called when download errors 
    function ( xhr ) 
    { console.log( 'An error happened' ); } 
);

在控制台中，我看到以下内容:

In the console I see the following:

THREE.WebGLRenderer 70  three.min.js (line 513)
100% loaded content.js (line 117)
THREE.Object3D.add: undefined is not an instance of THREE.Object3D. three.min.js (line 164)
js/Test83.js 1 1    content.js (line 86)

错误也出现在7674行的未缩小的three.js中

The error also appears in the unminified three.js in line 7674

如果我在Three.js编辑器中创建几何图形和其他对象并将其导出为场景，也会出现此问题.

This issue also appears if I create geometry and other objects in the Three.js editor and export it as a scene.

问题似乎在这里:scene.add( result.scene ); 假设THREE.ObjectLoader可以使用文件中的JSON是不正确的吗?在我发布的代码中，如果删除scene.add( result.scene );，似乎文件至少加载了(数据加载，没有可视化的几何图形)，因为没有错误出现.如果我的场景具有多个网格，则进度将输出到控制台(已加载10％，已加载20％等).

The issue seems to be here: scene.add( result.scene ); Am incorrect in assuming the THREE.ObjectLoader can consume JSON from a file? In the code I post, if I remove scene.add( result.scene ); it seems the file loads at least (data loads, no geometry is visualized), as no errors appear. If I have scenes with many meshes, the progress gets output to the console (10% loaded, 20%loaded, etc).

任何见解将不胜感激.

推荐答案

我认为您应该改为scene.add( result ).
