以下内容引用自README.md ，大家请首先参照这个配置

## convert-to-threejs ##

Utility for converting model files to the Three.js JSON format

## Supported Formats ##

*  Fbx (.fbx)
 *  Collada (.dae)
 *  Wavefront/Alias (.obj)
 *  3D Studio Max (.3ds)

## Usage ##

convert_to_threejs.py [source_file] [output_file] [options]
    
    Options:
      -t, --triangulate force non-triangle geometry into triangles   -x, --ignore-textures don't include texture references in output file   -u, --force-prefix prefix all object names in output file to ensure uniqueness   -f, --flatten-scene merge all geometries and apply node transforms   -c, --add-camera include default camera in output scene   -l, --add-light include default light in output scene   -p, --pretty-print prefix all object names in output file

## Current Limitations ##

*  No animation support
 *  Only Lambert and Phong materials are supported
 *  Some camera properties are not converted correctly
 *  Some light properties are not converted correctly
 *  Some material properties are not converted correctly
 *  Textures must be put in asset’s folder, and use relative path in the material

## Dependencies ##

### FBX SDK ###

*  Requires Autodesk FBX SDK Python 2013.3 bindings.

You can download the python bindings from the Autodesk website: 
      http://usa.autodesk.com/fbx/

Don't forget the visit the FBX SDK documentation website:
      http://docs.autodesk.com/FBX/2013/ENU/FBX-SDK-Documentation/cpp_ref/index.html

*Note:* If you use the OSX installer, it will install the Python packages into the following folder.

/Applications/Autodesk/FBX Python SDK/[VERSION]/lib/

If the tool still can’t find the FBX SDK, you may need to copy the `fbx.so`, `FbxCommon.py` and `sip.so` files into your site\_packages folder.

If you don’t know your site\_packages folder, run `python` from shell and paste this:

import site; site.getsitepackages()

### Python ###

*  Requires Python 2.6, 2.7 or 3.1 (The FBX SDK requires one of these versions)

sudo apt-get install build-essential
    wget http://www.python.org/ftp/python/2.6.8/Python-2.6.8.tar.bz2
    tar jxf ./Python-2.6.8.tar.bz2
    cd ./Python-2.6.8
    ./configure --prefix=/opt/python2.6.8 && make && make install

# 实际使用时我碰到的问题 #

![找不到FBX SDK][FBX SDK]  
找不到FBX SDK

这个错误郁闷了我好久，下载了数个版本的python和fbx sdk 依然没有得到解决  
![很多版本的fbx sdk][fbx sdk]

就在刚刚，我突然发现自己翻了个很坑的错误，**我下载的python到底是什么版本的？**

我也不清楚呀，我记得就是官网上随便下载了个windows 平台的安装包而已……  
于是问题就明确了，我一直以为我用的是64位版本的python，但实际上我下载的几个都是32位版本的。

# 描述下配置方法吧 #

1.  安装python ，根据readme的建议，我们可以选择2.6，2.7，3.1。
2.  选择FBX SDK 要与自己的python 版本相一致（我这里使用的是2.7版本的python 和2015.1的FBX SDK）
3.  打开FBX SDK的安装目录，…\\Autodesk\\FBX\\FBX Python SDK\\2015.1\\lib 将自己对应版的的文件夹内的内容复制出来，我这里需要复制的是Python27\_x86 文件夹内的内容  
    ![复制相应文件夹内的内容][20160913150113911]
4.  打开你的python 目录，找到site-packages文件夹 例 …\\Python27\\Lib\\site-packages , 然后将刚才的三个文件复制在这里![复制文件][20160913150413244]
5.  测试下fbx sdk 配置是否已经成功  
    可以运行 Autodesk\\FBX\\FBX Python SDK\\2015.1\\samples 目录下的一些例子py文件进行测试，如果不报错，则表示FBX SDK配置成功

## 小贴士 ##

打开cmd 一点点输入路径太慢了，可以先输入python 然后用鼠标点住将文件拖拽到cmd窗口上，文件的路径就会直接打在上面，挺方便的。
