先浏览了http://blog.csdn.net/rywaqpf/article/details/44836965，然后又奔到了https://stackoverflow.com/questions/10752055/cross-origin-requests-are-only-supported-for-http-error-when-loading-a-local/23758738#23758738，受其中的高票答案启发：
解决这个问题的方式有好几种。除了CMD的allow-file-access-from-files（自己还未试过），还可以在自己的PC上装一个服务器（刚好，前期装了LAMP），然后把文件（相关的html、js、css等等）拷贝过去，然后以类似http://localhost/XXX.html的形式访问，就可以了。

My crystal ball says that you are loading the model using either file:// or C:/, which stays true to the error message as they are not http://
So you can either install a webserver in your local PC or upload the model somewhere else and use jsonp and change the url to http://example.com/path/to/model
