使用QT4.5进行GUI编写。

Python作为脚本系统，实现场景描述。

notes: Now I'm trying to integrate a scene description system using python as the script language

to replace the hard-coding description, and it is half finished, So you cannot render images by the

current system.

You can try the backup version in the download section to render images. To build the system,

you need the QT4.5 already installed on your OS.
