创建一个三维迷宫，支持替身通过一定交互手段在迷宫中漫游，基本功能包括：

读取给定的替身模型，加载到场景中。

键盘方向键控制替身转向与漫游。

有碰撞检测，替身不应当穿墙。

支持切换第一视角和第三视角进行观察。

迷宫场景中的墙、地面等应贴上纹理。

同时加入二维辅助地图，替身在三维迷宫探索的同时，在小地图中显示已经探索的区域；

在俯视状态下，可以通过鼠标点选替身需要到达的目的地，通过寻径算法，控制替身自动到达目的地；

迷宫地图交互编辑功能，例如，可以设计一个二维地图编辑器，根据用户的绘制，拉伸得到三维迷宫场景；

-Create a three-dimensional maze, to support avatars by means of interaction roam the maze, the basic features include: read a given stand-in model is loaded into the scene. Keyboard arrow keys to control avatars turn and roaming. Collision detection, a substitute should not be through the wall. Support switching the perspective of the first and third perspective to observe. Maze scene in walls, floors, etc. should be affixed texture. Two-dimensional auxiliary map, avatars in three-dimensional maze to explore at the same time, have explored the area in the small map　in the top state, you can click the mouse avatars need to reach the destination by routing algorithms that control the avatar automatically reach their destination　The maze map interactive editing features, for example, you can design a two-dimensional map editor, according to the user drawing, drawing three-dimensional maze scene
