实现了3D的基本功能，里面的流程控制值得借鉴。其实是参考了一本老的3D书做的，看过就知道-realized 3D basic functions, which control the flow is worth learning from. Is a reference to the old 3 D books, read on to know

3Djava游戏,含代码和流程图哦!非3D组件,直接使用点,面,线算法.很好的图形学教程.有代码和流程图,值得学习.-3Djava games, including code and flowcharts Oh! Non-3D components, direct use of point, surface, line algorithm. A very good graphics tutorials. There is code and flow charts, worth learning.
