一个利用OpenGL函数编辑的3D动态图像效果：各色圆球在倒立透明柜中不断无规则运动，有背景-A function of the use of OpenGL for 3D dynamic image editing effects: colored ball in an Inverted transparent counters constant random motion, there is a background

使用openGL生成一个透明的背景为灰色的立方体框架，并可以自动旋转-use the openGL produce a famework of a square,the back is brown and it can turn around automatically.

一个OpenGL模型的展示，用到了环境光和镜面反射改变效果，并且加入的环绕算法，背景用了半透明的效果-Demonstrate an OpenGL model uses ambient light and specular reflection effect change, and added surround algorithm background with a translucent effect
