基于OpenGL几何变换函数的动画实例

The Animation Based on Geometric Transformation Functions of OpenGL

该文介绍了使用OpenGL进行基本几何变换和复合变换的方法,并通过定时器函数实现了模拟天体的公转、自转及脉冲缩放的动画。

This article introduces the geometric transformation and composite transformation with the functions of OpenGL. It also designs an animation which emulates celestial body＇ s revolution, rotation and scale in pulse cycle with the help of the timer function.
