三维实体造型动画系统的设计及实现

Design and implementation on model animation, system of three-dimensional solid

造型动画是基于物理模型的计算机动画,遵循真实的运动学和动力学规律,而三维实体造型动画一直是动画开发人员及用户追求的终极目标。论述了三维实体造型动画系统的动画表现原理和动画运动轨迹的确定。应用Visual C++结合OpenGL实现了旋转、爆炸和解除爆炸的三维实体造型动画,并利用Visual C++的AVICap窗口类实现了动画过程的视频捕获,以及将捕获结果以AVI文件的形式记录下来。

Model animation, a kind of computer animations, bases on physical models and follows the rules of kinematics and kinetics and model animation of three-dimensional solid is the ultimate goal of animation developers and users. How to display animation and determine animation motion trajectory is discussed. Implement rotating animation, exploded animation and retracting exploded animation are realized using visual C++ and openGL. And the video capturing of animation process is realized using AVI cap of visual C++ and the video capture result is recorded as an AVI file.
