面向对象三维动画仿真的实现

Implementation of Object-oriented 3D Dynamic Graphics Simulation

该文阐述了采用面向对象的方法进行动画仿真的过程和实现方法，介绍了图形数据结构、类的建立、体素的快速消隐处理、三维几何造型技术和基于物理的动画处理技术。最后，给出尾鳍推进装置三维动画仿真的实例。

This paper introduces a pratess and implementation method of computer graphic simulation by means of object-oriented pro- gramming. The contents are graphic data structure, class constructin, hidden-line quick elimination of volume element, 3D geometric mod- elling and physicsed animation technique. As an example, the 3D dynamic graphics simulation demonstration of the propulsion device by fin stroke is given in the end of the paper.
