摘要
本文介绍了计算机屏幕动画直接生成的原理及实现方法。计算机屏幕动画技术被广泛应用于计算机辅助教学课件中。但动画程序的编制比较复杂,利用本文介绍的方法,用户仅需以交互方式进行屏幕作图及图形编辑等示教操作,软件即可记录所进行的操作并自动生成动画程序。这样,操作人员完全不必考虑编制动画程序的细节问题,而直接从屏幕出发,构思动画过程,然后以简单的键盘操作,直观、方便、迅速、精确地生成相应的动画程序,从而大大提高了工作效率。 由于图形是动画设计的基础,因而本文对作者自行开发的绘图工具程序PT也作了简要介绍。该程序具有较强的绘图、图形编辑及图形管理功能,可以方便地设计各种高质量的图形及图案,为直接生成动画程序打下了良好的基础。
This article introduces the idea and implementation of automatic programming of computer screen cartoon used widely in CAI(Computer Aided Instruction) text-wares. It is rather difficult to program a computer cartoon. However, using the method introduced, user needs only to draw and edit pictures on screen in interactive mode and the cartoon program will be produced automatically, so that a cartoon picture can be designed without thinking the details of programming. A computer graphic tool PT(Picture Tool) developed by authors is also introduced. With more powerful functions of drawing, editing and managing screen pictures, PT can be used to design pictures and patterns with high quality so as to lay a good foundation for computer screen cartoon.
