摘要
介绍了在AutoCAD环境下的动画制作方法。以内嵌的AutoLISP编程语言为基础,提出了使用作图法获得给定参量所对应的函数值和生成动画帧的方法,并通过AutoLISP的系统变量TDUSRTIMER实现动画播放速度的精确控制。最后,以曲柄摇杆机构为例详实地阐述了动画程序的设计过程。
It presents the method of visual simulation in AutoCAD. Based on AutoLISP it designs plotting with parameters and generates a series of frames, the variable TDUSRTIMER in AutoLISP controls accurately the speed of moving pictures. The example shows the development process.
