摘要：基于三维实体造型设计的动画,其形成文件通常比较大,运行环境要求较高,在工程制图的远程教育网络中,大大影响传输速度,从而降低了教学效率。依据不同视角得到不同轴测投影的原理,用VisualLisp编程,以视角为变量,连续变化,每个视角下得到的轴测投影图经过消隐后,生成轴测投影动画,所形成的文件大大减小。且可直接在AutoCAD中运行。为计算机三维动画在网络中的传输提供了一个实用的方法。
The animation generated by means of 3D solid modeling is always formed as a large document. It demands high conditions to display perfectly. The document is so large that it lowered the transmission speed and teaching efficiency through the distant educational network of engineering drawing. According to the pinciple of different axonometric projection at different angles, Visual Lisp can be used to make programs. While angle as parameter varies continuously, the axonometric projection at every angle is processed by line hidden. The document of animation generated by this means is much minimized, and it can directly run in AutoCAD. It facilitates the 3D animations in transmitting through the network.
