WIMP-Based electronic teaching systems can not meet teachers' requirements of natural and efficient interaction, especially continuous drawing and writing in geometry teaching. In this paper, an intelligent pen-based whiteboard system for dynamic geometry visualization is designed and implemented.

计算机辅助教学系统目前已在教学中大量应用，然而，基于WIMP界面范式的电子课件系统，无法满足教师在课堂教学互动中需要与用户界面自然、高效、连续性交互的需求，尤其是几何教学中连续书写板书、自由勾画图形、动态几何定理演示等。

But it turns out there is a very good reason why we are crocheting it because many organisms in coral reefs have a very particular kind of structure. The frilly crinolated forms that you see in corals, and kelps, and sponges, and nudibranchs, is a form of geometry known as hyperbolic geometry.

但我们有一个很好的理由来用钩针编织：因为很多在珊瑚礁中的生物有机体，如裸鳃类动物、珊瑚礁、海藻及海绵中，有非常特别的一种结构，就是你所看到的裙衬褶边形式。
