支持草绘的概念图形设计系统研究与实现

Research and Implementation of the Sketching Design System

提出了一个支持概念图形草绘设计的CAD系统原型。采用面向对象的方法设计出系统基本的类结构,实现了笔式输入方式与传统的WIMP交互方式的相互集成。研究了草绘设计的一些关键技术:草绘笔划分段处理与识别、草图规整、手势设计与识别和基于手势的草图编辑操作等,并通过实例对其实现过程进行了说明。

The paper presented a computer aided sketching design system for conceptual drawing which integrated a pen-based input way with the traditional WIMP-based interactive way. The class hierarchy of the system was proposed by using the object-oriented method. Some key technologies of sketching design were researched, such as stroke segmentation, primitive recognition, sketch beautification, gesture design and recognition, gesture-based sketch editing, etc. Finally, an instance was introduced to describe the editing process of sketch.
