计算机支持的智能草图技术研究及实现

ISID:Pen Based Intelligent Sketching Tool

首先论述了作为CAD技术当前研究前沿的计算机支持的智能草图技术研究现状。构建出智能草图的技术体系,包括基于单笔划的自然手势界面,徒手草图输入,草图识别与基于草图的几何建模。最后给出基于著名几何造型核心ACIS开发的智能草图工具原型系统ISID,它具有一个支持笔输入的用户界面,并能和典型的CAD系统实现集成。初步应用证明该系统具有很强的实用性和可扩展性。

Sketching activity and computer supported sketching,one of the hot points of current CAD research,is intro-duced.The technique system of intelligent sketching is presented,including the pen based natural gesture interface,free-hand sketching input ,sketching recognition and sketch based solid modeling.With the famous modeling engine,ACIS,as the geometric kernel,a prototype sketching system,ISID,is built.This sketching tool has a pen-based interface,and can exchange model data directly with typical CAD systems.Experiments have certified its practical and promising future.
