摘　　要：为满足草图设计过程中快速建模和简便交互的需要,提出了一种融合手势建模和轮廓建模优势的3维草图设计技术,主要包括基于单笔画的草图手势识别、2维草图识别规整、3维快速建模和模型编辑技术等。对忽略细节的3维建模采用自由手绘建模,而对于规则3维图形的建模则采用特征手势建模,以此支持快速建模。手势交互取代了传统的图形用户界面,更加符合设计师的草绘习惯。最后,开发了一个草图设计原型系统,并以杯子设计为例,验证了该技术和原型系统的有效性。To satisfy the requirement of quick modeling and convenient interaction in the process of product sketch design, a three--dimension sketch design technology was proposed, which combined advantages of gesture modeling and outline modeling. It mainly included sketch gesture identification based on single brush stroke, two--dimension sketch identification and modification, three--dimension rapid modeling, and model editing technology. Once the detail of sketch design was ignored, the freehand modeling was adopted. The feature--gesture modeling was used for regular three--dimension graphics. The gesture--based interface would replace the designer＇s habit of sketch design more than the traditional Graphical User Interface （GUI）. In addition, a sketch design prototype system was developed, and the effectiveness of this method and system were proved in the cup sketch design.
