提出了一种直观、高效地用于概念设计作图的徒手输入、进行几何变形的方法.采用此方法可以徒手输入两笔曲线(参考曲线和目标曲线)，并据此二曲线来移动多边形模型的顶点，从而达到变形三维模型的目的.解决了大曲率变形时产生的自相交问题.另外，还可用来定义变形影响区域.

The primary objective of this research is to develop an efficient and intuitive deformation tool for conceptual freeform geometric modeling by sketching input. With our method, users can sketch two strokes called the reference stroke and the target stroke to modify the model. The system moves vertices of the polygonal model so that the spatial relation between the original positions and the reference stroke is identical to the relation between the resulting position and the target stroke. The movement is perpendicular to the view direction, and vertices do not move in the view direction. Our method is related to the axial deformation The self-intersection problem is solved, and users can define an influence region by our deformation tool.
