Design of Several Mesh Edit Tools
一类交互式网格曲面编辑工具的设计

It is of great challenge to interactively modify surface in modeling systems.An intuitionstic deformation method is presented, which is implemented through a set of mesh edit tools.Three edit tools: point edit tool, sphere edit tool and cube edit tool are provided. Different tool produces different deformation,and the deformation can be fine-tuned by adjusting some computational parameters.
