提出了一种高效基于物理性质的算法来动态的塑造n边形曲面的外形.这种算法是基于曲面的物理性质.通过极小化一个能量泛函,用户能够直接使用不同形式的外力作为虚拟的塑造工具来改变n边形曲面的外形.用户也能够定义必要的几何约束来进一步控制曲面外形.与通常移动控制点的方法比较,这种基于物理性质的方法更直观和有效.

An efficient physically based surface sculpting method is presented in this paper for the interactivedeformation of n-sided surfaces. By minimizing an energy functional, the user is able to deform a surface byapplying different forms of forces directly, acting as virtual sculpting tools. The user is also able to define necessarygeometric constraints, so as to further control the surface shape. Compared with the traditional method that asurface is deformed by moving the control points, this method is much more intuitive and still is very efficient.
