A Shell Algorithm for Solid on Boundary Representation
基于边界表示的体抽壳算法

The shell operation of solid is an effective method to construct a solid with shape of thin shell. In this paper, the authors describe the mathematical definition of shell operation on regular solid with boundary representation, and present an algorithm for shell operation. The algorithm implements the solid's 3D operation by 2D merging operation of loops in surface's parametric region. So the complexity of problem is reduced.
