There are two methods are often used. A method is constructing some separate polyhedrons from vertex and edges of 3D wire-frame and combine the polyhedrons with each other one by one. Another is extracting wire-frame to some candidate faces and joining them up according to the nature of 3D object.In this paper, an algorithm of reconstructing 3D object from wire-frame was put forward.

目前有两种方法：一种是把三维实体看成由多个多面体组成的，相应的方法是将线框模型拆分成多个多面体，然后进行多面体的拼接组合重构三维实体；另一种方法是把三维实体看作由多个面组成的，相应方法是搜索可行面并根据三维实体的特点来重构。

Then, the method is extended to the problems of decomposing a polyhedron with or without holes into the minimum number of terrain polyhedra, both of which are also shown to be NP-hard.
