三角网格模型的快速剖切方法

A Fast Cutting Method for Triangular Meshes

提出了一种仅根据三角网格模型的三角面片集合对其进行平面剖切的方法。该方法根据在任意平面内指定的剖切线,将任意拓扑结构的三角网格模型剖切为子三角网格。该方法能实现三角网格模型的快速、高效剖切,在大型水电工程施工模拟中的应用进一步证实了该方法的有效性。

Triangular meshes are widely used mesh models.In this paper,a new cutting method for arbitrary triangular mesh by plane is presented based on the triangles set of the mesh only.Given cut-curve in any plane,triangular mesh with different topologies can be cut into child triangular meshes by the method.The method can cut triangular meshes rapidly and effectively,and applications of the method in simulating large water and hydropower project constructing proves its effectiveness.
