对输入的数据点进行三角刨分，并将三角刨分后得到的结果进行四边形划分，得到四边形网格-Input data points on the plane triangular points, and sub-triangular plane quadrilateral obtained by the results obtained quadrilateral mesh

2D凸多边形的三角网格生成，可用gridgen。-2D triangular convex polygon mesh generation, available gridgen.

实现三角网格的分割算法，对有噪声的模型也能够很好的分割效果。-Realization of triangular mesh segmentation algorithm, with noise model can also be a good segmentation effect.
