论文摘要
具有高级别结构和特征保留财产利益工业应用的四边形网格最多。这样的四边形网眼仍然是一个挑战。使用表面叶面生成的四边形网眼具有最高的水平结构，但是它们缺乏保留功能。在本文中，我们使用高斯河网定理分析边界曲率，以确定是否存在边界矩形角度保存基于叶面的方法。当它存在时，我们采用了修改的双覆盖技术以及表面叶面方法来生成一个角色，可保留四边形网格。实验证明了我们算法的功效。
Quadrilateral meshes with high level structure and feature preserving property benefit industrial applications the most. Generation of such quad mesh remains a challenge. Quad meshes generated using surface foliation have the highest level structure, however they lack of the feature preserving ability. In this paper, we analyze the boundary curvature with Gauss-Bonnet theorem to determine whether a boundary rectangle corner preserving foliation based method exists. When it exists, we adopt a modified double cover technique together with surface foliation method to generate a corner feature preserving quad mesh. The experiments demonstrate the efficacy of our algorithm.
