Abstract

Abstract:

In order to meet the practical engineering application needs of complex hole restoration,this paper proposed a robust mesh model restoration architecture with C0~C2 continuity based on zipper closure principle and thek order discrete Euler-Lagrange equation derived from minimizer of the surface energy functional.The final experimental results show that the proposed hole restoration method can deal with complex holes efficiently and correctly.

Key words: triangular mesh;hole restoration;complex hole boundary , triangulation, hole , repairing

摘要：

为了满足实际工程应用对复杂形态孔洞修复的需要,模拟拉链闭合原理,并基于局部最优化的权值规则和曲面最小能量值特性的k阶离散欧拉-拉格朗日方程,提出了一种具有C0~C2连续的网格模型修复架构。实验结果表明,该孔洞修复架构能有效地对复杂孔洞边界进行C0~C2连续修复。
