We present a method for repairing topological errors on solid models in the form of small surface handles, which often arise from surface reconstruction algorithms. We utilize a skeleton representation that offers a new mechanism for identifying and measuring handles. Our method presents two unique advantages over previous approaches. First, handle removal is guaranteed not to introduce invalid geometry or additional handles. Second, by using an adaptive grid structure, our method is capable of processing huge models efficiently at high resolutions.
我们提出了一种修复实体模型上拓扑错误的方法，这些错误以小表面手柄的形式出现，通常源于表面重建算法。我们利用一种骨架表示法，它提供了一种识别和测量手柄的新机制。与以前的方法相比，我们的方法具有两个独特的优势。第一，保证去除手柄不会引入无效几何形状或额外的手柄。第二，通过使用自适应网格结构，我们的方法能够在高分辨率下高效地处理大型模型。
