摘要

通过在均匀网格的对偶上生成三角形网格或四边形网格,对体数据进行曲面重构有几种方法。这些方法通常提供比著名的行进立方体质量更好的网格。然而,它们有一个共同的问题:网格不能保证是多元的。我们通过提出一个后处理例程来解决这个问题,该例程通过局部细化来解决所有非流形边。新顶点被定位在三线插值上。我们在广泛的数据集上验证了我们的方法,并表明我们能够解决所有非流形问题

Resolving Non-Manifoldness on Meshes from Dual Marching Cubes
There are several methods that reconstruct surfaces from volume data by generating triangle or quad meshes on the dual of the uniform grid. Those methods often provide meshes with better quality than the famous marching cubes. However, they have a common issue: the meshes are not guaranteed to be manifold. We address this issue by presenting a post-processing routine that resolves all non-manifold edges with local refinement. New vertices are positioned on the trilinear interpolant. We verify our method on a wide range of data sets and show that we are capable of resolving all non-manifold issues
