Abstract

We introduce a novel algorithm for isotropic surface remeshing which progressively eliminates obtuse triangles and improves small angles. The main novelty of the proposed approach is a simple vertex insertion scheme that facilitates the removal of large angles, and a vertex removal operation that improves the distribution of small angles. Combined with other standard local mesh operators, e.g., connectivity optimization and local tangential smoothing, our algorithm is able to remesh a

low-quality mesh surface efficiently. Our approach can be used as a post-processing step following other remeshing approaches or applied directly. Our method has a similar computational efficiency compared to the fastest approach available, i.e., real-time adaptive remeshing [1]. Compared with state-of-the-art approaches, our method consistently generates better results evaluated by different metrics.
