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. In combination with other standard local mesh operators, e.g., connectivity optimization and local tangential smoothing, our algorithm is able to remesh efficiently a low-quality mesh surface. Our approach can be applied directly or used as a post-processing step following other remeshing approaches. Our method has a similar computational efficiency to the fastest approach available, i.e., real-time adaptive remeshing [1]. In comparison with state-of-the-art approaches, our method consistently generates better results based on evaluations using different metrics.
Experimental Results
Comparison of the remeshing results on models with sharp features or boundaries. The joint, sculpt models are presented from top to bottom. For each test model, the top row is the input mesh and the remeshing results of previous approaches, including RAR [1], MAI [8], FPO [48], IFM [10], and NOB [11]. The bottom row of each test contains the results of our method (left most) and the results by using the corresponding mesh as initialization. Note that the results of SPP [9] are not shown here as it does not support feature preservation.
