...-of-the-art surface mesh generation methods aim for both algorithmic robustness and output quality. The input may be a triangle soup geometry with potential defects, whereas the output should be watertight, manifold, and free of self-intersections (Shalom et al., 2010 ; Berger et al., 2017...

...). Originality/value This paper proposes a lightweight interactive approach for unstructured surface mesh generation, which can speed up mesh generation. There are two main steps to generate unstructured surface mesh for dirty CAD models (Zheng et al., 2016). It can be seen...
