摘要：
A precision-preserving mesh generation algorithm for computer aided design (CAD) solid models was proposed aiming at the issues of large errors, high resolution and non-watertightness in the surface mesh models generated by boundary representation models. The watertightness of the mesh was ensured by synchronously generating aligned pairs of vertices on shared curves. A continuous representation was utilized to design the target edge length of the mesh, resulting in a high-precision, low-resolution mesh. The algorithm can achieve higher-precision meshes with fewer mesh faces, while maintaining comparable mesh quality compared to existing open-source mesh generation software. © 2024 Zhejiang University.
