In this paper a systematic remeshing method of triangle mesh surface is proposed for CAD applications. A density-sensitive edge marking function is proposed for surface resampling. Surface energy minimization is used to redistribute vertices for face geometry regularization. A simulated annealing method is proposed for vertex connectivity optimization. During each stage, the deviations from original mesh are prevented, and the boundaries and features are well preserved. While all modifications are performed locally, the error-prone global parameterization is entirely avoided. The advantage and robustness of this technique are verified by many examples from real-world product design.
