“…3D mesh feature‐preserving algorithms can be roughly divided into traditional methods [YOB02, WYP*14, ZFAT10, FDCO03, ZLWZ17, LWLL18, ZLW*19, SRML07, LDC15, WFL*15, LGXQ21, LLW*21] and data‐driven methods [WLT16, ZLZ*19, AFB20, LZF*20, WHW*19, WGH*19, LLZ*20, ZSW*22, SFD*22, ZLJ*22]. Traditional methods are mainly based on filtering algorithms or optimization algorithms.…”
