摘　　要：递归分割曲面的尖锐特征不仅能够增加递归分割曲面的造型功能,而且有助于保留网格模型上的重要特征,其简捷、高效等特点具有广阔的应用前景。为解决在实际应用过程中存在的问题,进一步推动其在产品建模和机械制造中的应用,在特征造型方面,实现了递归分割曲面的折痕、尖刺、角等绝对尖锐特征造型,避免了为构造特殊效果而建立不同的递归分割算法,增加递归分割曲面的造型能力。The sharp features of recursive division surfaces can not only increase the recursive division surface modeling capabilities,but also help keep the grid model of the important features.Its simple,efficient and other features make it have broad application prospects.To address the actual problems in the application process and further promote its product modeling and mechanical manufacturing,in aspects of feature-based modeling,absolutely-sharp feature modeling such as crease,dart,and corner in the recursive-subdivision surface is achieved,to avoid establishment of different recursive-subdivision algorithm in case of constructing special effect,which increases the capacity of recursive division surface modeling.
