This paper presents a new algorithm for solving the BFS of aspherical surfaces to suppress some deficiencies in the existing BFS algorithms. In the proposed approach  it is not only suitable for the conic surface  a BFS is constructed  but also for higher order aspheres. The obtained asphericity and material removal function is more suitable for the machining and test. (2012) Trans Tech Publications  which passes through both sides of endpoints in the section o -?xy of the aspherical surfaces  Switzerland.  the center of the BFS is shifted along the x-axis  and its radius of curvature is automatically computed. The variable step size method is proposed to speed up the convergence of the iteration. Through numerically solving the BFS of conic and cubic surface  the advantages of the proposed approach are verified. The results show that the proposed approach is of rapid convergence  and high accuracy   Some methods for the fabrication of large diameter off-axis paraboloids 会议论文  OAI收割 Dalian, China, 2010-4-26 作者:  Li Depei 收藏  |  浏览/下载：28/0  |  提交时间：2014/01/05 off-axis parabolic surface  the best fit sphere  the greatest volume of non-sphere  sagittal depth   Volumetric Algorithm of Short Sliding Distance Landslide 会议论文  OAI收割 Itcs: 2009 International Conference on Information Technology and Computer Science, Proceedings, Vol 2, Proceedings, Los Alamitos Li Song; An Yu-lun; Gao Si; Wang Ying 收藏  |  浏览/下载：14/0  |  提交时间：2014/12/07 landslide volume  sliding surface  ground surface of landslide mass  fit  double integral   Methods to Determine Best-Fit Sphere for Off-Axis Aspheric Surface 会议论文  OAI收割 Chengdu, China, 2007-7-8 作者:  ZHU Zheng;  ZHENG Li-xin 收藏  |  浏览/下载：33/0  |  提交时间：2013/12/29 Off-axis aspheric surface  Root mean square of asphericity  Best-fit sphere  Constraint conditions  Cyclic Coordinate Method   C-1 modeling with A-patches from rational trivariate functions 期刊论文  OAI收割 COMPUTER AIDED GEOMETRIC DESIGN, 2001, 卷号: 18, 期号: 3, 页码: 221-243 作者:  Xu, GL;  Huang, HC;  Bajaj, C   |  收藏  |  浏览/下载：23/0  |  提交时间：2018/07/30 algebraic surface  rational A-patch  surface fit  triangulation
