  1. Several surface fitting methods are d iscussed. the parametrization of scattered data, the selection of knot vector, th e control of precision and the stability of the methods are analyzed, and the algorithm for b - spline surface fitting to scattered data in specified tolerance i s given

    2 ）研究了對散亂數據進行b樣條曲面擬合的問題，討論了數種常用的曲面擬合方法，分析了散亂數據的參數化、節點矢量的選取、精度控制、數值穩定性等問題。
  2. The aims of this thesis are researching some typical nurbs surfaces " geometric continuous conditions and pointing out the effects of knot vector and the degree of surface on geometric continuities

    本文的目的是研究一些典型的nurbs曲面的幾何連續條件，指出節點向量和曲面片的次數對幾何連續性的影響。
  3. 3 ) b - spline surface fitting to contour data is studied. a fitting method of using uniform knot vector is given. using this method, the resulted b - spline s urface not only satisfy the requirements of precision, but also possess fewer c ontrol vertices and good fairness, the computation speed is greatly improved t oo

    3 ）研究了逐層掃描數據的曲面擬合問題，給出了一種是利用統一的節點矢量進行擬合的演算法，用該法得到的b樣條曲面不僅可以滿足精度要求，而且具有較少的控制頂點和較好的光順性，計算速度也有較大的提高。
