摘要
本文讨论CAD中曲线与曲面拟合问题:单位算子逼近,磨光核函数构造,多结点样条插值,盈亏修正技巧,最后谈及非规整几何对象的计算机表达问题。
In this paper some problems on the curve-fitting and surface-fitting of CAD are discussed. These include the approximation to unit operator, constructions of smoothing kernel functions, many-knot spline interpolation schemes, the profit-loss revamping skill, and the computer representations for irregular geometric objects.
