B样条曲面(B-Spline Surface)是一种数学上用于描述三维形状的工具,它是B样条曲线在二维空间上的扩展。B样条曲面在计算机图形学、计算机辅助设计(CAD)、动画和许多其他领域都有广泛的应用。 B样条曲面由一组控制点和一个节点矢量定义。控制点构成了一个...

在上一篇文章中,我们提到了曲线插值,这一次我们趁热打铁,继续讨论插值问题,不过这一次是曲面插值。 八 曲面全局插值(Surface Global Interpolation ) 假设我们有m+1行n+1列的数据点Dij(0≤i≤m和0≤j≤n),并希望找到一个包含所有(p,q)次的b spline曲面。与曲线的情况类似,我们有数据点和度阶p和q作为输入。
When extracting b-spline surfaces, a mesh lets you visualize the surface. You can add curves from the mesh into the U and V directions for the extracted surface, forcing the surface to fit more closely to the mesh. You can display a deviation analysis to show the deviation between the ...
The present work reconstructs the disjoint surface with the help of a single equation from sectional data. At the same time it addresses the requirements of continuity, geometric and topological complexities. Behaviour of surface contours by varying control points is studied and then by electing an...
