# Different results with BSplineSurface and BSplineFunction [closed]

There seems to be some differences when plotting a surface with BSplineSurface and with BSplineFunction.

Points={...}

A=BSplineSurface[Points]
B=BSplineFunction[Points]

PlotA=Graphics3D[A]
PlotB=ParametricPlot3D[B[u,v],{u,0,1},{v,0,1}]


Notice the ripples when using BSplineFunction (Second image below). Results from 'BSplineSurface' seems much more "natural".

Any ideas on how to make results from BSplineFunction look like the ones from BSplineSurface?

• They're supposed to give equivalent results. Try to increase the PlotPoints setting of ParametricPlot3D[]. – J. M.'s discontentment Oct 8 '15 at 12:09
• @J. M. You are right. Thanks! – Art Oct 8 '15 at 15:05

As @J.M.isback says, increasing the number of PlotPoints in ParametricPlot3D solves the problem.
