I have a 2D Dataset (surface) that I am planning to define using a 2D BSpline (GeomAPI_PointsToBSplineSurface).
Is there a way to estimate and control how much deviation from original data would be, if the points are converted to and back from a BSpline.
The problem is that I have a really small allowable tolerance in defining a surface and wanted to evaluate whether to approximate the surface using a BSpline

Hi Suneet,
in the GeomAPI_PointsToBSplineSurface constructor you have a parameter
const Standard_Real Tol3D
that lets you control the deviations. The problem is this toleration is checked only at the given (for approximation) points. Maybe you could try
GeomConvert_ApproxSurface
I haven't tried that but it look promising.
