Surface type

How can i build a COONs Surface or a NURBS surface with a table of point... not with curves...
right now i can build a BEZIER and aBSPLINE with the GEOM_SURFACE package and i need to make some transformation to the BSpline surface for example;i need to move with the mouse one of it's control point and see the modification apported to the surface...Can I do this with OCC5?
Thanks for your help

Hi jooo,

See interpolation techniques on how to do this (GeomAPI_PointsToBSplineSurface). Surface from constraints are also possible in OCC. Read some more in
