[vtkusers] Display BSpline surface in vtk

[Yves Fricaud]

Hello

We would like to use vtk in our project because it's a powerfull tool to
display result of postreatment.
But at the begining of our process we have a BRep representation of the
model.  BRep  is based on surfaces like BSpline and theses surfaces are
restricted by a set of 2d curve on the surface.

We would like to know how to display this objects with VTK and also how
to find the selected object from a pick.

Thank you for your help
Best Regards

Yves
