[vtkusers] visualizing NURBS++ surfaces (maybe a FAQ??)

It looks like the class vtkExplicitCell is abstract and there seems to be no
child classes VTK. I haven't used it (subclassed), so cannot help there.
Maybe the NURBS++ library can also output triangles or quads (it manages to
generate them for OpenGL rendering, so they exist somewhere).
Then you could fill a vtkPolyData with these triangles/polygons and render
as usual with VTK.

Subject: [vtkusers] visualizing NURBS++ surfaces (maybe a FAQ??)
I'm using an open source library for NURBS management, called NURBS++.
I'm able to do everything: creation of the surface, control points moving,
surface points moving, visualiation of the surface with OpenGL
I'm developing a VTK based application, and now I need to visualize the
NURBS++ surfaces into VTK pipeline, therefore without using gluNurbsSurface
but the VTK rendering
I found in the VTK documentation the class vtkExplicitCell.h that tells
about NURBS surfaces, but I didn't understand how to use it. (
Do you have some suggestion please?
