Hi vtkusers

I would like to make a Mesh on any 2D surface with only Quadrilateral elements.

Moreover, i 'd like to be able to make some local refinement on the mesh, near from the boundaries of the surface.

I thought I should use a vtkUnstructuredGrid to represent my mesh and my attributes data. But I dont know how to initialize the mesh and how I can do the local

refinement. Could someone help me ?

Thanks a lot :)
