[vtkusers] vtkImplicitFunction

[Gwenaël Guillard]

Hello,

I derive the class vtkImplicitFunction and I write the EvaluateFunction(
) method of my new class newClass. Thanks to a vtkSampleFunction,  a
vtkContourFilter, a vtkPolyDataMapper and a vtkActor, I'm able to
visualize my surface. The problem is when I modify a parameter of
newClass, I want to recompute the surface and I don't know how to
update.

Thank you for your help,
