[vtkusers] Moving points in an existing polydata object?

[Wesley Brooks]

Dear Users,

Do I have to resort to using (and learning how to use!) a
vtkProgrammableFilter to move points without affecting their
connectivity? I'm looking for a way to do this while the object is
rendered, so changes once made will be visable in the render window.

At present I think I'm doing it in a very inefficient manner by
getting a list of points and cells from the polydata and creating a
new polydata.

I'm using python 2.3 with VTK 4.2.2.

Thanks again in advance.

Yours Faithfully,

Wesley Brooks
