[vtkusers] How to modify (points, cells) a visualized polydata object

[bailleul jonathan]

Dear All,

I know this question has been around under many forms in this forum, and 
that the label 'newbie' is generally associated with it ;(
But even though I recently got the books and looked for the ML archives, 
I didn't manage to solve it.


So: I have 2 important applications in mind for which I would need to:
- modify the points positions only (fixed connectivity)
- modify the points and the cells (everything, then)

For what I've read, I fear the only solution would be to remove the 
actor representing the polydata, and then to build a new actor from 
scratch.

This could suit the latter application (polydata represents the cutting 
of an ImagePlaneWidget and a polydata object), but would definitely kill 
the first one (modify point positions only while moving cursors 
representing shape coefficients for the well-known Point Distribution 
Model)


I accept any criticism and any hint!


By advance, thank you for your time,
