[Paraview] translate geometry in space

[Tanaka Simon]

Dear ParaView Users,

I have a vtm 2D data structure, containing:
-> vtp polygons
-> vti image data (field) data


now i want to translate the polygons (for an 'explosion view'), i.e. i 
want to add +1 to all z-coordinates of the polygons.


how can i do that? do i have to code it in the "programmable filter"?


thanks for any suggestion
simon
