Simon,
Assuming your 2D datum set is in x,y-coordinates, one can expand this to
3D by adding a 0.0 value for the "missing" z-coordinate.
PV has a Transform filter that will then let you add a constant value to
the z-coordinate, or, equally easily, scale the z-coordinate.
On the other hand, if you really want to create a "carpet" plot that
makes your 2D datum set appear as 'mountains and valleys,' one can
likewise add the datum attribute (for example, density) as if it were
the z-coordinate. Again, PV's Transform filter will let you scale the
z-coordinate into a range that makes the image pleasing. It will be a 3D
image, that is easily oriented for viewing. The coloring can be either
by any of the point values, or a single color of your choosing.
There may be a more direct way to achieve this that someone else can
explain?
Hope this helps.
Sam

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
