[Paraview] How to see 3D Surface

[Ryan O'Kuinghttons]

Hi, 

I am trying to generate a 3D dataset from a 2D dataset with field 
values.  I read the thread in the subject line, and tried the suggestion 
but couldn't get it to work.  The suggestion was to use the calculator 
to do the following:

coords + vitesse_X*kHat


I tried doing things like:

coords + (my_field_value)*coordsZ

that didn't work, and I can't figure out what "vitesse" is, can you 
enlighten me?  Thanks!

Ryan
