[GRASS-user] from abstract contour to 3D

[János]

Hi,

Using Mathematica I can create from an abstract data set a contour  
graphics.  It is like an elevation map.  Abstract means that the data  
has no connection whatsoever to any geometrical region.  From the  
contour graphics - that I can save as a jpeg or a pdf - I would like  
to create a 3D visualization of that "landscape" and look at it from  
different points of view.  Is it possible to do something like this  
using Grass ?

Thanks ahead,

János
