You will need:

   - equation of the plane (representing the surface)
   - the coordinates of the atom (which you should have since you have an
   - some basic maths (from a high-school coordinate geometry section --
   both to make the equation above and work out the plane's distance from the

making the equation representing the surface and working out the remaining
maths should be relatively straightforward in VMD.
