Dear Peter and Christopher,

thank you very much for your help. I try to clear up the misunderstanding:

I've calculated a data field with a scientific program. For
each point (x,y,z) in space I've got a value, for example
a temperature.

What I want is a plot with all points of the same value,
which built up an isosurface. I didn't mean the function
"isosurface" of povray, because I don't have an algebr.
function, but experimental respectively otherwise calculated
data points.


Example:

Today I've found a solution of Mr. Suzuki, who wrote his own
library file:

-------------------------------------------------------
   equpotsurface
   {
      box <1, 1, 1> <9.0, 9.0, 9.0>
      eval
      library   "ep_dat3d","test1.dat", <10,10,10,0>
      function       "data_3D_3", <1.0> // 3rd order intp.
//     function  "data_3D_1",<1.>   // 1st order intp.
//     max_gradient 1.4
      threshold -0.3
      ...
    }
-------------------------------------------------------

So I could use the povray-version together with the extensions
of Mr. Suzuki - or one of you knows a solution with povray 3.5...


Again: Thank you very much!
