I would like to use something like a spline interpolation instead, which would lead to a surface not going through all those points which are far off. As far as I understand it, refine would only increase the number of points but still make sure that any data point is touched by the surface, right? > The error message refers to the number of positions/data values, not to > their dimensionality.

Thank you for pointing me the way, as I had completely misunderstood the meaning of the error message! I have got my sphere now after adding a second route behind my mark module -> include module through an unmark. So I get two data streams from the include now, one is getting directly piped into the compute's master input, while the second input's stream is first unmarked. This gives me the positions as a.x and a.y and the data as b. Perfect! I have to figure out yet how to create a nice spherical surface with the data values as delt-radius, so far I got only the showpositions to prove that the coordinate computation works. I had hoped that rubbersheet would do this, but it is only for flat carthesian positions and actually translating the data value to a elevation is already done in my compute now. So I guess I need a closer look at the isosurface module for what I want to do...? Thank you for the comments! Also Giulio has been a great help (I was not aware that my replys got addressed only to the private mail, but not the list). I can say that DX is much more fun then I was hoping for so far...
