In this very povray.bugreports newsgroup look for the subject "Probable 
thread safety issue in functions using splines. 3.7.0.RC7", from about a 
year back, for a complete example using a spline in an isosurface.

In your isosurface definition it also looks as if you plan to pass a 
fixed value to your spline function which would cause it to return a 
fixed value to the isosurface. This will leave you with no shape at all 
or a shape defined by the container shape depending upon the returned 
value and the threshold used in your isosurface. In other words, it is 
probably not what you want.

In addition to the built in documentation, I've found Mike William's 
tutorial at : http://www.econym.demon.co.uk/isotut/index.htm helpful.
