Hello.

I want to make an orange (in povray, of course. otherwise, i could buy it in
the next supermarket ;). However, for an orange the bumpsy skin is
important, so I dont want to work with normal, but with isosurfaces. A pity
I dont like function-formulars, and so I need help: Is there a way to make
this Lathe:

lathe { bezier_spline
    4,  <0,0.3>, <0.4,0>, <0.75,1.3>, <0, 0.95>}

become an isosurface?

Thx in advance.

Well, a lathe seems like a very poor choice of a shape for an orange. 
And creating a lathe isosurface would be pretty difficult. Really, the 
best shape to use for this is just an isosurface based on a sphere 
function.
