| Hi Pilou,The X, Y, and Z can be functions of u and v.
 So X = sin(u) would be one example. Y = cos(v), Z = sqrt(something)...
 Or more complex equations.
 
 Check out the Macro's, which are likely from James:
 mobius, offsetGrid, sineSurf, waveSurf, quadSpheres.
 
 It would be nice to find a really cool example.
 Maybe a curvy surface in 3d...
