                                                          - Warp
isosurface{ // sphere
 function{ sqrt(x*x + y*y + z*z) - 1 }

isosurface{ // cylinder
  function {  sqrt(x*x + z*z) - 1 }

isosurface{ // my spline-based object (Object on the basis of a spline)
  function {  ????????? } //User-Defined Function. How?
