hmm.. odd thought. You know what would be interesting to have in POV? A
scale_map function definable in the X, Y, or Z direction, that you could
use on objects from spheres, to CSG's, to isosurfaces. I'm talking about
being able to do this without having to revert to converting to meshes
of triangles.

ie:

sphere {0,1
 pigment {rgb <1,0,0>}
 finish {specular 0.3 roughness 0.03}
 scale_map y {
  [0.0 <1.00, 1.00>]
  [0.3 <3.50, 0.75>]
  [0.7 <0.50, 2.12>]
  [1.0 <1.00, 1.00>]
 }
}
