The code to render height fields is strongly based upon their rectangular
shape. The way it's coded, it's able to speed up the rendering a lot just by
making use of this fact. If you distort the height field's shape, you lose
this property and the height field will render at the same speed as a mesh.
Therefore, you might as well use a mesh. You should be able to write macros
that will take a function or pigment and create any shape mesh you want from
it in a height-field like fashion.
In fact, I believe there are macros for cylindrical and spherical height
fields in the standard include files somewhere.
