Is there documentation on how to use height fields with a function?
I've looked at the example file, but I can't find any information
about this in the documentation.

This is with version 3.5 final...

  See the section 6.7.11.16 of the POV-Ray documentation.
  You can use a function image to create a heightfield.

Thanks, didn't think to look for it there.
