  Perhaps something similar to how you can construct a heightfield from
a function without having to use a temporary file?

  In fact, this principle could be applied to many other things, such as
creating image maps procedurally without having to create an image file.

  (Of course all this should be achievable trivially in the hypothetical
scripting language of POV-Ray 4, but it seems that that issue has been more
or less put to rest for the foreseeable future, as there will be no such
new scripting language anytime soon, and instead the current language will
be kept being expanded for a long time.)

yes, I noticed this at the edges where is transitions abruptly to 0.
