taking the 'El Capitan' cliff face as an example, say I want to render two
images: object near base of, and object some distance from.  then I need to
choose a scale for the texture(s)?  I think that I (as in "numpty" etc) would
benefit from having some row/col table, in the documentation and or as array, of
all parameters involved ("lambda", "octave", such) by scale/suggested distance
(in POV-units?).  (and perhaps a macro which expands to the texture at the given
scale/index)  (just thinking aloud :-))

regards, jr.

btw, re "graveyards".  had to put on an anorak, even for a cursory read.  :-)
found out that what I associate with "granite" really is "dolerite".  thanks.
