Ah, than this bit of code:
value = ((value > 1.0) ? fmod(value, 1.0) : value);
will cause you some problems...it shouldn't make an error though, it
will just make it repeat the [0, 1] range.
I'm thinking of modifying the pattern feature to allow values outside of
[0, 1] to let these "special cases" work properly, it shouldn't be a big
problem for older scenes. Also, I did write up a bit of code for
allowing functions to be evaluated directly, but I never tested it. I
posted it here or in povray.programming...maybe I will get back to work
on it.
