Sorry. nx is the number of steps you take in the 'x' variable. That is, (0,
0.25, 0.5, 0.75, 1.0) would correspond to nx=5. The same goes for ny and nz.
As I said, I tested this in Matlab, so you would have to change 'x,' 'y,' and
'z,' to another name since those are reserved in POV-Ray. Other than that, the
syntax, I believe, should be okay. epsilon is just any sufficiently small
number. 1.0e-5, for example. This is because, as you ran into, 1.0 > 1.0 may
be true or false in floating point arithmetic, but 1.0 > 1.0+1e-5 will always
be false in floating point, given sufficient precision. Sorry for the
confusion.
