Nothing, I think the most efficient solution is to ignore float comparisons,
much less divisions.
But create the pov file as a temporary one, and reprocess it by comparing
vertices with string functions. If a triangle has two equal vertices, it should
be removed.

something like:

##for floats:
## Almost equal.
proc ae(a, b): bool
const Epsilon = 0.000001
return abs(a - b) <= Epsilon


#for tw vac's a & b
proc ae(a,b): bool
return ae(a.x, b.x) and ae(a.y, b.y) and ae(a.z, b.z)


depending on the lang.

does not works
the triangles can to be
a.x - a.y - a.z
VS
b.y . b.z - b.a

and other cases ....
