Ok, my wording was not mathematically accurate.
What I was trying to say was that a cylinder of 1 meter at the origin can
be very accurately expressed, but the same cylinder at a distance of
10^100 from the origin will not likely to be exactly 1 meter long because
of accuracy problems.
This means, for example, that if you are modelling the solar system
with accurate distances and using 1 povray unit as 1 meter, and then you
sloooowly rotate the Earth around the Sun, it will most probably move in
jumps.
And this of course regardless of your epsilon.
