@JessicaK , just to make image more demonstrative. Jump can happen even with small $\epsilon.$

comment Parabola equation in Fortune algorithm for building Voronoi diagram
@ErickWong scale-invariant, huh! i think you can form it as an answer:) Only i don't understand why they need the equation to be scale-invariant.. And why with exactly this divisor?

comment reconstruct space curve from $\kappa=\frac{a}{a^2+b^2}$ and $\tau=\frac{b}{a^2+b^2}$
Or, can you give me a link on doc on a web, i tried hardly, but can't find one :(

Please, can you say some words about a general way of finding curve equation in terms of either $s$ or $t$ if one has curvature and torsion? Thanks.
