Quadratic differentials genericaly have vertices with 3-way branching, they give whole families of line (much like the foliation $f^{-1}$ of lines parallel to the real or imaginary axis), and the measurements of distances are immportant. | |

| Dec 24, 2010 at 7:42 | comment | added | j.c. | Have you looked at the literature on quadratic differentials? Not having engaged it better, I can't write an answer, but the x-ray seems to be similar to the notion of "positive" and "negative" trajectories of a quadratic differential. See e.g. eom.springer.de/q/q076040.htm | |
