[yt-users] calculation of distance in periodic volume

[Britton Smith]

Hi Eric,

I wrote some code to do this for the LightRay tool.  In your yt dir, have a
look at yt/analysis_modules/light_ray/light_ray.py.  Near the bottom, there
is a function called periodic_distance.  That should have what you need.
