Re: [yt-users] calculation of distance in periodic volume
This is hilarious, because there is also one in yt/utilities/math_utils.py. I wonder which one is better? :) Stephen Skory stephenskory@yahoo.com http://stephenskory.com/ 510.621.3687 (google voice)

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.

Hey,
I am wondering if there is a simple routine in yt for calculating the minimum distance between two points in a periodic volume. Somehow I wind up writing a new routine for this every time I do it, and it requires a bunch of loops to check which distance is right. There is bound to be a faster easier way, wondering if anyone knows of one in yt, or has one they use that works fast.
thanks!

Hi all, I think it's worthwhile to reduce the number of points-of-failure we have in the code. I think we should remove the light_ray periodic distance and move to using the math_utils.py one. My reading is that that one is better documented, covers a few more potential corner cases, and I generally prefer we standardize on the one that's global rather than specific to an individual analysis package. -Matt On Tue, Nov 30, 2010 at 10:14 AM, Stephen Skory <stephenskory@yahoo.com> wrote:
