This is very interesting. On a first read through though, I'm still not entirely clear what they're doing. First of all, I am not sure how they account for the redshift evolution of portions of the universe further away. Certainly the main goals (not using any part of the volume more than once, preserving the periodicity of the box) are important, and can be difficult to solve. I need to read through this carefully to see how this could be used for our light cones. On Mar 16, 2010, at 10:30 PM, Matthew Turk wrote:
Hi guys,
There was a paper on the arxiv today,
http://arxiv.org/abs/1003.3178
about remapping cubical, periodic volumes into non-cubical volumes -- suitable for things like light cones and whatnot. The group provides code as well as further description here:

I wonder if this could be used as an enhancement in the light cone extension? Britton, Eric, what are your thoughts?
