[Yt-dev] The DTFE Method

Hi all,

A paper, and affiliated GPL-licensed public code, was posted today
that may be of interest:

http://arxiv.org/abs/1105.0370
http://www.astro.rug.nl/~voronoi/DTFE/dtfe.html

The paper itself has examples for gridding SPH particles, and it is
OpenMP parallel.  This could be the basis for an interesting mechanism
for loading SPH data; one could imagine the initial procedure being
decomposition based on a fairly coarse PH-curve (allowing for overlap
between processors), feeding individual regions to the DTFE, and then
gridding them.  It also includes TSC as well as SPH interpolation.

This could also be useful for a variety of other gridding processes
that yt does.
