Hi all,

After a lot of hard work from Matt and Jeff, yt now has the capability 
to generate multivariate volume renderings.  Lately Matt added Rayleigh 
scattering to the ray tracer, which produces superb results in some of 
these renderings.  I just wanted to showcase a couple of renderings to 
show what's possible with it.

Reionization simulation at redshift 8.5 in a 12.5 Mpc/h box with 512^3 
resolution, unigrid.  10^6 solar mass dark matter resolution.

Dwarf galaxies forming in a pre-heated medium at redshift 17.  The 
clouds are on the order of 10^7 solar masses.  The simulation considers 
radiative feedback from Pop III stars and their remnant black holes.

Cheers,
John
