[yt-users] transparency and color from two arrays

Hi Zbyněk,

Sorry for the delay in replying!

This is possible; it isn't super duper easy right now, though.  What you'll
have to do is manually set up a transfer function using
ColorTransferFunction.  This has the option to set multiple fields, and
multiple alphas; you'll then tie field interpolation tables to different
fields, along with alpha.

It's not ... super duper easy right now.  If you look at how the
PlanckTransferFunction is set up, you can see how this is used to have
temperature specify the color and density the emissivity and alpha.

I wish I had a better answer!
