Wrong term, I should have used "baked". In CGI, that's taking simulated data
and writing it to disk, e.g. shadowmaps from Global Illumination simulations
etc.

That's what I was after.

Sounds interesting. I guess the technique you might be using is somewhat
related to the different image-formats to reduce the amount of data. From
that perspective, the DF3 we use now might be considered a Bitmap, where
you're going for PNG. Well, PNG might not be it, since it saves the used
colors beforeend... But you get the idea, I hope.

I think that your EDF might be a good development for POV-Ray, since it'd
make larger Density-Files possible whilst using less disk-/RAM-space. So, by
all means, go ahead and do it! :-)
