I need help in creating DF3 files to make a Mushroom Cloud caused by an
Nuclear Explosion i've tried to experiment with the DF3's but no success
on creating any thing close to what i wanted or expected. If anyone
knows "ANYTHING" about the elusive DF3's please tell me.  I'm still
quite new to pov ( maybe one year under my belt ) so, please try to
explain it to me as if i were a 2 year old.

Thank you for your time reading this,

I am leaving town for a few days, but I would be happy to give you what
help I can when I return.  In actuality, I think Jim Kress probably has
more experience with DF3's than I do.  I just dissected them.

Send me an email and I'll see what I can do when I return

What is DF3?

Roughly interperated I believe it means 3D density file. There is an
option in pov that will allow you to use a .df3 file as a way to control
the density function inside a media. It has other uses as well but this
was it's primary intended purpose. There is a utility that will allow
you to take one or several .tga image(s) and create a binary .df3 file.
The black art involved with knowing what to feed the conversion utility
is what this thread hopefully will answer for us all. I am skeptical that
anyone really knows to be perfectly honest with you and I sit patiently
on the side waiting for this revelation to unfold.

Attached is a five I've successfully used to generate several .df3s
out of csg-able objects - a keyboard, the word POV, a julia fractal, a
torus (with some turbulence makes a really good pipe smoke ring). Just
declare the object you need converted and render an animation. The
object bust fit into the unit box and must be csg-able. Frames must be
of square shape. It takes a lot of tweaking to get a complex object to
fit into the unit cube, but if you have the superpatch, a simple macro
using min_extent and max_extent could do the trick. For now, I hopw
this is useful as is.

I couldn't help but notice the "CSG-able" word said. I wanted a DF3 of a
complex model once and came up with mixed results. Basically it didn't
work in other words (although it almost did it seemed), and I repeatedly
got a "patch object not allowed" during parse as I tried in vain to get
the model sliced up right.
So I guess this is impossible? No work-arounds? Well, I'm not giving up.

It depends on how you want to create the df3 file.  there have been several
posts in the povray newsgroups about utilities that create a df3 file from
various types of images.

I've written some code to take a 3D array of x,y,z data and from that
directly create a df3 file.  If anyone is interested, I can clean it up and
post a copy in the binaries.utilities group.

If you have the Superpatch you could use trace() to do what you're wanting
to do.  In fact, you could write a macro that takes an object, a filename,
and the desired resolution and automatically creates the df3 file for you.  
It wouldn't be the fastest thing on Earth, but it wouldn't be too terrible.

Oh wow, hey, that might work huh? Thanks for the new incentive, and the
S.P.
Gee, is nothing impossible...? If you see a DF3-made image at
binaries.images later on you will know I succeeded.
