  The conversion program I mentioned is in the binaries utilities
group. It was posted 09-04-1999 by PoD. The source code is also
posted with the executable for those wishing to compile for a
different operating system.

What kind of tgas would you generate?

Would you post it here? I don't feel like sorting through pov.binaries.

I thought that  the *.df3 files were some sort of 3 Dimensional file?,
are you saying that a density is
a 2-d Bit map? Please Post the File.

Thank you for your help

Think about it this way:

Greyscale Bitmap: 256x256 256 shades of grey

the bitmap X and Y are the DF3's X and Y.

The color value (0,0,0 to 255,255,255) of the pixel at any given point is
the Z value for that point.

  I don't know as I have not explored this aspect of Pov yet. As far
as I know the utility reads in a series of 2d uncompressed .tga files
and produces one 3d .df3 media density file. How many it needs and
what it looks like is an exersize I will leave to the reader of this
message to discover for themselves.

Try this link to see if you can dowmload the file. It is a pointer
to the file in the povray.binaries.utilities group. I won't post
binaries here because it is not binaries group. If the link does not
work you will have to find it on your own sorry.

Does this mean, in theory, that we could just use the same images we use for a
heigtfield, and get a similar effect?

Does anyone have a Sample DF3 & source TGA's so that i can better
understand the concept and what the TGA's Should look
like to produce certain results? Thank you everyone for trying to answer
my question Especially Twyst.

That does not compute. A DF3 is 3 dimensional file, that is a value for each
<X,Y,Z>, not each <X,Y>. You would need the same number af TGAs as you have
Z layers in your file.

<shrug> that's how I understood it -- I could be wrong - I've never used a
DF3 file. (but there are people who have... )

i want to make a Nuclear Explosion using DF3 i think that it might make
a very good Mushroom cloud.
I've tried to use real pics of the bomb test and  a 4 frame animation
but i'm getting odd results, the density ends up looking
nothing like the pics that i used . any suggestions???
