Hi Bill,

I have never used DF3 files before but now see I need to read up on them as I
did not realise you could control the shape of a cloud in this way.

Are there any good resources you can point me to?

Thanks

Sean

This gives me the shivers! ;-)

Very nicely done; like Sean, I need to read up on df3 creation. I have 
used them for clouds of course (Gilles Tran) and as proximity pattern 
holders, but those are generated out of my control so to speak. Now 
/this/ is a different story altogether.

A few years ago, I created an animation scene which intersected an object with a

with tga2df3. A bit like a Tomography scan. I used three filters on the

meshes but solid objects are better.
A short animation is posted here:

The object is a cubic Mandelbrot (code posted by Andrew) from an angle that I
never found again.

A creepy scene ;-)

Yes, that is how I understand the making of. Never done it myself but I 
see the potentials. Much to do...

Hi Sean,
After work today I'll post more if I find the time. Take a look at the 
thread "interesting shape: CA, DF3, isosurface (284k jpg)" started by 
Sam. He used C++ code Warp put together, but to which I do not have a 
reference handy.

Unsure if this link will work as pasted but :

http://news.povray.org/povray.binaries.images/thread/%3C4a28719b%241%40news.povray.org%3E/

Anyway, in that thread there is a message from Darren about his MakeDF3 
tcl utility which he posted to p.b.utilities. I know tcl, so in the end 
used my own version of tcl code, but this utility is where I started. It 
is the only general utility for manipulating DF3s I know aside from 
Gilles's make cloud approach.

Aside: Povray 3.7 itself might be able to write the df3 file format as I 
know it can now write most others, but wasn't the route I took.

Look too in the documentation & scenes files for a couple of small 
examples using provided df3 files. There is one "star" one for a simple 
cloud shape.

Creepy!

Just recently I developed a new way to convert any (supported) object into a
volumetric pattern, and it doesn't use df3 files. The idea is to render an
animation of a proximity pattern (each frame = one slice), and then combine all
the frames into a gradient z pigment_pattern in another scene file.

Attached is an example of a mesh (modeled in Sculptris+Blender) converted in
this manner, given a displacement pattern, and rendered as an isosurface. I've
made the process as painless as possible, and will try to post the source later
for anyone who is interested in looking at it.

Interesting. I look forward to seeing the source

And here's a shot of the isosurface, sans displacement (the original mesh looks
nearly identical, so I won't post a picture of it).
