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.
Bill P.
