Hello all,
             I have made a little program for windows that will convert
comma delimited ASCII files into df3 files. I have also made a very
simple df3 viewer which lets you view xy layers of a df3 file.
            The programs aren't fantastic (I'm sure someone else could
do much better), but after my own frustrations trying to find something
that would do this, I've put them on the web as freeware at
http://www.geocities.com/m_j_lewin/index.html for anyone who is
interested.

No offense but aren't they a big, err, bloated for what they do? Can
you build a version without all the MFCs or commctrls or whatever MSVC
(or VB?) uses to bloat programs?

From the screen-shots it seems they were built using MSVBasic (see the
window icons - telltale signs of VB)
I may be able to convert them to C++ - non-MFC next week

I know they're not as small as they could be, but they do the job for me. If
you need any files from me, I'd be more than happy to send them your way (I
wrote them in Visual Basic 5).

Could you make a zip file with just the exe & one with just the dlls (no
installer) available on your website as I cannot install your prog because I am
not the sys administrator on this machine and don't have write access to the
winnt\system32 directory.

If you like I could rewrite them in C++ (will make them faster & smaller believe
me) - just mail me (pab### [at] hotmailcom) the sources - I am reasonably fluent in
VB

Also would it be possible to compile greyscale tga images to a df3

This gave me the idea of making a (small and fast) utility to output
a df3 file from a f(x,y,z)-function given by the user (I even have made a
library for parsing this type of functions).
  Then I remembered that it would be a waste of time. Why would anyone use
a 3rd party program to make a coarse df3 file from a function when they can
just define a media with an isosurface function.

main(i,_){for(_?--i,main(i+2,"FhhQHFIJD|FQTITFN]zRFHhhTBFHhhTBFysdB"[i]
):5;i&&_>1;printf("%s",_-70?_&1?"[]":" ":(_=0,"\n")),_/=2);} /*- Warp -*/

Wouldn't this increase rendering speed?

  I really don't know. Isosurface functions are surprisingly fast and you
get the advantage of an almost infinitely accurate result. On the other hand
they might not be optimized for media and perhaps too many values are
calculated when less could be enough... Who knows.
  The only way of knowing would be trying. Perhaps I'll do it some day.
