I really would like to be able to use an image as a pattern without having
to create a df3 file first. Something like:

pigment {density_file tga "filename.tga" [interpolate Type]
[PIGMENT_MODIFIERS...] }

From the POV-Ray documentation:
"The syntax provides for the possibility of implementing other formats in
the future."

I hope other formats will be implemented then.

Until then, is there a program that can convert an image (tga, png, or
something) into a df3? I know of Df3Maker, but that's not what I need here.

Greetings,

Rune

You can use an image as a pattern already, in MegaPOV. There are at 
least 3 ways: image_pattern, pigment_pattern with an image_map pigment, 
pigment function pattern with an image_map...

I think it would be more useful to allow a "stack" image or a group of 
images to be used directly. Movie formats would also make good 
additions. Like this:
density_file {tga list N
    "filename1.tga",
    "filename2.tga",
    "filename3.tga",
...
    "filenameN.tga"
    [interpolate Type]
}


density_file {qt_moov|mpeg|avi "MovieFile.mov"
    [interpolate Type]
}

Also, it might be nice to have movie formats as ordinary image types... 
you could specify the frame number or time(with 1 being the last frame, 
and 0 being the first frame). It would be an easy way to animate 
image_maps.

image_map {qt_moov "MyMovie.mov" time 0.7*clock | frame int(15*clock)...

How about supporting different codecs on different platforms?

Ah yes, image_pattern was what I needed. I had forgot about that one...

However, I still think it is a bit redundant to have two different syntax
that could do basically the same things.

Right now I have found a better solution, but your program sure sounds
interesting, so I'll probably have a look at it another time. :-)

Thank you!

I also went to PoD's homepage, but I only got a blank page. Anybody knows
why?

Odd, I just checked it and it's there. The df3 thing isn't there though.
I haven't touched that page for ages, I really should get off my arse
and do a new one.

I still get a blank page. I used http://pod.phong.com/ as listed in the
links at povray.org.
Should I use another address (in which case the link at povray.org should
also be updated)?

Yes, that would be great! :-)
