One more tidbit of information: You can turn the files into ASCII XML
using command line tool "plutil -convert xml1 [filename]" and edit
them in a text editor. QC will also open the ASCII XML files but when
you save them, it will turn them back into binary.

So, I've had a look, and as Ben has pointed out, the Compositions
are indeed binary xml. Their structure is not entirely straight
forward, but it would seem simple enough to write some custom code
to add elements to an existing template composition. This should
suffice for my purposes (basically, adding more spheres/cylinders
inside a trackball patch), but it would still be nice to have
either an API or at the very least some documentation so that
compositions could be created from scratch. I have submitted a
feature request (rdar://4971181) summarizing these requirements.
Here's hoping that Quartz Composer just keeps getting better and
better!
Cheers!

Hi,
from my guess Quartz Compositions are just binary xml files. You
can open them with the Property List Editor. I haven't tried yet
to create my own .qtz this way, but if you do, please post your
results.

Hi,
I tried a search through the mailing list, the dev docs, and on-
line, but couldn't find a definitive yes or no, so I thought I'd
pose the question to this list:
Is it possible to create a Quartz Composition in code?
I already understand how to publish ports and control a
composition in code, but this is not exactly what I'm looking for
(though, I suppose with a creative enough composition I could
potentially achieve the same results). Basically, I'm looking to
use QC as a shortcut for drawing some simple shapes in space and
moving them around. The issue is that I'd like to determine how
many shapes, their sizes, and their positions at runtime. In
other words, I'd like to not have to code the raw GL! ;-)
So, does anyone know if this is possible? Thanks in advance for
any help and/or advice!
Cheers,
Josh
