I have yet to find a good way to programmatically carve up an image into
stained glass panes, for my own renderings I've resorted to drawing what I
want and scanning it in.

For realism I use masks of the original scanned image to 'carve' isosurfaces
into colored glass and lead objects I combine into a window. You can see two
my images that used this technique as well as some explanations and
in-progress renderings here: http://www.angelfire.com/weird2/gonk/ You can
get a good close up view of the window in the first one (Ahh Sunlight) near
the bottom of its page.

If you want to look at the code you can hunt up the IRTC entries and
download the ZIP files or e-mail me at jef### [at] twilightfaircom and I'll send
them along.
