More seriously, as I was just searching through the Lugnet archives for
further incriminating evidence that I’ve sort of been
reinventing the wheel with
Bitsticker, I came upon this thread by Tim Gould from 2005:
Automatic sticker creation. That is
clearly a more practical implementation of an image-to-LDraw converter! Has
that been released? More to the point, I’m simply curious about how the
vectorization is achieved. This comment in particular is right on:
| |
The advantage this has over BMP2DAT (from what I can gather, haven’t
really used it) is that my program finds the lines and then triangulates
the resulting polygon rather than turning pixels into quads (correct me if
this is not what BMP2DAT does).
|
Does it use a library like potrace or did
you write your own vectorization code? (I’ve done a lot of work with remote
sensing and GIS so vectorization is just a fascinating topic to me.)
Hopefully I have just overlooked some more recent announcement pertaining
to this project.
Thanks,
Jim

Unfortunately I got too busy with other things and kind of let is slide.
With a rewrite in a compiled language and using a decent triangulation (such
as the one Ross uses) and vectorisation algorithm I suspect it could be made
to work better.

Hmmm. It would appear that using the Potrace API and the Triangle API would
do almost all the difficult work for software of this sort. I might look into
restarting the project although I’m not sure how far I could get with it. Of
course if anyone would like to take it over I’d be willing to offer as much
help (including source code) as I could.

Neat. I have also
used
autotrace, a similar program. I haven’t
used either enough to recommend one over the other, but for some reason I do
recall preferring potrace’s output. (I’ve only used the programs, not programmed
with them.)
I don’t know how much use people would find for it (the same applies to
Bitsticker), but personally I think this would be a really cool program. I can’t
offer to take it over, but as with a couple other LDraw programs I’ve had my
fingers in recently, I’d be glad to help test it out.
Take care,
Jim
