GNU 3DLDF is a software package for three-dimensional drawing with MetaPost and METAFONT output. The program 3dldf implements an interactive language similar to the METAFONT and MetaPost languages.
2026.02.15.
PLEASE NOTE: Due to lack of traffic, I do not update these web pages regularly.
However, I do continue to develop the package and update the GIT repository (see below)
very often, in fact, almost daily.
The best source for information on current developments are the logs for the source files
in the Git repository. These may be easily viewed by using the web interface at Savannah
(see below).

GNU 3DLDF 2.0.3 can be downloaded from
ftp://ftp.gwdg.de/pub/gnu/3dldf/
Alternatively, http://ftpmirror.gnu.org/3dldf/
will automatically redirect to a nearby mirror.
The source code, including developments since the latest release,
is also available from the Git repository for project at Savannah:
git clone git://git.savannah.gnu.org/3dldf.git
This news not old enough for you? Then try some Even Older News.
The complete current sources can be obtained from the
Git repository
for the 3DLDF project
on the GNU Project's
software development site Savannah.

The most recent version of the GNU 3DLDF manual (see below) documents Release 1.1.5.1.
I need to rewrite it completely in order to account for the many changes I've made in
my development versions. I have been
documenting the latter on these web pages. The old manual may still be of use to
people who want to know how 3DLDF is implemented, but it is quite out-of-date
by now.

I've abandoned work on the
GNU 3DLDF 1.2.0 Manual --- Plain Text Version
(Last updated 2005-01-31).
I now plan to convert it to Texinfo. Until I do, however, it may
still be useful to people who want to learn how to use
3DLDF 1.2.0.
The downloadable versions of 3DLDF: The Program, and the versions in the distribution have the table of contents at the front. This is not the case, if you generate them yourself. In order to do this, I used dviselect and dviconcat. I have not yet written make rules to do have this done automatically.

I've replaced @
with -*-AT-*-
in all of the email
addresses on these webpages, and removed all clickable references to
email addresses. I've been forced to this step by the huge amounts of
spam I receive.

I have reactivated the
help-3dldf-*-AT-*-gnu.org
mailing list, but only for subscribers. Postings from non-subscribers
are automatically discarded. I have deactivated the other GNU 3DLDF
mailing lists.
I have been forced to take this step by the huge amounts of spam
posted to these lists.
For the same reason, I've also replaced
