Grany-3. The cellular automaton simulator. [ download ] [ faq ] [ screenshots ]

Because we wanted to use state-of-the-art free software tools, it rapidly became important to me to produce a freshmeat release, in order to spread the software.

Grany-3 can be useful to you if you are...

• a granular media physicist, because we believe it's full-featured to simulate valuable situations ; special screenshots to prove it ;
• a computer folk interested in free software projects, because we used lots of nice tools:
  • language used is C++, and we tried our best to have a good OO design: we could achieve a /total/ independance between the engine, the files, and the graphical user interface,
  • Gtkmm for the graphical user interface (this is the main C++ binding of the well-known GTK+),
  • flex++ and bison++ for file handling,
  • Doxygen for autogeneration of code documentation,
  • GNU gettext for internationalization,
  • autoconf and automake to make the configuration automagic.

Quick requirement:

• A good `make' program. Preferably use GNU Make (see here) but at my suprise I could make grany-0.9.1 with the default make coming with a SunOS 5.5 sun4m (ie a Solaris 2.5 system).

• A good C++ compiler. We used GNU egcs 1.1.x from Cygnus (now you can get gcc-3.2). Warning Grany won't compile with gcc-2.7.x or gcc-2.8.x Get a good compiler?

• The Gimp Toolkit : grany-2.0.0 uses gtk+-2.2 and its C++ binding called gtkmm-2.2 (formerly called Gtk--). Get it?

If these software aren't installed on your machine, you'll only have to freely download them (they're under GNU licence) and install them.

I would like to see some screenshots of the graphical user interface.

Quick! Take me to the download section!

• 2003-04-08: fifth official release, version 2.0.0.

  Compatible with gtkmm-2.2 API.

• 2002-05-14: fourth official release, version 1.0.1.

  Compatible with g++-3.1.

• 2000-08-14: third official release, version 1.0.0.

  Stabilization release. Now compatible with gtkmm-1.2 API.

• 1999-08-30: second official release, version 0.9.1.

  It's basically a bunch of minor improvements, and some medium-urgency bugfixes.

• 1999-08-07: first official release, version 0.9.

  It has been tested on Sparc/Solaris 2.5, UltraSparc, PC/Gnu/Linux, and Alpha/Gnu/Linux platforms, but it should work on any platform where GTK has been ported, including PC/Microsoft/Windows. An automatic configuration process "à la GNU" makes the things very easy.

• 1999-06-18: official end of our University project.

  But the program is not yet usable, and it's a pity because it's 5% more work from beeing usable. I'll take some time to bring a correct version to the Internet.

• 1998-09-25: official start of our University project.

  We don't know yet that the project will lead to a free software release, but we're 7 young french computer science students and we want to do our best!
