This is Gmsh, an automatic three-dimensional finite element mesh generator, primarily Delaunay, with built-in pre- and post-processing facilities. To install Gmsh, type ./configure make make install This requires GSL 1.2 or higher (freely available from http://sources.redhat.com/gsl/) and FLTK 1.1.x (configured with OpenGL support; freely available from http://www.fltk.org). You can use the --with-fltk-prefix and --with-gsl-prefix configure options (or define the FLTK_PREFIX and GSL_PREFIX environment variables) if the libraries are not installed in their default locations. Please note that compiling the Windows version requires the Cygwin tools (freely available from http://www.cygwin.com) and a "cygwin-enabled" version of FLTK (i.e., you have to configure FLTK with "./configure --enable-cygwin"). To install a non-graphical version of Gmsh (that does not require FLTK nor OpenGL), type ./configure --disable-gui make make install For a description of all other configuration options, type ./configure --help Gmsh is distributed under the terms of the GNU General Public License.

The current behavior of Gmsh when drawing 3D scalar fields is not coherent with what is done in 2D: to draw filled iso-values or continuous maps in 3D, we should ideally do volume rendering. Right now we draw the iso-values (i.e., surfaces), which is both not coherent with the definition of continuous maps or filled iso-values, but is also annoying when trying to visualize fields that are constant per element (since in that case nothing is displayed!) Until we can do volume rendering, I've changed the behavior to draw the solution on the boundary of the 3D elements. It's rather slow, but it's the right thing to do visually.
