NAME

       iorheo - input and output functions and manipulation

SMALL PIECES OF CODE

       input geo in standard file format:

               cin >> g;

       output geo in standard file format:

               cout << g;

       output geo in gnuplot format:

               cout << gnuplot << g;

DESCRIPTION

       output manipulators enable the selection of some pretty graphic options, in an elegant fashion.

BOOLEAN MANIPULATORS

The boolean manipulators set an internal optional flag. Each option has its negative counterpart, as
verbose and noverbose, by adding the no prefix.

cout << noverbose << a;

verbose
trace some details, such as loading, storing or unix command operations on cerr. Default is on.

clean delete temporary files during graphic outputs. Default is on.

execute
run unix operations, such as gnuplot or plotmtv or vtk. Note that the corresponding files are
created. Default is on.

transpose
perform transposition when loading/soring a csr matrix from Harwell-Boeing file. This feature is
available, since the file format store matrix in transposed format. Default is off.

logscale
when using matrix sparse postscript plot manipulator ps and color. The color scale is related to a
logarithmic scale.

split when using the vtk or mayavi manipulators for a mesh or a field.

volume volume rendering by using ray cast functions.

velocity

deformation
Vector-valued fields are rendered by using arrows (velocity) or deformed meshes (deformation).
For vtk or plotmtv rendering.

elevation
Scalar valued fields in two dimension are rendered by using a tridimensionnal surface elevation.
For vtk or plotmtv rendering.

fastfieldload
try to reuse the supplied space. Default is on.

FILE FORMAT MANIPULATORS

The format manipulator group applies for streams. Its value is an enumerated type, containing the
following possibilities:

rheo use the default textual input/output file format. For instance, this is `.geo' for meshes,
`.field' for discretized functions. This default format is specified in the corresponding class
documentation (see also geo(2) and field(2)). This is the default.

bamg uses `.bamg' Frederic Hecht's bidimensional anisotropic mesh generator file format for geo
input/output operation.

tetgen uses `.node' `.ele' and .face Hang Si's tridimensional mesh generator file format for geo
input/output operation.

mmg3d uses `.mmg3d' Cecile Dobrzynski's tridimensional anisotropic mesh generator file format for geo
input/output operation.

gmsh uses `.gmsh' gmsh Christophe Geuzaine and Jean-Francois Remacle mesh generator file format for geo
input/output operation.

gmsh_pos
uses `.gmsh_pos' gmsh Christophe Geuzaine and Jean-Francois Remacle mesh metric file format for
geo adapt input/output operation.

grummp uses `.m' (bidimensional) or `.v' (tridimensionnal) Carl Ollivier-Gooch 's mesh generator file
format for geo input/output operation.

qmg uses `.qmg' Stephen A. Vavasis's mesh generator file format for geo input/output operation.

vtkdata
uses `.vtk' mesh file format for geo input/output operations. This file format is suitable for
graphic treatment.

vtkpolydata
uses `.vtk' polydata (specific for polygonal boundaries) mesh file format for geo input/output
operations. This file format is suitable for graphic treatment.

cemagref
uses `.cemagref' surface mesh (topography, with a z cote). This file format is used at Cemagref
(french research center for mountains, http://www.cemagref.fr).

dump output an extensive listing of the class data structure. This option is used for debugging
purpose.

hb uses `.hb' Harwell-Boeing file format for sparse matrix input/output operation. This is the
default.

matrix_market
uses `.mm' Matrix-Market file format for sparse matrix input/output operation.

matlab uses `.m' Matlab file format for sparse matrix output operation.

sparse_matlab
uses `.m' Matlab sparse file format for sparse matrix output operation.

ps uses `.ps' postscript for sparse matrix output operation.

vtk for mesh and field outputs. Generate `.vtk' data file and the `.tcl' command script file and run
the vtk command on the `.tcl'.

mayavi for field outputs. Generate `.vtk' data file and the `.py' command script file and run the python
command on the `.py' associated to the mayavi/vtk library.

geomview
for boundary cad outputs. Generate `.off' data file and run the geomview command.

gnuplot
for mesh and field outputs. Generate `.gdat' data file and the `.plot' command script file and
run the gnuplot command on the `.plot'.

plotmtv
for mesh and field outputs. Generate `.mtv' data file and run the plotmtv command.

x3d for mesh output. Generate `.x3d' data file and run the x3d command. This tool has fast rotation
rendering.

atom for mesh output. Generate `.atom' data file and run the PlotM command. Tridimensional mesh
rendering is performed as a chemical molecule: nodes as balls and edges as tubes. The PlotM tool
is developped at Cornell University Laboratory of Atomic and Solid State Physics (LASSP) in a
Joint Study with IBM, with support by the Materials Science Center and Corning Glassworks.

COLOR MANIPULATORS

       The  color  manipulator  group acts for sparse matrix postscript output. Its value is an enumerated type,
       containing three possibilities:

               cout << color << a;
               cout << gray  << b;
               cout << black_and_white  << c;

       The default is to generate a color postcript file.  Conversely, its act for field rendering, via mayavi.

VALUATED MANIPULATORS

       Some manipulators takes an agument that specifies a value.

               cout << geomview << bezieradapt << subdivide(5) << my_cad_boundary;
               cout << vtk << iso << isovalue(2.5) << my_mesh;
               cout << velocity << plotmtv << vectorscale(0.1) << uh;

       See also catchmark(4) for input-output of vector-valued fields.

       isovalue float

       n_isovalue int

       n_isovalue_negative int

       vectorscale float

       subdivide float

       image_format string
              The argument is any valid image format, such as png, jpg or pdf, that  could  be  handled  by  the
              corresponding graphic render.
