VisuDomain
==========

     VisuDomain consists of as an extension to the PolyLib that permits to visualize
     union of parameterized domains (you can use it to visualize single
     non-parameterized polyhedra too of course).

     The GTK/VisuDomain package contains :
     o the GUI that permits the visualization : the executable is visudomain
     o this file (README)

     visudomain reads polyhedra descriptions from stdin. 
     Thus, a typical execution is 
	 	"visudomain < t3.in".
     where 't3.in' is a polydra description file.

     Input format is similar to the Polylib format.

	 More examples are shipped with Polylib (http://icps.u-strasbg.fr/polylib)
	 As the polylib should be installed to run visudomain, you shoud
	 find the examples in
	 ${prefix}/doc/packages/polylib-${ver}/examples/ehrhart/
	 where
	 ${prefix} is /usr or /usr/local depending where you installed
	 ${ver} is the version number , e.g 4.20
	 In that directory, only the .in files are suited as visudomain inputs.

    USAGE
          The main window displays your polyhedron, once valid parameters
          have been given, if there are any. 
          You can change their values at anytime and the domain will be 
          dynamically redrawn.

          You can print the coordinates of any integer point in the
          polyhedron by clicking on it.

          The 'View Projection' button opens a secondary window which
          permits to change the view of the domain by moving the axes.

          Guess what the 'Quit' button does.

     
    PACKAGES 

          I will try to maintain RPM packages for the main Linux distributions,
          and if you cannot find any package suiting your installation, you can
          get the source tar ball at http://icps.u-strasbg.fr/polylib .
          Unless many people ask for it, i won't build packages for VisuDomain
          for XView.  
          

If you have problems with this package, contact me (genaud@icps.u-strasbg.fr)
