NAME

       drawxtl - display crystal structures on ordinary computer hardware

SYNOPSIS

       drawxtl [filename]

DESCRIPTION

       drawxtl  reads  a  basic description of the crystal structure, which includes unit-cell parameters, space
       group, atomic coordinates, thermal parameters or a Fourier  map,  and  outputs  a  geometry  object  that
       contains  polyhedra,  planes, lone-pair cones, spheres or ellipsoids, bonds, iso-surface Fourier contours
       and the unit-cell boundary.

       Four forms of graphics are produced:

       •   an OpenGL window for immediate viewing

       •   the Persistence of Vision Ray Tracer (POV-RAY) scene language for publication-quality drawings

       •   the Virtual Reality Modeling Language (VRML) for dissemination across the Internet

       •   Postscript rendering of the OpenGL window for those who want high-quality output but do not have POV-
           RAY installed

OPTIONS

       There are no command line options to use.

FILES

       ~/.drawxtlrc
              Per user configuration file.

       A    short    tutorial   about   this   file   and   configuring   drawxtl   is   available   online   at
       http://home.att.net/~larry.finger/drawxtl/configure.htm.

BUGS

       When opening a structures (.str) file, drawxtl needs write permissions  in  the  directory  the  file  is
       located in. Otherwise it will return an error ("Cannot open structures files.").
