drawxtl - display crystal structures on ordinary computer hardware


drawxtl [filename]


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


There are no command line options to use.


Per user configuration file.

A short tutorial about this file and configuring drawxtl is available online at


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.").


A FAQ and a manual are available online in PDF and HTML format at the DRAWxtl homepage at
