Visualizing Fourier Maps, Crystal Structures and Magnetic Structures with DRAWxtl

Larry Finger, Geophysical Laboratory, Carnegie Institution of Washington (retired)

DRAWxtl is a free open-source computer program that can be used to generate three-dimensional images of crystal structures. Structures can be viewed and rotated in real time using openGL or VRML. Output can be provided for ray-traced (high quality) images that are rendered using the POVRAY program.

DRAWxtl can display atoms in a variety of formats, including "thermal elipsoids", balls-and-sticks and coordination polyhedra. Recent enhancements to DRAWxtl include a graphical user interface and the ability to indicate magnetic spins through use of arrows. The next release of DRAWxtl will include the ability to superimpose Fourier maps on structural representations.

DRAWxtl can be downloaded from the web (http://www.lwfinger.net/drawxtl or CCP14). Compiled versions are available for Windows, Macintosh, Linux and Silicon Graphics; the program can likely be compiled to run on many other platforms.
