Crystal Movies : View HERE

These are animated gif files that show crystal structures evolving as a function of pressure, temperature, chemistry, or orientation. A reference for creating these movies is:

XtalDraw: (Version January 23, 2004, contains updated XPow)

XtalDraw is interactive Windows-based software that draws crystal and molecular structures as ball and stick, polyhedral, and thermal ellipsoid representations. It comes with a large set of datafiles. Not only does it read the XtalDraw datafiles, but it can also read the American Mineralogist Crystal Structure DataBase datafiles. Download! This version of the software can also launch XPow when *.amc files have been read, so you do not need to download the XPow software. Gallery of images.

XPow: (Version January 23, 2004)

XPow is a program that plots theoretical diffraction patterns of crystalline materials in a Win95/98/NT enviroment. It reads datafiles with extension *.pow as well as the *.amc files from the American Mineralogist Crystal Structure Database . Download the executable and sample datafiles .
