CrystalView 1.0 is a unit cell drawing Mac application written
and compiled in Microsoft Quickbasic. It was written as an
educational tool. One enters the crystal coordinates, screen dimension
and color of each atom in the basis group, and defines the unit
cell shape and centering (primitive, body-, base- or face-centering)
independently of basis group. The cell can be viewed in orthonormal
projection from any direction by moving the mouse around in a
stereo projection circle, or by typing in indices. Drawings
can be printed, or copied to the clipboard. Since this was
written as an educational tool, there is a facility for hiding
any desired atoms of the basis group so one can view the configuration
of a subset of atoms, say the oxygens in spinel or interior atoms
in GaAs. One can attach a tetrahedron to a group of atoms,
but I have never finished a more complete facility for adding other
construction lines.Crystal 2.29 is a stererographic projection Mac application, also written and compiled in Microsoft Quickbasic. It draws projections for any crystal system, with great circles as desired. It has a number of utilities, including one which can be used to solve back-reflection Laue patterns. I developed it for use in a Cullity-based x-ray course, and marketed it as a "commercial" product for a few years. I have now made it public domain.
Given the interest expressed now on Internet, I am trying to find a file server on which both applications can be made widely available. I will post a message on the Sci.Techniques.Xtallography as soon as I can arrange an FTP distribution point. It has been suggested to me that it might be placed on MacArchive at the University of Michigan or SUMEX (Stanford's FTP site), but I don't know yet how to access these. If anyone knows, or knows of another site, please let me know.
