This program was developed by James Cheney (C++, Macintosh platform),
and can be used both as an educational tool and as a real research program.
All computations follow the proper underlying physics.
The program permits the user to define an arbitrary unit cell, display the unit cell
or an array of cells, display the Debye-Scherrer pattern, a standard powder pattern,
the stereographic projections of real space and reciprocal space, and transmission and reflection
Laue patterns. All windows can be linked together so that a rotation in one of the
windows will automatically update all others.
The module is available at no cost for educational purposes or non-profit individual use.

then follow the instructions in the README file.
The Windows 95 version is not yet available. I am looking for a bright programmer
to transfer the C++ code to the Windows platform. At this point I do not have
anybody working with me, so the PC version will be unavailable until further notice.
The development of this program was only possible with financial help from the National Science Foundation (DMR-9501017, Bruce MacDonald program monitor). We welcome any kind of feedback about this program; in particular, we are looking for answers to the following questions:
