"bravais" illustrates, in two dimensions, the relationships between a crystal structure and its associated reciprocal lattice. Arbitrary two-dimensional structures with one or two atoms per cell can be constructed and the corresponding reciprocal lattice displayed. "bravais" also simulates the x-ray diffraction for these structures, illustrating the influence of atomic form factor and structure factor on the x-ray pattern. The sizes and total electronic charge of the two atoms can be specified as well as the atomic positions. Connections are made among sets of lattice planes, their Miller indices, and points in the reciprocal lattice.
"bravais" was programmed by Dan Vernon and Joerg Draeger, influenced in part by a problem developed by Judy Franz.
