Program: EMorient

This program can be used to generate a direct space or reciprocal space stereographic projection of two crystal structure (identical or different) for a given orientation relation. The program takes two crystal structures as input, and then asks for the parallel plane normals (entered as six integers) and the parallel lattice directions (also six integers). Then the use is asked for a direct space or reciprocal space projection, as well as for the central zone axis in crystal A. The results is a PostScript file that shows the overlap stereographic projection with both sets of points.
