A program has been developed to help design a geometric representation of the atomic structure of interfaces between two crystalline structures. The C‐language program run on a graphics‐oriented computer has proved to be a simple precise tool to use. It provides a clear picture of the atomic positions at the interface and, simultaneously, a stereographic projection and diffraction pattern for each crystal and bicrystal. Examples of multiple twinning in the sphalerite structure and of various metal–ceramic interfaces are presented.
