ResumoComputer programs were developed to provide for computer plotting of standard stereographic Kikuchi projections of any desired orientation and projection sphere radius for fcc (Al), bcc (Fe), diamond cubic (Si), and hcp (α-Ti) crystals. The programs also provide for automatic identification of Kikuchi poles as well as identification of individual Kikuchi lines. Indexing of observed patterns becomes a matter of comparison between the experimental patterns and the projections. Coates projections for scanning electron microscopy and transmission Kossel or pseudo-Kossel projections for x-ray diffraction studies can also be generated simply by changing the input wavelengths. The matrix algebra employed in producing the projections is presented, and the details of the computer programs are described.
