Quasicrystal Reflection Generator
    JCrystalSoft, 2011

Version 1.2.0 (04/21/2011)  

QuaRef  is a stand-alone software for Windows. It creates lists of reflections for dihedral (octagonal, decagonal, dodecagonal) and icosahedral quasicrystals. It displays the 0th. layer as a static image and the the whole set of reflections in an interactive 3D viewer. The reflections can be rotated by dragging the mouse over the display area. For the simulation the user can choose between lattice matrices as used by Dr. Akiji Yamamoto or Prof. Walter Steurer.

QuaRef observes the extinction rules for the chosen space groups. The encoded extinction rules are based on the paper by Rabson, Mermin, Rokshar, Wright, 1991.
