I highly recommend to use Microsoft Internet Explorer for Java applets! In Netscape the user interface often does not look the way it is supposed to and sometimes sliders and other components show a very irradic behaviour. Also sometimes applets don't start at all or hang up and so on.... |
The diffraction patterns and stereograms for non-icosahedral quasicrystal lattices along general directions are not necessarily symmetrical. This is due to the usage of a simple loop to generate the indices. The implementation of search routines for all the equivalent reflections/poles might be too time consuming for an applet. |
