CAREWARE

I highly recommend to use Microsoft Internet Explorer for Java applets!

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.
