better snowflakes

The artificial snowflakesd-8498 of my earlier post have several defects in comparison to real snowflakes. First, the arms split up into five arms. But for real snowflakes they mostly split up only into three arms. Second, the edges should be straight and have the directions of the basic hexagon. Failing this, I got snowflakes that seem to be melting. I can easily correct this errors. The results are more realistic but maybe too compact. See the examples shown here. To get very realistic snowflake shapes one could try to use Lindenmayer systems instead of cellular automata. Lindenmayer systems are essentially recursive methods for defining self-similar images like fractals or growing structures. You can find an excellent introduction in the book “The algorithmic beauty of plants” by Przemyslaw Prusinkiewicz and Aristid Lindenmayer.
