Crystal structures with CAs

A recent paper in the journal Acta Crystallographica A explores modeling crystal growth with 3-D CAs.

Crystal structures and cellular automata

Krivovichev, S. V.

Abstract: Cellular automata are used as dynamic topological models of crystal structures based upon frameworks consisting of fundamental building blocks. Structure is considered as an automaton that works in accord with a prescribed program. Cellular automata models are constructed for metal sulfide frameworks in minerals and compounds of the pentlandite-djertisherite-bartonite series, for zeolite ACO and compounds with pharmacosiderite structure, leucophosphite, phosphovanadylite etc.



Comment - It would be nice to see this sort of work extended to more interesting crystal forms than the fairly simple ones considered in this paper. What rules leave behind interesting and intricate patterns like those seen in many minerals?

kazume nishidate has published an article on the use of ca's to model etching processes on a metal. i think it may have appeared in the J. Physical
Society of Japan but i'm sure any one interested in this can google it.
