    Random-context grammars are progressively extended to three dimensions. Random-context structure grammars that generate three-dimensional digital structures are introduced. The characterization of random-context array grammars and random-context structure grammars by two-dimensional random- context array automata and three-dimensional random-context structure automata respectively is investigated. A possible practical application of random-context structure grammars and automata in the modeling of chemical molecules is speculated on.
