SHAPE GRAMMAR           The general algebraic framework defined in Stiny 1975 1980 1991 1992 allows shapes and their arrangements to       be added, and taken apart with the aid of sum, product, difference, and the embedding relation, and to be moved or       transformed with the Euclidean transformations. Within this spatial calculus the medium of shape rules is       employed in the production and interpretation of spatial compositions.      4.2.1. What is a shape rule ?           4.2.2. What is a derivation ?      4.2 3.  What is a grammar ?      4.2 4.  What is a shape rule schema ?
