Professor of Computational Design Ramesh Krishnamurti recently published a journal article in the latest edition of Computer-Aided Design. Co-authored with Rudi Stouffs, “A uniform characterization of augmented shapes” reviews different shape-attribute propositions from the shape grammar literature and characterizes them uniformly. This uniform characterization of augmented shapes is intended to assist in formalizing new shape-attribute propositions that may have been visually conceived.

Abstract
Shapes are considered as finite arrangements of spatial elements from among points, line and plane segments, circles and ellipses, (circular) arcs, quadratic Bezier curves, of limited but non-zero measure, in 2D and 3D. Augmented shapes are defined as shapes augmented with attributes, e.g., labels, weights, colors, enumerative values, and (parametric) descriptions. Different attribute types specify different behaviors under operations of sum, product and difference and a part relationship. We review different shape–attribute propositions from the shape grammar literature and characterize them uniformly. This uniform characterization of augmented shapes is intended to assist in formalizing new shape–attribute propositions that may have been visually conceived.
