Shape grammars and shape rules
Journal of Computer Science and Technology, 1987How to generate various graphics and how to produce patterns automatically according to the ideas, requirements and rules of the people (experts), are quite important problems in the computer aided design (CAD) and design automation (DA). This paper presents an approach, using shape grammars, on the basis of shape rules to design pictures, which is a ...

Increasing the Scope of Implemented Shape Grammars: A Shape Grammar Interpreter for Curved Shapes
Volume 3b: 15th International Conference on Design Theory and Methodology, 2003The complexity of shape grammars being produced continues to surpass the technology behind implementing them. One step towards implementing more useful shape grammars is the creation of a subshape matching technique for shapes composed of curved lines that lie in a plane.

Shape grammars are graphical production systems that provide a formal mechanism for generating compositions based on shapes and their spatial relationships by specifying methods to replace parts of shapes with others.

Introduction to shape grammars
ACM SIGGRAPH 2008 classes, 2008The theory of shape grammars defines a formalism to address the ambiguity that quantitative and symbolic computations mostly help us rule out in creative processes. The theory was first launched by Stiny and Gips in 1972 and has evolved into a groundbreaking pragmatist philosophy of shape and design since.The course, composed of a 2 hour lecture and an

Computation-friendly shape grammars
2009NP-hardness of parametric subshape recognition for an arbitrary number of open terms is proven. Guided by this understanding of the complexity of subshape recognition, a framework for computation-friendly parametric shape grammar interpreters is proposed, which is further detailed by a sub-framework over parametric two-dimensional rectangular shapes ...

Introduction to shape and shape grammars
Environment and Planning B: Planning and Design, 1980The definitions pertaining to the shape grammar formalism are developed in detail.In this paper, we take a whirlwind tour through the shape grammar formalism, and the definitions and ideas on which it is based. The formal machinery for the algorithmic definition of languages of two- and three-dimensional spatial designs is thus established.

Environment and Planning B: Planning and Design, 1999
The issue of decidability in relation to shape grammars is considered here. Decidability concerns, first, the identification of different types of grammars and, second, the answerability or solvability of questions about these types of grammars. In this paper, the first of these two topics is examined.

Shape grammars: five questions
Environment and Planning B: Planning and Design, 1999In the paper “Shape grammars: six types”, the issue of decidability in relation to shape grammars was introduced. Decidability concerns, first, the identification of different types of grammars, and, second, the answerability or solvability of questions about these types of grammars. The first of these two topics was explored in “Six types”.

Inca reconstruction using shape grammar
SIGGRAPH '09: Posters, 2009Muller et al. introduced CGA shape, a shape grammar for procedural modeling of architecture [Muller et al. 2006b], which they applied to Mayan archaeological site in Xkipche [Muller et al. 2006a]. Inspired by this application of shape grammars to archaeology, we built a simple reconstruction application that uses a shape grammar to build 3D Inca sites ...
