Shapes: Seeing and doing with shape grammars

This paper describes the visual interface of a configurable and extensible system to support generic work with shape grammars. Shape grammars allow the implementation of computational mechanisms to analyze and synthesize designs of visual languages and have been used to represent the knowledge behind the creative work of architects, designers and artists. This kind of grammars is inherently visual. The system described, a kind of universal machine for shape grammars, allows users to build their own shape grammars and experiment with them. It has been the focus of our past work, it mixes technological and artistic aspects and it has a specific computational architecture which includes a symbolic and a visual interface. The latter one is the subject of this paper.info:eu-repo/semantics/acceptedVersio

What’s in a shape: An algorithm for finding shapes in shapes

This paper describes a simple two stage algorithm for finding emergent sub-shapes in shapes, in the context of shape grammar systems. Matching the shape in the left side of a rule of a shape grammar with parts of a shape in a design in process to decide if the rule is applicable, is its main purpose. Shape grammars have been used to represent the knowledge behind the creative work of architects, designers and artists and allow the implementation of computational mechanisms to analyze and synthesize designs of visual languages, with obvious applications to design, including for marketing. Their computational mechanisms can include the detection of emergent sub-shapes. The algorithm we propose performs this task and is a core component of a system, described in our past work, that allows users to build their own shape grammars and use them.info:eu-repo/semantics/acceptedVersio
