title LOS "SPIROSPACES"
source Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 179-187.
summary This paper deals with “Spirospaces”. These are a conversion to the third dimension of the two dimensional geometric entities called “Spirolaterals”.

Abelson, Harold, diSessa and Andera (1968) gave the first rules concerning Spirolaterals. To obtain a Spirolateral from a set of straight lines, the first of them must be one unit long and the following must be incremented one unit at each step, at the same time that they turn in a constant direction. Odds (1973) establish the variation of the rotation direction, either to the left or the right. However, he did not give a mathematical relation able to calculate open Spirolaterals. Krawczyk (2001) developed a computer program that generates Spirolaterals following the method suggested by Abelson. These are Spirolaterals obtained by enumeration without a predictive mathematical formula. Krawczyc went farther proposing Spirolaterals based in curved lines. He pointed out that there are a variety of spirolateral forms that have architectural potentiality. Following this, the architectural potentiality of Spirolaterals is the basis of this paper.

To take advantage of that potentiality a computer program was implemented to generate spatial configurations based in Spirolaterals. When a third dimension is given to the Spirolaterals they become Spirospaces. These new entities need spatial and design parameters to be useful for architectural purposes. Barrionuevo and Borsetti (2001) gave results about that work establishing the concept of Spirospaces.

The aim of this paper is to describe a work directed to improve rules and procedures concerning Spirospaces. It is expected that these procedures governed by the proposed rules can be employed as tools during the early steps in the architectural design process.

In this work some aspects concerning Spirospaces are considered. First, Spirolaterals are presented as the predecessors of Spirospaces. Second, Spirospaces are defined, together with their structural parameters. Architectural modeling is studied at the light of two special elements of the Spirospaces: Interstitial spaces and Object spaces. Next, a computer program is presented as the appropriate tool to model configurations having architectural potentiality. Finally, the results obtained running the computer program are analyzed to determine their possible use as architectural forms. Several graphic illustrations are presented showing steps going from the exploration of spatial alternatives to the selection of a specific configuration to be developed.

It is expected that the described computer program could be employed as a design aid tool. As the operation of the program generates a variety of spaces able to dwell architectural objects, it eases the search of configurations suitable to specific functions. The results obtained have the possibility of being exported to computer graphic applications able to add materials, lights and cameras.

title Is Language All We Need? A Query Into Architectural Semantics Using a Multimodal Generative Workflow
source Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 353-362
doi https://doi.org/10.52842/conf.caadria.2022.1.353
summary This project examines how interconnected artificial intelligence (AI)-assisted workflows can address the limitations of current language-based models and streamline machine-vision related tasks for architectural design. A precise relationship between text and visual feature representation is problematic and can lead to "ambiguity‚ in the interpretation of the morphological/tectonic complexity of a building. Textual representation of a design concept only addresses spatial complexity in a reductionist way, since the outcome of the design process is co-dependent on multiple interrelated systems, according to systems theory (Alexander 1968). We propose herewith a process of feature disentanglement (using low level features, i.e., composition) within an interconnected generative adversarial networks (GANs) workflow. The insertion of natural language models within the proposed workflow can help mitigate the semantic distance between different domains and guide the encoding of semantic information throughout a domain transfer process.

title Parametric and generative methods with building information modelling: Connecting BIM with explorative design modelling
source Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 537–546
doi https://doi.org/10.52842/conf.caadria.2012.537
summary Parametric and generative modelling methods are ways in which computer models are made more flexible, and of formalising domain-specific knowledge. At present, no open standard exists for the interchange of parametric and generative information. The Industry Foundation Classes (IFC) which are an open standard for interoperability in building information models is presented as the base for an open standard in parametric modelling. The advantage of allowing parametric and generative representations are that the early design process can allow for more iteration and changes can be implemented quicker than with traditional models. This paper begins with a formal definition of what constitutes to be parametric and generative modelling methods and then proceeds to describe an open standard in which the interchange of components could be implemented. As an illustrative example of generative design, Frazer’s ‘Reptiles’ project from 1968 is reinterpreted.

title Generative and Evolutionary Techniques for Building Envelope Design
source International Conference on Generative Art
summary The authors have been involved in the use of generative techniques for building envelope design since 1968 and the use of genetic algorithms since 1990. Recent work has focused on incorporating optimisation functions into form generating processes in order for new forms responding to varied design environments to be created and determined. This paper will summarise the authors’ previous work in this field and explain the theory behind this approach, and illustrate recent developments. While the initial implementation of a new building envelope design system is reported in more details in a related paper at this conference, this paper outlines its main features and points out the direction at which it is to be fully developed and further improved.

title Use of Generative Systems to Create Semi-Public Spaces in Contemporary Neighborhood Texture

summary Cul-de-sacs are examined together with the urban reading in Siverek. Studying cul-de-sacs is instrumental to understand the morphology of Islamic cities. Cul-de-sacs provide a buffer zone between main roads and houses. For this reason, both the privacy phenomenon, which is one of the important issues for Islam, and the safe space need of the residents are important spatial elements. Until 1968, the city of Siverek developed organically within a compact texture of narrow and curvilinear streets, open courtyards, and a adjacent high-walled residences. In this texture, many semi-private cul-de-sacs have an organic form, which is one of the critical spatial elements of the city. Residential walls or courtyard walls form the natural line of traditional streets. In this study, typological analyses of cul-de-sacs were made, and form grammar, a productive method used to analyze architectural language, is included. It aims to examine the relationship between residential settlement and street using the data set created with shape grammars and to make urban propositions for neighbourhood structures in the context of a cul-de-sac using L-systems in the next step. Some parameters have been determined in forming cul-de-sacs that form the urban texture. These parameters were transferred to the model using digital tools. A method thought to be used in urban production has been put forward. The most important reference of this method is dead-end streets.

title Calculating Visual Complexity In Peter Eisenman’s Architecture
source Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 75-84
doi https://doi.org/10.52842/conf.caadria.2009.075
summary This paper describes the results of the first computational investigation of characteristic visual complexity in the architecture of Peter Eisenman. The research uses a variation of the “box-counting” approach to determining a quantitative value of the formal complexity present in five of Eisenman’s early domestic works (Houses I, II, III, IV and VI all of which were completed between 1968 and 1976). The boxcounting approach produces an approximate fractal dimension calculation for the visual complexity of an architectural elevation. This method has previously been used to analyse a range of historic and modern buildings including the works of Frank Lloyd Wright, Eileen Gray, Le Corbusier and Kazuyo Sejima. Peter Eisenman’s early house designs–important precursors to his later Deconstructivist works–are widely regarded as possessing a high degree of formal consistency and a reasonably high level of visual complexity. Through this analysis it is possible to quantify both the visual complexity and the degree of consistency present in this work for the first time.

summary In 1968 Aristid Lindenmayer proposed a series of mathematical constructs as a foundation for an axiomatic theory of form development. Since that time, Lindenmayer Systems or L-systems have evolved and found many practical applications in the computer visualization area. Generation of fractal imagery, realistic modeling and high quality visualization of organic forms and even music generation are now possible with the assistance of L-systems. But, is it possible to use L-systems in architectural design? Why would anyone use L-systems in architectural design? How would one use them? What could one expect from their use?

title THE EMERGING DIGITAL STYLE: Attention shift in architectural style recognition
source CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 633-635

summary “Style” has long been an important index to observe the design thinking of designers in architecture. Gombrich (1968) defined style as a particular selection from the alternatives when doing things; Ackerman (1963) considered that a distiguishable ensemble of certain characteristics we call a style; Schapiro (1961) pointed out that style is constant forms, and sometimes the constant elements, qualities and expression; Kirsch (1998), Cha and Gero (1999) thought of style as a form element and shape pattern. As Simon and others referred to, style emerged from the process of problem solving, Chan (1994, 2001) ever devised a serious of experiments to set up the operational definitions of style, further five factors that relate to generating styles. Owing to that the greater part of sketches and drawings in the design process couldn’t be replaced by computer-aided design systems (Eisentraut, 1997), designers must shift between different problem-solving methods while facing different design problems. The purpose in this research is to discuss the influences of computer usage on style generation and style recognition: The employment of certain procedural factors that occurred in the design processes that using conventional media is different from the ones that using computer media? Do personal styles emerge while designers shifting between different media in the design processes? Does any unusual phenomenon emerge while accustomed CAD-systems designers recognizing a style?
