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

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

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? In addition to providing answers to the above questions this paper presents: 1. Concepts behind L-systems 2. The need to transform L-Systems so they can have creative architectural application possibilities 3. Examples on the architectural use of L-Systems 4. Conclusions

title THE EMERGING DIGITAL STYLE: Attention shift in architectural style recognition

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?

summary The purpose of this study is to analyze William Hajjar’s singlefamily houses in State College, PA, and compare them with the European modernist work of Walter Gropius and Marcel Breuer in the United States. This analysis is performed using shape grammars as a computational design methodology. Hajjar was a member of the architecture faculty at the Pennsylvania State University, a practitioner in State College, and an influential figure in the history of architecture in the area. Shape grammars are used specifically to verify and describe the influences of Bauhaus/European modernism on Hajjar’s domestic architecture. The focus is on establishing Hajjar’s single-family architectural language and comparing it to the architectural language of Gropius (Gropius-Breuer partnership) as the founder of the Bauhaus architecture and a prominent practitioner in introducing European modernism to American architecture students in the mid-twentieth century like Hajjar.

title Architectural Dramaturgy: A total and endless theatre with multimodal artificial intelligence
source Kontovourkis, O, Phocas, MC and Wurzer, G (eds.), Data-Driven Intelligence - Proceedings of the 42nd Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2024), Nicosia, 11-13 September 2024, Volume 1, pp. 559–564
doi https://doi.org/10.52842/conf.ecaade.2024.1.559
summary Close to a century ago, Walter Gropius proposed the highly influential but unrealised project ‘Total Theatre’ (1927). The project captured Gropius’ adapted formulation of ‘Gesamtkunstwerk’(‘total work of art’) as ‘Total Design’ within the Bauhaus, and more specifically, in relation to ‘The Theatre of the Bauhaus’ (1924). The ‘Total Theatre’ was Gropius’ attempt to dynamically reconfigure the previously static relationship between actors and audience into one that is participatory and filmic in spatial layout. Around the same time in history, shortly after designing the set for Eugene O’Neill’s ‘The Emperor Jones’ in 1924, Frederick Kiesler began to conceptualise his ‘Endless Theatre’ (1926). In the former, Kiesler created a constructivist stage space with moving walls/floors/ceilings animating in-sync with the play’s narrative and producing cinematographic effects similar to those found in films. For both Gropius and Kiesler, the theatre is a fertile ground for incorporating the latest technologies to prototype a ‘totally’ multimodal and ‘endlessly’ generative form of architecture. Against the backdrop of such past intellectual efforts in architecture, and that of today’s rapidly foregrounding of Large Language Models (LLMs) and Large Multimodal Models (LMMs) in artificial intelligence (AI) within the architecture discipline, the paper posits that it is timely to revisit this conceptual cross-fertilisation of theatre and architecture – architectural dramaturgy. In doing so, the research aims to extend Gropius’s and Kiesler’s concept of the ‘total’ and the ‘endless’ respectively through the lens of the ‘computational’. The first experiment uses different datasets from existing established theatre creators to train and prompt-engineer relevant AI models, namely a text-to-text model for playwright Arthur Miller, a text-to-image model for director Ivo van Hove, and a text-to-audio model for composer Stephen Sondheim. In improving the coherence of the results, the second experiment replaces unimodality with multimodality leveraging a single source of video data (the poignant “To be or not to be” soliloquy from Shakespeare’s Hamlet) to formulate a human-in-the-loop interpretative framework by utilising a combination of text-image-to-image model and text-image-to-video model, and further postprocessed with image inpainting model and image-to-3D model. With the deliberate bracketing of site, programmes and other specificities typical of an architecture project, the research demonstrates how concepts borrowed from theatre when layered with multimodal AI could extend the discipline’s longstanding conception of a total and endless architecture.

title Developing a New Approach of Computer Use ‘KISS Modeling’ for Design-Ideas Alternatives of Form Massing: A framework for three-Dimensional Shape Recognition in Initial Design Phases
source Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 745-756
summary This research aims at developing a new approach called ‘KISS Modeling’. KISS is generally a rule of ‘Keep It Simple, Stupid’ that will be applied in modeling process investigated and presented by the research. The new approach is implemented in a computer program ‘KISS Modeling’ that generates three dimensional forms based on simplifying the concept of shape recognition in design. The research, however, does not employ totally concepts of shape recognition or shape understanding in Artificial Intelligence and psychology. The research, in summary, investigates and describes: 1) a new approach of computer use contributing to generating design-ideas alternatives of form massing in initial design phases, within a simple way that any designer can understand at single glance, 2) implementation of shape recognition for generative three dimensional forms, 3) function to generate different outputs from different recognition, and 4) case studies introduced through applications and functions of the three dimensional modeling system presented by the research. The research concluded that the introduced processes help the user improve the management of conceptual designing through facilitating a discourse of his/her modeling of design-ideas massing.
