title Touch, See, Make: Employing Active Touch in Computational Making
source ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 128-137
summary In architectural education and practice, we don’t come in physical contact with what we make until the later stages of the design process. This vision-oriented approach to design is something deeply rooted in architectural practice: from Alberti’s window to the screens of our computers, design has traditionally been more of a visual and less of a hands-on process. The vision of the presented study is that if we want to understand the way we make in order to improve tools for computational design and making, we need to understand how our ability to make things is enhanced by both our visual and tactile mechanisms. Bringing the notion of active touch from psychology into the design studio, I design and execute a series of experiments investigating how seeing, touching, or seeing and touching exhibit different sensory competencies, and how these competencies are expressed through the process of making. The subjects of the experiment are asked to tactilely, visually, or tactilely and visually observe a three-dimensional object, create descriptions of its composition, and to remake it based on their experience of it using plastic materials. After the execution of the experiment, I analyze twenty-one reproductions of the original object; I point to ways in which touch can detect scale and proportions more accurately than vision, while vision can detect spatial components more efficiently than touch; I then propose ways in which this series of experiments can lead to the creation of new design and making tools.

title Modelling Alberti’s Column System: Generative Modelling and Digital Fabrication of Classical Architectural Elements
source Achten, Henri; Pavlicek, Jiri; Hulin, Jaroslav; Matejovska, Dana (eds.), Digital Physicality - Proceedings of the 30th eCAADe Conference - Volume 2 / ISBN 978-9-4912070-3-7, Czech Technical University in Prague, Faculty of Architecture (Czech Republic) 12-14 September 2012, pp. 469-477
summary The research presented further is part of the Digital Alberti research project, which aims to assess the infl uence of Leon Batista Alberti’s theory on Portuguese architecture, through the use of digital technologies. One of the project tasks implied computational and physical modelling of Alberti’s column system. Development of the computational model implied decoding Alberti’s treatise on architecture De re aedifi catoria into a consistent set of parameters and relationships, and then implementing these into generative parametric computer programs through visual programming language Grasshopper. This computational model is able to automatically generate physical models of classical columns according to Alberti’s canons. These digital models were then materialized through production of physical models, through rapid prototyping and digital fabrication technologies. Special attention is given to the CNC stone milling of a Corinthian capital.

title A computational interpretation of ”De re aedificatoria”: Translating Alberti’s column system into a shape grammar
source RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.788-798
summary Alberti’s ”De re aedificatoria” is considered one of the most influential treatises of architecture. Historic approaches aimed at tracing such an influence on European architecture have relied mainly on documental sources. The extent of such an influence, however, remains elusive. The research described in this paper is part of a larger project aimed at using the computational framework provided by shape grammars to determine the extension of such an influence on the architecture of the Portuguese empire in the counter-reform period. The idea is to translate the treatise into a shape grammar and then determine the transformations required for the grammar to account for the generation of the buildings designed and built in this geographic region. The paper presents a grammar for the Albertian column system, focusing on the Doric order. Subsequent work will be concerned with identifying the transformations of this grammar in the Portuguese context.

title A Shape Grammar to Generate Loggia Rucellai
source Open Systems: Proceedings of the 18th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2013) / Singapore 15-18 May 2013, pp. 791-800
summary This article shows the result of generating a 3d model of Loggia Rucellai in Florence using a shape grammar from Leon Batista Alberti’s treatise De Re Aedificatoria and it is a test bed for further generations of buildings using Alberti’s rules. It shows the accuracy of such grammar to help tracing the degree of influence of Alberti’s treatise in Renaissence Portuguese architecture. Rucellai palace facade ornaments and its interior loggia where used to analyze and compare the Loggia generation accuracy. A Grasshopper script is used for the automation of the rules derivation. An evaluation process is presented and its use aims to better understand the deviations between the treatise and the Loggia grammars.

title From Point Cloud to Shape Grammar to Grammatical Transformations
source Stouffs, Rudi and Sariyildiz, Sevil (eds.), Computation and Performance – Proceedings of the 31st eCAADe Conference – Volume 2, Faculty of Architecture, Delft University of Technology, Delft, The Netherlands, 18-20 September 2013, pp. 655-663
summary This paper describes a generative design approach integrating real building data in the process of developing a shape grammar. The goal is to assess to which extent it is feasible the use of a reverse engineering procedure to acquire actual building data and what kind of impact it may have on the development of a shape grammar.The paper describes the use of Terrestrial Laser Scanning (TLS) techniques to acquire information on the Săo Vicente de Fora church, then the use of such information to develop the corresponding shape grammar, and finally the comparison of this grammar with the grammar of Alberti’s treatise, to determine the grammatical transformations that occurred between the two grammars.

title A Multisensory Computational Model for Human-Machine Making and Learning
source ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 238-247
summary Despite the advancement of digital design and fabrication technologies, design practices still follow Alberti’s hylomorphic model of separating the design phase from the construction phase. This separation hinders creativity and flexibility in reacting to surprises that may arise during the construction phase. These surprises often come as a result of a mismatch between the sophistication allowed by the digital technologies and the designer’s experience using them. These technologies and expertise depend on one human sense, vision, ignoring other senses that could be shaped and used in design and learning. Moreover, pedagogical approaches in the design studio have not yet fully integrated digital technologies as design companions; rather, they have been used primarily as tools for representation and materialization. This research introduces a multisensory computational model for human-machine making and learning. The model is based on a recursive process of embodied, situated, multisensory interaction between the learner, the machines and the thing-in-the-making. This approach depends heavily on computational making, abstracting, and describing the making process. To demonstrate its effectiveness, I present a case study from a course I taught at MIT in which students built full-scale, lightweight structures with embedded electronics. This model creates a loop between design and construction that develops students’ sensory experience and spatial reasoning skills while at the same time enabling them to use digital technologies as design companions. The paper shows that making can be used to teach design while enabling the students to make judgments on their own and to improvise.

title Digital Temples: a shape grammar to generate sacred buildings according to Alberti’s theory
source FUTURE TRADITIONS [1st eCAADe Regional International Workshop Proceedings / ISBN 978-989-8527-03-5], University of Porto, Faculty of Architecture (Portugal), 4-5 April 2013, pp. 63-70
summary The research presented further is part of the Digital Alberti research project, which aims to determine the influence of Alberti’s treatise on Architecture, De re aedificatoria, on the Portuguese Renaissance architecture, through the use of a computational framework. One of the project tasks entailed the translation of the treatise’s textual descriptions concerning the morphological, proportional and algorithmic principles of the sacred buildings into a shape grammar. Subsequently a computational model was developed, in order to proceed to the derivation of examples of the same language. This article discusses the use of analytical shape grammars to undertake an architectural analysis, as well as the fact of the source of this grammar and correspondent architectural language to be a text instead of a set of buildings and designs. It reviews the methodology to implement the shape grammar and describes the several stages of development, following the interpretation of treatise into a consistent set of shape rules, by defining their spatial relations, parameters and conditions. It also reviews the implementation of this knowledge into a generative parametric computer program through visual programming language Grasshopper.

summary This paper presents a research on the use of shape grammars as an analytical tool in the history of architecture. It evolves within a broader project called Digital Alberti, whose goal is to determine the influence of De re aedificatoria treatise on Portuguese Renaissance architecture, making use of a computational framework (Krüger et al., 2011).Previous work was concerned with the development of a shape grammar for generating sacred buildings according to the rules textually described in the treatise. This work describes the transformation of the treatise grammar into another grammar that can also account for the generation of Alberti’s built work.

title Modular Perspective as a Method for Generative Design
source International Conference on Generative Art
summary Apparently there are many methods for perspective but if we categorize them there are just a few. Some criterions of classification relate perspective to the so-called 1-point, 2-point and 3-point methods, others —more formally— to projective geometry, descriptive geometry or vectorial algebra. Of course we cannot forget to mention the early treatises on perspective such as Alberti’s Della Pittura or Piero’s De Prospectiva Pingendi, which escapes any classification. Our aim on this article is not precisely to solve the classification problem rather we propose a new comprehensive method for perspective, capable of 3D representation without using vanishing points.The modular perspective method allows us to work in true three-dimensionality on the perspective plane (PPl). We will explain how to measure directly on the PPl the triad coordinates (x, y, p) of a given point into the visual space, and how to play with the symmetrical planes X and Y (SPl X/Y) in order to generate or recover data. Finally we will explain how to employ modular perspective in generative design formal-process through an example of application.

title The Novel Stones of Venice: The Marching Cube Algorithm as a Strategy for Managing Mass-customisation
source ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 311-318
summary The Marching Cube (MC) algorithm is a simple procedural routine for the surface representation of three- dimensional scalar fields. While much has been written of the algorithm’s efficiencies and adaptive nature within the domain of computer graphics and imaging, little has been explored within the context of architectural geometry and fabrication. This paper posits a novel implementation of the MC algorithm coupled with robotic fabrication (RF) techniques, to realise an open-ended design method that approaches mass-customisation as the unique geometric distortion of a finite set of topologically consistent families of tectonic elements.The disciplinary consequences of this and similar methods that intimately couple algorithmic design techniques with robotic fabrication are discussed. These include the re-affirmation or expansion of the role of the architect as master builder that is enabled by challenging Leon Battista Alberti’s 15th Century division between design concept and building.The method and its disciplinary potentials are illustrated through the description of an installation built by the authors for the Australian Pavilion at the Venice Biennale. Clouds of Venice serves as a case study for a new integrated mode of production, one that increases the quality and number of feedback relations between design, matter and making.
