summary We examine an open source 3d suite of tools called blender, as a tool for architectural design. The unique features of blender are examined in terms of ease of use and integrated nature since blender incorporates a simulation engine and a game engine that can be used creatively in the design process. The unique data structure of Blender is examined with the features and work flow that this structure brings in the design process. Also a simple comparison is made between Blender and 3ds max in terms of features and workflow as visualization tools together with an assessment of a two year seminar that took place in the Department of Architecture, in Volos Greece.

summary This paper aims to address innovative approaches in the pedagogical aspects of architecture by describing the work of AA Summer DLAB and Athens | Istanbul (AI) Visiting Schools of the Architectural Association (AA) School of Architecture in London. The presented work is part of a research which enables a more seamless transition from design to fabrication and from academia to profession. The paper formulates the pedagogical and methodological approach towards the integration of generative design thinking, large-scale prototyping, kinetic/interactive design, and participatory design. As such, a discussion on the methods of overcoming the fragmented nature of architectural education via the elaboration of the methodology, computational setup, fabrication strategies, and interaction / kinetic modes of the selected programmes is aspired.

summary The paper addresses a specific method for the production of custom-made, differentiated moulds for the realization of a complex, doubly-curved wall element during an international three-week architectural programme, Architectural Association (AA) Summer DLAB. The research objectives focus on linking geometry, structure, and robotic fabrication within the material agency of concrete. Computational workflow comprises the integration of structural analysis tools and real-time form-finding methods in order to inform global geometry and structural performance simultaneously. The ability to exchange information between various simulation, modelling, analysis, and fabrication software in a seamless fashion is one of the key areas where the creation of complex form meets with the simplicity of exchanging information throughout various platforms. The paper links the notions of complexity and simplicity throughout the design and fabrication processes. The aim to create a complex geometrical configuration within the simplicity of a single material system, concrete, presents itself as an opportunity for further discussion and development.

summary This paper focuses on the realization of three-dimensionally interwoven concrete structures and their design process. The output is part of an ongoing research in developing an innovative strategy for the use of robotics in construction. The robotic fabrication techniques described in this paper are coupled with the computational methods dealing with geometry rationalization and material constraints among others. By revisiting the traditional bar bending techniques, this research aims to develop a novel approach by the reduction of mechanical parts for retaining control over the desired geometrical output. This is achieved by devising a robotic tool-path, developed in KUKA|prc with Python scripting, where fundamental material properties, including tolerances and spring-back values, are integrated in the bending motion methods via a series of mathematical calculations in accord with physical tests. This research serves to demonstrate that robotic integration while efficient in manufacturing it also retains valid alignment with the architectural design sensibility.

summary The paper aims to address methods of realizing computationally generated self-organizing systems on a one-to-one scale with the employment of a singular material system. The case study described in this paper is the outcome of an investigation which has explored earth scaffolding, fabric form-work, and concrete materiality during an international three-week architecture workshop. Real-time generative form-finding methods based on branching and bundling systems in nature have been developed and simulated in an open-source programming environment. The outcome of the simulation stage has been analyzed structurally via Finite Element Analysis (FEA), results of which have served as inputs for the fine-tuning of the simulation. Final three-dimensional geometry has been fabricated by employing fabric, essentially forming the fabric form-work. Fabric form-work is then laid on top of the earth scaffolding, followed by the process of concrete casting. From a pedagogical point of view, the research focuses on the integration of digital design techniques between various design/architecture/analysis platforms combined with basic and advanced techniques of construction within a limited time frame.abstract here by clicking this paragraph.

summary This paper presents the research completed in AA Greece Visiting School 2016 in Thessaloniki. The work integrates computational design and digital fabrication, focusing on aspects of complexity in the making of an architectural interactive prototype. During this research, the use of computation accommodates the design and fabrication of indeterminacy and complexity in different scales and levels . The prototype, Eos, projects on itself the urban characteristics of the city of Thessaloniki. The aim has been to enable a 1-to-1 scale structure to act as a hub of information, capable of communicating with human users through interaction. As the city of Thessaloniki is characterised by specific environmental and urban conditions, the prototype has been set to express such properties.

title Design by Computation - A material driven study
source Kepczynska-Walczak, A, Bialkowski, S (eds.), Computing for a better tomorrow - Proceedings of the 36th eCAADe Conference - Volume 2, Lodz University of Technology, Lodz, Poland, 19-21 September 2018, pp. 279-284
summary The paper aims to address methods of creating a system for design through material studies that are employed as feedback on a computational digital model. The case study described in this paper is the output of an exploration that has investigated physical transformation, interaction and wood materiality over the period of two weeks of the international architecture programme AA Athens Visiting School in Greece. Real-time performative form-responsive methods based on bending and stretching have been developed and simulated in an open-source programming environment. The output of the simulation has been informed by the results of material tests that took place in parallel and have served as inputs for the fine-tuning of the simulation. Final conclusions were made possible from these explorations that enabled the fabrication of a prototype using wood veneer at one-to-one scale. From a pedagogical aspect, the research main focus is to improve the quality of architectural education by learning through making. This is made possible using advanced computational techniques and coupling them with material studies towards an integrated system for architectural prototypes within a limited time frame.

title The teleplastic abuse of ornamentation
source First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 383-392
summary Is it possible that psychoanalysis, a discipline that allegedly deals with abstract or invisible entities, and entomology, a discipline that predominantly taxonomizes insects by type, can offer us an insight into the nature of digital design processes and emergent material phenomena? One of Roger Caillois’ most controversial psychoanalytic theories, “teleplasty,” shows that psychoanalysis and entomology can indeed suggest an alternative perspective of how bodily or other material substances are initially fabricated by insects and how they can further transform. In several of his case studies, Caillois claims alliances between material and psychical structures in his psycho-material teleplastic theorem and eventually questions spatial distinctions: distinctions between geometry and material, purpose and function, cause and effect, between the imaginary and the real. Can digital media help us redefine the static relationship between a window and a wall as an interaction of chemical substances rather than a process of assembling joints and components? Can we perceive material, not as an application to predetermined geometries, but as an inherent condition, a subatomic organization of matter that precedes geometry? The aim of this paper is to problematize such distinctions as a discussion emerging through the prolific use of digital design processes.

title Development of a computerized handbook of architectural plans
source Delft University of Technology
summary The dissertation investigates an approach to the development of visual / spatial computer representations for architectural purposes through the development of the computerized handbook of architectural plans (chap), a knowledge-based computer system capable of recognizing the metric properties of architectural plans. This investigation can be summarized as an introduction of computer vision to the computerization of architectural representations: chap represents an attempt to automate recognition of the most essential among conventional architectural drawings, floor plans. The system accepts as input digitized images of architectural plans and recognizes their spatial primitives (locations) and their spatial articulation on a variety of abstraction levels. The final output of chap is a description of the plan in terms of the grouping formations detected in its spatial articulation. The overall structure of the description is based on an analysis of its conformity to the formal rules of its “stylistic” context (which in the initial version of chap is classical architecture). Chapter 1 suggests that the poor performance of computerized architectural drawing and design systems is among others evidence of the necessity to computerize visual / spatial architectural representations. A recognition system such as chap offers comprehensive means for the investigation of a methodology for the development and use of such representations. Chapter 2 describes a fundamental task of chap: recognition of the position and shape of locations, the atomic parts of the description of an architectural plan in chap. This operation represents the final and most significant part of the first stage in processing an image input in machine environment. Chapter 3 moves to the next significant problem, recognition of the spatial arrangement of locations in an architectural plan, that is, recognition of grouping relationships that determine the subdivision of a plan into parts. In the absence of systematic and exhaustive typologic studies of classical architecture that would allow us to define a repertory of the location group types possible in classical architectural plans, Chapter 3 follows a bottom-up approach based on grouping relationships derived from elementary architectural knowledge and formalized with assistance from Gestalt theory and its antecedents. The grouping process described in Chapter 3 corresponds both in purpose and in structure to the derivation of a description of an image in computer vision [Marr 1982]. Chapter 4 investigates the well-formedness of the description of a classical architectural plan in an analytical manner: each relevant level (or sublevel) of the classical canon according to Tzonis & Lefaivre [1986] is transformed into a single group of criteria of well-formedness which is investigated independently. The hierarchical structure of the classical canon determines the coordination of these criteria into a sequence of cognitive filters which progressively analyses the correspondence of the descriptions derived as in Chapter 3 to the constraints of the canon. The methodology and techniques presented in the dissertation are primarily considered with respect to chap, a specific recognition system. The resulting specification of chap gives a measure of the use of such a system within the context of a computerized collection of architectural precedents and also presents several extensions to other areas of architecture. Although these extensions are not considered as verifiable claims, Chapter 5 describes some of their implications, including on the role of architectural drawing in computerized design systems, on architectural typologies, and on the nature and structure of generative systems in architecture.

title Agents' movement_towards the reformation of public space - Step 1: select | implement | observe crowd rules
source Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 1, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 53-62

summary In order to enable designers to envision the behaviour of pedestrians with reference to specific environments, computational models of crowds and their movement become indispensable tools of evaluation as well as tools of creativity. In this paper, the model under development constitutes a generic model which incorporates ideas about agent-based systems. The simulation program comprises a support system for the designer to place virtual users in a context that bears analogous environmental traits of the area under study. The design problem which is addressed by the implementation deals with public squares for which the programmatic demands involve a broad spectrum of users of diverse idiosyncrasies. Our study attempts to elucidate how the variation in preferences of pedestrian movement which depend on various personal, situational and environmental factors, may influence the current use of a selected public space and underpin qualitative alterations compared to its initial design. The intent of the methodology is not to create a predictive tool of naturalistic human movement but to explore how spatial configuration can be assessed and developed through a simulation model of pedestrian behaviour.

title Parametric Models and Algorithmic Thinking in Architectural Education

summary Part of our research and teaching agenda at the School of Architecture of the Technical University of Crete focuses on algorithmic design with parametric models, its methodological characteristics and the study of applied and theoretical work that defined this architectural design thinking. Our work challenges architectural design processes, through the systematic study of parametric models. This paper presents three projects from the undergraduate elective course "Special Topics in Architectural Design", which took place during the spring semester of 2017, that investigated parametric models for a given architectural problem, inspired, to some extent, by precedents in 20th century architecture where students traced algorithmic design thinking. Although students understood well the concept and function of parametric models and in many cases applied them successfully for their design objectives, several of them did not fully assimilate some critical aspects of computation. This allowed us to determine areas of improvement and points of complete reevaluation in our educational strategy approach.

title Algorithmic Thinking in Design and Construction - Working with parametric models
source Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 19-28
summary This paper examines the parametric model in algorithmic design processes, using the outcome of an educational digital design and fabrication course as a case study. In its long history, algorithmic design as a form-finding method, allowed designers to manage complex non-standard associative geometries, suggesting a shift from the digital representation of form, to its systematic representation into a parametric model through code. Rather than a style or a tool, the parametric model is best defined in mathematical terms; in practice it incorporates the organizational logic of the form and the topological associations of its parts, so that a change in its constitutive parameters will invoke a concerted update of the entire model, and, iteratively, formal and structural variations. In a series of design experiments that took place at the School of Architecture of the Technical University of Crete in the spring of 2015, we used parametric models represented into visual code, from the initial conceptual stage to fabrication. From the experience and outcome of this course, we deduced that, compared to other digital formation methods, parametric models allow the designer to constantly interact with the model through the code, producing discreet variations without losing control of the design intentions, by “searching” into a wide range (albeit finite) of virtual results. This suggested a shift in culturally embedded patterns of modernist design thinking.

summary We introduce Human-Building Collaboration (HBC), a pedagogical framework for the design of next-generation smart buildings in architecture. Using the framework's philosophy, model, and tools we show designers how to enhance smart building performance by increasing and diversifying the ways humans have to share their intelligence with that of the building. We apply this framework through design exercises and present the result of two projects: (1) a tangible wall interface for lighting co-optimization and (2) a shape display facade interface for rainwater purification and reuse. Preliminary findings demonstrate that the framework helped designers proposing new means for humans to collaborate with smart buildings.

summary Contemporary voxel based CAD software uses a predetermined voxel space as a property placeholder for establishing relationships between boundaries and properties (weights). The Marching Shape algorithm, developed as an extension of the Ice Ray Shape Grammar, demonstrate how similar relationships between weights and boundaries can be developed without the fixed structure of Voxels. An extended Ice-Ray is presented that includes rules and schemas for polygons of more than 5 vertices, rules for the manipulation of weights as well as rules that establish relationships between them.
