summary Parametric modelling is gaining in popularity as both a fabrication and design tool, but its application in the architectural design industry has not been widely explored. Parametric modelling has the ability to generate complex forms with intuitively reactive components, allowing designers to express and fabricate structures previously too laborious and geometrically complex to realise. This allows designers to address a project at both the macro and micro levels of resolution in the governing control surface and the individual repetitive component. This two level modelling control, of component and overall surface, can allow designers to explore new types of form generation subject to parametric constraints. Shading screens have been selected as the focus for this paper and are used as a medium to explore form generation within a given set of functional parameters. Screens can have many applications in a building but for the purpose of the following case studies, lighting quality and passive sun control are the main functional requirement. A set of screen components have been designed within certain shading parameters to create a generic component that can automatically adapt to any given climatic conditions. These will then be applied to surfaces of varying degrees of geometric complexity to be analysed in their ability to correctly tessellate and create a unified screening array true to the lighting requirements placed on the generic component.

title Digital Design to Digital Production: Flank Milling with a 7-Axis CNC-Milling Robot and Parametric Design
doi https://doi.org/10.52842/conf.ecaade.2009.323

summary Just recently Flank Milling has opened up new possibilities in detailing large-scale architectural building envelopes. Whereas examples such as the Hungerburgbahn by Zaha Hadid show the application of Flank Milling at the end of the architectural manufacturing process, our research, in contrast, focuses on the implementation of constraints immanent to manufacturing techniques as early architectural design parameters. This process is explored by the help of generative modeling tools, to allow an intuitive design of freeform parametric curves and surfaces while at the same time obeying crucial geometric conditions. In this paper, we will focus on the “digital design to digital production” process on a 7-axis industrial CNC -robot.

summary This paper deals with 3D modeling of complex architectural elements for virtual 3D scene reconstruction based on images or point clouds. It presents a new method at the opposite of classical photogrammetry and lasergrammetry techniques: parametric components are created and then adapted to the measured data. We have conceived and developed a parametric shape generator tool for virtual 3D reconstruction of cultural heritage monuments. We present the geometrical study on the cupola shapes with all their diversity. It is illustrated with the Suleymaniyé Mosque in Turkey. The results are promising. The modeling time is greatly reduced.

summary The materialization of architectural forms uses new processes aided by digital manufacturing techniques (FD). Five FD techniques stand out: sectioning (serial planes), tessellation, folding, contouring, and forming. This article's objective is to characterize the state of the art of these techniques, from 2009 to 2020 in national and international research bases. The Systematic Literature Review is used from three stages and nine protocol phases. The results indicate the techniques, methods, computer simulations, and applicability in more recurrent materials.

title Non-Deterministic Exploration through Parametric Design
source International Journal of Architectural Computing vol. 7 - no. 4, 605-622
summary This paper explores non-deterministic parametric modelling as a design tool. Specifically, it addresses the application of parametric variables to the generation of a conceptual bridge design and the use of repeatable discrete components to the conceptual form. In order to control the generation of the bridge form, a set of design variables based on the concept of a law curve have been developed. These design variables are applied and tested through interactive modelling and variation, driven by manipulating the law curve. Combining this process with the application and control of a repeatable element, known as a Representative Volumetric Element (RVE), allows for the development and exploration of a design solution that could not be achieved through the use of conventional computer modelling. The competition brief for the Australian Institute of Architects (AIA) ‘Dialectical Bridge’ has been used as a case study to demonstrate the use of non-deterministic parametric modelling as a design tool. The results of the experimentation with parametric variables, the law curve and representative volumetric elements (RVE) are presented in the paper.

title TetraScript: Development of an Integrated System Capable of Optimizing Light in a Circumscribed Space
doi https://doi.org/10.52842/conf.ecaade.2009.031
source Computation: The New Realm of Architectural Design [27th eCAADe Conference Proceedings / ISBN 978-0-9541183-8-9] Istanbul (Turkey) 16-19 September 2009, pp. 31-38
summary The purpose of this research is to develop a process capable of optimizing the capture of light in a circumscribed space, using a responsive system of skylights. Research is focused on the design of irregular dome-like pavilion spaces circumscribed by curved surfaces, but the envisioned process might be applied to other functional, formal, and spatial typologies. The design of the pavilion starts with the generation of a surface, later tessellated into a matrix of skylights depending on the geographic location and sun orientation. In the constructed pavilion, the skylights react to the variation of daylight intensity during the day to satisfy specified internal lighting needs. Simultaneously, the integration of conception and fabrication using digital tools (CAD-CAM) facilitates the construction of a non-standard, parametric geometry, thereby diminishing the costs of production and allowing for personalization, while assuring global sustainability.

summary Recent introduction and coupling of digitally mediated design and production environments facilitated a radical deviation from the traditional ways of using representations, knowledge assets, organizational forms and standards. Consequently, we observe an abundance of the traditional views of design and the emergence of new cognitive models/constructs based on the emerging relationships between the designer, the design object (artefact), the design tools/systems and the organizational network of the various actors and their activities in building design & production. The paper reports on the initial findings of an ongoing research which aims to uncover the ways in which digitalization and digital tools have recently been adopted to the work practices of multidisciplinary firms and the evolving socio-technical networks and organizational infrastructures within architectural practice.

summary This paper will relay the initial phase of a collaborative work within partners from the design discipline, systems engineering, and software engineering which deals with the interrelations of “network idea”, “systems thinking”, “collective design”, and “computation”. Vensim– a system dynamics modelling tool developed by Ventana Systems, Inc. in 1992 – has been used in an experimental first year design studio to engage students in systems thinking in the architectural design environment. It has been observed that this tool enabled most students to develop a multi-layered, complex and more controlled design logic and to amplify the cognitive processes at the beginning of the design education. We conclude that in order to fully realize systems thinking in the design process, new ways of integrating parametric design environments and system dynamic modelling environments needs to be investigated.

summary Relationships are amplified and collapsed together as animate surfaces in the formal and spatial manifestation of design parameters. Animation is demonstrated as a medium to express topologies, as each frame is the resultant of a programmed serious of computations, the result of which varies with a parameter: effectively, time. Related conditions are parameterized through the design of algorithms as a means of direct translation into animation. Interrelated forces and limits can conversely congeal into statics with animate qualities. Process and product merge to create a language of phenomenological effects and patterns. While animation is exploited to represent parametric relationships there is a maintained awareness of time and space. The systemization and codification of design “problems” simultaneously facilitates functional, solution-driven architecture. The output is characterized by complex, performative, and specific solutions uniquely relevant to emerging models for fabrication and construction. Usage requirements and site conditions carry the weight of information-based contexts and experience-based symbols as fuel for the inherently cyclical process.

summary Acoustics are important performance criteria for architecture; however, architects rarely consider them, except, perhaps, when designing concert halls. Architectural spaces can be said to perform well or poorly in terms of their acoustic qualities. By altering the geometry or material characteristics of the surfaces within a room in specific ways, the acoustics can be controlled. Once the geometric rules governing these acoustic alterations are understood, these rules can be encoded into a CAD system through parametric modeling or the use of computer programming. The architectural designer can then generate acoustically regulating surfaces according to desired performance criteria. In this way, acoustic engineering links to architectural design, and allows architectural design to become acoustically performance-driven. This paper considers three primary types of acoustic surfaces: absorbers, resonators, and diffusers. complex surfaces that combine these three performance characteristics in different ways are proposed.

title Towards Morphogenesis in Architecture
source International Journal of Architectural Computing vol. 7 - no. 3, 345-374
summary Procedural, parametric and generative computer-supported techniques in combination with mass customization and automated fabrication enable holistic manipulation in silico and the subsequent production of increasingly complex architectural arrangements. By automating parts of the design process, computers make it easier to develop designs through versioning and gradual adjustment. In recent architectural discourse, these approaches to designing have been described as morphogenesis. This paper invites further reflection on the possible meanings of this imported concept in the field of architectural designing. It contributes by comparing computational modelling of morphogenesis in plant science with techniques in architectural designing. Deriving examples from case-studies, the paper suggests potentials for collaboration and opportunities for bi-directional knowledge transfers.

In the case study shown here, architectural geometry is related to structural morphology; as part of a larger process, its parameterization aims at supporting further performance related investigations, including thermal aspects, by meaning of both the large scale investigation and a more detailed level of design.

summary The delivery of a successful project demands high levels of collaboration across an expanded design team, which now includes consultants, fabricators and contractors as well as architects and engineers. The pace of development in design technology has been very rapid during the last few years and there are now many software products which offer high levels of sophistication. Most provide associative and parametric modelling strategies, which can be further enhanced and extended by the use of scripting languages. Designers are becoming tool-builders while fabricators are becoming digital craftsmen. With the advent of fast efficient drawing extraction the industry is at last making determined steps towards a model-driven process. However there is no integrated platform which supports the free exchange of ideas, combined with the evaluation of performance, experimentation with production techniques and the evolution of project-specific workflows. In education the design schools have been quick to recognise the potential of the new design technology. This has led to a rapid expansion in course curricula that now offer many new specialisations, most of which also need to be under-pinned by a good grounding in descriptive geometry, mathematics and physics. The architect as a generalist, who coordinates the work of specialists, is being challenged by an increasing breadth of technical studies that require more than just a superficial depth of understanding. In practice the gulf is widening even more rapidly. New graduates, who often have spectacular expertise in modelling and fluency in scripting languages, do not yet have the design and construction experience necessary to direct their efforts to best effect. On the other hand people running project teams do not have the technical background to understand the potential of the skills and resources that are available. Today there is no longer the continuity that used to derive from apprenticeship. As we experiment we find that tools based on new ideas and techniques can radically change workflow – but fear of the unknown can provoke resistance. So the problems we face in harnessing the new technology are as much social and cultural as they are technical. The presentation will focus on developing attitudes towards tool-building with the aim of integrating design, analysis and production. This is part of a continual and quite gradual process, which requires the ability to play interpretive roles that help to bring about cultural change. Examples will be shown from the work of the Specialist Modelling Group at Foster+Partners who now have tenyears experience in deploying design technology in an environment where research is intensely project driven.

summary A potential way to bridge the gap between complex form generation and models for physical manifestations is to panelize NURBS surfaces with polygonal faces. This paper investigates the transition from NURBS surface to a mesh solid through a procedural modeling approach, in the process, illustrating how a discretized planar surface can be reconstructed for form generation and further exploration. The paper promotes this approach as an efficient way to modeling complex forms using an example drawn from real life architecture to demonstrate a generative process with customized restructuring.

title The Use of the Smart Geometry through Various Design Processes: Using the programming platform (parametric features) and generative components
source Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 297-304
summary The emergence of parametric generative design tools and prototyping manufacturing technology led to radical changes in architectural morphologies. This change increased the opportunity to develop innovative smart geometries. Integrating these algorithms in the parametric softwares led to variations in building design concepts increasing alternatives and decreasing the repetitive work previously needed in conventional CAD software. The chosen software in this research is Generative Components (GC). It is a software design tool for an associative and parametric design platform. It is tested for using Global Variables with associative functions during the concept creation and form GC comprises features. The results presented in this research may be considered an introduction to the smart geometry revolution. It deals with the generative design which applied in the design process from conceptual design phase, defining the problem, exploring design solutions, then how to develop the design phases. Office building is a building type which encourages new forms that needs computational processes to deal with repetitive functions and modular spaces and enclosed in a flexible creative structural skin. Generative design helps the office buildings to be arranged, analysed, and optimized using parameters in early stages in design process. By the end of the research, the use of the smart geometry in a high rise office building is defined and explained. The research is divided into three parts, first a summary of the basic theories of office buildings design and the sustainable requirements that affect it, and should be integrated. Secondly, the previous experiences in generating office buildings by Norman foster and Sergio Araya. At last, a case study is proposed to test and evaluate the use of the parametric generative methodology in designing an office building with specific emphasis on the function, environmental aspects and form generation using Generative Components (GC) Software.

title From texture to volume: an investigation in quasi-crystalline systems
source SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary The relation between texture, pattern and massing is a fundamental question in architecture. Classical architecture, as Leon Battista Alberti states in “De re aedificatoria” (Book VI, Chapter 2), is developed through massing and structure first; texture is added afterwards to give the bold massing and structure beauty. Only the ornamentation adds pulcritudo to the raw structure and massing. Rather than starting with a volume and applying texture afterwards, the Digital Girih project started with textural operations that informed the overall volume later. The stereometric, top-down methodology is questioned through the bottom-up methodology of the Girih project. Girih lines of traditional Islamic patterns were used as a starting point. The aspect of 3-dimensionality was developed analogue as well as digital, using the deformability of different materials at various scales and digital construction techniques as parameters. The flexibility within the Girih rules allowed the system to adapt to different tasks and situations and to react to different conditions between 2- and 3- dimensionality. The project in that way explored a bottom-up process of form generation. This paper will describe the process of the project and explain the necessity of digital tools, such as Grasshopper and Rhino, and fabrication tools, such as laser cutter and CNC fabrication technology, that were essential for this process.
