title	The Role of Virtual City Models in Urban Tissue Evaluation
doi	https://doi.org/10.52842/conf.ecaade.2002.396
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 396-399
summary	The shape of town is the main issue which planners deal with. The function of some buildings and urban facilities is flexible, it changes in time. The appearance of city public areas and, what follows, the life conditions of its inhabitants, depends on elements of the town structure - the surrounding buildings, their density, state and form. All lasting elements of the city form its shape which reflects urban processes which have been taking place over ages. The aim of this paper is to define how latest computer technology can be used as an aid in the evaluation of the town landscape.

title	Robotic Equilibrium: Scaffold Free Arch Assemblies
doi	https://doi.org/10.52842/conf.acadia.2018.342
source	ACADIA // 2018: Recalibration. On imprecisionand infidelity. [Proceedings of the 38th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-17729-7] Mexico City, Mexico 18-20 October, 2018, pp. 342-349
summary	Compression only arch structures are structurally highly efficient in force equilibrium. However, the material efficiency is offset by the traditional use of scaffolds to position materials and counter the out of equilibrium forces during assembly. We introduce a method of sequentially assembling compression only structures without a scaffold by robotically maintaining the compression equilibrium in every step. A two-arm collaborative robotic setup was used to maintain force equilibrium throughout arch assembly with the arms taking turns first hot wire cutting and placing blocks and providing a temporary scaffold to support the arch end point. To test the approach, a single catenary arch was generated using form-finding techniques and sequentially built from foam blocks. Moving forward we show the relationship between the joint valence (largest number of joined branches) of a multi-branched structure and the minimum number of robotic arms required for assembly using our initial technique. With only two robotic arms available, the technique was further developed to reduce the required number of arms per arch branch from two to one by attaching caterpillar tracks at the block supporting end effector. This allows a human to load the next block and the arm to move forward along the arch while maintaining equilibrium. Results show that robotic equilibrium scaffold free arch assembly is possible and can reduce scaffold waste and maintain the material efficiency of compression only structures. Future work will explore further applications of assistive robotics in construction replacing static construction aids with dynamic sensory feedback of equilibrium forces.

title	Methods for Geometrical Examination of Physical Settings - In the Quest for a Modus Operandi in Culture Specific Urban Design
doi	https://doi.org/10.52842/conf.ecaade.2015.1.361
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 1, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 361-368
summary	The current paper develops and extends the methodology of the geometrical description of urban outdoor places, formerly defined as the index keys method. The previously defined features of street and square profiles and skylines, i.e.: central angle, regularity and corrugation, are further completed with variations which develop into a clear, mathematical explanation of the basic notions defining genius loci, including the scale and atmosphere of a place. Altogether, the geometrical analysis defined here stems from the descriptions of urban settings with regard to culture related issues. It also reveals some of the morphological processes in the transformation of urban settings which took place in the discussed locations. The algorithmic method, namely the use of Grasshopper scripting, has been applied for the automation of the process. The preliminary results of analyses are presented as well as further research pathways.

title	Towards Understanding the Complexity of Urban Culture - A case study of Jewish communities in pre-war central Poland
doi	https://doi.org/10.52842/conf.ecaade.2016.2.049
source	Herneoja, Aulikki; Toni Österlund and Piia Markkanen (eds.), Complexity & Simplicity - Proceedings of the 34th eCAADe Conference - Volume 2, University of Oulu, Oulu, Finland, 22-26 August 2016, pp. 49-58
summary	The current paper presents the experience of mapping pre-war Jewish communities in central Poland during a period of intensive social and cultural transformations. The initial analytical framework, provided thanks to the GIS database and concatenation of attributes coming from various sources, makes some initial observations and conclusions possible. It confirms the thesis that Jewish communities in pre-war Poland may be considered an example of a self-organising society, one which could be considered a prototype of contemporary postmodern cultural complexity. The current study provides the initial framework to map the morphology and spatial distribution of the complexity of everyday culture of use of space proper to this extremely diverse group.

title	A Generative Approach to Social Ecologies in Project [Symbios]City
doi	https://doi.org/https://doi.org/10.1007/978-981-16-5983-6_2
source	Proceedings of the 2021 DigitalFUTURES The 3rd International Conference on Computational Design and Robotic Fabrication (CDRF 2021)
summary	The following paper talks about the studio project [Symbios]City, which is developed as a design research project in 2020–2021 Schumacher’ studio on social ecology of the graduate program in Architectural Association’s design research lab. The project aims to create an assemblage of social ecologies through a rich but cohesive multi-authored urban district. The primary ambition is to generate an urban area with a characterful, varied identity, that achieves a balanced order between unity and difference avoiding both the sterile and disorienting monotony of centrally planned modernist cities and the (equally disorienting) visual chaos of an agglomeration of utterly unrelated interventions as we find now frequently. Through a thorough research process, our project evolves mainly out of three principles that are taken into consideration for the development of our project: topological optimization, phenomenology, and ecology. By “ecology”, we understand it as a living network of information exchange. Therefore, every strategy we employ is not merely about reacting to the weather conditions, but instead it is an inquiry into the various ways we can exploit the latter, a translation of the weather conditions into spatial and programmatic properties. [Symbios]City therefore aims at developing a multi-authored urban area with a rich identity that achieves a balance between the various elements. [Symbios]City began formally from topological optimization, developed based on studies on ecology, and concluded the design following our phenomenological explorations, aiming at a complex design project that unifies the perception of all scales of design: from the platform to the skyscrapers.

title	Improvement of the horizontal directional drilling method by using an autonomous land vehicle with a radio direction finding system
source	Automation in Construction 11 (1) (2002) pp. 75-88
summary	This article discusses the improvement in the horizontal directional drilling method (HDD) by using an autonomous land vehicle (ALV) with a radio directional finding (RDF) system. The ALV with an RDF system carrying a receiver can locate a moving or static underground drill head and track it. Not limited to a pre-determined track or path, the ALV system utilizes its on board RDF system instantaneously to seek and to track a moving or static drill head. Compared to conventional systems, the system reduces the number of operators, minimizes labor costs, prevents accidents, and enhances the degree of automation.The design of the RDF system and how to locate a target are considered in this article. To overcome the difficulty in obtaining the precise dynamic model of the ALV with the RDF system, a "fuzzy logic controller" is designed to control such a system and make the system capable of tracking a target. Experimental results verify that such an RDF ALV system can track a moving or static target.

title	Form Finding and Evaluating Through Machine Learning: The Prediction of Personal Design Preference in Polyhedral Structures
doi	https://doi.org/https://doi.org/10.1007/978-981-15-6568-7_13
source	Architectural Intelligence Selected Papers from the 1st International Conference on Computational Design and Robotic Fabrication (CDRF 2025)
summary	3D Graphic Statics (3DGS) is a geometry-based structural design and analysis method, helping designers to generate 3D polyhedral forms by manipulating force diagrams with given boundary conditions. By subdividing 3D force diagrams with different rules, a variety of forms can be generated, resulting in more members with shorter lengths and richer overall complexity in forms. However, it is hard to evaluate the preference toward different forms from the aspect of aesthetics, especially for a specific architect with his own scene of beauty and taste of forms. Therefore, this article proposes a method to quantify the design preference of forms using machine learning and find the form with the highest score based on the result of the preference test from the architect. A dataset of forms was firstly generated, then the architect was asked to keep picking a favorite form from a set of forms several times in order to record the preference. After being trained with the test result, the neural network can evaluate a new inputted form with a score from 0 to 1, indicating the predicted preference of the architect, showing the possibility of using machine learning to quantitatively evaluate personal design taste.

title	Floating bubbles: an agent-based system for layout planning
doi	https://doi.org/10.52842/conf.caadria.2010.175
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 175-183
summary	This program converts bubble diagram into an agent-based system for architectural design. The program suggests a model for layout planning based on bubble diagram which explicitly describes the adjacency requirements in architecture. Generally there is a basic set of rules for every agent dealing with adjacency topology and also an alternative set for other objectives. Then this basic program is developed into several generative tools for different design tasks. They imply that the agent-based system is efficient for elementary spatial arrangement and it could generate a wide range of complex solutions.

title	Text Semantics to Image Generation: A Method of Building Facades Design Base on Stable Diffusion Model
doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_3
source	Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
summary	Stable Diffusion model has been extensively employed in the study of architectural image generation, but there is still an opportunity to enhance in terms of the controllability of the generated image content. A multi-network combined text-to-building facade image generating method is proposed in this work. We first fine-tuned the Stable Diffusion model on the CMP Facades dataset using the LoRA (Low-Rank Adaptation) approach, then we apply the ControlNet model to further control the output. Finally, we contrasted the facade generating outcomes under various architectural style text contents and control strategies. The results demonstrate that the LoRA training approach significantly decreases the possibility of fine-tuning the Stable Diffusion large model, and the addition of the ControlNet model increases the controllability of the creation of text to building facade images. This provides a foundation for subsequent studies on the generation of architectural images.

doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_32
source	Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
summary	Recent developments in digital architecture have placed a renewed focus on sustainable architectural materials and the circularity of material systems. Algae has emerged as a promising material for mitigating the effects of climate change due to its ability to absorb large amounts of carbon dioxide. However, the disposal of algal biomass can lead to significant CO2 emissions and air pollution. The upcycling of algae into composite materials can promote circular economies by reducing the demand for petroleum-based products. In this context, this research explores the potential of Ulva algae in creating 3D-printed architectural prototypes based on bio-algorithm. An experimental analysis of the material properties of algae-based plastic is conducted and compared to similar reference products. This study argues for the importance of designing and fabricating these materials at the required scale while leveraging bio-thinking principles to create closed-loop systems and maximize the potential of natural resources.

title	Kerf Guided Glulam - A novel way of creating curved glulam beams
doi	https://doi.org/10.52842/conf.ecaade.2022.1.085
source	Pak, B, Wurzer, G and Stouffs, R (eds.), Co-creating the Future: Inclusion in and through Design - Proceedings of the 40th Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2022) - Volume 1, Ghent, 13-16 September 2022, pp. 85–90
summary	This paper proposes a novel way of producing curved glulam timber elements where the formwork is integrated into a glulam beam. The method proposed accomplishes this by placing kerf cuts on a timber profile that gets bent and then encased in a wood laminate, forming the glulam beam. The kerf placement allows the beam to be asymmetrically curved. The optimal placement for the kerf cuts is found by feeding an initial goal curve to a form-finding definition that subdivides it and places markers where cuts need to be made while manipulating the beam geometry, ensuring that it matches the initial input curve. The benefit of this method is that it is not reliant on large-scale glulam setups but can be fabricated with basic wood workshop tools in conjunction with a 5-axis CNC mill. The simplified production process enables smaller manufacturers and designers to produce dynamic wooden structures while saving on materials and labour that would have gone into producing formwork that eventually gets discarded.

title	Associative Spatial Networks in Architectural Design - Artificial Cognition of Space using Neural Networks with Spectral Graph Theory
source	Design Computation Cognition conference 2010
summary	This paper looks at a new way of employing unsupervised neural networks in the design of an architectural system. The method described involves looking the whole lifecycle of a building and its coupling with its environment. Techniques such as dimensionality reduction, it is argued, are well suited to architectural design whereby complex problems are commonplace. An example project is explored - that of an exhibition space where multiple ephemeral exhibitions are housed at any given time. A modified growing neural gas algorithm is employed in order cognize similarities of spaces whose nature are not known a priori. By utilising the machine, a coupling between the building system and the users of the space is explored throughout the whole project life of the design.

title	Biomorpher: Interactive evolution for parametric design
source	International Journal of Architectural Computing vol. 16 - no. 2, 144-163
summary	Combining graph-based parametric design with metaheuristic solvers has to date focused solely on performance-based criteria and solving clearly defined objectives. In this article, we outline a new method for combining a parametric modelling environment with an interactive Cluster-Orientated Genetic Algorithm. In addition to performance criteria, evolutionary design exploration can be guided through choice alone, with user motivation that cannot be easily defined. As well as numeric parameters forming a genotype, the evolution of whole parametric definitions is discussed through the use of genetic programming. Visualisation techniques that enable mixing small populations for interactive evolution with large populations for performance-based optimisation are discussed, with examples from both academia and industry showing a wide range of applications.

title	Evolving Parametric Models using Genetic Programming with Artificial Selection

summary	Evolutionary methods with artificial selection have been shown to be an effective human-computer technique for exploring design spaces with unknown goals. This paper investigates an interactive evolution of visual programs currently used in popular parametric modelling software. Although parametric models provide a useful cognitive artifact for designers to interact with, they are often bound by their topological structure with the designer left to adjusting (or optimising) metric variables as part of a design search. By allowing the topological structure of the graph to be evolved as well as the parameters, artificial selection can be employed to explore a wider design space more suited to the early design stage.

summary	Many proposals using object-oriented data models for engineering objects have appeared in the literature. These data models try to represent the data in engineering systems more naturally by organizing it logically and/or physically into objects relevant to the engineering applications using the database. The article reviews and examines several of these proposed data models to identify important properties of the models. It shows that none of the data models excels in all areas, but each has desirable properties

source	FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.805-814
summary	It is perhaps no longer relevant to discuss digital tools purely as means in themselves; the growth of abstract systems or computational patterns for their own sake simply strain justification in light of real-world concerns such as climate change and economic crises. While growing concerns over climate change have necessitated an increased interest in sustainable urbanism and design, sustainability has done little to yet alter the morphological and typological consequences of architectural space (Hardy, 2008). In a series of overlapping research projects and design studio briefs, students, research assistants and we worked with the iterative and variable processes of Rhinoscript, McNeel’s Grasshopper and Bentley’s Generative Components to explore the possibilities of changing environmental extremes (specifically flooding) as catalysts for providing new urban morphologies and spatial organizations. Working between the master plan and the individual housing unit, we investigated arrays of terrace homes in the London Thames Valley flood zones while simultaneously exploring the potential for computational generation and parametric optimization.

summary	In the current era, the utilization of 3D positioning maps for Augmented Reality (AR) registration is becoming increasingly prevalent, particularly in indoor guidance. This research endeavors to investigate issues related to the construction of 3D positioning maps and their application in navigation by developing an AR-guided app for a historical and cultural park. The study reveals that the use of 3D positioning maps enables the precise and stable presentation of virtual information within specific physical spaces. A majority of participants reported a positive AR navigation experience using this app. However, challenges arise when applying 3D positioning maps in outdoor settings, where factors such as tree shadows and the lack of distinctive patterns on asphalt roads can impact positioning quality. Ideally, environments with distinctive patterns are better suited for presenting AR content through 3D positioning maps. The findings of this research serve as valuable insights for future developments in map-based AR navigation systems.

summary	This book captures and binds disparate streams of information in a single volume and attempts to reconnect us to the experience of architecture through holding a book in our hands. Just as architecture uses the connections among the dissimilar as the sites for design intervention and invention, the content of this book attempts to connect the objective processes that are characteristic of computers with the subjective processes that are characteristic of creativity. The chosen format juxtaposes technical work in the first half with pedagogical explorations in the second half. By recognizing their differences and separating them from each other, the process of reconnecting can occur. Within both the technical and pedagogical sections, a continuous stream of information connects the papers across the bottom of the page. Against the technical papers, we have placed the keynote paper by Professor Paul Laseau. Against the pedagogical papers, we have placed a drawing done by Trent Tesch that is a visual interpretation of cyberspace based on the novel, Neuromancer, by William Gibson. While turning these pages, consider the accidents that take place through the juxtaposition of streams of thought sharing a single page.
