title	Generative Systems:Intertwining Physical, Digital and Biological Processes, a case study
doi	https://doi.org/10.52842/conf.ecaade.2019.1.025
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 1, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 25-34
summary	The fourth Industrial Revolution is characterised by the computational fusion of physical, digital and biological systems. Increasing information in terms of size, speed and scope exponentially. This fusion requires improved, if not new, tools and methods to deal with complexity and information processing. By opening Generative Systems to interact with the context, we believe that they can develop solutions that are more adequate for our time. This research began with a literature review about generative systems and their application to solve problems. We then selected the tools, Cellular Automata, L-Systems, Genetic Algorithms and Shape Grammar, and thought about how to translate these original mathematical tools to specific design situations. We tested the application of these tools and methods in a workshop, implementing recursive loops to open these techniques to interference. Analysing the empirical results made us revise our design thinking, relying on the study of complexity to understand how these techniques can be more context-aware, so we can make design evolve. Finally, we present a comparative framework analyses that interlaces techniques and methods, so in the future we can merge physical, digital and biological information.

title	ViBe (Virtual Berlin) - Immersive Interactive 3D Urban Data Visualization - Immersive interactive 3D urban data visualization
doi	https://doi.org/10.52842/conf.ecaade.2019.3.083
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 3, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 83-90
summary	The project investigates the possibility of visualizing open source data in a 3D interactive virtual environment. We propose a new tool, 'ViBe'. We programmed 'ViBe' using Unity for its compatibility with HTC VIVE glasses for virtual reality (VR). ViBe offers an abstract visualization of open source data in a 3D interactive environment. The ViBe environment entails three main topics a) inhabitants, b) environmental factors, and c) land-use; acting as representatives of parameters for cities and urban design. Berlin serves as a case study. The data sets used are divided according to Berlin's twelve administrative districts. The user immerses into the virtual environment where they can choose, using the HTC Vive controllers, which district (or Berlin as a whole) they want information for and which topics they want to be visualized, and they can also teleport back and forth between the different districts. The goal of this project is to represent different urban parameters an abstract simulation where we correlate the corresponding data sets. By experiencing the city through visualized data, ViBe aims to provide the user with a clearer perspective onto the city and the relationship between its urban parameters. ViBe is designed for adults and kids, urban planners, politicians and real estate developers alike.

title	Visual Impact Analysis of Large Urban Investments on the Cityscape
doi	https://doi.org/10.52842/conf.ecaade.2019.3.297
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 3, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 297-304
summary	The article presents the assessment method for large (horizontally spread) urban investment and its visual impact on the cityscape using digital analyses. The visual impact assessment is often used in relation to facilities which dominate in the cityscape, mainly tall buildings. Various studies, however, examine the impact of wide but relatively low-rising buildings and their impact on the cityscape. The article presents a methodology for the assessment of the visual impact and a case study for a building facility comprising several tightly developed and medium height blocks of buildings in a city center of a significant historical value in Gdañsk, Poland. The research has been based on the Visual Impact Size method (VIS) and a city model consisting of a regular cloud of points (Digital Surface Model). The simulation has been developed using a dedicated C++ software (developed by author). The study aimed at assessing the following: a) to what degree such an urban investment can influence the cityscape; b) how the impact can be analyzed using digital techniques, and c) what input parameters of the analysis are crucial for satisfactory accuracy of its results.

title	Home Mobility Hazards Detected via Object Recognition in Augmented Reality
doi	https://doi.org/10.52842/conf.ecaade.2019.2.415

summary	We present an Environmental Analysis and Safety Advisor system capable of identify the environmental barriers and hazards found in the homes of elderly people. This augmented reality tool runs on a portable computing device and can be used by informal and formal caregivers without specific knowledge of Accessible Design, to evaluate the safeness of an elderly home environment, ensuring that potential fall hazards are detected and corrected. The system recognizes specific indoor elements of the house (e.g. arm-chair, bed, chair), and then computes and analyses their mutual distances in the environment so that a warning of hazard is emitted in case of need (e.g. loose cable, not enough space to pass a wheelchair). In this context, we implemented object recognition at the category level of miniature versions of real sized furniture and the determination of the distance between neighboring objects, signaling if it is below a certain threshold value. Environmental Analysis tool can then recognize furniture and measure the distance between two furniture elements enabling the system to pop up an alert sign if the space left does not guarantee good accessibility.

summary	This paper approaches the literature that combines the fields of Architectural Computing and Architecture and Urbanism produced in Latin America during the first two decades of the 21st Century. The main objective is to map the advancement of Digital Technology in Architecture and Urbanism in the context of the Third Industrial Revolution, in order to identify perspectives towards a Fourth Industrial Revolution. As methodology was applied a chronological survey of the literature produced in book format, predominantly printed in the 21st Century by Latin Americans researches in leading digital themes. At last, it can be verified that the production is still very scarce and still has not incorporated, in a significant way, the themes related to the Fourth Industrial Revolution.

title	Bio-Modules - Cyber-physical modular responsive variations for dark urban areas using bio-degradable materials
doi	https://doi.org/10.52842/conf.ecaade.2019.2.495
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 2, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 495-504
summary	This paper documents the design and fabrication process of modular responsive lighting installation. The design and research led to a modular and transformable urban lighting concept, combining unique material behaviour and cyber-physical system. The main goal was to investigate how material characteristics, composition and performance could be programmed in order to generate a range of modular components. Modular tiles and joints combination designed of sustainable materials - bioplastics and cork sheets - were created and used together with number of sensors and micro-controllers. Furthermore, the installation concept links technical and psychological aspects that potentially could be used for the benefits of city dwellers. Paper consists of two parts. First part is the introduction of a broader urban night lighting design context to which the project belongs. This includes covering existing social issues related to urban darkness, as well as the need to increase biodiversity within built environment, through introducing new materials. The second part of the paper describes the design and fabrication process, that employs the conclusions discovered in the first part through set of material experimentations, design project and the reflections on the results.

title	Semi-flexible Additive Manufacturing Materials for Modularization Purposes - A modular assembly proposal for a foam edge-based spatial framework
doi	https://doi.org/10.52842/conf.ecaade.2019.1.463
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 1, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 463-470
summary	This paper introduces a series of design and fabrication tests directed towards the use of bendable 3D printing materials in order to simplify a foam bubble-based geometry as a frame structure for modular assembly. The aspiration to reference a spittlebug's bubble cocoon in nature for a light installation in the urban context was integrated into a computational workflow conditioning light-weight, material-, and cost savings along with assembly-simplicity. Firstly, before elaborating on the project motivation and background in foam structures and applications of 3D-printed thermoplastic polyurethane (TPU) material, this paper describes the physical nature of bubble foams in its relevant aspects. Subsequently this is implemented into the parametric design process for an optimized foam structure with Grasshopper clarifying the need for flexible materials to enhance modular feasibility. Following, the additive manufacturing iterations of the digitally designed node components with TPU are presented and evaluated. Finally, after the test assembly of both components is depicted, this paper assesses the divergence between natural foams and the case study structure with respect to self-organizing behavior.

title	Protection of the waterfront panoramas based on computational 3D-analysis
doi	https://doi.org/10.52842/conf.ecaade.2019.2.325
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 2, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 325-332
summary	The article presents the application of the Visual Protection Surface (VPS) method in protecting waterfront panoramas. The digital analysis of visual impact, which is most frequently used in urban planning, assesses the impact of new investment on the cityscape. The study presented in the article is based on a reverse approach -determining the maximum height of buildings so new facilities do not distort protected vistas in a city, vistas which are crucial for the preservation of the city's cultural identity and spatial identification. The assessment of the application is based on a case study of Gdañsk, Poland, where a 3D LiDAR model was used. The study involved the use of software developed by the author (C++). It also analyzed VPS input parameters. Conclusions can be used to assess and verify analysis findings with different software (GIS/CAD). The article shows the potential application of the VPS method in urban planning.

summary	The introduction of digital fabrication technologies in Latin America faces diverse, heterogeneous and decentralized conditions. After several years, there was not a comprehensive perspective on the situation in the region. The goal of this paper is to present a project called "Homo Faber: Digital Fabrication in Latin America" and some of its results. The project comprehends the creation of a database that led to researches and exhibitions about digital fabrication in design, architecture and building construction in Latin America. The questions that guide the investigation try to understand which factors contribute and limit the potential of automation in material processes towards 4.0 industry.

summary	Digital architecture developed in the 1960s and, supported by CAAD the 1990s, has created the path towards an architecture produced by computer and architect in a mutual relationship. The evolution of architecture since the 1970s led to the beginning of the first digital turn in the 1990s, and subsequently to the emergence of new typologies of buildings, architects and design tools; atom-based, bit-based (virtual) [1], and cyber-physical as a combination of both. The paper provides an insight into historical foundations of CAAD insofar as it engages with complexity in mechanics, geometry, and space between the 1600s and 1950s. I will address a selection of principles discovered, and mechanisms invented before computer-aided-architectural-design; those include the typewriter, the Cartesian grid and a pre-cyber-physical system by Hermann von Helmholtz. The paper concludes with a summary and an outlook to the future of CAAD challenged by the variety of correlations of disparate data sets.

title	Implementing the Santa Marta Urban Grammar - a pedagogical tool for design computing in architecture

summary	We present a tool intended to enable non-expert users to apply and manipulate a shape grammar, SMUG, which encodes the urban design of informal settlements such as favelas. Such tool, the Interpreter, was developed considering that students would be its main users, and therefore we consider this grammar implementation to potentially be a multipurpose pedagogical tool since it supports conveying knowledge about urban design, shape grammars and parametric modeling using Grasshopper. This paper focuses on the development of the Interpreter and discusses the results of its use in a design studio, which can better inform subsequent iteration as well as other courses and schools.

title	Informal Settlements and City Information Modeling - Producing data to inform land use regulation in Fortaleza-Brazil
doi	https://doi.org/10.52842/conf.ecaade.2019.3.323
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 3, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 323-332
summary	In recent years, several advances have occurred concerning the legitimacy of precarious informal settlements in Brazil. In spite of this progress in the legal dimension, little has been made concerning standards to ensure urban space quality. The difficulties of reversing this exclusionary logic are due to several complex factors. A factor less discussed, especially in the national literature, but that has begun to draw the attention of scholars, is the invisibility of the informal city. This research assumes that it is necessary to regulate the urban form of precarious informal settlements, in order to prevent the deterioration of urban environmental quality. We highlight the importance to compile data about their urban form and their built environment, in order to contribute to a reality-based regulatory policy for these settlements, and this is the primary purpose of this study. To address this question, we propose a method of measuring the settlements' urban form, based on the City Information Modeling's theorical and practical framework, which is applied to a case study in Fortaleza, Brazil.

summary	Location-based mobile applications have been a rising theme for academics in the field of urbanism and in urban and transportation, because of the potential of transformation they might bring to the urban landscape (De Souza e Silva, 2013). One of the possibilities we study here is to observe social encounters fostered by commuting rides. In this paper, we try to examine the practice from the broad perspective of estimating the environmental benefits, in a context where digital information technology is wielded to address problems old and new (Townsend, 2014). This paper aims to analyze the potential of transformations that new ICTs bring to urban mobility, using as case study the official ridesharing system of the Federal University of Rio de Janeiro, the Carona? project. The system was developed focusing on the reduction of the number of motorized trips to the University, as well as the amount of CO2 generated by them. Here we analyze the dynamics of ridesharing, using the system data, and also try to observe the role it may play towards the promotion of integration in the UFRJ community.

summary	In this paper, we are aiming to present a methodology for generation, manipulation and form finding of structural typologies using variational autoencoders, a machine learning model based on neural networks. We are giving a detailed description of the neural network architecture used as well as the data representation based on the concept of a 3D-canvas with voxelized wireframes. In this 3D-canvas, the input geometry of the building typologies is represented through their connectivity map and subsequently augmented to increase the size of the training set. Our variational autoencoder model then learns a continuous latent distribution of the input data from which we can sample to generate new geometry instances, essentially hybrids of the initial input geometries. Finally, we present the results of these computational experiments and lay out the conclusions as well as outlook for future research in this field.

summary	The paper will give an overview of our experiments in the past years in developing different interfaces and workflows for the use of low cost Head Mounted Displays (HMD) for Virtual Reality solution. We are mainly interested in using VR tools for designers in the early phases of their design. In our opinion VR tools can help to bring back a better understanding of space and scale which have been lost a little bit in the last century with the change from analogue to digital tools. After teaching architectural and urban design for many years we can clearly say that this effect is still ongoing and it is time that we develop digital tools that try to reverses thi effect. We will then concentrate within this paper on discussing some aspects of data reduction that are important to be able to use these tools in the design process. We are also showing how we use our interfaces presenting some results of student projects for a design in Hong Kong and the strategies and methods for using VR for a ongoing work on a project about the establishment of a so called "bicycle highway" in the city of Graz in Austria.

title	A Framework for a Five-Axis Stylus for Design Fabrication

summary	This paper proposes a new workflow between design and fabrication phases through the introduction of a novel framework centered around a stylus that is tracked in real-time for five-axis by a single RGB-D camera. Often misconceived as a linear process, urgent reinterpretation of design and fabrication tools is discussed briefly. Similar to how industrial robots have become an enabler for fabrication process in the field of architecture and construction, the necessity for providing a similar tool that would reform the "design" process is underlined. A generic stylus is proposed with interchangeable operations which allows for intuitive, non-obstructive grasp of the user serves as the physical avatar that transform into a virtual representation of a fabrication tool mounted on a six-axis industrial robot arm. User interaction with the apparatus is simulated for the user, and the user is notified of any errors as the interaction is translated for motion planning of a KUKA KR20-3 industrial robot.

title	Integrating BIPV during Early Stages of Building Design
doi	https://doi.org/10.52842/conf.ecaade.2019.2.139
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 2, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 139-144
summary	In the quest to achieve the ambitious climate and clean energy targets the broad implementation of Integrated Photovoltaics (BIPV) is one of the keys. Photovoltaic (PV) modules can be installed above or on current roofing or traditional wall structures. In addition, BIPV devices substitute the skin of the exterior construction frame, i.e. the weather screen, thus simultaneously acting as both a climate screen and an energy producing source. However, while the integral planning strategy to building projects promotes the effective execution of BIPV, the limitation lies in the absence of both instruments and easy-to-use planning aid guidelines, particularly by non-PV experts in the early design stage. This study presents computational methods that help to quickly analyze the BIPV potential for a given building project and to suggest the optimal economical amount and location of the panels based on the building's energy demand profile.

summary	This essay is related to the research project "The immersive experience in 360°: investigation, representation and digital immersion in the city of Rio de Janeiro in the 19th and 20th centuries", developed at PROURB in FAU-UFRJ, Rio de Janeiro/Brazil. This work will investigate the Panorama of Rio de Janeiro looking for memories and historical truths in its context: Which part represents a historical point of view? Which part is invention? How were the city and its landscape represented on the canvas? As the most well-known Rio de Janeiro's panorama, which project was idealized by the Brazilian painter Victor Meirelles de Lima (1832-1903) and the Belgian photo-painter Henri Charles Langerock (1830-1915), it was exhibited in Brussels 1888, Paris 1889, and Rio de Janeiro 1891-1896, with great recognition in all these cities. This paper will explore this Panorama, its initial studies, its landscape and the architecture depicted, newspapers descriptions of its exhibitions, and mainly, distinguishing among memories, historical truths and verisimilitudes. In order to achieve these objectives, digital and analogical systems of representations, sketches and computer graphics techniques, specially, tridimensional models will be developed and applied.

summary	This paper describes an implementation of the CityMetrics toolbox, in order to provide a dynamic assessment of metrics related to walkability, diversity and density in remote and low-income urban areas. The applied methodology was used in two remote neighborhoods of Juiz de Fora, which is a Brazilian city, in a case study. The objective was to identify and to evaluate a set of weaknesses in the addressed areas and to propose some improvements in the neighborhoods´ arrangements. The ultimate goal is to contribute to a better understanding of urban problems according to walkability, diversity and density, as well as to contribute to the discussion on the design and implementation of low-income real estate developments, facilitating the management of solutions in urban planning processes in this context.
