summary The Catoptric Surface research project explores methods of reflecting daylight through a building envelope to form an image-based pattern of light on the interior environment. This research investigates the generation of atmospheric effects from daylighting projected onto architectural surfaces within a built environment in an attempt to amplify or reduce spatial perception. The mapping of variable organizations of light onto existing or new surfaces creates a condition where the perception of space does not rely on form alone. This condition creates a visual effect of a formless atmosphere and affects the way people use the space. Often the desired quantity and quality of daylight varies due to factors such as physiological differences due to age or the types of tasks people perform (Lechner 2009). Yet the dominant mode of thought toward the use of daylighting tends to promote a homogeneous environment, in that the resulting lighting level is the same throughout a space. This research project questions the desire for uniform lighting levels in favor of variegated and heterogeneous conditions. The main objective of this research is the production of a unique facade system that is capable of dynamically redirecting daylight to key locations deep within a building. Mirrors in a vertical array are individually adjusted via stepper motors in order to reflect more or less intense daylight into the interior space according to sun position and an image-based map. The image-based approach provides a way to specifically target lighting conditions, atmospheric effects, and the perception of space.

summary This paper discusses a collaborative project by RDAI architects, Bollinger+Grohmann and the timber construction company Holzbau Amann. The project is located in a former swimming pool in Paris and it is part of the new interior of a flagship store of the French fashion label Hermes. In late 2009, Rena Duma Architects, asked Bollinger+Grohmann to collaborate as structural engineers on a challenging design proposal within a very short timeframe. Three wooden lattice structures, the so-called “bulle” and one monumental staircase with a similar design approach characterize the interior of the new flagship store. The lattice structures are dividing the basement into different retail spaces. They vary in height (8-9 m) and diameter (8-12 m) and have a free-form shaped wicker basket appearance. Wood was the chosen material for these structures to strengthen the idea of the wickerbaskets and to create an interior space with a sustainable and innovative material.

title Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 477-492.
summary Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call “business views”. We propose a 4 steps-method to compose business views. The first step identifies the users’ business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user’s interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

summary This paper aims at specifying how ‘digital’ acts in contemporary architectural design. On that purpose, and in an a priori manner, we will formulate hypotheses of concepts able to translate the specificities of digital design. In this research paper, we beg the question that the ‘digital culture’ may influence the architects in two manners: in design operation and in references. The conceptual tools will be given by architecturology, and our hypotheses will be illustrated with examples of two French firms (Ateliers Jean Nouvel, Jakob+MacFarlane).

title Using Computers to Aid Creativity in the Early Stages of Design – or Not!: Rehabilitating the 2D/3D physical representation in Computer-Aided-Ideation
doi https://doi.org/10.52842/conf.ecaade.2009.761
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. 761-768
summary The introduction of Rapid Prototyping technology such as 3D printers and diverse Numerically Controlled machines such as laser cutters and milling machines, has made it obvious for many educational institutions, that a paradigm shift is occurring these years, that will forever change the design- and architectural practice, - for better or worse. This paper discusses the current change of role and status of the representation as a means to communicate design in the digital era. It outlines two opposite directions for the development of software technology, and brings forward previous and current research, on the didactic aspects of introducing digital software into the curriculum of architecture and design education. The paper describes a workshop held at the Danish Design School, where students proficient in using digital media, were challenged to use analogue models instead, to rediscover and utilize some of the creative potentials offered by this medium. Two other workshops discussing similar themes with different foci and different participants have been held since. One hosted by the Glass & Ceramic School on Bornholm, where the students are trained as traditional Craftsmen and another hosted by Nordes2009 at AHO in Oslo, where the participants came with a background in the research community. My own research interest lies in establishing or refueling a discussion on the importance of the ambiguity in a physical representation, as opposed to the finite interpretations offered by the digital modeling environment, that the profession is accustomed to work within. This interest has recently been confirmed and renewed by reading “The (soft) Architecture Machine(s)” from 1970+75 and by studying the works of Professor Julio Bermudez and Professor Bennett Neiman.

title From Digital Heritage Documentation to 3D Virtual Reconstruction and Recreation for Heritage Promotion and Reinterpretation: The Case of the iHeritage Project
source C+++: Computation, Culture, and Context – Proceedings of the 11th International Conference of the Arab Society for Computation in Architecture, Art and Design (ASCAAD), University of Petra, Amman, Jordan [Hybrid Conference] 7-9 November 2023, pp. 7-23.
summary In the last two decades, the digital age Information and Communication Technologies (ICT) development and concerns combined with rapid technology have permitted the dissemination of different digital applications (including digital documentation, virtual reality (VR), augmented reality (AR), mixed reality (MR), digital gaming, and holograms etc.) oriented toward past, present and future communication using digital three-dimensional audio-visual content. Today, we must acknowledge that 3D virtual 3D reconstruction and recreation has become an established way to build, understand, reinterpret, and promote Cultural Heritage (CH). The virtual 3D reconstruction world and multimedia industry are often considered potential marketing channels for World Heritage Sites (WHS) and heritage tourism. 3D digital/virtual reconstruction merges and embodies subjectivity in one process, playing an attractive role in heritage tourism destinations and creating image experiences, providing the first enjoyable interpretation and information for most audiences. Based on the EU-funded iHERITAGE project ICT Mediterranean platform for the UNESCO CH, this paper attempts to examine some insights into constructing the optimistic image of heritage promotion and tourism in the context of CH as it flows through both physical and virtual spaces to give a glimpse of the future of virtual reconstruction. It illustrates the development of the concepts and practice, challenges and opportunities, advantages and disadvantages, and the negative and the positive sides of the related issues of only 3D digital reconstructions, and some issues concerning the ethics based on the International Chartres and Conventions mainly in the field of scientific visualisation, such as the London Charter (2009) and Seville Principles (2011). Finally, as a practical dimension, it presents some representative examples of 3D digital/virtual reconstruction of characteristic monuments of the WHS of Nabataean Petra in Jordan for the first time.

title Monitoring Archaeological Site Landscapes in Cyprus using Multi-temporal Atmospheric Corrected Image Data
source International Journal of Architectural Computing vol. 7 - no. 1, 121-138
summary This paper aims to examine the use of satellite remote sensing for monitoring archaeological and more generally cultural heritage sites. For this purpose, multi-temporal data from Landsat 5 TM, Landsat 7 ETM+ and Quickbird images were applied. The paper also discusses the importance of atmospheric correction at the pre-processing step in order to determine true surface reflectance values by removing these effects from satellite images. Atmospheric correction is arguably the most important part of the pre-processing of satellite remotely sensed data and any omission produces erroneous results. The effects of the atmosphere are more severe where dark targets are shown in the satellite image. In the management of cultural heritage sites, since temporal satellite images are required for monitoring purposes, the effect of the atmosphere must be considered. In-situ spectro-radiometric measurements using the GER1500 field spectro-radiometer have been used to assess the reflectance values found after applying the darkest pixel atmospheric correction to the image data. The study area consist the Amathus archaeological site in Limassol and the Nea Paphos archaeological site area located in Paphos district area in Cyprus. Vegetation Index (NDVI) change detection algorithm has been applied to a series of thirteen Landsat TM/ETM+ images of Amathus archaeological site in Limassol. Classification and extraction algorithms have been applied to Landsat TM and Quickbird high resolution images of Nea Paphos archaeological site area.

title Programming framework for architectural design ANAR+: Object oriented geometry
source T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 771- 785
summary From the recent advent of scripting tools integrated into commercial CAAD software and everyday design practice, the use of programming applied to an architectural design process becomes a necessary field of study. The presented research explores the use of programming as explorative and reflexive medium (Schön, 1983) through the development of a programming framework for architectural design. Based on Java, the ANAR+ library is a parametric geometry environment meant to be used as programming interface by designers. Form exploration strategies based on parametric variations depend on the internal logic description, a key role for form generation. In most commercial CAD software, geometric data structures are often predefined objects, thus constraining the form exploration, whereas digital architectural research and teaching are in need for an encompassing tool able to step beyond new software products limitations.

title When is Generative Design Design?
doi https://doi.org/10.52842/conf.ecaade.2009.x.f3p
source Computation: The New Realm of Architectural Design [27th eCAADe Conference] Istanbul (Turkey) 16-19 September 2009
summary The question in my title is neatly put in a counterfactual: HOW WOULD CALCULATING BE DIFFERENT IF TURING WERE AN ARTIST OR DESIGNER AND NOT A LOGICIAN? A generative process – in design or wherever calculating is tried – uses recursive rules. But RECURSION alone isnʼt design. EMBEDDING is needed, as well. This entails a switch from blindly following rules to seeing what happens. Then calculating in Turingʼs way by counting is a special case of calculating in an artistʼs or designerʼs way by seeing. And creativity as recursion – in logic, linguistics, and computer science – extends to art and design. Generative design is design if thereʼs embedding, that is to say, anytime thereʼs seeing. Usually, seeing is outside a generative process, when it stops and you look at the results. What recursive rules imply may not be what you see. But embedding works with recursion, so that rules let you see as you go on inside a generative process. Seeing starts anew – without stopping – every time a rule is tried. Recursion and embedding together make generative design design. This is summarized in a formula: GENERATIVE DESIGN + EMBEDDING = DESIGN // The equivalence is a useful heuristic for new research in calculating, and for art and design.

title Interactive Hemostasis Modeling in Urban Network Design
source International Journal of Architectural Computing vol. 7 - no. 3,375-387
summary This paper describes a type of project that images a city as it might exist given the integration of hemostatic procedures within pedestrian networks during emergencies requiring full-scale egress from an urban core. It articulates the steps taken to integrate a pre-existing C++ hemostasis model (C. Jacob, 2008) into Maya software in order to describe how the project operates on a computational level. By projecting these agent-based logics directly into/onto each pedestrian in the city (the smallest unit of the system), egress-oriented infrastructure can shift from being extensively predetermined in form (concrete barriers, metal railing, police barricades, etc.), to something more intensively defined, real-time, and locally on-demand. These procedures are situated within a larger schema based on the structural principles of Norbert Wiener's cybernetic feedback loops, that acknowledge and allow for hybrid (top-down + bottom-up) awareness and control within systems. The project attempts to ally itself with emerging forms of network design with similar structural typologies supported through the use of personal mobile devices (PMDs) in urban environments.

summary This study is divided in two areas. First, investigating the architectural, structural and possible program qualities of the egg crate. The fundamental exchange between the mathematical realm -in the form of digital modeling- and the material realm – in the form of material prototype fabrication and manufacturing- is the second goal. This paper also focuses on a basic design problem: how to produce a system of variable cavities and niches as opportunities for adjust to different programmatic needs as well as different terrain conditions based on the egg crate construction method. The egg crate was first used as a conventional aspect of masonry systems of construction, from wooden boats to building hulls. Simply put, it’s a matrix of horizontal and vertical structural elements (or parallel to the x and y axis). The findings were incorporated into the design of prototypes for small-scale urban furniture / installations, the “Légumes urbaines”.

title Social Experiments in Design Technology

source Computation: The New Realm of Architectural Design [27th eCAADe Conference] Istanbul (Turkey) 16-19 September 2009
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 Recently, the handling of information design by architects was motivated by the progress and exploration of digital technologies. They began to experiment with the use of informational metaphors and their application in virtual environments. This paper presents these new experimentations in 3D information visualization designed by architects interested in experimentation with digital media as information environments in design. The examples presented in this paper attempt to demonstrate the design of information and aim to illustrate approaches to the representation of the structure and relationships within abstract datasets. The architectural exploitation of metaphors may constitute unique formulations of knowledge structures capable of communicating information in unique ways.

summary Ahead of the digital environments expansion which follows the principles of the web 2.0, one can notice a growing opening for user's participation. The proposal of this research is to reflect on how this scenario of participation is strengthening a social structure capable of actively acting not only in the production of digital content, but also in the form of this content presentation. From a survey of cases and a theoretical review, this paper aims to analyze two different types of user’s influence on the visual dimension of web environments. One first - adaptive layout - based on the indirect user’s action and a second - layout’s customization - based on the direct user’s action.

title Automatic Extraction of Planar Clusters and their Contours on Building Facades Recorded by Terrestrial Laser Scanner
source International Journal of Architectural Computing vol. 7 - no. 1, 1-20
summary Since 3D city models need to be realistic not only from a bird's point of view, but also from a pedestrian's point of view, the interest in the generation of 3D façade models is increasing. This paper presents two successive algorithms for automatically segmenting building façades scanned by Terrestrial Laser Scanner (TLS) into planar clusters and extracting their contours. Since majority of façade components are planes, the topic of automatic extraction of planar features has been studied. The RANSAC algorithm has been chosen among numerous methods. It is a robust estimator frequently used to compute model parameters from a dataset containing outliers, as it occurs in TLS data. Nevertheless, the RANSAC algorithm has been improved in order to extract the most significant planar clusters describing the main features composing the building façades. Subsequently, a second algorithm has been developed for extracting the contours of these features. The innovative idea presented in this paper is the efficient way to detect the points composing the contours. In order to evaluate the performances of both algorithms, they have successively been applied on samples with different characteristics, i.e. densities, types of façades and size of architectural details. Finally, a quality evaluation based on the comparison of planar clusters and contours obtained manually has been carried out. The results prove that the proposed algorithms deliver qualitative as well as quantitative satisfactory results and confirm that both algorithms are reliable for the forthcoming 3D modelling of building façades.
