summary The utilization of point cloud as a 3D laser scanning product has reached across multi-disciplines in terms of data processing, data visualization, and data analysis. This study particularly investigates further the use of typical attributes of raw point cloud data consisting of XYZ (position information), RGB (colour information) and I (intensity information). By exploring the optical and thermal properties of the given point cloud data, it aims at compensating the material and texture information that is usually remained behind by architects during the conceptual design stage. Calculation of the albedo, emissivity and the reflectance values from the existing context specifically direct the architects to predict the type of materials for the proposed design in order to keep the balance of the surrounding Urban Heat Island (UHI) effect. Therefore, architects can have a comprehensive analysis of the existing context to deal with the microclimate condition before a design decision phase.

summary This paper describes the Pelourinho Project realized past July in Salvador, during the 1st International Conference on 3D Laser Scanning for Heritage Documentation. The Pelourinho located at the historic center of Salvador, is an impressive wide set of buildings listed by UNESCO as World Heritage. The text contains a quickly overview about the 3D laser scanning technology, shows how data are captured and what they stored and what they means. The 3D laser scanning model, another kind of 3D geometric model is called point cloud and represents an excellent way to store data of some particular constructions. Because its irregular shapes it is very arduous to survey and represent these constructions by any other method. The point cloud model is an excellent way to represent with integrity and accuracy these particular complex shapes like the colonial baroque churches in Brazil. [Full paper in Portuguese]

summary This ongoing investigation aims to learn from nature novel material organizations and structural systems in order to develop innovative architectural system. We developed a multidisciplinary approach, using scientific analysis and design research and prototyping. We focus on the study of a “living fossil” fish, whose armor system is so efficient it has remained almost unchanged for millions of years. We investigate its morphological characteristics, its structural properties, the assembly mechanisms and the underlying material properties in order to derive new principles to design new enhanced structural systems. We use micro computerized tomography and scanning electron microscopy to observe microstructures, parametric design to reconstruct the data into digital models and then several 3D printing technologies to prototype systems with high flexibility and adaptive capabilities, proposing new gradual material interfaces and transitions to embed performative capabilities and multifunctional potentials.

title From 2D Base Map To 3D City Model
source UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, I.17-I.28
summary Since 1997 Helsinki City Survey Division has proceeded in experimenting and in developing the methods for converting and supplementing current digital 2D base maps in the scale 1:500 to a 3D city model. Actually since 1986 project areas have been produced in 3D for city planning and construction projects, but working with the whole map database started in 1997 because of customer demands and competitive 3D projects. 3D map database needs new data modelling and structures, map update processes need new working orders and the draftsmen need to learn a new profession; the 3D modeller. Laser-scanning and digital photogrammetry have been used in collecting 3D information on the map objects. During the years 1999-2000 laser-scanning experiments covering 45 km2 have been carried out utilizing the Swedish TopEye system. Simultaneous digital photography produces material for orto photo mosaics. These have been applied in mapping out dated map features and in vectorizing 3D buildings manually, semi automatically and automatically. In modelling we use TerraScan, TerraPhoto and TerraModeler sw, which are developed in Finland. The 3D city model project is at the same time partially a software development project. An accuracy and feasibility study was also completed and will be shortly presented. The three scales of 3D models are also presented in this paper. Some new 3D products and some usage of 3D city models in practice will be demonstrated in the actual presentation.

title Computer in Creation of Architectural Form
source AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999,pp. 131-142
summary This paper considers graphic methods of presentation of ideas 'in the creation of architectural forms' and evolution of these methods, determined by the implementations of information technology. Drawings have been the main medium of expression since Leonardo da Vinci to the present-day. Graphic communication has always been treated as a main design tool, both - at the ending stage of design and at the early design stage. Implementation of computers in design doe not change this situation. The entire design process proceeds in a traditional way. While searching for the idea we use hand sketches and, after this, technical drawings are draught on a plotter, which replaces a drawing pen. Using computers at the early design stages encounters serious difficulties. The main thesis of this paper is that hardware and software inadequacy is not the problem, the problem is in the inadequacy of the design methods. This problem is to be reconceived as what a person can do with a program, rather than what is the capacity of a program. Contemporary computer techniques allow us to put an equation mark between the searching for idea, visualisation and its realisation in virtual space. This paper presents Sketching by scanning - an experimental method of using computer hardware and software for stimulating of searching of architectural's form.

summary The aim of this work is to try to set out how new technologies can influence the perception of a museum exposition. The problem which will be analysed is how to adapt an exhibition to the needs of visually impaired people. The problem will be considered on the basis of the case studies which were the part of an agreement between the Army museum in Bialystok and our Faculty. In traditional museums the main principle is the prohibition of touching exhibits.The project goal was to help blind people understand the features of the environment around them through the sense of touch. The novelty of this work is the study of how new digital technologies may improve the perception for the visually impaired.In the paper the method of 3D scanning, modelling and 3D printing will be presented. In conclusion the encountered problems and plans for further action will be discussed.

title Media interaction and design process: establishing a knowledge base
source Automation in Construction 9 (1) (2000) pp. 37-56
summary Integrating computers in architectural design means to negotiate between centuries-old analog design methods and the new digital systems of production. Analog systems of architectural production use tracing paper, vellum, graphite and ink, clipboard, clay, balsa wood, plastic, metal, etc. Analog systems have also been termed "handmade", "manual", "material" or "physical". Digital systems of architectural production use scanning, image manipulation, visualization, solid modeling, computer aided drafting, animation, rendering, etc. Digital systems have also been called "electronic", "computer-aided", "virtual", etc. The difficulty lies in the underdeveloped state of the necessary methods, techniques, and theories to relate traditional and new media. Recent investigations on the use of multiple iterations between manual and electronic systems to advance architectural work show promising results. However, these experiments have not been sufficiently codified, cross-referenced and third party tested to conform a reliable knowledge base. This paper addresses this shortcoming by bringing together reported experiences from diverse researchers over the past decade. This summary is informed by more than three years of continuous investigation in the impacts of analog-digital conversations in the design process. The goal is to establish a state-of-the-art common foundation that permits instructors, researchers and practitioners to refer to, utilize, test, criticize and develop. An appendix is included providing support for the paper's arguments.

summary This study experiments a process of production of tactile representations of architectural elements of a nineteenth century mansion, house to a university museum: Museu do Doce, Pelotas, RS. The Museum uses the concept of Universal Design to guide its direct and/or mediated communication solutions. The house is distinguished by ceilings of ornamental stuccoes, evidently perceived only by the sense of sight. To describe them, a set of representations is being produced, using 3D scanning and digital fabrication technologies, using formal decomposition, and different scales, to construct a narrative to be understood by touching.

title Skin That Fits: Designing and constructing cladding systems with as-built structural data
source Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 236-245
summary An awkward interface exists between the structure and skin of complex architecture. The primary structure is typically allowed much higher tolerance ranges than that of the cladding industry, due primarily to the delicate nature of the building envelope which, above all, must prevent water penetration and meet the aesthetic requirements of the architect and client. As architecture has integrated advanced design and fabrication techniques to realize increasingly complex shapes, this problem has been aggravated because of the tangency requirements for high gloss curved finish surfaces and the larger variations found with rolled steel columns and undulating concrete forms. To date, most innovations in this area have been focused upon mechanical connections that can be adjusted and shimmed, thus requiring increased design engineering and on-site labor costs for effective implementation. It would be preferable to manufacture cladding components that are properly adjusted to the actual site conditions, negating the need to predict and accommodate potential dimensional variation with complex connections. The research provides a model for implementing long distance laser scanning technology to facilitate a real-time parametric BIM, herein called an Isomodel.

title Rapid Production of Virtual Reality City Models
source GIS - Geo-Informationssysteme 12(3), pp. 22–28
summary The growing demand for detailed city models has stimulated research on efficient 3D data acquisition. Over the past years, it has become evident that the automatic reconstruction of urban scenes is most promising if different types of data, possibly originating from different data sources are combined. In the approach presented in this paper the geometric reconstruction of urban areas is based on height data from airborne laser scanning and 2D GIS, which provides the ground plan geometry of buildings. Both data sources are used to estimate the type and parameter of basic primitives which in turn are combined to obtain complex building structures. The final output consists of 3D CAD models for the buildings. Using the reconstructed geometry, terrestrial images are mapped onto building facades to generate virtual city models.

title Towards Fully Automatic Generation of City Models
source IAPRS Vol. XXXIII, Part B3/1, Comm. III [ISPRS Congress], pp. 85-92
summary Once thought of being useful primarily for planning the location of telecommunication antennas, it has become clear in the meantime that three-dimensional city models are of importance in their own right. This paper presents some of our latest results on the reconstruction of building models from laser scanning DSM’s and digital ground plans. First, we show how buildings can be reconstructed from ground plans and generalize the standard straight skeleton algorithm. In a second step, we introduce the information which can be obtained from DSM segmentation in order to recover building structures which cannot be inferred directly from the ground plan. The work presented in this paper is actually part of our larger ATOP approach, a new framework for the fully automatic generation of city models.

summary This paper investigates the potential of behavioral construction strategies for architectural production through the design and robotic fabrication of three-dimensional woven structures inspired by the behavioral fabrication logic used by the weaverbird during the construction of its nest. Initial research development led to the design of an adaptive robotic fabrication framework composed of an online agent-based system, a custom weaving end-effector and a coordinated sensing strategy utilizing 3D scanning.The outcome of the behavioral weaving process could not be predetermined a priori in a digital model, but rather emerged out of the negotiation among design intentions, fabrication constraints, performance criteria, material behaviors and specific site conditions. The key components of the system and their role in the fabrication process are presented both theoretically and technically, while the project serves as a case study of a robotic production method envisioned as a soft system: a flexible and adaptable framework in which the moment of design unfolds simultaneously with fabrication, informed by a constant flow of sensory information.

Its purpose was to gather information that will subside the future acquisition of a 3D-scanning equipment for the Laboratory for Automation and Prototyping for Architecture and Construction, LAPAC, at the University of Campinas (UNICAMP). In order to test some of these technologies, some experiments were carried out. Museum sculptures were digitized and the results were 3D-printed. Preliminary results show that accurate technologies are still very expensive, but there are some alternative, more accessible technologies, based on photogrammetry, which can lead to fairly good results.

source First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 65-76
summary CeramiSKIN is an inter-disciplinary investigation examining recursive patterns found in organic matter. Through the use of digital capture and translation techniques, these biophilic systems may serve as topological generators for structural and ornamental consequences well-suited to mass-customizable ceramic cladding systems for architecture. Digital information is acquired through laser scanning and confocal electron microscopy, then deformed using particle physics engines and parametric transformations to create a range of effects promulgated through digital fabrication techniques. This inquiry is primarily concerned with two questions: Is it possible that natural systems may be digitally captured and translated into biophilic structural forms and/or ornamental effects that may foster beneficial responses in humans? / Since natural orders eschew rigid manifold geometries in favor of compound plastic shapes, is it possible to fabricate mass-customized, large-scale biophilic ceramic cladding from organic digital data?
