summary The research paper exemplifies a novel information integrated design technique developed at ONL (Oosterhuis and Lenard), Netherlands, specifically appropriated for envisaging complex geometric forms. The ‘informed design technique’, apart from being highly instrumental in conceptualizing and generating the geometric component constituting architectural form in a parametric manner, is also efficiently utilized for precise computer aided manufacturing and construction of the speculated form. Geometric complexities inherent in contemporary architectural constructs and the time spent in appropriation of such topologies, fueled the ‘informed design’ approach, which caters to issues of timely construction, precision oriented design and production (visual and material) and parametric modeling attuned to budgetary fluctuations. This design-research approach has been tested and deployed by ONL, for conceiving ‘the Acoustic Barrier’ project, Utrecht Leidsche Rijn in the Netherlands and is treated as a generic case for exemplifying the ‘informed design’ technique in this research paper. The design methodology encourages visualizing architectural substantiations from a systems perspective and envisages upon a rule based adaptive systems approach involving extrapolation of contextual dynamics/ground data in terms of logical ‘rules’. These rules/conditionalities form the basis for spawning parametric logistics to be mapped upon geometric counterparts exemplifying the conception. The simulated parametric relations bind dimensional aspects (length, width, height etc.) of the geometric construct in a relational manner, eventually culminating in a 3D spatial envelope. This evolved envelope is subsequently intersected with a ‘parametric spatio-constructive grid’, creating specific intersecting points between the two. The hence extorted ‘point cloud’ configuration serves as a generic information field concerning highly specific coordinates, parameters and values for each individual point/constructive node it embodies. The relations between these points are directly linked with precise displacements of structural profiles and related scaling factors of cladding materials. Parallel to this object oriented modeling approach, a detailed database (soft/information component) is also maintained to administer the relations between the obtained points. To be able to derive constructible structural and cladding components from the point cloud configuration customized Scripts (combination of Lisp and Max scripts) process the point cloud database. The programmed script-routines, iteratively run calculations to generate steel-wireframes, steel lattice-structure and cladding panels along with their dimensions and execution drawing data. Optimization-routines are also programmed to make rectifications and small adjustments in the calculated data. This precise information is further communicated with CNC milling machines to manifest complex sectional profiles formulating the construct hence enabling timely and effective construction of the conceptualized form.

title Digital Historic Heritage: documenting of Pelourinho, Salvador - Bahia, Brazil, with 3D laser scanning technology
source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 673-678
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]

title A Representation Language for a Prototype CAD Tool for Intelligent Rooms
doi https://doi.org/10.52842/conf.acadia.2005.170
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. 170-183
summary Intelligent rooms are a type of intelligent environment which enhance ordinary activities within the confines of a room by responding to human interaction using pervasive and ubiquitous computing. In the design of intelligent rooms, the specification of how the intelligent room enacts intelligent behavior through computational means is as integral as the geometric description. The self-aware and context-aware capabilities of intelligent rooms extend the requirements for computer-aided design tools beyond 3D modeling of objects. This article presents a Hardware as Agents Description Language for Intelligent Rooms (HADLIR) to model hardware in an intelligent room as “hardware agents” having sensor and/or effector modalities with rules and goals. End-users describe intelligent room hardware as agents based on the HADLIR representation and write agent rules and goals in Jess for each hardware component. This HADLIR agent description and the requisite software sensors/effectors constitute “hardware agents” which are instantiated into a multi-agent society software environment. The society is then bridged to either a virtual environment to prototype the intelligent room or to microelectronic controllers to implement a physical intelligent room. The integration illustrates how the HADLIR representation assists in the design, simulation and implementation of an intelligent room and provides a foundation technology for CAD tools for the creation of intelligent rooms.

title Multi-touch - the future of design interaction
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. 557-572.
summary The next major revolution for design is to bring the natural user interaction into design activities. Graphical User Interfaces (GUI) brought a new approach that was more effective compared to their conventional predecessors. In recent years, Natural User Interfaces (NUI) have advanced user experiences and multi-touch and gesture technologies provide new opportunities for a variety of potential uses in design. Much attention has been paid to leverage in the design of interactive interfaces. The mouse input and desktop screen metaphors limit the information sharing for multiple users and also delayed the direct interaction for communication between each other. This paper proposes the innovative method by integrating game engine ‘Unity3D’ with multi-touch tangible interfaces. Unity3D provides a game development tool as part of its application package that has been designed to let users to focus on creating new games. However, it does not limit the usage of area to design additional game scenarios since the benefits of Unity3D is allowing users to build 3D environments with its customizable and easy to use editor, graphical pipelines to openGL (http://unity3d.com/, 2010 ). It creates Virtual Reality (VR) environments which can simulates places in the real world, as well as the virtual environments helping architects and designers to vividly represent their design concepts through 3D visualizations, and interactive media installations in a detailed multi-sensory experience. Stereoscopic displays advanced their spatial ability while solving issues to design e.g. urban spaces. The paper presents how a multi-touch tabletop can be used for these design collaboration and communication tasks. By using natural gestures, designers can now communicate and share their ideas by manipulating the same reference simultaneously using their own input simultaneously. Further studies showed that 3Dl forms are perceived and understood more readily through haptic and proprioceptive perception of tangible representations than through visual representation alone (Gillet et al, 2005). Based on the authors’ framework presented at the last CAADFutures, the benefits of integrating 3D visualization and tactile sensory can be illustrated in this platform (Chen and Wang, 2009), For instance, more than one designer can manipulate the 3D geometry objects on tabletop directly and can communicate successfully their ideas freely without having to waiting for the next person response. It made the work more effective which increases the overall efficiency. Designers can also collect the real-time data by any change they make instantly. The possibilities of Uniy3D make designing very flexible and fun, it is deeply engaging and expressive. Furthermore, the unity3D is revolutionizing the game development industry, its breakthrough development platform for creating highly interactive 3D content on the web (http://unity3d.com/ , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

title DESKTOP VIRTUAL ENVIRONMENTS IN CONSTRUCTION EDUCATION
source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 725-730
summary In construction science, classroom oriented education remains the preferred mode of teaching. Alternative methods such as field trips, use of 3D drawings, and physical models often supplement and enhance the understanding of students. In addition to the risks involved with field trips, designated sites may not be at the particular stage of construction during the academic semester, or the construction sequence may not be fast enough to demonstrate the multiple facets during field visits. Considerable pedagogical advantages can be achieved by the integration of IT and visualization tools in teaching construction engineering/technology. The objective of this research was to develop a desktop virtual environment using 3D, animations, virtual reality and walkthrough of construction processes of steel, concrete, and lightwood structures. These visualization techniques can be valuable aids not only in teaching in the classroom but also an effective self-directed tool for open learning via the web.

title From CAD to VR – Implementations for Urban Planning and Building Design
doi https://doi.org/10.52842/conf.ecaade.2005.399
source Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 399-405
summary At present time, three-dimensional objects are often represented with 2D-data in urban planning and building design. In order to get all the involved parties to fully understand a certain project, this may not be enough. More and more projects therefore take use of the Virtual Reality (VR) technique as a complement to traditional 2D drawings and sketches. All the involved parties can then share a common frame of reference for all discussions regarding a certain project. Unfortunately, the technique is not yet adapted to fit the current building design process. In this paper, we present a solution for semi-automatic generation of a VR-model based on 3D CAD information and aerial photos obtained from the City Planning Authorities in Sweden. The data is imported to support real-time editing of terrain, roads and buildings. We also present a framework for importing 3D-models created in Autodesk Revit which enables a seamless integration of modern 3D CAD and VR-models. The features are implemented in a software developed at Chalmers Visualization studio (Gothenburg, Sweden) and technical details about terrain handling and speed-up techniques will be given.

title The Nazca Lines and their Digital Architectural Representation
doi https://doi.org/10.52842/conf.caadria.2007.x.r9m
source CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary This paper relates to a digital architectural design experience in 2005 for the Nazca Competition. Nazca is an archaeological site situated about 400 kilometers south of Lima, Peru. It is a large desert with gigantic millenary geoglyphs carved on the surface, which can only be seen clearly from above. The Nazca geoglyphs are made up of hundreds of lines, spirals and triangular plazas, as well as zoomorphic figures like birds, fish, spider, etc. The Nazca Competition asked for an observatory-lodge of approximately 1.000m2 with 20 rooms, communal bathrooms, supporting areas and an observatory tower of at least 100 meters. The observatory-lodge was designed using a digital representation technique called "Genetically Constructed Structures". The structure was created using the geometric principle of the affinity of two conic sections: circle and ellipse. The form was produced transforming the circle and the ellipse by performing basic geometric transformations (translation, rotation, reflection and scaling). According to this technique, the sequence of transformations was codified in the form of an alphanumerical string, metaphorically named the "DNA structure". The code was inserted as extended data into the entities which shaped the structure profiles. The algorithms were programmed with AutoLISP language. The "DNA code" allowed the structure to be constructed and deconstructed from any point, generating many different forms, to be studied and compared. One year later, the same 3D model was used to test another digital technology called "musical box" where their geometrical points are captured, read and translated into musical parameters, generating music. In this paper we will present the graphical form of the tower as well as the music associated.

summary This paper looks at ways in which recent developments in sensing technologies and gestural control of data in 3D space provide opportunities to interact with information. Social and spatial data, the utilisation of space, flows of people and dense abstract data lend themselves to visual and auditory representation to enhance our understanding of socio-spatial patterns. Mapping information to visualisation and sonification leads to gestural interaction with information representation, dissolving the visibility and tangibility of traditional computational interfaces and hardware. The purpose of this integration of new technologies is to blur boundaries between computational and spatial interaction and to transform building spaces into responsive, intelligent interfaces for display and information access.

title DecoSketch – Towards Calligraphic Approaches to Interior Design
doi https://doi.org/10.52842/conf.ecaade.2005.665
source Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 665-670
summary Computer-Aided Design tools have long played an important role in architecture design. However, we need to go beyond direct manipulation to devise new tools that will expedite the interior design and decoration. Indeed, conventional CAD systems, while providing ever increasing functionality, do not provide equal support to the drafting and drawing tasks. This makes even the simplest drawings a complicated endeavor. Draftspeople struggle with different concepts that those learnt from their earlier days in school and have to think long and hard to translate familiar sequences of operations to commands which require navigating a dense jungle of menus. The term calligraphic interfaces was coined by us to designate a large family of applications organized around the drawing paradigm, using a digital stylus and a tablet-and-screen combination as seen most recently in Tablet PCs®. Using these, users can enter drawings in a natural manner, largely evocative of drafting techniques that were perfected for pencil-and-paper media. This paper presents a simple calligraphic interface to explore interior design literally from the ground up. The Decosketch application is a modeling and visualization tool structured around 2 _D architectural plants. Its purpose is to help architects or customers easily creating and navigating through house designs starting from the floorplan and moving to their three-dimensional representation. Moreover, both 2D and 3D representations can be independently edited, providing a natural interface that tries to adhere to well-known representations and idioms used by architects when drafting using pencil and paper.

source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 344-349
summary The goal of this research is to describe a methodology of architectural design by using digital technology with three-dimensional interactive simulation in multi-user virtual worlds. In addition, this study will focus on the application of this method in the workshops at the School of Architecture in the University of Zulia. With this proposal, it is possible to integrate many users, in real time, from different locations on the same virtual world in Internet. In the same way, each visitor is able to interact and modify the virtual world using virtual menus while sharing ideas or modifications regarding the design of the project. This strategy allows modeling, visualizing, developing and evaluating the designed projects during the conceptual and parametric phase in the process of design. This application is a powerful tool to develop creativity and skills of spatial perception among the students. [Full paper in Spanish]

summary This paper presents the advancements of the Urbamedia project which was designed as part of a research program at the Center CAO (Creation computer assist), School of Architectural Design and Urbanism, University of Buenos Aires, which was led by the valued master and advisory professor Architect Arturo F. Montagu. This proposal of the city of Buenos Aires on the Mayo Avenue expands the original historical fragment presented between the following two referenced representative landmarks: The Two Congresses Square and the Mayo Square. It continues with the advancement of methodologies and techniques implemented in a system of “integrated visualization and communication” for the development of a VRML (Virtual Reality Modeling Language) 3D virtual non-immersive and interactive vision. It also incorporates the development of a “foundation of digitally integrated knowledge” with fragments of central areas from other surrounding cities as well as interfaced phenomenological situations. The application of digital VRML technology has allowed for thoroughly researching the processes through dynamic simulation of specific urban fragments (Mayo Avenue within Buenos Aires) and the cities that are also participating in the project.

title Generating Architectural Spatial Configurations: two approaches using voronoi tessellations and particle systems
source Proceedings of the Generative Arts conference, Milan, 2005
summary It was one of the primary goals of the original Master’s programme in Computing and design at UEL in 1991 that we should work towards defining morphological generative processes for the conceptual design of architectural objects. These two papers offer a range of techniques which have been developed by two of this years MSc students (04-05) which show that we are getting close to this. The approaches range from computational geometric approaches (3d parametrics and voronoi diagrams) to emergent spatial organisation using agent based modelling. In many cases the resultant geometry is defined to the point where it can be transferred to advanced evaluation and fabrication systems, thus making this work sufficiently developed to begin to form a useful part in practical design processes.

summary The Nâgara tradition of temple building created a rich corpus of Latina (single-spired) temples spread across Northern India between the fifth and thirteenth centuries. Computing methods offer a distinct methodology for reconstructing the genesis and evolution of geometry in this tradition over time. This paper reports a hybrid technique, comprising three distinct computations for recovering and explaining the geometry of temples. The application of the technique enables scholars to bring together fragments of evidence, construe “best-fit” strategies and unearth implicit or hidden relationships. The advantage of this approach is that changes in assumptions and testing of geometric alternatives can be easily simulated from multiple sources of information, such as texts, sacred diagrams and individual temples.

summary The project deals with the use of residual wood of tree stumps and roots through scanning, optimization and robotic milling. Wood logging residue makes up to 50 percent of the trees harvested biomass. (Hakkila and Parikka 2002). Among prevailing strategies is leaving residue on site, and recovering residue for bioenergy. (Perlack and others 2005). The project explores the third strategy, using parts of the logging residue for fabrication, which may reduce the overall amount of wood logging volume. Furthermore approach aims for applying residue in its natural form and taking advantage of specific local characteristics of wood (Desch and Dinwoodie 1996). The project applies the strategy on working with stump and roots of an oak tree. Due to considerations of scale, available milling technics and available resources, chosen goal of the approach is to create a functioning chair prototype. Among the problems of the approach is the complex shape of the residue, uneven quality of wood, varying humidity and contamination with soil. After cleaning and drying, the stump is scanned and a 3D model is created. The 3D model od a stump is confronted with a 3D modelled limits of the goal typology (height, width, length, sitting surface area and overal volume of a chair) and topological optimization algorithm is used to iteratively reach the desired geometry. Unlike in established topological optimization proces, which aims for a minimal volume, the project attempts to achieve required qualities with removing minimal amount of wood. Due to geometric complexity of both stump and goal object, milling with an 6axis industrial robotic arm and a rotary table was chosen as a fabrication method. The object was clamped to the board (then connected to a rotary table) in order to provide precise location and orientation in 3D space. The milling of the object was divided in two parts, with the seating area milled in higher detail. Overall process of working with a residual wood that has potential to be both effective and present aesthetic quality based on individual characteristics of wood. Further development can integrate a generative tool which would streamline the design and fabrication proces further.

summary A discussion of the outcomes from the use of a game engine based collaborative virtual environment for virtual design studios. By way of introduction the use of a game engine is positioned between the high end visualization capabilities of immersive VR, and the high dimensional accuracy of 3D CAD. Software development, which address problems related to content creation and communication lag, are reported. This is supplemented with a more general discussion of the motivations for design collaboration between architectural schools. We confer with other researchers that lack of engagement is more related to pedagogy, then as a result of technical issues. In conclusion we discuss the potential of game play to enhance virtual design studios in terms of engagement and deliberation

title A METHOD FOR REAL TIME SPATIAL ANALYSIS OF SOUND VIA MODELING IN A CAD ENVIRONMENT, BASED ON ACOUSTICAL MEASUREMENTS
source 14th European Colloquium on Theoretical and Quantitative Geography,September 9-13, 2005, Tomar, Portugal
summary Typical modeling systems for spatial analysis employ data that represent the visual part of a landscape (e.g. relief and morphology), combined with other data about specific attributes (depending on the aims of an application). Thus, in a modeling environment, each place is described by a variety of properties that are not always visible. More of those “hidden” properties require special sensors and/or instruments to be captured and sometimes make their presence evident through human senses, such is sound. The present study takes advantage of wide spread technologies (such as GPS, VHF telecommunications and field sensors) and methodologies that are commonly used in telegeoprocessing – telegeomonitoring in order to simulate an existing acoustic environment. The aim is to acquire real time data about the sound (referenced to a particular area) and manipulate them in a CAD environment with purpose to visualize the sound influence in a specific landscape. Specifically it is proposed a method that transfers spatial data (collected from the field), directly into a modeling system (in the office, or in situ). In sequence the data is processed adequately to feed the modeling system that describes the current sound intensity of a place.

summary Technology has been an obvious solution to the increasing complexity of the built environment. As the number and specificity of use requirements increases, designers, clients and managers tend to segment the overall problem to manageable aspects only tentatively linked to each other. As a result, aspects such as ventilation and lighting tend to rely more on mechanical means than on the affordances of the overall design. Ironically this increases the complexity and opacity of the built environment probably to a greater extent than rules, regulations and requirements. The paper presents a review of available computational methods and techniques that aim at a more coherent approach by supporting integration of (day)lighting into architectural designing. It proposes that the two main courses of further action are the improvement and updating building regulations, and the combination of quantitative knowledge of good, existing daylight designs with advanced simulation-based analyses of early design proposals. Improvements in daylighting design and the integration of daylighting in design solutions depend primarily on design guidance based on the coordinated development and thorough understanding of usable measures such as the Daylight Factor, the Daylight Performance Index and function factors. A major prerequisite to both simulation and design guidance are robust and detailed geometrical 3D models that accommodate both the input and the output of design actions and transactions.

title High Dynamic Range Image (HDRI) Rendering
doi https://doi.org/10.52842/conf.ecaade.2005.349

summary This paper suggests a method known as High Dynamic Range Image (HDRI) to pre-visualise architectural elements in three-dimensional (3D) environment used by Computer Graphic Imaging (CGI) film-makers to integrate 3D models and characters into live action background (special effect). This Intensification Research Priority Area (IRPA) grant project was developed to suggest ways to achieve effective rendering solution and composition of the final output. It will focus on experimental modelling of local cultural elements that provides solutions for radiosity-type effects and dirt shadings. A set of data from an established site (i.e. environment) was captured and represented in High Dynamic Range (HDR) file. This data is integrated with architectural elements (e.g. 3D objects) and then pre-rendered to get the 3D visualisation of the actual environment. Several different exposures were also captured and tested to establish the correct rendering and lighting condition. This earlier result shows that HDRI method provides accurate visualisation and drastically reduces the rendering time without compromising the data (images) with accurate lighting. This paper will demonstrate the process of HDRI, compare the visual impact with ‘radiosity’ technique and other related rendering solutions and present the results, which are useful for architectural animation, simulation and other modelling developments.
