title	iSphere:A free-hand 3D modeling interface
source	International Journal of Architectural Computing vol. 4 - no. 1, 19-31
summary	Making 3D models should be an easy and intuitive task like free-hand sketching. This paper presents iSphere, a 24 degree of freedom 3D input device. iSphere is a dodecahedron embedded with 12 capacitive sensors for pulling-out and pressing-in manipulation on 12 control points of 3D geometries. It exhibits a conceptual 3D modeling approach for saving mental loads of low-level commands. Using analog inputs of 3D manipulation, designers are able to have high-level modeling concepts like pushing or pulling 3D surfaces. Our experiment shows that iSphere saved steps in the selection of control points in the review of menus and leading to a clearer focus on what to build instead of how to build it. Novices saved significant time learning 3D manipulation by using iSphere to making conceptual models. However, one tradeoff of the iSphere is its lack of fidelity in its analog input mechanism.

title	Digital Design Pedagogy - Basic Design - CADCAM Space Box Exploration
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 127-130
summary	This proposed paper will highlight the work of a “pre-architecture” graduate student’s work produced in a “Digital Design II” course in Spring 06. This student has a bachelor’s degree in Architectural Technologies and hopes to attend a “professional” degree program in architecture after completing our Master of Science degree program. The student entered our “pre / post-professional” graduate program as a means of learning more about design, technology and architecture. This provided a rare opportunity to do “research” in the area of digital technology in the early formative phases of a new architecture / design students development. The student chose to study “shadows” as a means of design inquiry. The primary focus of the work was the study of various “4” x 4” x 4” “space-cubes.” The student was given various “design” constraints, and “transformative” operations for the study of positive-negative space relationships, light+shadows, and surface as a means of gaining in-sight to form. The CADCAM tools proved to be empowering for the student’s exploration and learning. With the recent emergence of both more user-friendly hardware and software, we are seeing a paradigm shift in design “ideation.” This is attributed to the evolving human-computer-interface (HCI) that now allows a fluidic means of creative design ideation, digital representation and physical making. Computing technology is now infusing early conceptual design ideation and allowing designers, and form, to follow their ideas. The argument will be supported with primary evidence generated in our pedagogy and research that has shown the visualization and representational power of emerging 2D and 3D CADCAM tools. This paper will analyze the basic “digital design” process used by the writer’s student. Architectural form concepts, heretofore, impossible to model and represent, are now possible due to CADCAM. Emerging designers are integrating “digital thinking” in their fundamental conceptualization of form. These creative free-forms are only feasible for translation to tectonic form using digital design-make techniques. CADCAM tools are empowering designers for form exploration and design creativity. Current computing technology is now infusing the creative design process; the computer is becoming a design “partner” with the designer and is changing form and architecture; thus, we are now seeing unprecedented design-make creativity in architecture.

title	Bidirectional Interoperability Between CAD and Energy Performance Simulation Through Virtual Model System Framework
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 232-250
doi	https://doi.org/10.52842/conf.acadia.2006.232
summary	The paper describes a novel approach involving interoperability, data modeling technology, and application of the building information model (BIM) focused on sustainable architecture. They share relationships and multiple experiences that have existed for years but have never have been proven. This interoperability of building performance simulation maps building information and parametric models with energy simulation models, establishing a seamless link between Computer Aided Design (CAD) and energy performance simulation software. During the last four decades, building designers have utilized information and communication technologies to create environmental representations to communicate spatial concepts or designs and to enhance spaces. Most architectural firms still rely on hand labor, drafted drawings, construction documents, specifications, schedules and work plans in traditional means. 3D modeling has been used primarily as a rendering tool, not as the actual representation of the project.With this innovative digitally exchange technology, architects and building designers can visually analyze dynamic building energy performance in response to changes of climate and building parameters. This software interoperability provides full data exchange bidirectional capabilities, which significantly reduces time and effort in energy simulation and data regeneration. Data mapping and exchange are key requirements for building more powerful energy simulations. An effective data model is the bidirectional nucleus of a well-designed relational database, critical in making good choices in selecting design parameters and in gaining and expanding a comprehensive understanding of existing data flows throughout the simulation process, making data systems for simulation more powerful, which has never been done before. Despite the variety of energy simulation applications in the lifecycle of building design and construction projects, there is a need for a system of data integration to allow seamless sharing and bidirectional reuse of data.

title	Hybrid modeling revaluing manual action for 3D modeling
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 392-402
doi	https://doi.org/10.52842/conf.acadia.2006.392
summary	3D modeling software uses conventional interface devices like mouse, keyboard and display allowing the designer to model 3D shapes. Due to the complexity of 3D shape data structures, these programs work through a geometrical system and a graphical user interface to input and output data. However, these elements interfere with the conceptual stage of the design process because the software is always asking to be fed with accurate geometries—something hard to do at the beginning of the process. Furthermore, the interface does not recognize all the advantages and skills of the designer’s bare hands as a powerful modeling tool.This paper presents the evaluation of a hybrid modeling technique for conceptual design. The hybrid modeling approach proposes to use both computer and manual tools for 3D modeling at the beginning of the design process. Using 3D scanning and rapid prototyping techniques, the designer is able to go back and forth between digital and manual mode, thus taking advantage of each one. Starting from physical models, the design is then digitalized in order to be treated with special modeling software. Then, the rapid prototyping physical model becomes a matrix or physical 3D template used to explore design intentions with the hands, allowing the proposal of complex shapes, which is difficult to achieve by 3D modeling software alone.

title	FlexM: Designing a physical construction kit for 3d modeling
source	International Journal of Architectural Computing vol. 4 - no. 2, 27-47
summary	We have designed a hub and strut kit that interfaces to a 3D graphics application. FlexM is a prototype flexible physical interface for manipulating and building 3D geometry. Using the FlexM hub and strut components, designers can build and explore 3D geometry with the ease of a toy and the power of a computer. The hubs transmit the model's topology and geometry to the computer, where the model is rendered on the screen in real time. The paper reports on the iterative development of several versions of the project.

title	Towards a Sketching Tool for Architects: 3D Reconstruction of Polyhedron
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 132-135
doi	https://doi.org/10.52842/conf.ecaade.2006.132
summary	This paper presents a tool for assisting 3D modeling from perspective projections. The proposed system uses a projective geometry engine capable of rebuilding a 3D model from a set of lines and geometric constraints. A dialogue interface assists the user in expressing geometric constraints. The system finds out the relevant geometrical components in the sketch and automatically posts the constraints. The system is limited to rebuilding polyhedrons. If we can deduce, from a perspective sketch of a polyhedron, the planar constraints of the faces and the parallelism constraints of the edges that meet in the same vanishing points, the geometric engine will be able to build a 3D model of the polyhedron.

title	An Approach to 3D Conceptual Modelling
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	This article presents a 3D user interface required by the development of conceptual modeling. This 3D user interface provides a new structure for solving the problems of difficult interface operations and complicated commands due to the application of CAD 2D interface for controlling 3D environment. The 3D user interface integrates the controlling actions of “seeing – moving –seeing” while designers are operating CAD (Schön and Wiggins, 1992). Simple gestures are used to control the operations instead. The interface also provides a spatial positioning method which helps designers to eliminate the commands of converting a coordinate axis. The study aims to discuss the provision of more intuitively interactive control through CAD so as to fulfil the needs of designers. In our practices and experiments, a pair of LED gloves equipped with two CCD cameras for capturing is used to sense the motions of hands and positions in 3D. In addition, circuit design is applied to convert the motions of hands including selecting, browsing, zoom in / zoom out and rotating to LED switches in different colours so as to identify images.

summary	In the process of architecture design, the manufacture of study model acts a procedure of swift transformation from concept to a visible model. Since the era of CAD/CAM approaches, the tool of constructing the model evolves from the traditional physical model to digital model in the mode of the manufacture of study model. The virtual model, which is utilized in the incipient concept discussion by the designer, has become a new intermediary material. However, the virtual model or physical model respectively acts its role that may not be substituted now. TUIS (Tangible User Interfaces) is the intuitional interface system of discussion on striding these two intermediary materials. By the information interchange between the physical model and virtual model, a designer can dedicate to the procedure of design development rather than be restricted to the operation and usage of these interfaces. However, there are many problems existing in applying such a system to the solid geometry model stack. This essay will discuss that a designer explores the incipient design application by manipulating physical model and virtual model.

title	Development of 3D Tactile Models for the Partially Sighted to Facilitate Spatial Orientation
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 366-370
doi	https://doi.org/10.52842/conf.ecaade.2006.366
summary	Lacking or poor provision of comprehensive information about the spatial environment for the purposes of effective orientation is a problem that primarily affects the blind and partially sighted, but it can also cause difficulties for older people with increasing visual impairment. This research project in progress aims to obtain new scientific findings with regard to the basic suitability and required composition of tactile models to facilitate spatial orientation for the blind and partially sighted. Tactile scale models serve as an orientation aid. Their intention is to make it easier for visually impaired people to “experience” selected structural characteristics of the real space, even if in scaled-down form. This experience allows them to experiment with space and to better recognize spatial elements and their interrelationships. It also helps them to better recognize subspaces, possible spatial sequences, as well as decision-making situations in these spaces. These tactile processes are supported by the highly sensitive tactile faculties of people with visual impairment, which are far more finely differentiated than those of sighted people who experience objects without this disability. The amount of available digital model data is constantly growing and would allow for the creation of tactile models.

title	I3-Eye-Cube: interactive intuitive mixed reality interface for virtual architecture
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	This paper introduces a new tangible interface for navigating through immersive virtual Architecture. It replaces the common mouse or glove with a set of tangible cubes. It includes physical architectural floor plans as contextual haptic constraints for the cubes to ensure better object manipulation compared to free space. The position and orientation of the cubes relative to the floor plan is tracked by web cameras and a newly developed program translates this into the 6-dof of the virtual camera generating a 3D view for the immersive projection of virtual architecture. This easy to use tangible interface mixes common 2D dimensional (real) with 3D immersive representation (virtual) of Architecture to overcome the problem of ‘Getting lost in Cyberspace’.

title	An Analysis of the Applications of Rapid Prototyping in Architecture
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	Rapid prototyping (RP) techniques are widely used within the design/manufacturing industry and are well established in manufacturing industry. These digital techniques offer quick and accurate prototypes with relatively low cost when we require exact likeness to a particular scale and detail. 3D modeling of buildings on CAD-systems in the AEC sector is now becoming more popular and becoming widely used practice as the higher efficiency of working with computers is being recognized. However the building of scaled physical representations is still performed manually, which generally requires a high amount of time. Complex post-modernist building forms are more faithfully and easily represented in a solid visualization form, than they could be using traditional model making methods. Using RP within the engineering community has given the users the possibility to communicate and visualize designs with greater ease with the clients and capture any error within the CAD design at an early stage of the project or product lifecycle. In this paper, the application of RP in architecture is reviewed and the possibilities of modeling architectural models are explored. A methodology of developing rapid prototypes with 3D CAD models using methods of solid freeform manufacturing in particular Fused Deposition Modeling (FDM) is presented and compared against traditional model making methods. An economical analysis is presented and discussed using a case study and the potential of applying RP techniques to architectural models is discussed.

title	Optimization in the Balance between the Production Effort of E-learning Tutorials and their related Learning Outcome
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 122-126
summary	This paper provides evidence on the level of media richness that may be cost effective in the development of e-learning tutorials for teaching and learning computer visualization techniques. For such a purpose the author provides an analysis of low-cost / high-impact media rich products, the effort and cost required in their development and the measurement of related learning outcomes. Circa twenty years of R&D of multimedia and hypermedia applications for instruction have demonstrated the benefits of communicating relevant information to learners using engaging media. Based on this evidence, this paper assumes that due to the cognitive style of design students, the instructional packages for learning computer techniques for design visualization that are rich in media content, tend to be more effective. Available visualization technologies make the development of e-learning tutorials feasible and apparently the logical way to implement our instructional packages. However the question in the development of e-learning tutorials becomes a more strategic one when we are called to reach a level of optimization between producing a package with a basic standard, namely; text & still-graphic based tutorials, or a state-of-the-art package that is based on video demonstrations (more than enough?) that can accommodate the students’ learning requirements and also our production costs. The costs include the human resources (instructor, producers, assistants and others) and the material resources (hardware and software, copies, and others) involved in the creation of the e-learning tutorials. The key question is: What is good enough, and what is clearly superfluous? In order to confirm our hypothesis and propose a relevant balance between media richness and learning effectiveness, this paper describes an experiment in the use of two different levels of media richness as used to deliver instructions on the production of computer animations for design visualization. The students recruited for this experiment were fairly familiarized with the use of 3D modeling concepts and software, but had no previous knowledge of the techniques included in the tutorials; in specific; camera animation procedures. The students, separated in two groups, used one of the two methods; then they proceeded to apply their newly acquired skills in the production of an animation without using the help of any external means. The assessment of results was based on the quality of the final product and the students’ performance in the recall of the production procedures. Finally an interview with the students was conducted on their perception of what was accomplished from a metacognitive point of view. The results were processed in order to establish comparisons between the different levels of achievement and the students’ metacognitive assessment of learning. These results have helped us to create a clear set of recommendations for the production of e-learning tutorials and their conditions for implementation. The most beneficial characteristics of the two tested methods in relation to type of information, choice of media, method of information delivery, flexibility of production/editorial tools,! and overall cost of production, will be transferred into the development of a more refined product to be tested at larger scale.

title	Design Informatics: a case based investigation into parametric design scripting and CNC based manufacturing techniques
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	The research paper exemplifies a novel information integrated design technique developed at ONL (Oosterhuis and Lenard), Netherlands, specifically appropriated for manifesting 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 designresearch 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. A pattern of points attained from this intersection: ‘the point cloud’ 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 scriptroutines, iteratively run calculations to generate steel-wire frames, 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 thus enabling timely and effective construction of the conceptualized form.

title	Improving Design Workflow in Architectural Design Applications
source	International Journal of Architectural Computing vol. 4 - no. 4, pp. 1-19
summary	In architectural design software, there is a trend to integrate the whole design process in a single application. Design, 3D modeling, drafting, but also design evaluation and presentation are bundled inside the application. This is especially apparent in applications that adhere to the concept of Building Information Modeling. When we look at the functionality in these applications, however, a disruption of the design process can be encountered, preventing the designer to step back and forth throughout the different design phases or scale levels. Three current architectural design applications are briefly positioned and compared and potential improvements to the workflow are introduced.

doi	https://doi.org/10.52842/conf.ecaade.2006.770
summary	This paper explains the parameters and methodology at the heart of an ongoing research project that seeks to verify whether one can trace back the genesis of any given artefact or work of art by means of computer-aided modeling. In its endeavour our research team Computer Assisted Design Research Group (GRCAO) aims to initiate and propose novel methods of modeling design processes. This approach is exemplified by a case study dealing with rose tracery designs adorning Gothic cathedrals of 12th and 13th Century Île-de-France. A computerized model reenacting their design process was developed along with an interface enabling the translation of the designer’s intentions into a virtual design space. The stated goal of this research project is to evaluate empirically to what extent our modeling strategies can grasp a given artefact as a logical and articulate ensemble. Furthermore, we seek eventually to determine whether this kind of software programme would prove an adequate tool in the development of the architectural designer’s cognitive abilities.

summary	Urban pedestrian studies on navigation have been conducted for developing applications to ease the task of exploring in a virtual environment. As navigation in virtual environments is evidently difficult and as many virtual worlds have been designed to be used by untrained visitors that explore the environment, navigational supports are critically needed. This study is aimed to collect information about the user needs in order to build a model of user preference and produce simulative scenarios that can reveal the navigational patterns related to street design. The study is based on the attention theory for studying people who are socially interacting with street activities and furniture within designated areas. Furthermore, the study attempts to apply agent interface develop a prototype system with space tags. Finally, the system and its applications, and major findings of these applications are reported

doi	https://doi.org/10.52842/conf.ecaade.2006.684
summary	The paper presents ongoing research focusing on the development of digital tools and methodologies for spatial design based on non-Euclidean geometries. It addresses the way sound can be used both conceptually and acoustically in the early stages of the design process, examining digital architectural design and modeling based on three-dimensional sound visualization and the acoustical analysis and evaluation of complex curved surface geometry. The paper describes SoundMatrix, the first part of a digital design tool created by using Max/Msp/Jitter, to assist in the preliminary design of building façades in small-scale urban environments, specifically studying the possibilities of curvature to decrease sound reflection between opposing street façades. Examples from a workshop with the SoundMatrix application illustrate the real-time 3D authoring and sound spatialisation processing currently implemented in the tool.

title	An Intuitive Interface for Building Management and Planning
source	International Journal of Architectural Computing vol. 4 - no. 2, 17-26
summary	Building management and planning professionals utilize database systems for administrative support, but these systems are inadequate for conveying architectural plans. In this article we describe the so-called Virtual Maquette that was developed at the Eindhoven University of Technology for the board of the University. The Virtual Maquette consists of a vertical display for 3D view and information of building stock, and an interactive horizontal display for manipulation of view and information. Interaction is implemented using infrared tracking of devices that are positioned on the desktop with the projected plan view. Through this interface the states of the buildings can be inspected at different periods in history and in the future. The support of multiple devices in a single environment is a technical challenge, but it provides a new interaction method for non-technical persons.
