title Road hierarchy and speed limits in Brasília/Brazil

summary This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

summary This paper focuses on using oversized display for supporting design communication process between designers and clients. The interactive behaviors are analyzed and testified with a prototype developed in this research. Based on interviews with designers and clients, focus of the communication process in this research is onto developing an immersive environment for exchanging and negotiating the design artifacts. Several immersive virtual environment as well as visualization method (display) is reviewed. Furthermore, three over-sized display projects (ShadowLight, CaveUT and Blue-c) with immersive perception at full-scale or near full-scale design artifacts are studied as the inspiration of this research. Designers identify what kinds of influence they had on the design of client's interior space and to what extent they are aware that they can design and influence their perception. An over-sized display environment with direct manipulation interface is developed for evaluation platform.

title Seat preference in public squares and distribution of the surrounding people: An examination of the validity of using visual simulation
source Motion, E-Motion and Urban Space [Proceedings of the 7th European Architectural Endoscopy Association Conference / ISBN-10: 3-00-019070-8 - ISBN-13: 978-3-00-019070-4], pp. 151-163
summary Public squares are shared by people who use them for various purposes. When people choose seats in a square, they unconsciously evaluate not only the physical characteristics of the space but also the distribution of others already present (Hall, 1966; Sommer, 1969; Whyte, 1988). Knowing the hidden rules of this behaviour will be important in designing squares that remain comfortable even in crowded situations. Most past studies of seat choice preference have reported on statistical tendencies derived from observations of subject behavior in actually existing sites (i.e., Abe, 1997; Imai, 1999; Kawamoto, 2003). However, they provide no clear theoretical model for explaining the basic mechanisms regulating such behaviour. The present study conducts a series of experiments in both real and virtual settings in order to extract quantitative relationships between subjects’ seat preferences and the presence of nearby strangers and to clarify what factors influence their seat choices.

summary Urban plan and architecture require the use of VR systems. We adapted the buildings into a VR system, and then performed a virtual realization in the world’s largest dome at Matsushita Electric Works, Ltd. Walking or flying through life-size space was enabled. We viewed the planned future scenes that featured real size, space composition, and a simulated environment. The construction, the materials and colors of the building were examined. In addition, VR system on PC was applied to city planning and architectural design and a number of novel functions were added to the VR system by plug-in, which assisted and facilitated the design process. The stereoscopic thinking mode in 3-D space can inspire and comprehend more directly the ideas of design, and confirm the intended effects. We accordingly carried out a further study on users operating the VR system to investigate their responses of “like” or “dislike” towards the real time adjustments of design effect at identical viewpoints. Fractals analysis was conducted to demonstrate physically the influence of real time 3-dimentional design and presentation on the psychological trends of subjective judgment. Our findings pave the way for future research on monitoring psychological impacts on observers of VR system during design process.

source CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 269-276
summary Sustainable development issues are currently the driving forces in many building projects. The building envelope is critical for the architectural expression as well as large parts of the environmental performance. This study tries to investigate the advantages of multidimensional computer aided modeling and simulation for a sustainable facade design approach. A first step towards nD modeling for sustainable design is to establish a list of parameter which are used as design criteria: Environmental performance, thermal visual and acoustic comfort. Computer simulation and analysis of different building elements can help to determine the performance according to a set of design parameter. Environmental impacts due to energy consumption are an important parameter but it is believed that comfort criteria need also to be accounted for.

title Sustainable Planning with a Synergetic Collation of Thermal and Dynamic Characteristics of Urban Climate using Map Based Computational 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. 367-382.
summary Since 2006, half of the world’s population lives in cities. In the age of climate change, designing for quality environmental living conditions and sustainability is a topical concern. However, on the one hand, designers and city planners operate with their three dimensional city morphological data such as building shapes and volumes, forms and their spacings, and functional attributes and definition signatures. On the other hand, urban climatologists operate with their numbers and equations, quantities and signals, and normals and anomalies. Traditionally the two camps do not meet. It is a challenge to develop design tools that they can work together. Map based information system based on computational geographic information system (GIS) that is properly structured and represented offers a common language, so to speak, for the two professional groups to work together. Urban climatic map is a spatial and graphical tool with information embedded in defined layers that are collated so that planners and urban climatologists can dialogue over design issues. With various planning and meteorological data coded in defined grid resolutions onto the GIS map system, data can be synergized and collated for various understandings. This papers explains the formulation of Hong Kong’s GIS based Urban Climatic Map as an example of how the map works in practice. Using the map, zonal and district based planning decisions can be made by planners and urban climatologists that lead to new designs and policy changes.

title Computational Assessment of Passive Cooling Methods in Buildings
source Vienna University of Technology; Building Science & Technology
summary Various factors have been contributing to a recent steady increase in buildings’ demands for cooling energy: environmental changes, increased heat gains due to equipment and growing expectations in view of acceptable indoor thermal conditions. Given this context, it’s both environmentally and economically meaningful to develop and implement passive cooling techniques toward the reduction of buildings’ demand for cooling energy. In the present study, we use parametric simulations to compute the relative impact of various passive cooling technologies toward the reduction of overheating risk in residential buildings. The cooling measures under examination are shading, natural ventilation (emphasizing on night time natural ventilation), and the application of phase change materials (PCM). The buildings that are being used for the parametric studies are an apartment and a double-storey single house, both simulated for a Mediterranean climate (Athens, Greece) and middle-European one (Vienna, Austria). The results showed that passive cooling methods can significantly contribute the reduction of overheating in buildings. In particular shading and night time ventilation have been shown to be very effective especially if applied in combination. PCMs on the other hand, showed a limited potential in the reduction of overheating risk, at least under the specific climatic circumstances.

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 Constructing the String Wall - Mapping the Material Process
source Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 326-335
summary The String Wall is the emergent product of a study on technological applications in architecture. Our team attempted to test the limits of the common partition wall construction, challenging the standard notion of the partition screen wall that recedes behind the structures, spaces and objects as a background condition. Such vibrant a partition as the SW becomes the center to the formation of the space it defines. The story of the SW could be described as the organic combination of the bow and the twist. The latent materiality and geometry of the bow and the twist as composite systems that are mined for their structural, tectonic and programmatic potential are tested prior to final construction by 3D printed scaled models. The SW is composed of successive frames that consist of vertical twisted strips of plywood attached to wooden beams. These frames emulate the stud elements of the conventional dry wall partition systems and are manufactured entirely manually. On the other hand, the use of CNC milling machine is employed for the production of the bowed plywood strips that fill in the frame. Three fluctuated curvatures produce strips that are combined rhythmically to produce the striated effect of the SW. The material is manipulated in order to expose its hidden side, the sequence of the multiple layers of the different infilling conditions. The oblique perspective of the SW is achieved through a novel geometric transparency, thus offering constantly changing views to a moving observer. The manipulation of the position of the component bowed and twisted strips explore the application of a see-through condition that escapes the norm and reveals the back to the front in a unique whole. The void of the screen wall becomes ultimately programmatic through the use of light. A sequence of halogen lights situated at the top and bottom of the in-between the wooden strips void create the dumbfounded effect of the SW experience.

summary This report investigates different kinds of Urban Performance in Thames Path, South Bank of Thames River. Urban Performance is defined here as the expression or manifestation of different social groups in the city space regarding the appropriation of a specific place for its spatial practices. The Urban Performances are intrinsic to the cultural expression of the city and revealed through the spatial experience of both performer and spectator. The aim of this paper is to shed light on different kind of urban performances and how are they linked to spatial and syntactic properties of space. This topic is intrinsic in the space syntax theory due its fundamental relation between spatiality and human activity. The research method used were, direct observations by static snapshots and traces (related with human movement) and a survey of potential attractors, active facades and path widths. The results were overlaid with spatial analysis in terms of performers isovists and syntactic analysis through visibility graph. The findings show a strong relation between performers’ use of space and visibility in the urban area, and a high influence of the cultural attractions and public services that works as movement attractors. The discussion is developed through the research findings and theories of spatial experience putting forward varied interpretations related with the research topic and the selected site. The report concludes that the urban performances in Thames path is determined by the human co presence in the space, due to this strategic points chosen along the path by the performers are strongly related with the visual connections in the system. Furthermore, the attractors play an important role shaping the spatial experience and urban character of the studied area.

title Building Information Modeling: Interactive Versioning Experiment
source Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 540-541
summary Interactive Versioning, is the first experiment of an ongoing investigation into the conceptual role of parametric modeling in the design process. In this case, the form is defined by constrained floor-plate relationships. Originally testing methods using numerical values exported to excel, we obtained undesirable results and shifted our focus to the creation of an interactive model; restoring the direct influence of user input. The result is a 10-floor structure that allows the user to tweak point locations along the slab perimeters that in turn have global effect on the overall geometry of the architectural body. We are using four point definition types: reference above, interactive reference, reference below, and independent value. Interactive reference points use referential constraints defined as x and y distances from the global origin, which change on account of user inputs. Reference above points pull (x,y) values from an interactive point above. Reference below points pull (x,y) values from interactive points below. Independent points are unaffected by changes in any of the other points but may also be tweaked to adjust a form. On any given level, there are 2 interactive reference points, 2 reference above points, 2 reference below points, and 4 independent points. Additionally, 2 length constraints link interactive points with reference above points on the same level. This allows for changes to affect the entire structure rather than only the floor plates immediately above and below a given change. The addition of constraints to the floor outlines will yield a variety of formal results and offer the possibility to further control the output.

summary The perception of space, geometry, material and the influence of light is one of the core items of undergraduate courses in architecture. In Bochum we developed and still practise a consequent system of integrating drawing and photography as analytic tools of perception and sketching, descriptive geometry, computer aided design, digital visualisation and animation as synthetic items. The versatile use of digital media in the further studies is of essential significance - especially the synthesis between architectural photography (with all its special features concerning geometrical depicting) and CAD / visualisation / animation. Special emphasis is given to techniques for simulation and immersion such as digital panorama photography, combined with computer-based vr-modelling e.g. vrml as well as using online-cad-modeling and arial photography in processes of citizen participation.

title The Holy Darkness: A Study of Light in Brihadeshvara Hindu Temple, in Tanjore, Tamilnadu, India (1010 AD)
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 425-428
summary The study investigates how religious principles govern the treatment of light/darkness in sacred monument. Specifically, a digitized daylight simulation is used in the analysis of Brihadeshvara Hindu Temple, built in 1010 AD in Tanjore, Tamilnadu, India. This sacred monument, listed as one of UNESCO's World Heritage Sites, is an intriguing case study since the treatment of the 'holy light' in the temple is the treatment of the 'holy darkness'.In spite of the importance given to sun in ancient Hindu scriptures, natural light was used very sparsely in Hindu temples. According to Hindu religious belief, when a worshipper is in the presence of the divine, there should be nothing to distract his/her senses (including vision). Therefore, the innermost sanctum is shrouded in total darkness and the progression into the temple is a ritual movement where the devotee goes through the dynamic experience of the darkening spaces of the temple before reaching the dark sacred chamber (see Fig.1). The dictation of the Hindu faith to create this spiritual procession toward the 'holy darkness' is examined in the historic Brihadeshvara Temple by using Lightscape -- computerized lighting simulation software. To run the program, a 3-D CAD surface model of the temple was created and imported into Lightscape. Then the model was assigned materials and its openings and lighting systems were defined. The simulations were run on four interior horizontal (floor) and vertical (walls) surfaces, along four spaces of the procession in the temple. The simulation targeted three time frames: sunrise, sunset and at high noon on March 21st (the equinox). The location of Tanjore, India was used for light conditions. The Lightscape simulations used the process of radiosity to generate single frame daylight renderings along with light analysis of each surface. A lighting animation was then produced in Quick Time.The results of this analysis demonstrate that the average illumination values for specific surfaces of the temple along the procession sequence correspond to the schematic expectation depicted in Figure 1, i.e., a progressively decreased luminance towards the dark innermost chamber. Furthermore, the simulated values were compared to the Illuminating Engineering Society (IES) standards, which recommend ranges of luminance for specific visual tasks and areas. The comparisons showed that the average luminance in the temple, from the illuminated entrance in the east to the darker chamber in the west, is lower than the IES standards for 'public places with dark surroundings' for 'short temporary visits'. Finally, a morphological analysis of the temple along accepted daylight design guidelines corroborated the previous findings. The multi-method investigation of the relationship of light and darkness, light and objects, and the designated light quality in the Brihadeshvara Temple demonstrates the strong influence of the specific dictum of Hinduism on the light/darkness treatment in the temple. The paper concludes that digitized media such as computerized daylight simulations can examine the significance of light/darkness in sacred monuments as a spiritual experience. This quantitative investigation can augment the qualitative studies in the field of historic sacred architecture.

summary A strong dichotomy exists between the factors of fluctuating natural orders apparent in the river, and the striation of the land by human historical and cultural influence. The installation exists as surface of influence between these forces. The form is informed by parameters of light, vista, material, and process through a method of digitally folding and perforating sheets of steel to enable a self structuring membrane which rises and falls from the plateau edge. A swath of prairie grasses, rising and falling in their own cycle, demarcates this edge. A screen of 15 weathering steel sheets stretches for 63’ across the boundary of the human order and the encroaching erosion of the natural realm. From the initial generation of geometry pairings, well “adapted” pairings are spliced from the parent and “bred” with similarly fit geometries. The fit of these pairs is based on the relationships between the form and the desired criteria of reflection, screening, and framing. To properly combine these pairings, several mutations occur (indicated in red).

title Sensitive Voxel - A reactive tangible surface

summary Haptic and tactile sensations, the active or passive exploration of our built surroundings through our sense of touch, give us a direct feeling and detailed information of space, a sense of architecture (Pallasmaa 2005). This paper presents the prototype of a reactive surface system, which focuses its output on the sense of touch. It explains how touch sensations influence the perception of architecture and discusses potential applications that might arise from such systems in the future. A growing number of projects demonstrate the strong impact of interaction design on the human senses and perception. They offer new ways of sensing and experiencing architectural space. But the majority of these interaction concepts focus on visual and auditory output-effects. The sense of touch is typically used as an input generator, but neglected as as a potential receiver of stimuli. With all the possibilities of sensors and micro-devices available nowadays, there is no longer a technical reason for this. It is possible to explore a much wider range of sense responding projects, to broaden the horizon of sensitive interaction concepts (Bullivant 2006). What if the surfaces of our surroundings can actively change the way it feels to touch them? What if things like walls and furniture get the ability to interactively respond to our touch? What new dimensions of communication and esthetic experience will open up when we conceive of tangibility in this bi-directional way? This paper presents a prototype system aimed at exploring these very questions. The prototype consists of a grid of tangible embedded cells, each one combining three kinds of actuators to produce divergent touch stimuli. All cells can be individually controlled from an interactive computer program. By providing a layering of different combinations and impulse intensities, the grid structure enables altering patterns of actuation. Thus it can be employed to explore a sort of individual touch aesthetic, for which - in order to differentiate it from established types of aesthetic experiences - we have created the term 'Euhaptics' (from the Greek ευ = good and άπτω = touch, finger). The possibility to mix a wide range of actuators leads to blending options of touch stimuli. The sense of touch has an expanded perception- spectrum, which can be exploited by this technically embedded superposition. The juxtaposed arrangement of identical multilayered cell-units offers blending and pattern effects of different touch-stimuli. It reveals an augmented form of interaction with surfaces and interactive material structures. The combination of impulses does not need to be fixed a priori; it can be adjusted during the process of use. Thus the sensation of touch can be made personally unique in its qualities. The application on architectural shapes and surfaces allows the user to feel the sensations in a holistic manner – potentially on the entire body. Hence the various dimensions of touch phenomena on the skin can be explored through empirical investigations by the prototype construction. The prototype system presented in the paper is limited in size and resolution, but its functionality suggests various directions of further development. In architectural applications, this new form of overlay may lead to create augmented environments that let inhabitants experience multimodal touch sensations. By interactively controlling the sensual patterns, such environments could get a unique “touch” for every person that inhabit them. But there may be further applications that go beyond the interactive configuration of comfort, possibly opening up new forms of communication for handicapped people or applications in medical and therapeutic fields (Grunwald 2001). The well-known influence of touch- sensations on human psychological processes and moreover their bodily implications suggest that there is a wide scope of beneficial utilisations yet to be investigated.

summary This study investigates the effectiveness of computer-mediated Engineering Drawing instruction in improving spatial ability namely spatial visualisation and mental rotation. A multi factorial quasi experimental design study was employed involving a cohort of 138, 20 year old average undergraduates. Three interventional treatments were administered, namely Interactive Engineering Drawing Trainer (EDwgT), conventional instruction using printed materials enhanced with digital video clips, and conventional instruction using printed materials only. Using an experimental 3 x 2 x 2 factorial design, the research has found statistical significant improvements in spatial visualisation tasks. There appears to be no improvement in reaction times for Mental Rotation. The authors also have investigated the gender differences and the influence of prior experience of spatial ability.

title The potential of Virtual Environments as contexts for Communication

summary This paper documents a study done considering Virtual Reality (VR) as a spatial representational context which supports communication. It aims to identify whether VR could be considered as a communication medium, a tool that could be used for the successful transmission of information and messages, as well as the future form, content and use of it. That is, how does communication occur in a Virtual Environment (VE), by taking into account its visual properties and spatial parameters and under which conditions communication messages are conducted via VR systems, deriving from the one part (sender) and concluding to the other (receiver). The methods selected for this study involve observation and use of questionnaires at the end of each session. An already existing Internet-based online multi-user virtual environment has been chosen as the context where this survey will be carried out, that is the site Active Worlds, http://www.activeworlds.com, which can be accessed very easy to any computer user, in a desktop form. Firstly, we investigated the time needed, depending on the complexity per case, for a user of the VR application to get acquainted with the system. We were interested to know if the meaning that we would like to communicate had either remained the same through all the time of the experience or had been “modified” in a certain way and if so, for what reason. Another issue that was examined was the way in which the spatial context in a specific VE affects the way communication occurs. The framework of the application may influence the way the person receives a message, for example by making assumptions and references that he would not have made in a different environment- outside VR. After the end of the experience, the user was invited to describe his/ her impressions, with the communication factor being stressed, that is to mean if and at what extent VR can be characterized as a communication medium, as it is mentioned above, even for limited information and messages in general.

title The Impact of Colour on Urban Space Quality
source Motion, E-Motion and Urban Space [Proceedings of the 7th European Architectural Endoscopy Association Conference / ISBN-10: 3-00-019070-8 - ISBN-13: 978-3-00-019070-4], pp. 89-100
summary This paper examines selected aspects of the complex relationship between colour and built environment. Urban space, and the impact of applied colour schemes on the perceived quality of the urban space form core of interest. By studying the exterior colour schemes of existing built environments, it aims at making the attempt to bring more knowledge to urban design by pointing out the conditioning factors of the perceived quality of urban spaces through colour-related indicators. Understanding the conditioning factors of emotional impacts and responses is seen as a potential for improvement through conscious modifications of colour schemes. Such knowledge is essential also for any simulation if it is to be meaningful for studying or visualizing urban spaces. The paper offers first results of on-going mainly experimental research focused on professional colour communication and specification, colour preferences, social attitudes and responses to urban spaces in existing environments. The analyses aim at expanding the knowledge and thus possibilities and tools allowing positive influence on urban spaces and broader townscapes in the process of transformation of historic and more recent urban areas under current development pressures.

title Critical Environmentalism and the Practice of Re-Construction
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 research focuses on the implications and applications of “critical environmentalism” as a quintessential epistemological framework for urban interventions while implementing digital applications that foster collective, round-table approaches to design. Essentially centering the environment (Umwelt) as an encompassing and interconnecting catalyst between multiple disciplines, philosophies, and modes of inquiry and technologies, the framework reciprocally fosters individual and critical identities associated with particular places, belief systems, and their participants as a primary concern. Critical environmentalism promotes a comprehensive, reciprocally unifying epistemological framework that can significantly inform architectural interventions and the tethered use of its technologies in order to foster increased vitality and a certain coinvested attention to the complexities of the greater domain. Grounding the theory in pedagogical practice, this paper documents an approach to urban design and architectural education, implemented as a case-study and design scenario, where divergent perspectives amalgamate into emergent urban configurations, critically rooted in the conditional partialities of place. Digital technologies are incorporated along with analogical methods as tools to integrate multiple perspectives into a single, working plane. Engaging the above framework, the approach fosters a critical (re)construction and on-going, co-vested regeneration of community and the context of place while attempting to dialogically converge multiple urban conditions and modes-of-thought through the co-application of various digital technologies. Critically understanding complex urban situations involves dialogically analyzing, mapping, and modeling a discursive, categorical structure through a common goal and rationale that seeks dialectic synthesis between divergent constructions while forming mutual, catalyzing impetuses between varying facets. In essence, the integration of varying technologies in conjunction, connected to real world scenarios and a guiding epistemic framework cultivates effective cross-pollination of ideas and modes through communicative and participatory interaction. As such it also provides greater ease in crosschecking between a multitude of divergent modes playing upon urban design and community development. Since current digital technologies aid in data collection and the synthesis of information, varying factors can be more easily and collectively identified, analyzed, and then simultaneously used in subsequent design configurations. It inherently fosters the not fully realized potential to collectively overlay or montage complex patterns and thoughts seamlessly and to thus subsequently merge a multitude of corresponding design configurations simultaneously within an ongoing, usable database. As a result, the pedagogical process reveals richly textured sociocultural fabrics and thus produces distinct amplifications in complexity and attentive management of diverse issues, while also generating significant narratives and themes for fostering creative and integrative solutions. As a model for urban community and social development, critical environmentalism is further supported the integrative use of digital technologies as an effective means and management for essential, communicative interchange of knowledge and thus rapprochement between divergent modes-of-thought, promoting critical, productive interaction with others in the (co)constructive processes of our life-space.

title Rosario, Views on the Integral Revitalization of a Cultural Heritage
source SIGraDi 2006 - [10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006
summary This work shows the study of the methods and techniques for the development of a virtual vision VRML 3D included in an "Digitally-integrated knowledge base" with interactive interphases of a significantly revitalized fragment of a central area of the city of Rosario, Province of Santa Fé, Argentina, that includes an emblematic heritage for the Argentineans: the National Monument to the Flag. Digital models that partly allow the development of a hypothesis of integration between the digitized information and information technology - new digital proximity - to the effects of being able to investigate the generation of multimedia database that includes three-dimensional and dynamic models of the mentioned type, in this case, urban, architectonic, and cultural heritage. Different views and research on heritage have been developing. Nevertheless, the use of these new 3D non-immersive technologies and inter-phases are opening a new field of vision and understanding of the subject.
