    Abstract. The three-dimensional (3D) documentation and surveying of cultural heritage can be carried out following several geomatics techniques such as laser scanning and thermography in order to detect the original 3D shape after applying reverse engineering solutions. In almost all cases, the integration of data collected by different instruments is needed to achieve a successful and comprehensive 3D model of the as-built architectural shape of the historical building. This paper describes the operations carried out by the authors to determine the as-built 3D model of the Escuelas Pias Church, related namely to the dome and circular nave. After the description of the church and historical notes, attention will be driven to the indirect registration results obtained with three different laser scanning software packages, highlighting similarities and differences, and the consequences while generating meshes. The 3D model carried out will then be described and the results of some investigations with regard to the hypotheses about the design of the dome and the origin of the alterations will be presented.</p

    Development of GIS in urban planning agencies in Serbia – experiences of town Planning Institute of Belgrade

    Transition reforming processes in Serbia during past two years created prosperous environment for very complex activities of numerous aid agencies. Owing to some of them the knowledge level about modern concepts and approaches in the field of strategic and urban development is significantly raised in big cities. Especially important was the impact and the effect of building governmental capacities action. During the last year on the highest governmental levels and in some prosperous local governments consciousness of ICT support importance in contemporary urban development management process is higher than ever. Now the problem is lack of capabilities for defining of comprehensive and coordinated action plan, which will initiate the development of primary ICT tools on a city level. On the other hand a large number of local planning agencies started with their own reorganization trying to increase efficiency and effectiveness, and most often they recognized an ICT support as a right way to do it. In many cases local GIS is initiated and basically performed by the planning agency without of local government initial support, but soon after had a acceleration role in further institutional ICT development. In a first place, this paper will provide the oversight of ICT development levels in municipalities of Serbia. Interesting is that public institution ICT development is more rapid in some smaller municipalities than in Belgrade. Therefore, the paper will be more concentrated on presenting the process and problems of ICT development of City of Belgrade public institutions and governmental levels. Under the very difficult conditions Town Planning Institute as a major planning agency in Belgrade is making the big effort to increase work efficiency and effectiveness by using ICT tools. Of course, on an agency organization level the process of ICT implementation is suppressed with new problems. This paper will at the end present the overview of 6 month pilot project of initializing and conceptualizing the IS of planning agency and the results that ICT team succeeded to achieve. As a conclusion the action program for 2004. will be presented

    3D Information Technologies in Cultural Heritage Preservation and Popularisation

    Get PDF
    This Special Issue of the journal Applied Sciences presents recent advances and developments in the use of digital 3D technologies to protect and preserve cultural heritage. While most of the articles focus on aspects of 3D scanning, modeling, and presenting in VR of cultural heritage objects from buildings to small artifacts and clothing, part of the issue is devoted to 3D sound utilization in the cultural heritage field

    Parametric BIM-based Design Review

    Get PDF
    This research addressed the need for a new design review technology and method to express the tangible and intangible qualities of architectural experience of parametric BIM-based design projects. The research produced an innovative presentation tool by which parametric design is presented systematically. Focus groups provided assessments of the tool to reveal the usefulness of a parametric BIM-based design review method. The way in which we visualize architecture affects the way we design and perceive architectural form and performance. Contemporary architectural forms and systems are very complex, yet most architects who use Building Information Modeling (BIM) and generative design methods still embrace the two-dimensional 15th-century Albertian representational methods to express and review design projects. However, architecture cannot be fully perceived through a set of drawings that mediate our perception and evaluation of the built environment. The systematic and conventional approach of traditional architectural representation, in paper-based and slide-based design reviews, is not able to visualize phenomenal experience nor the inherent variation and versioning of parametric models. Pre-recorded walk-throughs with high quality rendering and imaging have been in use for decades, but high verisimilitude interactive walk-throughs are not commonly used in architectural presentations. The new generations of parametric and BIM systems allow for the quick production of variations in design by varying design parameters and their relationships. However, there is a lack of tools capable of conducting design reviews that engage the advantages of parametric and BIM design projects. Given the multitude of possibilities of in-game interface design, game-engines provide an opportunity for the creation of an interactive, parametric, and performance-oriented experience of architectural projects with multi-design options. This research has produced a concept for a dynamic presentation and review tool and method intended to meet the needs of parametric design, performance-based evaluation, and optimization of multi-objective design options. The concept is illustrated and tested using a prototype (Parametric Design Review, or PDR) based upon an interactive gaming environment equipped with a novel user interface that simultaneously engages the parametric framework, object parameters, multi-objective optimized design options and their performances with diagrammatic, perspectival, and orthographic representations. The prototype was presented to representative users in multiple focus group sessions. Focus group discussion data reveal that the proposed PDR interface was perceived to be useful if used for design reviews in both academic and professional practice settings
