This paper explores the potential of using Microsoft's Kinect to create a low-cost and portable system to virtually navigate, through a prototype 3D GIS, the digitally reconstructed ancient Maya city and UNESCO World Heritage Site of Copan in Honduras. The 3D GIS, named QueryArch3D, was developed as part of the MayaArch3D project (http://mayaarch3d.unm.edu), which explores the possibilities of integrating...
Reconstruction of ancient artifacts from fragments found at archaeological sites, is a tedious task that requires many hours of work from the archaeologist and restoration personnel. In this paper, we introduce an automatic technique for fragment reconstruction based on projective GPU depth maps that takes, as input data, a set of geometric representations of broken flat fragments, and finds the best...
Archaeological surveying undoubtedly belongs with the fields of research most elaborated in this domain of study. This is inevitably linked both to the scale of the problems tackled and — in more strictly ‘physical’ terms — to the fact that this operation is closely and indissolubly related to the continuous evolution of the archaeological excavation. The expectations related to archaeological surveying...
Experience-based exhibitions are effective in helping people understand the mechanism, functions, and background information on the exhibits. Visitors, however, do not necessarily experience the exhibits in the expected way. A museum cannot prepare explainers for all the exhibits, and the information on description panels is sometimes not enough. In this paper, we propose a system that records and...
The ceiling of the gallery frescoed in the sixteenth century for the Riccardi family by Luca Giordano was reproduced full-size through a high-resolution digital mapping converted into a virtual image with anamorphic processing that allowed it to be projected on the floor. In this way, visitors were able to “walk” on the painting reproduced on the floor, experiencing a physical contact with the work,...
Many applications for generating and authoring 3D content are dependent on interaction and visualization on a 2D screen. There have been various applications using 3D interaction to overcome the limited interaction in 2 dimensional space. Those applications, however, require special hardware [13] for interaction or marker-based techniques for scene recognition and tracking. Both approaches make the...
November 2011 saw the opening of the exhibition “Archeovirtual” organized by CNR ITABC — Virtual Heritage Lab — and V-MusT Network of Excellence, in Paestum, Italy, under the general direction of BMTA1. The event, that was part of a wider European project focus on virtual museums, turned to be a great opportunity to show many different projects, applications and installations about Virtual Reality...
Information entities can often be described from many different points of view. In the digital domain, a multimedia environment is fit to the goal of describing, as well as a multimodal framework is fit to the goal of enjoying those information entities which are rich in heterogeneous facets. The proposed approach can be applied to all the fields where symbolic, textual, graphical, audio and video...
This paper describes our study on skillful object manipulation in virtual environments. The study deals with juggling balls and aims to implement a virtual environment in which juggling operations similar to those in the real world are possible. The juggling task requires precise ball handling and quick hand motion and the virtual environment must respond to the user accurately and quickly. This paper...
CINECA and Bologna City Council are undertaking the creation of a framework that can both collect and share 3D models and all the useful knowledge to create them. A repository, dedicated to the area of Bologna and with geo and time referenced data among others, would handle the already existing historical, archaeological, artistic and architectural 3D models, making them available to the community...
The paper presented describes the final step of four years survey activities on Milan Cathedral. The main aim of the job was to survey and model the big spire to support restoration works that had just started. The last stage was to transform the great model into a 3D WEB BIM to help manage and organize restoration works.
The paper presents a method of modelling and dynamic multi-platform presentation of interactive 3D web content. The method is based on a multi-platform extension of previously developed Flex-VR approach, which provides a rich data model for 3D content, covering both the geometrical and the behavioural aspects. Based on the model, interactive 3D presentations can be dynamically generated in different...
A basic limit of most Virtual Reality (VR) applications reproducing cultural sites developed by the scientific community is that they often fail to fire up the attention and the involvement of the public. Starting from our experience in this domain, we would like to discuss some of the fundamental concepts about the potentiality of virtual ecosystems and to propose new natural interaction interfaces...
In the field of oral rehabilitation, innovative methodologies based on the combined use of 3D imaging technologies and computer-guided approaches, have been developed with the aim at defining reliable tools for the virtual preoperative assessment of implant placement. The accurate and reliable transfer of the virtual planning into the surgical field represents the main challenge for modern implantology...
This paper presents the development of an application created to assist the teaching of dental structures, generate rich content information and different manners of interaction. An ontology was created to provide semantics informations for virtual models. We also used two devices gesture-based interaction: Kinect and Wii Remote. It was developed a system which use intuitive interaction, and it is...
This paper outlines a program (ISEE) to visualise interactive 3D environments and access information through the Web. ISEE had been prototyped as content management tool with Internet Explorer since 2008 and currently supports the major browsers. Its database of information is stored in MySQL. The basic idea of the software is to enable information retrieval by simply looking inside a 3D environment,...
In this paper we present a surgical application based on virtual reality called AYRA. AYRA allows surgeons training, planning and optimization of surgical procedures. AYRA was developed under a research, development and innovation project financed by the Andalusia Department of Health called VirSSPA. AYRA is very important for the health organization since the surgeons can be trained and helped by...
Valuable documents are included in the corpus of information, documentation, digital contents produced in the course of projects aimed at studying and defining a preservation (and possibly restoration) plan for a significant piece of cultural heritage. These documents could be exploited to effectively further valorize the cultural heritage and support its fruition by a wide audience of potential users...
The aim of "Matera Città Narrata" (Matera: Tales of a City) project is the creation of a digital platform able to support the public before and during the visit of Matera (Unesco World Heritage since 1993), through the access to cultural contents while attending places, sites, itineraries. It does not consist in a descriptive traditional guide inspecting monuments and mentioning who made...
