3D VIRTUAL CH INTERACTIVE INFORMATION SYSTEMS FOR A SMART WEB BROWSING EXPERIENCE FOR DESKTOP PCS AND MOBILE DEVICES
2018
Abstract. Recently, the diffusion of knowledge on Cultural Heritage (CH) has become an element of primary importance for its valorization. At the same time, the diffusion of surveys based on UAV Unmanned Aerial Vehicles (UAV) technologies and new methods of photogrammetric reconstruction have opened new possibilities for 3D CH representation. Furthermore the recent development of faster and more stable internet connections leads people to increase the use of mobile devices. In the light of all this, the importance of the development of Virtual Reality (VR) environments applied to CH is strategic for the diffusion of knowledge in a smart solution. In particular, the present work shows how, s…
Processing of 3D Models for Networking of CH in Geomatics
2020
In recent times the possibility of reconstruction of complex 3D Cultural Heritage (CH) environments has opened new scenarios for touristic and scientific aims. The different needs for networking or conservation purposes of CH lead to study proper structuring of 3D models. In light of this, a scientific approach has been developed in order to test the networking capabilities, comparing different loading configurations of 3D environments with multiple combinations of 3D models inside them, considering different solutions. This experimentation has been based on WebGL-HTML5 technologies and allowed to discover the true balance between performances of proposed system, the quality of visualizatio…
Towards Digital Twinning on the Web: Heterogeneous 3D Data Fusion Based on Open-Source Structure
2023
Recent advances in Computer Science and the spread of internet connection have allowed specialists to virtualize complex environments on the web and offer further information with realistic exploration experiences. At the same time, the fruition of complex geospatial datasets (point clouds, Building Information Modelling (BIM) models, 2D and 3D models) on the web is still a challenge, because usually it involves the usage of different proprietary software solutions, and the input data need further simplification for computational effort reduction. Moreover, integrating geospatial datasets acquired in different ways with various sensors remains a challenge. An interesting question, in that r…
GLOBE BASED 3D GIS SOLUTIONS FOR VIRTUAL HERITAGE
2018
Abstract. During the last years, many solutions have been proposed for 3D Virtual Heritage representations. Recently, also new technologies for online gaming evolved, based on javascript libraries (WebGL), used to create and publish virtual interactive environments. They are based on recent Web browser’s functionalities, surpassing some limitations of VRML technologies. On the side of geospatial information, technology has evolved from desktop GIS to 2D WebGIS and globe applications. The use of globe applications is, today, very diffused due to its immediate and at the same time impressive representation of the earth surface and territories. These technologies have been, also, applied to Vi…
Development of a Virtual CH Path on WEB: Integration of a GIS, VR, and Other Multimedia Data
2021
Recent advances in computer science allowed people to explore new possibilities for the fruition of CH all around the world. The development of Geographic Information Systems (GIS) in the field of territorial systems and the evolution of Virtual Reality (VR) solutions opened new scenarios for the valorization of cultural goods. At the same time, recent advances in digital photogrammetry and 3D interactive navigation models on WEB-based on WebGL technologies offered new opportunities of digital fruition of CH. Considering this panorama, the presented work shows how the integration of these technologies gives a precious added value to the virtual fruition of CH. In particular, it has been con…
Definition of a Workflow for Web Browsing of 3D Models in Archaeology
2016
The Cultural Heritage (CH) is a fundamental element of promotion of territories and of tourism development. Publishing 3D models of archaeological sites and their three-dimensional reconstruction on the Web is one of the best ways to spread their knowledge. However, many recent scientific researches in this field have highlighted the limitations and difficulties related to the networking of interactive 3D models. The main difficulties are related to the complexity and the size of models, which influence the access speed, and the cost of software and hardware needed for the publication on the WEB. In light of this background, this article describes the further advances of research activities…
Sharing on web 3D models of ancient theatres. A methodological workflow
2016
Abstract. In the last few years, the need to share on the Web the knowledge of Cultural Heritage (CH) through navigable 3D models has increased. This need requires the availability of Web-based virtual reality systems and 3D WEBGIS. In order to make the information available to all stakeholders, these instruments should be powerful and at the same time very user-friendly. However, research and experiments carried out so far show that a standardized methodology doesn’t exist. All this is due both to complexity and dimensions of geometric models to be published, on the one hand, and to excessive costs of hardware and software tools, on the other. In light of this background, the paper describ…
3D DATA INTEGRATION FOR WEB BASED OPEN SOURCE WebGL INTERACTIVE VISUALISATION
2022
Abstract. Recent advances in open-source geospatial technologies in WebGIS allowed the visualization of a 3D complex environment on the web, exploiting realistic Globe reproduction of the real territorial asset. At the same time, in the field of gaming technologies, the new possibilities offered by open-source WebGL JavaScript libraries allowed the creation of Virtual Reality navigation models on the web. The integration between 3D GIS globe navigation models and VR environment navigation is a solution that offers a further level of detail in web navigation, exploiting the capabilities of web browsers in the best way. This research further contributes to this field, showing a workflow to in…
HTML5 monialustaisessa pelikehityksessä : kaksiulotteiset minipelit Phaser-pelimoottorilla
2015
Mobiililaitteiden yleistyessä videopelien pelaamiseen on tarve pelien helpommalle kehitykselle ja levitykselle kasvanut. HTML5 on avoin web-standardi, joka mahdollistaa monialustaisen multimediasisällön näyttämisen suoraan Internet-selaimissa. HTML5:n avulla voikin olla mahdollista luoda pelejä, jotka eivät kärsi natiiviohjelmien tavoin yhteensopivuus- tai asennusongelmista. On kuitenkin oletettavaa, ettei HTML5 ja siihen sidoksissa olevat tekniikat tai sitä tukevat Internet-selaimet ole vielä täysin valmiita kaikkiin web-teknologian asettamiin haasteisiin, mutta sitä voitaneen kaikesta huolimatta jo käyttää täysin pelattavien ajanvietepelien toteuttamiseen. Tämä tutkielma tutkii monialusta…
