3D visualization of engendering collaborative leadership in the space
2012
The paper focuses on collaborative leadership in education and how to illustrate its engendering process in a three-dimensional space. This complex and fluid process is examined as distributed and pedagogical within a Finnish vocational upper secondary educational organization. As a consequence, the notion of distributed pedagogical leadership is used when collaborative leadership in education is studied. Collaborative leadership is argued to consist of the innermost substance of a professional learning community, as attributes of a group of people working together for specific purposes. Therefore, collaborative leadership naturally involves actors, activities, and context. However, the inn…
Adaptive voice interaction for 3D representation of Cultural Heritage site
2010
In the area of cultural heritage preservation and fruition the development of electronics and information technologies has opened new scenarios of research in the field of survey, representation and communication of Cultural Heritage. The aim is thus to make the fruition of works of art available to as many users as possible by using survey techniques and multimodal interaction. In this paper we propose a multimodal fruition of a virtual representation of a medieval ceiling, built in the XIV century, which covers the “Sala Magna” in the Steri of Palermo. The research deals with the design of an intelligent relational agent which interacts with the user in a natural way. To address this very…
Sharing spatial data with a 3D component as a collaborative and dissemination tool for archaeology: conceptual challenges and technical issues
2018
International audience; Due to INSPIRE directive, various spatial data infrastructure (SDI) were developed to support research activities. In practice, these toolsremain underexploited by researcher for many reasons. First, their use is time-consuming and researchers usually consider that they provide noimmediate benefits. Second, their use is often complex and needs a substantial investment for researchers who have a limited expertise in spatial data. Finally, often based on 2D GIS environment, they do not provide an adequate tool for collaborative research in archaeology. From this experience, an interdisciplinary team designed and developed an SDI based on GeOrchestra, synchronized with …
HIGH QUALITY TEXTURE MAPPING PROCESS AIMED AT THE OPTIMIZATION OF 3D STRUCTURED LIGHT MODELS
2019
Abstract. This article presents the evaluation of a pipeline to develop a high-quality texture mapping implementation which makes it possible to carry out a semantic high-quality 3D textured model. Due to geometric errors such as camera parameters or limited image resolution or varying environmental parameters, the calculation of a surface texture from 2D images could present several color errors. And, sometimes, it needs adjustments to the RGB or lightness information on a defined part of the texture. The texture mapping procedure is composed of mesh parameterization, mesh partitioning, mesh segmentation unwraps, UV map and projection of island, UV layout optimization, mesh packing and mes…
