Visualization of CH Models: Seeking for Just Visual Quality or Also Informative Content?

Abstract

Detailed and accurate 3D models of Cultural Heritage artifacts are becoming widely available by the diffusion of several new technologies for sem-automatic 3D digitalization. Very dense models require efficient data representations to be rendered in real time (either locally or on the web).

The talk will present current multiresolution approaches for efficient CH data representation and visualization, focusing on both triangle-based and point-based solutions which allow to enconde geometry and color data in a visualization-efficient manner.

But efficiency and visual quality of the visualization are not enough. Another emerging issue is how to enhance the interactive presentation of the artifact with capabilities that allow us to present also all the prossible related meta-information. User are thus looking for technologies able to geo-reference and annotate any type of information on the digital skin of the artwork. Recent efforts in this direction will be presented and discussed.


Roberto ScopignoRoberto Scopigno is a Research Director at ISTI-CNR, an Institute of the Italian National Research Council (CNR). He leads the Visual Computing Lab of ISTI-CNR.

He is currently engaged in research projects concerned with multiresolution data modeling and rendering, 3D scanning, surface reconstruction, scientific visualization and applications to Cultural Heritage. Most of these activities have been funded by EU grants.

He published more than one hundred fifty papers in international refereed journals/conferences and gave invited lectures or courses at several international conferences.

He was Co-Chair of international conferences (Eurographics 1999, Rendering Symposium 2002, WSCG 2004, Geometry Processing Symp. 2004, Eurographics 2008).

Since 2001 he is Co-Editor in Chief of the Computer Graphics Forum Journal. He has been elected member of the Eurographics Executive Committee on 2001, and appointed Chair of the association in 2009.
