Isabella’s studiolo is a regular point of reference in the study of Renaissance history and art, yet for centuries it has been accessible only in dispersed pieces and in spaces depopulated of major works and artefacts. Digital technology offers the possibility of creating a “remastered” studiolo, a virtual space in which both visual and acoustic elements may be enhanced with respect to previous attempts at its representation. At the same time, historical uncertainty about numerous details in the arrangement of the objects in this collection requires a high level of flexibility in the digital remix, allowing for the programming of a customisable virtual environment. In anticipation of the project’s full construction and in order to facilitate discussion with potential users about the Virtual Studiolo’s backward design, the authors have developed a concept-demonstration video within the open-source Blender environment (www.blender.org). Among the concerns we aim to address in this phase of the project is how to combine historical accuracy, emotional power, and creative possibilities for users. This case study presents some of the opportunities, constraints and challenges we confronted during the production of our video as we strove within the Blender open environment for a result that will be historically accurate, emotionally compelling, and creatively flexible.

It concerns a cycle of Medieval frescoes, detached from the walls of a monastery in Umbria, Central Italy, altered by numerous and some very recent renovations. At the present, the fragments of the cycle of frescoes are preserved in various museums, mostly in the United States.

Through different case-study projects, carried on at Cineca VisitLab, several Blender key features will be outlined in the present paper.

It can be considered as a versatile mascot of the Etruscan civilization, part of the recent efforts sustained in Italy by different cultural institutions to promote knowledge about the Etruscans. It can also be seen as an example of a methodology in educational video making, based on open source, multiple re-use and sharing of 3D assets opened towards new cross-media applications.

The joint exhibition “The Etruscans and the Afterlife”, hosted by the National Etruscan Museum of Villa Giulia and the Museum of the History of Bologna - Genus Bononiae - presents a strong commitment towards a renewed communicational effort of this kind, merging a traditional display of archaeological findings and spectacular technological applications. The paper presents the three digital applications developed by VisitLab Cineca for the exhibition: a projection show combining 3D architectural mapping, with 10 coordinated projectors, and a holographic projection of the Sarcophagus of the Spouses; the holographic projection of the bronze vase called “Situla della Certosa”; a Computer Graphics short movie, “Ati at the discovery of Veii”.

Feasible solutions for the problem are investigated and two protocols to resolve contention on the shared medium are presented, the single cell and the multiple cell frame based. The performance of the two protocols is evaluated, obtaining indications about the transfer delay introduced by the protocols and the amount of buffering needed at the user side.

When bursty sources are considered, high network efficiency can be obtained by taking advantage of statistical multiplexing. This technique requires to monitor the user behavior, in order to guarantee that the actual traffic parameters do not exceed the maximum values compatible with the required Grade of Service. The paper reviews the major results on the analysis of the control mechanisms. In particular, the three following issues are considered. The Connection Admission Control for both homogeneous and heterogeneous traffic sources is analyzed and the performance of different approaches are compared. The Leaky Bucket mechmism is studied for the Usage Parameter Control and its performance, such as reaction and recovery time, are analyzed. The traffic shaping function is considered in both cases OF availability and non availability of a feedback on the traffic sources. The effectiveness of this functionality is investigated.
