Moreover, rapid advances in digital technologies in recent years offer virtual heritage new direction. This paper introduces our approach toward a networked 3D virtual museum system, especially, how to model, manage, present virtual heritages and furthermore how to use computer network for the share of virtual heritage in the networked virtual environment. This paper first addresses a 3D acquisition and processing technique for virtual heritage modeling and shows some illustrative examples. Then, this paper describes a management of virtual heritage assets that are composed by various rich media. This paper introduces our schemes to present the virtual heritages, which include 3D virtual heritage browser system, CAVE system, and immersive VR theater. Finally, this paper presents the new direction of networked 3D virtual museum of which main idea is remote guide of the virtual heritage using the mixed reality technique.展开更多

This paper reviews the historical context of the political events from 1933 to 1945, the circumstances for the betrayal, and arrest of the group in hiding, the saving of Anne Frank＇s diary and its publication after her death at the Bergen-Belsen concentration camp in March 1945. Further, the paper reconstructs the beginnings of the heritage site as a small museum at 263 Prinsengracht in 1960 as well as the management issues and capacity problems that led to a larger museum complex including an educational center in 1999. During the years of 2007-2010, when the annual visitation of the museum surpassed one million, the Anne Frank House decided to introduce a high quality 3D version of the Secret Annex on the Intemet. In the final part of the paper, trends in museum management and the more frequent uses of a digital documentation of heritages sites are reviewed.展开更多

Passing from a general review to the illustration of the background project, named MUSINT, the authors underline the objectives. The present case study primarily aims to share information about valuable archaeological collections which have little visibility. To enhance the project＇s contents, which include a whole set of different artifacts, the authors have reproduced high resolution, faithful and measurable digital models on one side, and on the other, lower resolution and geometrically simplified models are yet completed and very close to reality. The former are meant to implement a scholars＇ archive for further scientific activity. The latter to provide content for virtual exhibitions on the Web or on stand-alone interfaces situated in the actual physical museum spaces. The data acquisition and post-processing methods which have been tested and chosen are here briefly described. Hence, the authors then give an account of the most recurrent problematic issues of the established work-flow and how they should be solved. Touched instances are the delicate placing of the artifacts, which must be digitized, in relation to the triangulation-based laser scanner＇s functionality, the refining operations in order to build a coherent single polygon mesh, the most effective ways to deal with unavoidable missing parts or defected textures in the generated model and so on.展开更多
