DEVELOPMENT OF A VIRTUAL MUSEUM INCLUDING A 4D PRESENTATION OF BUILDING HISTORY IN VIRTUAL REALITY

In the last two decades the definition of the term “virtual museum” changed due to rapid technological developments. Using today’s available 3D technologies a virtual museum is no longer just a presentation of collections on the Internet or a virtual tour of an exhibition using panoramic photography. On one hand, a virtual museum should enhance a museum visitor's experience by providing access to additional materials for review and knowledge deepening either before or after the real visit. On the other hand, a virtual museum should also be used as teaching material in the context of museum education. The laboratory for Photogrammetry & Laser Scanning of the HafenCity University Hamburg has developed a virtual museum (VM) of the museum “Alt-Segeberger Bürgerhaus”, a historic town house. The VM offers two options for visitors wishing to explore the museum without travelling to the city of Bad Segeberg, Schleswig-Holstein, Germany. Option a, an interactive computer-based, tour for visitors to explore the exhibition and to collect information of interest or option b, to immerse into virtual reality in 3D with the HTC Vive Virtual Reality System

Chiral molybdenum(0) and tungsten(0) carbonyl diimine complexes

The chiral diimine ligand C5H4N-2-C(C6H5)=N{(1S,2S)-C5H8-2-OCH2C6H5)} (1) was prepared via the reaction of 2-benzoyl pyridine and (1S,2S)-(+)-2-benzyloxycyclopentylamine. 1 (=L) reacts with M(CO)(6) in toluene to give the respective metal(0) complexes [M(CO)(4)(L-kappa N,N')] (M = Mo (2) and W(3)). 1-3 were fully characterized by elemental analyses, 1R, multinuclear NMR spectroscopy and MS. The complexes 2 and 3 are isostructural and crystallize in the chiral hexagonal space group P3(1) with three molecules in the unit cell. (C) 2008 Elsevier Ltd. All rights reserved

SEGEBERG 1600 – RECONSTRUCTING A HISTORIC TOWN FOR VIRTUAL REALITY VISUALISATION AS AN IMMERSIVE EXPERIENCE

The 3D reconstruction of historic buildings and cities offers an opportunity to experience the history of relevant objects and their development over the centuries. Digital visualisations of such historic objects allow for a more natural view of history as well as showing information that is not possible in a real world setting. New presentation forms, such as the virtual reality (VR) system HTC Vive, can be used to disseminate information in another dimension and simplify the access by changing the user’s viewpoint from a listener and viewer into being an integrated part of an interactive situation. In general, this approach is a combination of education and entertainment, also known as “edutainment” or “gamification”, a term used in the education sector as describing where motivation to learn is encouraged through adding a competitive element. It is thus a step away from simple consumption of information towards experiencing information and a more literal interpretation of “living history”. In this contribution, we present the development of a 3D reconstruction of the two towns Segeberg and Gieschenhagen (today: Bad Segeberg) in Schleswig-Holstein, Germany in the Early Modern Age around 1600. The historic landscape and its conversion from a reconstructed virtual town model into an interactive VR application is also described. The reconstruction is based on a recent digital terrain model as well as survey data of surviving buildings, historic visual information based on historic drawings and written accounts from that era. All datasets are combined to a single walkable virtual world that spans approximately 3 km²
