The first demonstration presented the basic remote collaboration scenario, where 3D models were edited by single user and visualized across multiple displays – ranging from holographic table at KTH in Stockholm, through the 3D UHD displays in PSNC, up to HD and 4K TVs in I2CAT in Barcelona. Participants from all the locations were able to control locally displayed video image of the edited models and comment all the modifications made by the editor. This scenario allowed people located in different places to collaborate on editing advanced 3D models simultaneously.
The second demonstration extended the previous scenario, mainly by the possibility of concurrent editing of 3D models by many participants at the same time. It involved also more participating locations: Poznan, Stockholm, Bristol, Barcelona, Enschede and Kaiserslautern equipped with the high level visualization infrastructure such as 4K and 4K 3D displays, curved 3K display, stereoscopic monitors as well as holographic table. In addition to this the video conferencing connection was established between all the locations. The videoconference connected participants using various technologies such as: H.323, SIP, Skype and Ultragrid. VITRALL software was run on the distributed computing infrastructure located in Poznan.
