They spontaneously appropriated its operation

Visitors to Cluny will be frustrated. To enable them to collect the possible the Abbey Cluny Paritech destroyed in almost all after the revolution, the Central monuments allow arts pour leur permettre de percevoir le Paritech Cluny possible l' abbatiale détruite en quasi-totalité après la Révolution, le Centre des monuments leur permettre arts elements virtual of the past. In what remains of the large transept, they fall now stop before a screen mounted on a base that rotates horizontally and vertically. They spontaneously appropriated its operation. "Focusing screen, they have the feeling of actually being inside the Church, because they view them full-size the nave and the forest of today missing pillars", explains Christian father, lecturer at the school of arts and crafts, responsible for this project called "Gunzo", in honour of the monk responsible for the building of the great Abbey Church. A second terminal installed at the top of a tower from the 12th century to rebuild the Abbey in the Cluniac landscape. Two others are under development. They will be installed in May 2010, to mark the 1.100e anniversary of the birth of the Cluniac order, a small transept, the other in the Park, offering a view of the apse and the chancel of the Church.

Real light

To digitally rebuild the building disappeared, remnants that remain have been scanned in 3D. "These remains represent that 8 of the former Abbey, but without them it would have been impossible to calibrate digital model in the existing site with the precision that we wanted to get," explains Christian Père. The various elements of the Abbey were then designed by extrapolation in CAD. A reconstruction validated by historians. "Beyond technical innovation, the great merit of the project is to work as closely together of different scientific practices and culture specialists," noted Patrice Callet, specialist of the synthesis of images of the Central School of Paris. In-the-art in this area, the school of arts and crafts of Cluny inaugurate on 16 November a virtual immersion room specially designed for the representation in 3D buildings.

Stored on a computer hidden in a technical Board, virtual images of the Abbey are sent on the screens and adjusted the angular position of the Terminal. "Give the visitor the impression that he really sees the Abbey, to adapt the light of the image projected on the screen at the true luminosity of the site." "This allows permanent interaction between reality and virtuality, which is the essence of augmented reality," stresses Christian Père. A sensor installed on the roof of the school filming the sky to capture the position of the Sun and analyse the brightness. A trick allows to inform ongoing virtual image with real light: the project engineers have pre-calculated all images taking into account all possible brightness according to the seasons and the hours of the day. The brightness that detects the sensor can be assigned to images instantly. To give the sensation that the Abbey Church is in the present, a camera filmed and passes constantly passers-by or vehicles that move to the screen. The effect is striking! The abbeys of Romainmôtier, Switzerland, and of Hirsau, in Germany, also decided to use augmented reality to regain their coats of arms.
