The imagery is madevisible on iPad screens that visitors use as mobile viewing windows to exploreevery feature of the actual cave within the perimeter of the HK Art Fair booth.

The presentation isan innovative augmented reality installation whereby the paintings andsculptures of the caves are rendered virtually with the architecture of thebooth, which shares similar dimensions to those of Cave 220 at Dunhuang in thegrottoes.

The highly originaltechnical rendering of “Pure Land” is made possible by a number of infraredcameras in the booth that track the position and orientation of the iPads.Computers then create the appropriate views of the actual Dunhuang cave, whichare sent to the iPads via a wi-fi connection

The walls of the HKArt Fair booth are covered with full-scale photographic prints that show laserscans of the architecture of Cave 220 made by the Dunhuang Academy. These alsoprovide a structural and aesthetic alignment between the space of the booth andthat of the cave.

The original laserscans have been converted into a 3D polygonal mesh, which form the virtualsurface structure onto which the Dunhuang Academy’s high-resolution photographsof the Cave 220 paintings and sculptures are rendered. This composite 3Drepresentation is what becomes viewable on the iPad screens.

The presentation atthe HK Art Fair 2012 is a world’s first, showing the future of mobile media asa means of virtually embodying 1:1 scale cultural heritage experiences. Itcreates a space for the conjunction between real and virtual formations thatgives transacted aesthetic expression to Dunhuang’s treasury of wall paintingsand sculptures. It has been produced at the CityU Centre for Applied Computingand Interactive Media (ACIM).
