Pretty soon, however, it became apparent that with the usual approaches, the visitors could not visuallyperceive thedetailsdue to thesizeof therelief model. Preciselyaccuratepinpointingofpeaks, for example, is fruitless at scales like the one of the Relief von Kärnten. This led to the development of large—sometimes successively shrinking—animations in order to steer the viewing direction of thevisitors. In 2017 and 2018, some special contents were developed, optimized for the newly installed technology. Actually, for each content, two video files supplementing each other are necessary. Therefore, twoindividualfilmshadtobegenerated.
