They are, therefore, still the preferred surface encoding of many heritage projects that want to leverage digital surface approximations to further heritage insights (and not just use them as mere eyecatchers). Other than their full 3D counterparts and in contrast to the focus of most academic research, 2.5D raster surfaces are ideally suited for visualising and analysing sizeable, detailed surfaces. Although this article provides image acquisition and processing specifics, it aims to assess which image-based modelling workflow can achieve the most detailed, noise-free, two-and-a-half dimensional (2.5D) raster surface of this mural painting. Stephen's Cathedral, the three-dimensional (3D) geometry of the entire painted surface was digitised in minuscule detail using thousands of overlapping photographs. To answer specific research questions about a 16th-century mural painting located in the Bischofstor of Vienna's St. , Markus Santner and Immo Trinks OrganizationĪbstract The surface of most heritage objects holds important clues about their creation.
