Invited Article Linking structure, texture and context in a visualization of historical drawings by Frederick William IV (1795-1861) Katrin Glinka, Christopher Pietsch, Carsten Dilba, Marian Dörk Abstract: In this article we present a case study on digital representation of the art historical research and metadata brought together for a scientific collection catalogue by the Prussian Palaces and Gardens Foundation Berlin-Brandenburg. The resulting interface aims at linking the structure and texture of a collection of drawings by Frederick William IV of Prussia (1795–1861) with additional contextual information. The article describes the context of the larger research project and presents the resulting visualization and interaction techniques specifically designed for dynamic exploration along time and subjects. Keywords: information visualization, metadata, zoomable user interface, direct visualization, case study, inventory catalogue, digital art history Link: https://uclab.fh-potsdam.de/fw4/en 1 and ensure conservation3.
