Techniques For The Interactive Exploration Of High-Detail 3D Building Reconstruction Using The Example Of Roman Cologne
Abstract
This paper presents the results achieved by an interdisciplinary team of archaeologists, designers, and computer graphics engineers with the aim to virtually reconstruct an interactive high-detail 3D city model of Roman Cologne. We describe a content creation pipeline established to enable a flexible exchange and enhancement of building models, the applied optimization techniques necessary for real-time rendering, and the design of an application framework that enables the coupling of 3D visualizations with additional information in corresponding Adobe Flash widgets. Furthermore, we expose challenges arising by incorporating state-of-the-art visualization techniques, such as cut-away views, non-photorealistic rendering (NPR), and automated label placement. These techniques are used to enhance the interactive 3D environments, to enable for the presentation of interior structures, the precise communication what is hypothetic and what proven knowledge, and the integration of meta information.
