3D reconstruction of Burg Alzenau (Spessart, Bavaria), representing the castle's hypothetical state c. 1555–1634. Produced using close-range photogrammetry (Agisoft Metashape) and manual modelling (Blender) as part of a master's thesis applying the de Kramer typology (2020). Colour coding indicates degree of evidence: 🔵 Blue — Relict (direct physical evidence) 🟡 Yellow — Interpolated (partial evidence + inference) 🔴 Red — Extrapolated (typological norm) 🩷 Pink — Speculative (informed hypothesis) Full paradata documentation, archival sources, and dataset available open access on Zenodo (CC BY 4.0):
