Akrokeramo / Antefix

Digital 3D photogrammetric reconstruction of a traditional Greek akrokeramo (ακροκέραμο / antefix), measuring 12 cm in height. Decorative terracotta antefixes were historically installed along building eaves to seal the joins between roof tiles. They protected the underlying structure from weather damage while serving as a key ornamental architectural feature. This antefix features a classical palmette motif rising above volutes.

Old Windmill of Tolo

A 3D photogrammetric reconstruction of a historical windmill in Tolo, near Nafplio, Greece. Created as a digital twin for cultural heritage preservation, the model was generated using a DJI Air 2S drone. The capture strategy combined multi-altitude orbital flights at oblique angles to document the stone facades, followed by a nadir (top-down) grid pattern to capture the roof geometry and surrounding landscape.
