3D model presents step-by-step simplification of a digital reconstruction of a Germanic warrior’s costume (Moskvin, A., Wijnhoven, M.A. and Moskvina, M., 2021. The equipment of a Germanic warrior from the 2nd–4th century AD: Digital reconstructions as a research tool for the behaviour of archaeological costumes. J. Cult. Heritage. 49, 48-58. https://doi.org/10.1016/j.culher.2021.03.003). The simplification (Meshlab software) employed the quadric-based edge collapse algorithm by Garland and Heckbert (1997). The captions above the models present the number of polygons.
