3D model presents step-by-step simplification of a scan of a traditional Russian costume by Kuzmichev (IVSPU, 2023c. Rediscovering Russia: the cotton path - from fiber to clothing. https://office.ivgpu.com/projects/science/506). 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.
