Delgado-Friedrichs, Olaf2026-01-012026-01-01354020831397835402083100302-9743https://hdl.handle.net/1885/733798979We study barycentric placement of vertices in periodic graphs of dimension 2 or higher. Barycentric placements exist for every connected periodic graph, are unique up to affine transformations, and provide a versatile tool not only in drawing, but also in computation. Example applications include symmetric convex drawing in dimension 2 as well as determining topological types of crystals and computing their ideal symmetry groups.12en200410.1007/978-3-540-24595-7_1727744591286
