The DACORD functional system, developed within the scope of collaboration between the University of Burgundy (Dijon) and Masaryk University (Brno), orients and draws archaeological pottery, based on 3D model geometry, using modern mathematical, graphical, optimization methods. The orientation workflow combines existing approaches (normal vectors, horizontal / vertical sections, etc.) with new methods, to segment fragments (external and internal surfaces), and to erase parts that provide no information about the rotational axis (fractures, plastic decoration, etc.). Archaeological illustrations adapted to most norms and standards of pottery drawings can then be produced from these correctly oriented models. All pottery orientation and drawing methods are implemented in DACORD software, developed in R.
Various 3D models of archaeological sites, monuments, rock-arts and artefacts from Mongolia, France and Czech republic are available on Sketchfab webpages.
