The conference will be the main event to wrap up the thematic year titled Geometry. Co-organized by the three “Geometry” workgroups of GdR IM and IG-RV (i.e., computational geometry (GT GeoAlg), geometric modeling (GT MG), as well as digital geometry and mathematical morphology (GT GDMM)), this conference stems from a desire to regroup the disparate research communities using geometry as their central subject matter. Indeed, for the first time ever, the three working groups within GdR IM and GdR IG-RV have committed to coordinate and co-locate their annual meetings in order to guarantee the success of the event. The conference aims at gathering a broad spectrum of international researchers interested in the various computational aspects of geometry. Our objectives are to facilitate interactions between the different geometry-centric computing communities, to highlight new trends, and to foster new theoretical or applied developments by assembling a focused event mixing leading experts of geometry and young researchers. The language of the conference will be English.
