Geometric Modeling: Interoperability and New Challenges (Dagstuhl Seminar 21471)

This report documents the program and the outcomes of Dagstuhl Seminar 21471 "Geometric Modeling: Interoperability and New Challenges". This seminar was initially planned on May 2021, and was delayed due to the pandemic. The seminar took place as a hybrid version with on site and remote participants. It provided a great opportunity for exchanges which, as pointed out by participants, were very appreciated in this period where international scientific interactions have been diminished. This report summarizes the seminar communications, first by providing the abstracts of the talks which present recent results in geometric modeling. Moreover, the scientific exchanges during the seminar provided a great basis for scientific discussions that resulted to the included five reports which highlight the new and future challenges in Geometric Modeling
