WebDec 6, 2024 · However, from the list above I cannot find a suitable concept for my Ring class. Is this way of defining geometry not compatible with Boost Geometry Concept. The reason that I did not use polygon is that the ring here can be defined by three configurations and there is no need to store a detailed externior coordinates. Thanks for your help.
