WebThe query framework is flexible and powerful; one can use any number of predicates to help the algorithm select appropriate items in the index. An R-Tree holds a value type, which can be just a “model” type from Geometry, such as Box (which is all I use for this demo). A value can also be a std::pair or a std::tuple.

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.
