Boost.Geom purpose is to provide a unified, zero-cost and pretty interface around existing geometric primitive implementations (for now only points and rectangles in 2D and 3D).
Hi Anis, Some quick thoughts: - Thank you for writing some documentation. I found the link unreliable at first but I was able to see the docs eventually. If anyone else failed to connect to the server I suggest trying again. - Perhaps you would like to compare and contrast your library vs. all the other proposals. - As far as I can see, you're supporting homogeneous co-ordinate types (i.e. I can't use a different type for altitude than for latitude/longitude), and you don't provide a way to iterate over all the co-ordinates of a point. I'm not saying this is a good or a bad thing, but it is one of the ways in which the libraries differ. - As I've said before, a variety of conflicting approaches are possible at this "bottom level" of a geometry library. I don't think any one approach is going to make all potential users happy. In order to gain momentum, a library will need to demonstrate that is has worthwhile features at higher levels (algorithms, containers, bindings etc.) If someone were to propose a library full of those higher-level features then it would become popular irrespective of its choice of point concepts. Until then we'll all propose lots of slightly-different "bottom levels" and disagree about which is best. - "Rationale" is spelt with an 'e' when it's a noun in this sense :-) Regards, Phil. P.S. Geometry challenge of the week: a container for lots of very short poly-lines that has less storage overhead than a (sorted) std::vector<std::vector<point>> and provides faster region lookup.
