Re: [boost] Geometry and spatial indexes, my opinion

Just to further this point : if we want to do geometry in spherical coordinates, then the point type cannot be homogeneous, especially if we wanted, e.g., to enforce dimensional correctness a la Boost.Units :

cartesianPoint<si::length,si::length,si::length>

vs.

sphericalPoint<si::length,si::radians,si::radians>

You are right, obviously for a spherical coordinate or polar coordinate concept we would use different types. That is one reason why Cartesian point would be a different concept and use different accessors than polar or spherical point. There is no need to have one point concept and set of traits that applies to all 2D, 3D and ND coordinate systems. Luke
