| [section:boost_tuple Boost.Tuple] |
| |
| Boost.Tuple tuples with arithmetic elements can be used as |
| points within Boost.Geometry |
| |
| [heading Description] |
| |
| Boost.Tuple fixed sized collections, such as boost::tuple<double, double>, are |
| (optionally) adapted to the Boost.Geometry point concept. |
| |
| Boost.Tuple pairs or triples might have mutually different types, such as a |
| boost::tuple<float, double>. Boost.Geometry reports the first type as its |
| [link geometry.reference.core.coordinate_type coordinate_type]. |
| |
| Boost.Geometry supports Boost.Tuple pairs, triples, quadruples, etc up to |
| tuples with 10 elements (though most algorithms do not support so many |
| dimensions). |
| |
| A tuple can be the point type used by the models linestring, polygon, segment, |
| box, and ring |
