14 | ||
15 | Boost.Tuple tuples with arithmetic elements can be used as | |
16 | points within Boost.Geometry | |
17 | ||
18 | [heading Description] | |
19 | ||
20 | Boost.Tuple fixed sized collections, such as boost::tuple<double, double>, are | |
21 | (optionally) adapted to the Boost.Geometry point concept. | |
22 | ||
23 | Boost.Tuple pairs or triples might have mutually different types, such as a | |
24 | boost::tuple<float, double>. Boost.Geometry reports the first type as its | |
25 | [link geometry.reference.core.coordinate_type coordinate_type]. | |
26 | ||
27 | Boost.Geometry supports Boost.Tuple pairs, triples, quadruples, etc up to | |
28 | tuples with 10 elements (though most algorithms do not support so many | |
29 | dimensions). | |
30 | ||
31 | A tuple can be the point type used by the models linestring, polygon, segment, | |
32 | box, and ring | |
