The free function union calculates the spatial set theoretic union of two geometries.
- Template Parameters:
-
| Geometry1 | Any type fulfilling a Geometry Concept |
| Geometry2 | Any type fulfilling a Geometry Concept |
| Collection | output collection, either a multi-geometry, or a std::vector<Geometry> / std::deque<Geometry> etc |
- Parameters:
-
| geometry1 | A model of the specified concept |
| geometry2 | A model of the specified concept |
| output_collection | the output collection |
- Note:
- Called union_ because union is a reserved word.
- Examples:
