This is not possible.
Dimension is compile-time trait of any model in the Geometry,
intrinsic or adapted.
Unless my info is outdated.

Ok, I expected that. Is there maybe a way to define the rtree's dimensionality upon creation? So that I can do:

rtree<3, size_t, RTreeParameters, VertexIndexGetter>;

3 beging the dimension.


The only run-time parameters rtree can take are for balancing configuration.

Unless, again, something has changed and rtree can swallow-adapt `Value` type
of any dimension. I'm sure Adam will chime in with further clarifications.

The rtree takes dimension from geometry::dimension of Value's Indexable Geometry in compile-time.

But I don't fully understand the problem. In the code above the dimension 3 is compile-time parameter, not run-time. The equivalent of the code above could therefore be e.g.:

typedef bg::model::box<bg::model::point<3, double, bg::cs::cartesian>> box_type;
rtree<std::pair<box_type, size_t>, RTreeParameters, ValueIndexableGetter> rt;
