We have a Vertex object, with a dimension determined at runtime. T 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 Unless my info is outdated.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> box_type; rtree, RTreeParameters, ValueIndexableGetter> rt; Adam
