Hello, I'm interested in the tree structure inherent to the gist indexing. I was thinking to retrieve it from order of index. Do you know how I could access it directly?
My use case would be to take advantage of this gist ordering to order 2D points s1 : N1 N2 .. Nn so that for any given t<n, s2 : [N1 Nt] points are an extract of s1 which is well spread (spatially speaking). Ideally I would prefer to use the quadtree index in contrib rather than the Gist R Tree.
