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.
Cheers,
Rémi-C

the point of this.
