ON_RTree::Insert I manage to insert elements into an RTree, only one level below the root node.
How can I put them into different levels, as children of upper level leaves?
I tried using
ON_RTree::InsertRect(ON_RTreeBBox* a_rect, ON__INT_PTR a_id, ON_RTreeNode** a_root, int a_level) but this method is inaccessible for me.
Any hint or example will be greatly appreciated.
