> The Binary Space Partitioning trees provided by Apache Commons Math support only Euclidean
geometry in dimensions 1, 2 and 3. However, the designed was done in such a way it could be
applied to other dimensions and geometry types.
> It would be nice to add an implementation on the 1-sphere (i.e. circle) and the 2-sphere
(i.e. common sphere). This would allow applications dealing with geographical coordinates
to define and check points with respect to zones, even containing holes or split in non-connected
parts (lakes, islands ...).
