Hi,
I am rather puzzled by the following:
select 'BOX3D(0 0 0, 10 10 10)'::box3d &&& 'BOX3D(0 0 90, 10 10
100)'::box3d;
?column?
----------
t
select st_overlaps('BOX3D(0 0 0, 10 10 10)'::box3d, 'BOX3D(0 0 90, 10 10
100)'::box3d);
st_overlaps
-------------
f
select st_intersects('BOX3D(0 0 0, 10 10 10)'::box3d, 'BOX3D(0 0 90, 10
10 100)'::box3d);
st_intersects
---------------
t
(1 row)
Should these queries not all return false (as the boxes do not share any
space)?
Or is it because these functions do not (yet) support 3D (and operate on
the projected 2D primitives)?
If so, I find the documentation for the &&& operator rather confusing...
