#3056: Confusing results from ST_3DDistance
---------------------+------------------------------------------------------
Reporter: strk | Owner: pramsey
Type: defect | Status: new
Priority: medium | Milestone: PostGIS 2.2.0
Component: postgis | Version: 2.1.x
Keywords: |
---------------------+------------------------------------------------------
If we adopt the semantic of "missing dimensions are filling"
(#3045) then ST_3DDistance(3d,2d) should always compute the 2d distance,
rather than arbitrarily set the Z value of the 2d operand to 0.
