[postgis-users] 3d buffering

[Sufficool, Stanley]

I recall asking this question before (with tongue in cheek).
 
Point --> Sphere
Line --> Sausage
Polygon --> Extrusion
 
I imagine if you were to look at this practically, each point would be
buffered to a sphere for a given geometry and then tangent planes would
be added. The inner facing surfaces of the spheroids would then be
removed.
 
I think this is a function of a rendering engine, not of a spatial
database.
