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.
