Mathematically, the (vector) sum A+B of two sets A and B is defined as 
the set of all points x=a+b with a in A and b in B.
A+B = { x : x=a+b, a in A and b in B }.

A "simple" example is the sum of two convex polyhedra (cube, 
tetrahedron, octahedron, etc.) which is again a polyhedron.

Another example is the sum of a set A with a sphere of radius r, 
centered at <0,0,0>, which gives the set of all points "within distance 
r of A". This would give a nice "rounding effect".

I hope this gives a little idea of what i had in mind.
