Can one modify the default Graph3D[]
display to use 3D tubes for
the edges? E.g., how could one modify this simple display
Graph3D[{1 <-> 2, 2 <-> 3, 3 <-> 1}]
to use (possibly thick) tubes or cylinders for the edges?
I would think EdgeStyle->{?}
might accomplish this, but I can't see
how to do it. It appears the vertices are true 3D spheres, so this should
somehow be possible...
Ultimately I would like a "solid" representation of a 3D graph.
Graph3D[{1 <-> 2, 2 <-> 3, 3 <-> 1}, EdgeShapeFunction -> (Tube[#, .02] &)]
? $\endgroup$
