 comment Can you see smoothness of the boundary of a convex body from its shadow?
Very nice argument! Presumably this proves the other implication in $d=3$ as well by pulling back the supporting lines from the projection.

Thanks for the reference. I did think that the boundary of the projection would be at least as smooth as the original boundary!
