That defined column effect does beg my following speculation. We only saw characters materializing upon transporter daises with that laser generated element connecting the upper and lower pads. I wonder how they (the effects crew) would have done the materialization effect for an open environment, no receiving platform like the surface of the planet? Would they have feathered that column? Would they have opted for an ellipsoid or maybe a capsule shape? I mean a crisply defined column would look odd in an open setting.
