Quick and dirty Sample lighting:
Good study. I'm glad we're having this discussion on the bridge dome. It's something I've always wondered about and have been too afraid to ask. I've seen many "versions" of what the bridge ceiling would look like. Some have gone the transparent route to fit in line with The Cage/The Menagerie,
others have taken a more TMP route. I, personally, have always gone with the flatter, wider, lit dome that seems fitting for how much light is spilled around the bridge. I think it's these interpretations that give a needed variation to each of the digital Bridge recreations I've seen in my lifetime. One of those Star Trek
mysteries that seems best if it remains a question in our minds and therefore a topic for discussion.
