https://www.pcgamer.com/the-secret-...s_source=steam&ns_linkname=0&ns_fee=0 The above link is to a PCgamer article about the videogame Warframe, which has a major space-themed content update coming which will include capital ships and space battles (ironically, called Empyrean). One thing they've managed to do with this content is allow the players to freely move throughout the ship while it is in motion and even actively engaging in combat. But as the article explains, this is basically all smoke-and-mirrors. The developers use the same technique used to create portals in the game Portal to project the environment of space onto the ship, which in actuality isn't moving. So from inside the ship, you see the world moving around you in real-time to create the perfect illusion of the ship moving in space, but it's just a projection, and physically leaving the ship causes you to enter that environment normally. Could a similar method be used in Empyrion? Could CVs possibly treat their interior space as a sort of unmoving pocket-instance that is being modified in real-time by what's transpiring in 'actual' space?
