When using AR Foundation, is it safe to assume that "down" is in the negative Y direction of the AR coordinate space? Or, to rephrase, Does AR Foundation make an attempt to align its coordinate system with local real-world gravity? If so, how reliably successful is this attempt in plausible real-world usage?
I'm pretty sure every AR device has a gyroscope and can tell exactly where the 'down' direction is. You can't do any motion tracking without it. Your question got me interested if AR Foundation works in zero-G
