Thanks for all the great info! This is all very helpful. I think Chris's last point is key - the main problem, as far as field of view and distortion are concerned, is that you're trying to represent a 360 environment wrapping around your eyes in a flat image, typically occupying a small portion of that environment. So, I need a 360 panorama viewed inside of Oculus Rift goggles? Sounds good to me!
@Chris: yes, that formula would be great if you can find it.
Any Maxwell users out there have thoughts about accurate Simulens settings for the human eye?
