Actually the projection is correct, but the camera is not exactly at the center of projection, so it appears that the lines are bent across the monitor edges. However, if you place your head at the exact center of projection, they look correct. I'm actually doing three separate projections, instead of just stretching one image across three displays. The GoPro field of view was not able to capture everything, so I had to pull it back a bit, and so its not perfect. A spherical camera would have done a better job here.

Man I'd love to try this. I played a lot of Flight Simulator 5.1 back in the day, which actually included the whole Flight Simulator 4 world as well - you could choose to load it in from one of the menus. The untextured terrain was so much harder to read though!
