This video was taken with a pair of full circular fisheye lens on Gopro. I have to wrap the fisheye to equirectangular format in PTGUI before it can be displayed well in VRPlayer with the dome-projection mode. Anyway adding a cockpit image to fill the 2nd half sounds an interesting idea, so please enjoy the movie in the sphere mode as usual pls view the youtube in 4K mode, or download the 2560p version here
p.s. We tried many fish lens on the market, but the lens quality at the fringe were usually too bad for a nice stitching. We made our purpose-built lens for stitching 3D360 video, and this handy dual fisheye setup soon become a gear in my bag. Interested parties can feel free to reach me for a trial.
