I recently got an Oculus Rift and realized that if I was taking 185° fisheye timelapses, I could reprocess them into spherical videos for VR viewing! (granted most of the ground is missing). Considering it's my first attempt at such a technique, I'm really happy with how it all turned out! The first time I put a test cut into the rift the other day I was pretty amazed. Hope you enjoy!
Even starting with a 4k*2k image, the resolution is limited because the Rift's HMD is limited, but it still feels like you're standing there and time went nuts, which I think is pretty cool. The lens flare does map out pretty weirdly at night, and the spherical stretching heavily exaggerates my lens' chromatic aberration, resulting in some dark blue fringes near sharp edges on trees and in the observatory, but those are problems to solve with more coding at a later date.
This video is the "sphericalized" version of this timelapse: /youtube/video/4c1VRMUBh_4
