Cardboard Camera Toolkit splits (or joins) stereo 360 degree panoramas made by
Google's Cardboard Camera.
Given a photo taken with Cardboard Camera, it can split it into a stereo pair and an audio file. Given a pair of
panoramic images and an optional audio file, it can produce
.vr.jpg format JPEG images with XMP
data suitable for viewing in Cardboard Camera.
