What are Spherical and Cylindrical 360º VR-Images ?
SPHERICAL 360º VR-Images records the full spherical environment: 180 degrees up and down and 360 degrees around. Apple Computer who originally delivered the technology calls it Quicktime VR (QTVR) or Cubic VR’s. CYLINDRICAL 360º VR panoramas are limited view panoramas and do not need the requirements to see fully above and below. These panoramas are typically imaged with a field of view (fov) of 100 x 360 degrees or less. These are taken for subjects that are best suited for limited views like city sky lines and group photos. Cylindrical panoramas are also used for print presentations.
