This thread is OUTDATED - for up-to-date information about 'Stereoscopic 3D / Oculus Rift Support' please see this new thread there:
krpano 1.19 (Pre Release) - WebVR / MobileVR / Stereoscopic 3D Support (Oculus Rift, Google Cardboard, GearVR, ...)
I recently got my Oculus Rift (btw - a very great device ) and I of course tried to use krpano with it.
Here are the results of that try:
The panos can be viewed in any HTML5 capable browser that supports WebGL and the HTML5 Fullscreen API.
Additionally there are also demos for viewing the stereoscopic panos on common 3D TVs. By using a Side-by-Side (SBS) rendering its possible to view the panos also on all common 3D TV screen that are supporting are 3D mode (should be almost all).
For all Oculus Rift owners - have fun watching the panos!
