I have one of those Fuji 3d cameras and was interested in trying to view its stereoscopic pics in VR with the Rift.
I did a quick hack to away3d to add a plane that supports stereoscopic textures so each eye receives its over version of the pic and knocked up a quick gallery demo. It works surprisingly well. I expected I would have to alter the offset of each image based on how close the viewer was but no, it seems to work fine
Thought it might be of interest. I don't plan on doing much more with it for now
Also you may need to set your res manually to 1200x800 for best results
