The ability to use material in directly in fisheye projection could be very interesting, particularly so for video (in krpano 1.0.9).

See for example the panoramic video bits in this promo for a new journalistic video app:

I am pretty sure that the video that has been taken is just a single fisheye shot. No postprocessing would be required to be able to show a (partial) panoramic video experience.

Even parabolic lenses such as the gopro gopano (or 360 one vr) are very close in projection to a fisheye image. So these optics too could be used with very little processing (beyond deinterlacing and cropping), even if at low resolution.

Finally, the whole concept of stitchless / "live" panoramas (livepanoramas.com) could be greatly improved if the viewer supported fisheye projection, though there it would also be necessary to support multiple image nodes, or fisheye distorted hotspot nodes. But as a start, image type="fisheye" would be awesome.

edit: DRATS! wrong forum...

How could I forget this one as a reference?

Soon there will be at least 1347 iphone users shooting panoramic video...

PS: I have not seen footage shot with the gopano micro, so I don't know if its projection is as close to fisheye as is the large gopano.
