HFE: curving a panorama
I have a wide panorama (52336x3378, about 180°). I would like to find a way to map this image onto a concave surface so that I can then place a camera at the centre of the curved plane and pan it from one end of the panorama to the other. Is this possible with HFE (maybe with an addon pack)?
Once I have this I'd like to use the Mocha plugin to create some tracked points, using the technique in the 'Tracking Long Pans' turorial - unlinked plains.
Maybe there's a simpler solution. I tried panning the panorama across a composite shot, then applied the Mocha plugin but it either failed saying it's not PTZ, or produced strange points.
