The Foundry just solved live action stereoscopic VR 360

Camera rigs for VR(especially gopro ones) are very flexible, not always precise and the geometry is often changing so many times you do want to re-solve for it if you are removing any cameras to change out batteries, et

Yes this is usually the case with Gopro stereo 3d printed 360 rigs and it is unfortunate but it is possible to have accurately repeatable camera holding arrangements even with Gopros.

Do you have working links for those docs? The pages appear to be down and I can't find an alternate source for the paper on google.

... they are working for me just now .. the Micoy home page is distinctly uninformative but their patents are easy to find .
Their tech is used in the Marvel travelling dome road show I think currently.
