The values are still quite blobby, we need either a new unwrap through hugin or convert the coefficient values in the vive json.

Any news on that?

There has been some extensive research regarding correct lens variables and new methods of calculating distortion coefficients, no new readings have been made for the Vive yet, and the ones in this pull request are not good enough to merge.

There are also distortion values in the Vive json config that someone could try to convert to OpenHMD/panotools/hugin values. Maybe they use those internally in SteamVR to create their distortion mesh?
Apparently they use a model they name DPOLY3, and apparently there is documentation in the SteamVR HDK on what exactly it is, but maybe it also isn't hard to find out what it is without the documentation.
