How would you forget is likely the superior question. At any rate, GoPro has just announced the general availability of that very module, with $99.99 getting you a waterproof 3D expansion kit for the insanely popular HD Hero camera. For those who've forgotten, the kit allows a pair of 1080p lenses to form a single 1080p 3D camera, and it's waterproof to 180 feet, too. In related news, it seems as if GoPro has also taken this opportunity to snap up CineForm, and it's wasting no time in putting the outfit's compression and workﬂow technology to good use. Customers can surf over to to GoPro's website in order to suck down a gratis copy of CinaForm Studio, which makes it easier on 3D shooters to create, watch and share their three-dee imagery. The app also converts 2D material into 3D H.264 files, and for the price mentioned here, it ain't a half bad inclusion. PR's after the break, if you're so inclined to visit.
