Quartz: Despite global warming, some reefs are flourishing, and you can see it in 3D. “The videos themselves are an astonishing and important part of the project. Although the corals look computer generated, the videos represent actual reef systems shot with off the shelf DSLR cameras. They are assembled from as many as 4000 photographs, shot by divers who swim lawnmower patterns over the reef, snapping a picture every second. The images are then run through a software process called photogrammetry, which stitches the images together into a 3-dimensional whole, allowing the viewer to glide across the reef with resolution down to one centimeter.”
