This is one of those practical applications of photogrammetry where creating 3D models or scans protects and help preserve and better understand the ocean and coral. The 3D models in addition to looking amazing and artistic generates a rich amount of accurate geometric and volumetric data so you can track growth or unfortunately the deterioration of coral colonies due to several environmental factors in our oceans. The ability to document a coral in 3D with textures is far more rich than 2D underwater sketching or 2D photos. Sly uses Autodesk Memento to generate 3D textured models of coral from photos he and teams take underwater in coral reef locations around the world. Our good friend and a smart innovative marine scientist Sly Lee of The HYDROUS had a nice online piece covering his work in.
