This is a 3D scan of a Hunebed (or dolmen) in Emmen, the Netherlands. The 3D scan was made with Artec Eva and Artec L 3D scanner. De color was added during post processing. The Hunebed is D45. It was quite difficult to scan since it's such a large object.
You can watch the real Hunebed in this link. http://www.hunebeddenwijzer.nl/hunebedden/hunebed-d45-bij-emmen/
