I was recently at the Brooklyn Museum for the opening of the exhibit Coney Island: Visions of an American Dreamland, 1861–2008. Its a great exhibit and I encourage everyone to go check it out! While there, I took the time to take pictures of several objects to use to generate 3D models of a few Coney Island Artifacts, as well as some beautiful architectural details.
This process of photogrammetry or “physical photography” as I have come to call it involves photographing an object many times from all angles, taking care to ensure that each image is in full focus. Once photographed, software analyzes the image to find the same point in multiple images and generates a 3D model of where in space each camera was. From there, a point cloud and 3D mesh can be generated. Its a laborious process but its a very accurate way of generating 3D models of still objects like sculpture.
Here’s the processed scans:
