3D Obama: The first 3D scanned portrait of a US president
President Obama has become the first US president to have his portrait produced through a 3D scanning process.
The data used to create the bust came from eight sports photography cameras, six wide angle cameras and the use of 50 custom-built LED lights.
The team from the Smithsonian also used handheld 3D scanners to collect peripheral data.
