Check this out! Archaeologists from ULAS have created a rotatable 3D model of a piece of Roman wall found during an excavation in Leicester.
They have used a process called photogrammetry. During the excavation, lots of photographs were taken of the wall from lots of different angles. These were loaded into a programme called AgiSoft PhotoScan which stiched them all together to create the 3D model. This is a quick and easy way to accurately record something very complex and is a very useful technique for archaeologists.
Click on the 3D button, wait for the model to load then hold down the left mouse button to rotate. Use the scroll wheel to zoom in and out.
