3D body scanning

3D body scanning is a way of making an exact digital copy of your body. A special machine uses lasers and cameras to capture the shape and size of your body and then creates a 3D image of it. This image can be used to make clothes, fitness trackers, and other things that are customized to fit you perfectly.
