What is 3D scanning?

3D scanning is like taking a photo of something, but instead of just showing how it looks, it shows how big and shaped it is in all directions.

Imagine you have a toy block that’s your favorite. If you wanted to copy it exactly, not just draw it, but make another one the same size and shape, you could use 3D scanning. It works like this: a special machine looks at the block from many angles, like taking lots of photos around it. Then it uses all those views to figure out every detail of how the block is shaped.

How It Feels Like Touching Something You Know

Think about how you know what your backpack feels like when you touch it, you feel its bumps and edges. A 3D scanner does something similar, but with light or lasers instead of your hands. It “feels” the object by seeing how the light bounces off it from every side.

Once it has all that information, it can make a copy of the object, like a digital clone you could print out or use in a game!
