Mesh subdivision

Imagine you have a big line drawing with lots of straight lines and corners. Now imagine that you want to make that drawing look smoother by adding more lines that curve in between the existing straight lines.

Mesh subdivision is a way to do this same thing but with 3D shapes instead of flat drawings. When we talk about 3D shapes in computers, they are made up of a lot of tiny triangles or squares that fit together to make the shape. These tiny shapes are called “polygons” and the more polygons we have, the smoother the shape will look.

So, mesh subdivision is basically taking those polygons and adding more smaller polygons in between them to make the shape look smoother. It’s like drawing a line on a piece of paper and then going over it again and again with a smaller and smaller pen until it looks really smooth and fine.

This is often used in things like video games or animations to make characters or objects look more realistic and smoother. It’s like someone smoothing out their clay sculpture by adding more and more detail until it looks lifelike.
