Surface patch

Okay kiddo, let's talk about surface patches. Imagine you have a big piece of paper, and you want to draw something on it. When you draw, you make lines, shapes, and colors that cover the paper.

Now, let's say you only want to draw on a small part of the paper. You might cut out that small part of the paper and make it into a separate piece. That's kind of like a surface patch.

A surface patch is a small, separate piece of a larger surface. For example, imagine you have a ball that's covered in different colors. Each color might be like a different surface patch.

Surface patches are used in lots of different fields, like math, computer graphics, and even fashion design! It's just a fancy way of talking about a small piece of a bigger thing.
