Bezier curve

Have you ever drawn a picture or a letter and wanted it to have a nice smooth curve instead of a straight line? Well, that's where a Bezier curve comes in.

A Bezier curve is like drawing a line by connecting a bunch of dots that are spread out in a certain way. The dots are called control points, and they help you make the curve you want.

Imagine you're drawing a smiley face. You want the mouth to have a nice curve. So you put 3 control points on the canvas - one on either side of the mouth and one in the middle. Then you drag them around until you have just the curve you want.

This is called a quadratic Bezier curve because it has 3 control points. But you can also have a cubic Bezier curve with 4 control points. It's like putting an extra point in the middle to make even more detailed curves.

Now, the math behind it can get pretty complex, but basically what's happening is that the computer is using some fancy formulas to connect the dots and make the curve look smooth.

So, next time you want to draw something with a nice curve, just remember that you can use a Bezier curve with control points to get it just right!
