Laplacian smoothing

Okay kiddo, so let's say you have a picture that you drew with lines that look a little bumpy or jagged. Laplacian smoothing is like taking a crayon and going over those bumpy lines to make them smoother and straighter.

But instead of using a crayon, we use a computer algorithm that looks at each point on the line and averages it with its neighboring points. The algorithm does this over and over again until the line looks smoother.

Imagine playing a game of connect-the-dots, but instead of drawing straight lines between the dots, you draw curved lines that flow smoothly between them. Laplacian smoothing tries to make those curved lines look even smoother and more natural.

We use Laplacian smoothing in computer graphics to make 3D models or images look smoother and more realistic. It helps create a more polished and refined look that's easier on the eyes.
