What is NURBS (Non-Uniform Rational B-Splines)?

NURBS are like smart building blocks that help create smooth and flexible shapes, just like how you stack blocks to make a tower or a house.

Imagine you have a set of rubber bands and some pins. You place the pins on a board, stretch the rubber bands around them, and then move the pins around, the shape changes smoothly wherever the rubber band is stretched. That’s kind of how NURBS work! They use points (control points) connected by smooth curves, just like those rubber bands.

Think of NURBS as a special kind of curve that can be adjusted to fit any shape, from a simple circle to the curvy lines on a toy car. It uses both weights (like how heavy each pin is) and knots (like markers showing where the rubber band stretches more or less). This makes it super flexible, like a playground swing that can go high or low depending on how you push.

NURBS are used in computers to design things like cars, airplanes, and even cartoon characters. They help make sure everything looks smooth and perfect, just like how your favorite toy feels when you hold it in your hand.
