NURBS (Non-Uniform Rational B-Splines)

NURBS (Non-Uniform Rational B-Splines) are mathematical tools used in computer graphics and design to create smooth, flexible curves and surfaces. They work by combining control points, weights, and a special curve formula, allowing precise shaping of complex forms like car bodies or animated characters. The "non-uniform" aspect means knots are spaced irregularly, giving more control over the shape, while "rational" refers to incorporating weights that influence the curve's pull towards certain points. Overall, NURBS offer powerful, precise modeling capabilities, making them essential in industries like automotive, aerospace, and animation.
