A Non-Uniform Rational B-Spline (NURBS) is a mathematical model used in computer graphics and computer-aided design (CAD) to represent curves and surfaces. NURBS are powerful because they can accurately represent both standard shapes (like conic sections: circles, ellipses, parabolas, etc.) and freeform shapes.
