What is NURBS?

It is a Non-uniform rational basis spline (NURBS) is a mathematical model commonly used in computer graphics for generating and representing curves and surfaces which offers great flexibility and precision for handling both analytic and freeform shapes.

NURBS are used great on complex modelling such as gaming characters or object that has a large number of details.It is easier to adjust the forms and proportions as there are more accessible control points for modifications than polygon primitives
