NonUniform Rational BSpline (NURBS) provide a parametric mathematical model for generating and representing smooth curves and surfaces.
NonUniform Rational BSpline (NURBS) provide a convenient and efficient manner to generate curved lines and surfaces which can be smooth at any viewing distance. Since these surfaces are generated parametrically, only a small amount of data need be provided for describing complex surfaces. These examples support the X3D NURBS component.  
These capabilities hold significant potential value for use by the Computer Aided Design (CAD) and Medical working groups.
