NURB curves and surfaces are the industry standard for geometry description in CAD/CAM or  Computer Graphics. 

NURBS  are piecewise rational; they are the logical extension of B-spline or Bezier entitities. 

While those have their roots in affine geometry, NURBS cannot be understood without paying attention to their foundations in projective geometry - this constitutes the first part of the book.

After these foundations have been laid, rational conics and Bezier curves are introduced;
rational B-spline curves (NURBS) follow. As a further extension, the surfaces corresponding to these curves are also introduced. Applications include Pythagorean Hodograph curves and developable surfaces.
