| The most general form of polynomial patch supported by the rendering library. The B-spline patch uses B-spline curves in both parametric directions. A B-spline provides a smooth approximation to its control points. The most popular form of B-spline is NURBS (nonuniform rational B-spline), where the segment knots are spaced at non-equal intervals in parameter space. | |||||
