B-spline patch

Quick Reference

A surface patch defined by B-spline curves in the same way that a Bézier patch is defined by Bézier curves. Given a characteristic polygon defined by vertices



i = 0,1,…p,

j = 0,1,…q,

the B-spline patch is defined bywhere B is the B-spline basis function of degree ρ.
