Bézier Extraction

Perhaps the most important concept to understand in smooth-spline FEA is called Bézier Extraction – extraction of the piecewise Bézier elements (composed of Bernstein polynomials) that constitute a basis-spline (aka B-spline). One can actually extract any arbitrary family of piecewise elements (e.g. Lagrange), but we’ll cover that in a future post. The Bézier extraction processContinue reading “Bézier Extraction”
