Comparing curves types: B-spline and Bezier

“

- [Instructor] We now compare two different curve types, the Bezier and B-Spline. And then discuss how they relate to a NURBS surface. Some definitions, a little history, and don't worry, we'll make some cool 3-D stuff at the end. First, let's define NURBS. What is it? Not quite. NURBS actually stands for Non-Uniform Rational B-Spline. So these curves are actually an integrated part of the overall surface type called NURBS. Let's now compare and contrast the Bezier versus the B-Spline from Rhino. First, a Bezier, there's a beautiful mathematical formula, and, just kidding, let's go with some images. The Bezier versus the B-Spline can describe a very similar curve, however, the points on a Bezier curve are on the curve itself. And there's handlebars for adjustments. The B-Spline, by contrast, has all the points off of the curve, creating a cage-like system for control. The big difference, though, is that Bezier has three places you can adjust the curve, the point itself, and the two…
