Translations:B-Splines/33/en

This video lists at the beginning the practical problems with Bézier curves. For example that adding or changing a control point changes the whole curve. These problems can be resolved by joining several Bézier curves. The result is a so-called spline, in particular a B-spline (basis spline). The video also explains that a union of quadratic Bézier curves forms a uniform quadratic B-spline and that a union of cubic Bézier curves forms a uniform cubic B-spline.
