WebThe de Boor algorithm is shown graphically in Fig. 1.12 for a cubic B-spline curve (). If we compare Figs. 1.6 and 1.12, it is obvious that the de Boor algorithm is a generalization of the de Casteljau algorithm. The de Boor algorithm also permits the subdivision of the B-spline curve into two segments of the same order. WebIn the first step of de Casteljau's algorithm we define a point along a line in terms of t t t t. For example, if we have a line between two points, A \blue{A} A start color #6495ed, A, …
