B-Spline Knot-Line Elimination and Bezier Continuity Conditions R. G orm az

Many authors have contributed to prove that simplex splines considered as single functions exhibit the same behaviour as theirs univariate analogs. But if we think of B-splines as “base”-splines, the work is far from being accomplished. Among the different schemes proposed since 1982, the one presented in [3] is the first to combine simplicity and good properties.
