Abstract.
An algorithm for interpolating data points with end derivative constraints is presented. The interpolating curve passes through the given points and at the same time assumes the derivatives specified. For degree p interpolation, up to p−1 derivatives may be specified, resulting in C p−1 continuous curve interpolants. The method is useful to piece individual curve segments together or to create closed curves with various degrees of smoothness.
