摘要
We consider the interpolation of a given set of ordered data points in R-3 by a smooth curve in the presence of a set of finite or infinite constraint planes, where the polyline joining consecutive data points does not intersect the constraint planes. A method is presented for the construction of the G 2 constrained piecewise rational cubic interpolant which is local. The geometric properties of the Bezier rational cubics are characterized and exploited in the derivation of conditions for the interpolant to avoid crossing the constraint planes.
