✦ Synopsis


The motivation of this paper is to develop a local scheme of constructing G 1 smooth B-spline surfaces with single interior knots over arbitrary topology. In this paper, we obtain the conditions of G 1 continuity between two adjacent biquintic B-spline surfaces with interior single knots. These conditions are directly represented by the relevant control points of the two B-spline surfaces. By utilizing these G 1 conditions, we develop the first local scheme of constructing G 1 smooth biquintic B-spline surfaces with interior single knots for arbitrary topological type. The high complexity of deriving the local G 1 scheme is well overwhelmed. The biquintic is the lowest degree for which there exists a local scheme of constructing G 1 smooth B-spline surfaces with interior single knots over arbitrary topology.
