Investigation of G4 connection algorithm between adjacent Bezier patches

In this paper, the necessary and sufficient conditions and an algorithm for G4 continuity between adjacent Bezier patches are presented. The effects of shape parameters for surface connection are investigated in details. The algorithm can be generalized directly to the case of higher order geometric continuity for surface connecting. It has important applications in surface modeling, surface blending and surface connecting.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
