| Abstract: | The problem of joining surface patches smothly is of great importance m the area of Computer Aided Geometric Design(CAGD). Using the differential geometric approach,The condiuon which ensures GC~2 continuity between two adjacent vector valued surface patches has been presented. Since the given method is also suitable for the special case that the common boundary carve is an asymptotic line of the surface, it makes up the theoretical deficiency in 1]. |
