Abstract | Composite curves and surfaces, obtained by piecing curve segments (and surface patches) of rather low degree have been uued to avoid the involvement of polynomials with high degrees. When two curve segments (or two surface patches) are joined, the parametric continuity or geometric continuity is required to maintain the smoothness at the junction point (or the junction curve). The present study investigates the parametric C1-, C2-continuity and the geometric GC1-, GC2-continuity for Bezier and Ball composite curves, the C1 - and GC1- - continuity for Bezier and Ball composite surfaces of the same type: rectangular-rectangular, triangular-triangular. The conditions obtained for composite curves can be interpreted geometrically, by mean of collinearity or coplanarity of the control points around the junction point of two curve segments. For surfaces, the results obtained, even for low degrees, appear to be quite complicated. As such, they can not reality be interpreted geometrically yet. |
