Popis: | Conversion methods are required for the exchange of data. First a given rational B-spline surface with curved boundaries will be segmented by curvature oriented arguments, then these patches will be converted into bicubic or biquintic integral Bezier patches with help of geometric continuity conditions. The given curves with rational B-spline representation of arbitrary order in the parametric domain will be converted into integral B-spline curves of arbitrary order with help of geometric boundary conditions. |
