document: Universal parametrization in constructing smoothly-connected B-spline surfaces In this paper , we explore the feasibility of universal parametrization in generating B-spline surfaces , which was proposed recently in the literature -LRB- Lim , 1999 -RRB- . We present an interesting property of the new parametrization that it guarantees Go continuity on B-spline surfaces when several independently constructed patches are put together without imposing any constraints . Also , a simple blending method of patchwork is proposed to construct C/sup n-1 / surfaces , where overlapping control nets are utilized . It takes into account the semi-localness property of universal parametrization . It effectively helps us construct very natural looking B-spline surfaces while keeping the deviation from given data points very low . Experimental results are shown with several sets of surface data points
