【Abstract】 A recursive method used to get the control points of a cubic B-spline curve is presentedand a new interpolating algorithm of a bi-cubic B-spline surface is developed. The algorithmcan get all the control points recursively and quickly without handling boundary conditionsand solving a equation with big dimensions and thus is adaptable to the global interpolationof a complex surface configuration.更多还原
