For some applications, further subdivision of a segment of a B-spline curve or B-spline surface is desirable. This paper provides an algorithm for this. The structure is similar to de Boor's algorithm for the calculation of a point on a curve. An application of the subdivision is illustrated.
The paper presents pseudocode aloorithms, c-lanouaoe code, and error analysis for removino knots from rational B-spline curves and surfaces. Efficient and easy-to-use aloorithms are presented that, with one call, remove all the removable knots from a B-spline curve or surface.
