When computer is used as a tool to design industrial products (e.g. ship-hulls, automobile bodies, etc.) whose shapes vary freely in a complicated manner, a number of building blocks such as splines, Bezier curve segments, B-spline curve segments, are employed to accomplish a beautiful, aesthetically pleasing external appearance for the final object shape and also to ensure that this final shape satisfies a number of prescribed technical specifi- cations. The Graphics Library programming guide for the IRIS system software, which describes the mathematical background for these building blocks, does not appear to give a clear exposition of how one obtains the basis matrices for these building blocks. The present note meets this need.
