A rational cubic C/sup 2/ spline curve is described which has interval and point tension weights for manipulating the shape of the curve. The spline is presented in a local support basis form, and the effect of the weights on these representations is analysed. Subsequently this work has been extended for the modelling of interpolatory curves through B-spline formulation.
