A rational cubic C2 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 analyzed. Subsequently this work has been extended for the modeling of interpolatory curves through B-spline formulation.
