Abstract

Various models have been developed for the design of distinct objects and for applications such as font design, computer aided design (CAD), computer aided engineering (CAE), etc. Some methods are better suited for controlling the shape of the curve on an interval, while others are better suited for controlling the shape at individual control points. The work reviews C² rational splines with interval tension and extends this work for the modelling of interpolatory curves and surfaces through B-spline formulation
