Title: Design with smooth rational geometric spline curves based on fractional decomposition (GP. Bonneau)

red line


A well-known result of algebra is used to find a special parametric representation of rational curves. Some properties of this representation are given: derivatives of any order in any parameter value are written in a closed form, and an exact integration formula for non-parametric rational curves is given. These results are applied to find rational geometric spline curves which interpolate or approximate given points, and minimize an energy functional.
