- •
The method reproduces a conic arc if the input data come from such a conic curve.
- •
The method can reproduce a ‘whole’ conic curve even if it has singularities.
- •
The Bézier control points have well understood geometrical meaning.
- •
The final rational Bézier control points and weights are given in explicit form.
- •
Each of the tangential angles of the given tangent vectors can be arbitrary up to 蟺.
