Points massiques, courbes de Bézier quadratiques et coniques : un état de l'art

Abstract : It is well known quadratic Bézier curves define conics. The use of massic points permits to define a semi-conic in the Euclidean plane. Moreover, from a given quadratic Bézier curve, we can determine the properties of the underlying conic. Moreover, the choice of an adequat non-degenerate indefinite quadratic form permits to see the non-degenerate central conic as an unitary circle.
