Sur les carreaux de Bézier rationnels de degré 2. Partie 2

Abstract : Following our previous reports related to classical Lagrange finite elements of degree 2, we consider the case of rational Bézier patches not as a method to define a surface (and then a mapping from $\R^2$ to $\R^3$) but as the support of a calculus (therefore a mapping from $\R^2$ to $\R^2$). In this usage, the jacobian of the mapping must be positive and this is the point discussed in this report for both a quad patch and a hex patch (Part 1). Hereafter, Part 2 discusses the case of triangular and tet patches.
