  abstract =     "Surfaces of $\mathbb{R}^3$ are ubiquitous in science and engineering, and estimating the local differential 
                 properties of a surface discretized as a point cloud or a triangle mesh is a central building block in Computer 
                 Graphics, Computer Aided Design, Computational Geometry, Computer Vision.
                 One strategy to perform such an estimation consists of resorting to polynomial fitting, either interpolation or 
                 approximation, but this route is difficult for several reasons: choice of the coordinate system, numerical handling 
                 of the fitting problem, extraction of the differential properties.
                 \par 
                 This paper presents a generic C++ software package solving these problems. 
                 On the theoretical side and as established in a companion paper, the interpolation and approximation methods 
                 provided achieve the best asymptotic error bounds known to date.
                 On the implementation side and following state-of-the-art coding rules in Computational Geometry, genericity of the 
                 package is achieved thanks to four template classes accounting for (a) the type of the input points (b) the internal 
                 geometric computations (c) a convertion mechanism between these two geometries and (d) the linear algebra
                 operations. An instantiation within the Computational Geometry Algorithms Library (CGAL, version 3.3) and using 
                 LAPACK is also provided.",
