Detailed Description

Extra- and interpolate in 2D.

This class implements a kind of Delaunay triangulation. It calculated the Voronoi points and the corresponding Delaunay triangles. Within each triangle a bi-linear interpolation is provided.

A special selection criterion is applied for points outside the grid, so that extrapolation is possible. Note that extrapolation of far away points (as in the 1D case) is not recommended.
