WebNatural-neighbor interpolation is a fast, robust, and reliable technique for reconstructing a surface from irregularly distributed sample points. It faithfully preserves input data values … WebFigure 2. Definition of the natural neighbour co-ordinates of a point x. The Thiessen interpolant is a piece-wise constant function, defined over each Voronoi cell. It defines a method of interpolation often referred to as nearest neighbour interpolation, since a point is given a value defined by its nearest neighbour.

WebNatural neighbor. Natural neighbor interpolation creates weights for each of the input points based on their assumed “area of influence”. These areas are determined by the generation of Voronoi polygons around each input point.
