As of Mathematica 8, the functionality of the Wavelet Explorer add-on has been integrated into the Mathematica kernel.
AllPoints
(Computational Geometry Package Symbol) AllPoints is an option to ConvexHull that specifies whether all distinct points on the hull or only the minimum set of points needed to define the hull are returned.
BoundedDiagram[{{a_1, b_1}, ...}, {{x_1, y_1}, ...}] yields the bounded Voronoi diagram of the points {x_1, y_1}, {x_2, y_2} ..., where the bound is the convex polygon formed ...
ConvexHullArea[{{x_1, y_1}, ..., {x_n, y_n}}] gives the area of the convex hull of the bivariate data.
ConvexHullMedian[{{x_1, y_1}, ..., {x_n, y_n}}] estimates the median to be the mean of the bivariate data points lying on the innermost layer of the convex layers of the data.
ConvexHull
(Computational Geometry Package Symbol) ConvexHull[{{x_1, y_1}, {x_2, y_2}, ...}] yields the planar convex hull of the points {{x_1, y_1}, ...}, represented as a list of point indices arranged in counterclockwise ...
DelaunayTriangulation[{{x_1, y_1}, {x_2, y_2}, ...}] yields the planar Delaunay triangulation of the points {{x_1, y_1}, ...}.
DelaunayTriangulationQ[{{x_1, y_1}, {x_2, y_2}, ...}, val] gives True if the triangulation of the points {{x_1, y_1}, ...} represented by the vertex adjacency list val is a ...
DiagramPlot[{{x_1, y_1}, {x_2, y_2}, ...}] plots the Voronoi diagram of the points {{x_1, y_1}, ...}. DiagramPlot[{{x_1, y_1}, {x_2, y_2}, ...}, {q_1, q_2, ...}, val] plots ...
