GeomRandom library for random point generation inside and on a surface of 2D and 3D shapes of complex geometry

The aim is to develop and implement a high performance library which allows us to generate random points in accordance with the given discrete probability distribution on a surface or inside geometrical shapes of complex geometry in 2D and 3D spaces. The shapes can be given by a surface triangulation, a composition of geometrical primitives (such as sphere, cone, parallelepiped, cylinder, etc.) or a bitmap image. Discrete probability distribution can be given over a particular primitive and by a table. In case of bitmap images, it can be defined by gray scale tones on the image. The GeomRandom library is intended to be used for parallel construction of adaptive meshes by discrete stochastic methods, for statistical modeling problems, image processing and so on.
