  The Voronoi tessellation is a natural way of space segmentation, which has
many applications in various fields of science and technology, as well as in
social sciences and visual art. The varieties of the Voronoi tessellation
methods are commonly used in computational fluid dynamics, computational
geometry, geolocation and logistics, game dev programming, cartography,
engineering, liquid crystal electronic technology, machine learning, etc. The
very innovative results were obtained in astronomy, namely for a large-scale
galaxy distribution and cosmic web pattern, for revealing the quasi-periodicity
in a pencil-beam survey, for a description of constraints on the isotropic
cosmic microwave background and the explosion scenario likely supernova events,
for image processing, adaptive smoothing, segmentation, for signal-to-noise
ratio balancing, for spectrography data analysis as well as in the moving-mesh
cosmology simulation. We briefly describe these results, paying more attention
to the practical application of the Voronoi tessellation related to the spatial
large-scale galaxy distribution.
