VESTA

VESTA is a three‑dimensional visualization tool for structural models, volumetric data such as electron or nuclear densities, and crystal morphologies. It can display multiple models, density maps and crystal faces together in one window, with support for several tabs and multiple windows within a single process. The program handles very large numbers of graphical objects—atoms, bonds, polyhedra, polygons on isosurfaces—and provides lattice transformations, super‑ and sub‑lattice generation, as well as calculations of interatomic distances, bond angles, and anisotropic thermal motion.

The software offers high‑quality rendering of isosurfaces and sections, including transparent overlays and coloring based on additional physical quantities. Users can perform arithmetic operations on several volumetric files, generate high‑resolution graphics beyond video‑card limits, and take advantage of undo/redo in the graphical interface. VESTA also supports an extensive list of file formats for importing structural data, ranging from CIF and VESTA’s own format to various crystallographic and simulation outputs.

Designed for researchers and analysts working with crystallographic or electronic‑structure data, VESTA runs on macOS, Windows and Linux and is provided free of charge for non‑commercial use. Its distinctive capabilities include simultaneous visualization of multiple data types, advanced bond‑search algorithms for complex molecules, and integration of density calculations with Voronoi tessellation.
