VESTA software is a 3D visualization program for structural models and 3D pixel data such as electron/nuclear densities.
VESTA stands for "Visualization of Electronic and STructural Analysis". It is a cross-platform program written in the C++ language on the basis of OpenGL technology.
Structural models are represented as ball-and-stick, space-filling, polyhedral, wireframe, stick, and thermal-ellipsoid models. Ball-and-stick, wireframe, and stick models can be overlapped with dotted surfaces corresponding to van der Waals radii.
Electron/nuclear densities, wave functions, and electrostatic potentials are visualized as isosurfaces, bird's-eye views, and two-dimensional (2D) maps. VESTA has a feature of surface colorization to show another kind of a physical quantity at each point on isosurfaces. Translucent isosurfaces can be overlapped with a structural model.
VESTA can read 38 file formats such as CIF, ICSD, INS, and PDB. Electron densities calculated by WinGX (Fourier synthesis), PRIMA (MEM), and superflip (charge flipping) can be directly read in. VESTA can handle virtually unlimited number of objects such as atoms, bonds, polyhedra, and polygons on isosurfaces. VESTA supports multiple windows, each of which may contain multiple tabs corresponding to files.
Here are some key features of "VESTA":
· Deal with structural models and 3D pixel data at the same window.
· Support multiple tabs corresponding to files.
· Support multiple windows with more than two tabs in the same process.
· Deal with virtually unlimited number of objects such as atoms, bonds polyhedra, and polygons on isosurfaces (theoretical limits on 32bit operating system is 1,073,741,823)
· Support lattice transformation from conventional to non-conventional lattice by using matrix. The transformation matrix is also used to create superlattice and sublattice.
· Visualize interatomic distances and bond angles that are restrained in Rietveld analysis with RIETAN-FP.
· Transparent isosurfaces can be overlap with structural models.
· Isosurface can be colorized on the basis of another physical quantity.
· Operations of 3D pixel data among multiple files.
· High quality smooth rendering of isosurfaces and sections.
· Export high-resolution graphic images exceeding Video card limitation.
· MUCH better performance than VICS and VEND. For example, bonds search speed in VESTA is several to thousands times faster than that in VICS. Algorithm for calculation of isosurface geometry is more than six times efficient than that in VEND.

What's New in This Release: [ read full changelog ]
· Fixed a bug that resulted in a crash after clicking "Remove symmetry" button twice.
· Enhanced the behavior of "Remove duplicate atoms" button so that duplicate atoms slightly off-centered from a special position will be merged into a single site at the special position.
· Fixed a problem in Mac OS X version that "2D Data Display" window didn't render any graphics unless the window is once resized. This bug exists in v2.0.2 to v2.1.2.
· Added support for file format of VASP 5.2 or later.
· Fixed an issue in Mac and Linux versions that a linefeed character may appear in the middle of title line when exporting input files of RIETAN-FP (*.ins) from CIF (*.cif).
· When exporting files to DL_POLY format, serial number of each site will now be written.
· Updated Madel so that it can handle up to 192 symmetry operations (for some of cubic space group settings).
· Updated the database file for bond valence parameters (bvparm2009.cif).
· Fixed Wyckoff database for non-conventional complex lattices of triclinic space groups.
