VESTA is a 3D visualization program for structural models, volumetric data such as electron/nuclear densities, and crystal morphologies. Some of the novel features of VESTA are listed below.
- Deal with multiple structural models, volumetric data, and crystal morphologies in 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 limit 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 colored on the basis of another physical quantity.
- Arithmetic operations among multiple volumetric data files.
- High quality smooth rendering of isosurfaces and sections.
- Export high-resolution graphic images exceeding Video card limitation.
VESTA is a successor to two 3D visualization programs, VICS and VEND, in the VENUS (Visualization of Electron/NUclear and Structures) software package.
VESTA runs on Windows, Mac OS X, and Linux. It is contributed free of charge for non-commercial users.
- Visualization of crystal morphologies
- Superimposition of multiple structural models, volumetric data, and crystal faces on the same Graphic Area
- Visualization of isosurfaces with multiple levels
- An extended bond-search algorithm to allow more sophisticated search in complex molecules, cage-like structures, etc.
- Calculations of electron and nuclear densities from structure parameters
- Calculations of Patterson-function densities from structure parameters or volumetric data
- Integration of electron and nuclear densities by Voronoi tessellation
- Significant performance improvements in rendering of isosurfaces and calculation of slices
- Output information about principal axes and mean square displacements for anisotropic thermal motion
- Determination of the best plane for selected atoms
- Displaying labels of atoms
- Customization of styles per sites or bond types
- Customization of symmetry operations
- Improvements in inputting files with various formats
- Support of undo and redo in GUI operations

At the end of June 2004, one of the main developer Dilanian leaved the project and both VICS and VEND became unlikely to continue its progress. Then I decided to create a new program employing a modern C++ GUI framework wxWidgets. We at first upgraded VICS to VICS-II with a new state-of-art GUI and further integrated VICS-II and VEND into the next-generation 3D visualization system VESTA, adding new capabilities.
