VESTA is a 3D visualization program for structural models and volumetric 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 with full use 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
