Molecular Explorer is a powerful WYSIWYG OpenGL graphical editor with several unique features to visualize structures for atomistic calculations. We are very close to a stable beta release!. The above binary is for Ubuntu 12.10 (64 Bits).

Here a short list of features:
+ Load file from CLI.
+ VASP Materials Project format.
+ Generate DL_FIELD molecular structure with DL_POLY format.
+ Periodic and non-periodic systems.
+ Uni/two-dimensional structure scans.
+ Fragment manipulation.
+ Based on the FLTK library therefore very fast and small.
+ Automatic fragmentation of non-bonded parts for counterpoise calculations.
+ Automatic molecular integrity recognition of split structures due periodic boundary conditions.
+ Read several standard files, such as: xyz, pdb, Gaussian, VASP, DL_POLY.
+ Convert structure files between the supported formats.
+ Build periodic systems using images of the unit cell.
+ Series of structures for Potential Energy Surfaces (PES) calculations.
+ Fragment definition to manipulate specific parts of the atomic structures.
+ Display labels for the atomic species (e.g., DL_POLY).
+ Distance and angle tools.
+ Keyboard shortcuts.
