Viewmol is a program for building and editing molecules as well as for the visualization of outputs from quantum chemical and molecular mechanics programs. Currently supported are Gaussian 9x, Gamess, Discover, DMol/DSolid/DMol3, Gulp, Mopac, Turbomole, and PDB files. Properties visualized include geometry (with various drawing modes), vibration (animated or with arrows), optimization history/MD trajectories, MO energy level diagram, MOs, basis functions, and electron density. Drawings can be saved as TIFF, HPGL, Postscript, and input files for Rayshade. Viewmol has an embedded Python interpreter for automation. The program is language independent and currently "speaks" English, French, German, Russian, or Spanish.

This release adds support for Gaussian 03 outputs, (partial) support for
Turkish, and a delay option in resources to control animation speed. The
crash on saving images has been fixed. The dependency on libcxa.so has
Open shells in Gamess and Turbomole outputs are
now supported. Periodic wave functions are also
supported. The ability to read grid data and
visualize them, to read PQS outputs, to read the
Bravais matrix for defining unit cells, to
generate input files for Gaussian, and the ability
to save drawings as PNG files and Postscript
bitmaps have been added. Scripts to set atom
colors through the user interface and to perform
UFF geometry optimization using Turbomole's UFF
module have been included. Python scripts can now
install themselves in a menu. Mac OS X is now
supported as platform.
This release includes an embedded Python interpreter, calculation of thermodynamic properties for molecules and reactions between them, display of Miller planes for solids, reworked moving of molecules (no more molecule fixed coordinate system), changes to the OpenGL/X Windows integration, a lot of bug fixes, and an input filter for Gamess. The user interface has been tranlated into Spanish.
This version fixes bugs discovered since version 2.2 and adds the
ability to change Van der Waals radii (and therefore connectivity) of
a molecule on the fly. Optmization histories/MD trajectories can
now be animated, bindings and icons to KDE aware of molecular
modeling formats have also been provided.
