A 3D OpenGL viewer for molecular structures from the output of quantum chemistry calculations.

ViewMol3D uses Windows implementation of workstation-class OpenGL (OpenGL is a trademark of Silicon Graphics, Inc.) 3D graphical system to render molecules as wire frame, sticks, ball-and-sticks and CPK models. The ViewMol3D can draw molecules models from output of several quantum chemistry programs.

In ViewMol3D you can move molecule to near and far.
1. To move molecule near press key '1' and to move far press key '2'.
2. ViewMol3D can display molecule in normal or perspective view. You can switch the viewing modes by pressing key '3'.
3. If your computer too slow or you view big molecule you can view only bonds without atoms by pressing key '4'.
4. If you however want to look atoms you can view atoms as polyhedron by pressing key '5'. This is very speed up molecule rotation.
5. Also you can view instead of cylinder bonds line bond by by pressing key '6'.
6. The view of vectors of frequencies can be carried out by pressing the key '9'. For detailed description of this mode look IR-vectors displaying.
7. To view gradient vectors press the key '0'.
8. As well as you can combine different modes of viewing.

You can start the ViewMol3D by simply typing in command line:
ViewMol3D[.exe] <FileName.(mol/out/gms/mop/xyz)>
where <FileName.(mol/out/gms/mop/xyz)> is name of file what you want to look.

Possibilities
1. Showing the geometry of a molecule
2. Tracing a geometry optimization or a MD trajectory
3. Showing normal vibrations of a molecule as arrows
4. Showing forces acting on each atom in a selected configuration
5. Saving all generated pictures as BMP/PNG file.

File Formats Supported
1. Gaussian 9x/03 OUT files
2. GAMESS(US)/PC GAMESS OUT files
3. MOPAC/AMPAC OUT files
4. XYZ files with Cartesian coordinates
5. Tripos Alchemy MOL files
