Visualize Chemistry with GAMGI

GAMGI, the General Atomistic Modelling Graphic Interface, is a tool for visualizing atomic structures. The project is supported by the Instituto Superior Técnico in Lisbon, Portugal, and is being developed by José Carlos Pereira and others. The software has been released under the GPL, BSD, and GFDL licenses. [GAMGI]

The project's scientific goals state:

GAMGI aims to be useful for: 1) the scientific community working in Atomistic Modelling, that needs a graphic interface to build input data and to view and analyse output data, calculated with Ab-Initio and Molecular Mechanics programs; 2) the scientific community at large, studying Chemistry, Physics, Materials Science, Geology, etc., that needs a graphic interface to view and analyse atomic structural information and to prepare images for presentations in classes and seminars; 3) teaching chemistry and physics in secondary schools and universities, even inviting students to install and run GAMGI at home; 4) science promotion, in schools, exhibitions and science museums.

[GAMGI] GAMGI can plot the following list of objects: "Text, Orbital, Bond, Atom, Direction, Plane, Group, Molecule, Cluster, Cell, Arrow, Shape, Graph, Assembly, Light, Layer and Window."

The GAMGI screen shots give a view of the user interface as well as a wide variety of chemical plots performed by GAMGI.

The technical mission discusses the GAMGI design philosophy and covers some of the system requirements and dependencies: "A really useful package must be easy to obtain, to compile, to use and to change, giving users and developers as much control as possible."

Version 0.11.2 of GAMGI was released this week, changes include: "Crystallographic planes can now be represented by polygons, for all volumes, with minor restrictions. The Cell orientation in a Spherical volume is now the same as for Conventional, Primitive, Wigner-Seitz cell volumes."

The change log file has more details and previews some upcoming features.

The GAMGI source code and packages for Debian and SUSE are available here.
