Image showing 8000 orthorhombic I Wigner-Seitz cells 20 x 20 x 20 Wigner-Seitz cells for an Orthorhombic I lattice, with 1.0, 3.0 and 3.1 lattice parameters, seen from the inside, projected in perspective (the little dots inside are the nodes). GAMGI is now running also on Mac OS X (10.1.2), thanks to the Fink project. The window manager seen here is Blackbox. Size: 100,454 bytes.

Image showing transparent layers with different cells and lights Three transparent layers with different lights in a single image: one layer with 10x10x2 conventional cells for an Hexagonal lattice with parameters 1.0 and 1.633, plus one conventional, primitive and Wigner-Seitz cells for an Orthorhombic I lattice, with lattice parameters equal to 1.0, 3.0 and 3.1 and no lights, a second layer with 3x3x3 Wigner-Seitz cells for a Cubic I lattice and a grey light, plus a third layer with 3x3x3 Wigner-Seitz cells for a Cubic F lattice with a greenish light. Both lights are directional, these ones have only diffuse and ambient components. GAMGI running on Yellow Dog GNU/Linux 2.2 on a PPC Titanium notebook, with Enlightenment and the marble GTK theme. Size: 82,911 bytes.

Image showing C20, C30, C40, C50, C60, C70, C80, C90 and C100 fullerenes C20, C30, C40, C50, C60, C70, C80, C90 and (you guessed...) C100 fullerenes, drawn in solid mode, with a grey directional light. The layer has an orthographic projection to emphasize the molecular symmetry.

Image showing occupancy rules for sphere and conventional cell volumes Occupancy pattern rules at work, here with Cubic P lattices. Above, a cube of Si surrounded by C in a spherical volume: C (___***, ___***, ___***); Si (*2_, *2_, *2_). This is usefull for example in hidration studies, say, a silica cluster surrounded by water molecules. Below, 5x5x5x5 Conventional cells: 1) C on the left and Si on the right: C (*2_, *, *), Si (_2*, *, *); 2) alternating octant cubes with C and Si: C (*2_, *2_, *2_), (_2*, _2*, *2_), (_2*, *2_, _2*), (*2_, _2*, _2*), Si (*2_, *2_, _2*), (_2*, _2*, _2*), (_2*, *2_, *2_), (*2_, _2*, *2_); 3) C alternating with Si: C (*_, *_, *_), Si (_*, *_, *_). This is usefull for example to study liquid mixtures, say, of molecules of water and ethanol. Cells are shown with edge borders and orthographic projections to reduce clutter. Image taken on a PC running GNU/Linux Red Hat 5.2 with AnotherLevel and Lesstif. Size: 11,063 bytes.
