An interactive applet for drawing crystal structures

CrystalOgraph allows you to draw interactively on the screen any simple crystallographic structure by specifying the lattice constants space group and the coordinates of the symmetry independent atoms. The structure parameters can be either entered by hand on the screen or from a selection of examples.

In addition to the panel functions, the following key combinations can be used:

  • Rotate the structure: Drag the mouse inside the screen.
  • Rotate around the normal to the plane: Shift+drag the mouse or mouse right button.
  • Zoom in/out: Alt+drag the mouse or mouse wheel or up/down arrow keys.
