You need to enable java in your browser

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

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.
