This complex model displays facets of a diamond crystal, along with their Miller Indices. But this crystal doesn’t seem to have any perpendicular x, y, z axes upon which to base those cubic indices!
That’s because those axes are not based on bond directions. They are based on the crystal’s "unit cell" - the natural atomic building block from which the crystal can be constructed. That unit cell is indicated by the dashed cubic box. To pare away atoms outside that unit cell, click the "step forward" button below.
Click that button again to see corresponding model from the previous scene. Click a third time to see the unfaceted crystal. (Continue clicking forward to repeat this sequence, or move backward by clicking the other button).
(Rotate & zoom the model using mouse or trackpad)
