Goals/Tasks

1. Repetition of unit cell to make crystals

2. Differences in SC, BCC, FCC, HCP and various simple ceramics structures

3. Conventional unit cell (use shift in three directions)

4. Contact condition for atoms (by changing atomic radius)

5. Close-packed directions and close-packed planes

6. Draw planes for Miller indices

7. Explore crystals by rotation and zoom

The last may run slowly, so be patient when there are many 3D spheres and planes to draw!
