# Visualization of all hcp voids

There are 12 tetrahedral voids and 6 octahedral voids in hcp unit cell but I can't find any image that can show all tetrahedral voids and all octahedral voids in hcp unit cell (the common picture in Google shows 2 octahedral voids and 3 tetrahedral voids). Could someone help me to draw or find visualization image of all voids in hcp?

Thank you.
