Note to nerds: or possibly a lattice, narrowing toward the top; it's not the shape that matters here but the idea that there is at least a partial order.

对Nerd们的注解：可能是个格，顶尖；形状不重要，这里至少有个偏序关系。

Given a lattice symmetry, larger absolute photonic band gap was achieved by selecting an air hole shape of the same symmetry.

Groups of those meshes are formed into a 3D shape, then seeded with cell cultures, which grow to fill in the lattice to create the final system.
