This page is an interactive visualization of the two canonical embeddings (T and O) of the Aztec‑diamond graph with uniform ($a=1$) or $2\times 2$ periodic edge weights depending on a parameter $a\ne 1$. In the T‑embedding, every face is a quadrilateral with the same cyclic product of edge lengths as in the original Aztec diamond graph. The companion O‑embedding in 2D represents the origami folding of the T-embedding. The 3D view lifts the T‑coordinates by $\mathrm{Im}(O)$.

The 2D T-embedding can be exported in TikZ format using the Export TikZ button below.

Large sizes (n > 100) are computation‑intensive; the code runs entirely in your browser, therefore patience is advised on mobile.
