a grid of points hangs pinned along the top edge, connected by structural, shear, and bend constraints, integrated with verlet. drag any point to move it — the cloth deforms and settles. cut mode slices constraints where you drag. pins mode lets you add or remove anchors along the top rows, so you choose how it hangs. material swaps the weave — linen, silk, burlap, or wire mesh, each with its own weight and drape. wind pushes it gently sideways. left alone for eight seconds, the cloth pandiculates on its own.
