Spiral Morph

A flat rectangular grid and an Archimedean spiral share the same point count. Each grid point's sequential index maps to an angle and radius on the spiral via polar coordinates. A morph slider — modulated per-point by Perlin noise keyed to grid col/row — blends between the two topologies. At low morph values the mesh ripples like draped fabric; higher values unravel the grid into sweeping spiral arcs. The Turns slider controls how tightly wound the target spiral is, producing dramatically different distortions from the same mesh.
