Synthetic weaving

A small sample of synthetic weaving on a square-grid map. The orange scaffold strand follows an A-trail in the medial map.The short staple strands each cover almost two medial edges, producing stiff, 3-ply strut-like sections between crossings.

Staple strands extend straight-across the crossing, producing an 'elastic hinge' joint for the four struts that meet there.

Two A-trails in the medial from two different spanning trees in the dual. No computation needed: the A-trail mirror reflects off of primal edges and spanning tree edges, respecting the latter when there is a conflict.
