A few images of the connection annotation. A three-digit number is applied to each connection describing:
-The number of the panel in the x direction
-The number of the panel in the y direction
-The edge of the panel : 0,1,2,3
This image shows a version with 2 connections up & 2 connections down for each panel.
A second iteration was produced which gradients the normal of the connection based on the surface curvature. Not sure about its structural consequences but could be a nice detail….
