Dragonfly wing pattern reinforces vaults and domes better than ancient Roman and tech-generated methods

"patterns stiffening ribs enabling withstanding both evenly distributed (topologically optimized best)/ asymmetric (turtle shells and dragonfly wings best) loads... ribs: more rigid counteract twisting, thinner ensures overall integrity... overall best: topological optimization with tight constraint on material expenditure allocating 70% of rib material to primary ribs, followed by parametric algorithm using up remaining filling in thinner secondary ribs (Voronoi pattern)... material conserved, greater creative architectural freedom"
