Align : Move in the same direction as your neighbours. 2. Cohesion : Remain close to your neighbours. 3. Seperation : Avoid collisions with your neighbours. Attractor methods: (Controlling the shape) From starting points move to target points to create bridge. Using swarm simulation in Grasshopper is in this post: Swarm Python GH Component ...

–蝶跡– Description: 蝶跡的設計啓發於蝴蝶幼蟲，生長成蝴蝶展翅瞬間的造型，以用於圍塑空間形態以及外觀紋理。在結構上也與蝴蝶翅膀振動為靈感之啓發，以最輕薄的木夾板去挑戰材料之彎曲性與結構性，進而產生動態平衡。另外在構造上運用電腦運算技術使複雜造型由416片單元組合而成，以極簡的拉鍊扣合做法連接單元與單元進而產生極複雜細部，在正反的拱肋結構演算下，整體重量平均分攤至7個底座，使整體結構輕量化。 實際走入蝶跡展示庭，空間經驗上，太陽撒入木板因彎曲曲度而刻畫的開口中，微風飄動過整體結構，結構體輕輕飄動而陽光如在樹蔭下似閃爍，就像蝴蝶翩翩起舞輕過留下痕跡一般優雅。 –pavilionButterflyEffect_Geometry– Not-found –pavilionButterflyEffect_step01 Definition– –pavilionButterflyEffect_step02 Definition– –pavilionButterflyEffect_step03 Definition– Not-found –pavilionButterflyEffect_step04 Definition– Not-found –Geometry Size Selection Filter Python Code– ### --Written by Gene Ting-Chun Kao-- ### import rhinoscriptsyntax as rs ids = rs.GetObjects("select surfaces", rs.filter.polysurface) area = rs.GetInteger("selected area limits", 10, 0) rs.EnableRedraw(False) print "Results: All", len(ids), "surfaces selected."

In the past, human beings were known for having strong faith and devoted minds. As a result, church architecture became the bridge between humans and the Creator, the sacred and the secular, as well as darkness and lightness. The best technology at the time was used to deeply affect believers, stimulating them with the powerful ambience of church architecture, and allowing them to ultimately realize that men were as insignificant as a drop in the bucket. ...
