Mimosa pudica (Sensitive Plants)(grasshopper)

Video Inside


含羞草經過觸及之後
會產生收縮的狀態
運用Grasshopper來模擬其形態

Mimosa pudica (Sensitive Plants):
when you touch its leaves,
it will contract its leaves.
We use grasshopper to simulate
this motion.

簡單的先做出定義單片葉子的三條弧線
將其平均分割取得分割點後
將其中軸線與左右兩側的弧線連線
得到分支枝葉的軸線


simply draw 3 curves to define the leaf
and divide the curve to get the curve points.
Connect the curve point from middle curve to the side curve
to get the axis of the little leaf.


再來每一單枝小葉子依照他中心分割點的向量
用series做漸層的旋轉
並做出pipe做為枝葉的葉子主體

Then each of the little leaf axis rotate
by the curve point on the middle point's vector,
and also populate the pipes by the little leaf axis to
get the body of the leaves.  


最後 旋轉葉片而成五瓣之含羞草
After All, rotate the leaf to make the Sensitive Plant
