From Wikipedia "In botany, phyllotaxis or phyllotaxy is the arrangement of the leaves on the stem of a plant.
I'm working on phyllotaxis system in order to construct vertical spiral variations with a rhinoscript code:
-plot an array of points by x,y,z coordinates follwing mathematical logic with several variations
-draws 2 lines in order to draw first petal profile
-divide profile in one array of points defined by the user
-draw circle with previous array points as centerpoint and curvature value of profile petal as radius
-create loft surfaces
-make a polar array to realize final system
"hot" code:

I'm working on my previous diagrid pattern definition, starting from a new interesting definition created by Luis Fraguada. This definition realize a flat panels with aperture controlled by one point attractor and with a shader preview that shows how the panels are shifted from a plane defined by three points, throug a gradient color visualization.
