**My FINAL PROJECT**

**GOAL**: I am trying to model an outer skin of a double facade skin facade system constructed by ETFE pillow forms, like the Beijing Water Cube. The goal is to find the optimization of pillow/bubble density on a given facade geometry. I gave the XYZ of the outline geometry a slider so the plane can be in anticlastic form.

**FITNESS**: The fitness will be multi-objectives: for one the bubble size (opening) will be limited by the maximum width of available ETFE foil (assuming 2200mm), therefore we want minimum in size. On the other hand, the skin will be lighted by LEDs installed around each bubble, so the smaller the bubbles are, the more LEDs will be required, hence increase the costs. Therefor we want to keep the total length of the bubble perimeter to minimum, which will drive the opening to be larger.

**GENES**: Density of the bubbles on the given facade, i.e.: the number of the opening which driven by a slider. in addition the random points which generated by two sliders determine the voronoi pattern on the surface.

**PARAMETRIC MODEL**:
