After 3 weeks of die-hard grasshopper scripting it seems that Han Feng and Thijs van der Lely have managed to finish their CAD geometry.
The pavilion geometry consists of 96 cones. Each cone contains 2 cross-sectional construction rings, 192 in total. Where these cones meet each other 422 ribs are put in place. Again, these ribs consist of multiple parts adding up to a total of 1688 components, just to create the connections.
The scripting was done in Grasshopper 0.8.0062 and 0.8.0063 with the use of Daniel Picker’s Kangaroo tool as a circle packer and with the help of Han Feng to make perfect connections for fabrication.
With the help of Grasshopper’s Galapagus tool an optimization was run to create a perfect balance of material efficiency and construction stability.
Overall aesthetic design and construction detail scripting was done by Thijs van der Lely with a helping had of Han for Grasshopper problem solving.
