Concept

O3 Pavilion was inspired by the ozone trioxide molecule. The three atoms of oxygen become three spaces of experience of the concept pavilion of the Docol. Each atom has a unique multi-sensory experience which contextualizes the public in relation to the respective products on display.

Computational Design

The O3 Pavilion was conceptualized by the Atelier Marko Brajovic at the same time that I was taking my first steps into the computational design world. I had just graduated from FAU-USP with a thesis in which I learned all the tools necessary to finish this pavilion: Rhino, Grasshopper 3D and Kangaroo Physics.

My role in this project was to work on the form-finding and the production of data for digital fabrication.

Form Finding

The form-finding was specially tricky in the intersection between domes. Because each dome had a unique shape, the Voronoi cells at the intersections did not match. I had to use the Kangaroo plugin to force opposite dome cells into the same shape. And in doing so, the rest of the pavilion had to relax while keeping the domes planarity.

Animation of the form-finding: Kangaroo forcing cells to be planar.

This is the latest Grasshopper file I used in the project:

Fabrication

The fabrication process wasn’t on our hands though. It was under a sub-contractor in the south of Brazil: Paleta Stands. There was a big logistic puzzle on the pre-fabrication and transportation which I was not part of, unfortunately. This is exactly what I talk about in the paper presented at the SIGraDi 2018 conference in São Carlos, Brazil.
