The aim of this assignment was to create an live-interactive installation using forces as parameters using Kangaroo as main engine. The main goal was to build a simple interface where the user can “play” with inputs such as attractors, sliders, functions and time to transform an object in space.

This Helium Pavilion is not only evidence of a projective and constructive exploration for temporary installations, but it especially references the interesting capabilities of inflatable architecture;  light, easy to assemble, flexible, economical and nomadic. The selected location for the installation was the IaaC rooftop.


1- Drawing a rectangular curve to define the perimeter of the base mesh.

2- Defining the mesh height in the z-axis.

3- Defining the mesh corners as anchors and projecting them to the base and convert the projected points to anchor points.

4- Defining the mesh length factor.

5- Deconstructing the mesh to apply the load component in the upward direction. 

6- Defining the collision component between the balloon and the mesh. 

7- Combine the data and apply it to the Kangaroo Physics solver.

8- Define the final mesh.





1. The mesh size is enlarged

2. The mesh gets less density

3. A third helium balloon is added
