Our Planet is an interactive installation developed for an international sustainability exhibition that attempts to decode some of the more complex and contentious issues surrounding climate change, the exhibition itself was part of a larger initiative that aims to help children develop an understanding of their relationship with the environment.
As a response to the brief, I developed a large spherical interactive touch-screen to display a constantly rotating planet Earth. Instantly recognisable, yet striking in the unfamiliar context. I developed a simulation of weather patterns - hurricanes and other natural phenomena - that showed the planet in constant flux; as a perpetually shifting and evolving. It would react to the approach of visitors, forming the storms as they drew closer; butterflies would fly from their fingers when they made contact, circling the globe before dispersing. More aggressive actions would create more immediate and pronounced effects, spinning the entire planet into a chaotic spiral.
Aside from the challenge of efficiently tracking user interaction on a spherical surface, the biggest hurdle by far was developing a system that could project a spherically correct image in real-time. One that not only looked correct, but could also be rotated arbitrarily on any axis.
The tracking system, projection mapping and generative graphics were all developed in Cinder, a c++ framework for creative coding.
Further information on the more technically detailed aspects of this project will be available on the blog soon.
