Audi had a huge presence at this year's Goodwood Festival of Speed in the south of England. We worked with HMC Interactive to build Audi an interactive wind tunnel simulator that their visitors could play in and use to learn about the basic principles of aerodynamics.

We were responsible for writing the computer vision and smoke simulation software for this project. It is written in C++ using OpenFrameworks, it utilises OpenCV for computer vision. To get the smoke flowing realistically we wrote our own particle system that ran directly on the GPU using custom GLSL shaders.
