3. Fluids in Space

The core of this installation is an example from the Openframeworks addon ofxFlowTools. We expanded that example making it more interactive using a physical interface for interacting with it using the app TouchOSC, which sends OSC messages to OF. What the code does is to translate optical flow in GPU based fluid simulation. The more the movement of the person in the camera, the more the optical flow, the more fluid will come out. Fluid color is based on the color that the camera grab when the fluid is emitted. The interface is a smartphone running TouchOSC, sending OSC messages to OF, controlling different parameters of the simulation as:- Toggle Camera On/Off- Toggle Reset

- Toggle Obstacle On/Off

- Fluid Speed

- Fluid dissipation time

The interface, gives the audience the possibility of changing and experiment with fluids parameter in real-time and find the most pleasants settings. We also have introduced an obstacle for the fluid, with the text "space" which can be switched on/off. The obstacle is not visible if no fluid is emitted. In this way, we wanted the audience to move in spape and discover where the obstacle is.
