For the better understanding of what happens during a visual experiment, the possibility of recording the experiment itself and watching it again at a later time is crucial. While for many cases achieving this is just a matter of recording the event with a camera, some complex situations require more attention. One such case is when the nature of the experiments is to understand 3D data, where a 2D video would not carry the necessary information. This thesis aims at recording 3D trajectories of small bubbles moving in the air. This is achieved by combining the information provided by a set of synchronized cameras, observing the experiment.
