Swarm Art 2003 worked differently than the 2002 version. A camera/'''[[CAML | Video Information Server]]''' (see [[Caml-gallery | examples]])in the ceiling looked down on a table full of colored balls. The Video Information Server tracked the balls and fed the ball coordinates to a swarm simulation. The swarm simulation in turn used the ball positions to set simulation parameters. A rendering system displayed the swarm projected onto a wall beside the table.

Here is a nice image giving an overview of how video information servers work.
Camera servers collect and analyze video data in real time, then provide the results
to clients. The client application uses the data to present the ''scene'' to a user. The system off loads the hard work of video analysis to the servers, making complex, useful clients easy to build.

This client tracked vehicle traffic outside the ICT building at the University of Calgary. It operated reliably for a couple of years before we shut it down to use the equipment elsewhere.
The client uses the calibration data from the server to map the video trajectories

This client collected statistical data about regional transitions of vehicles for use in [[http://pages.cpsc.ucalgary.ca/~boyd/papers/mva-boyd-and-meloche.pdf | statistical tracking]]. The user specifies a Voronoi diagram to create regions. The client then uses trajectory data from the server to detect when a vehicle crosses from on region to another.
