From the previous bounds of the proscenium tradition – the flat, rectangular space defined by screens and theaters – audiovisuals increasingly sprawl into surround. One superb example comes to us from Seppo Gruendler of Austria.

The project combines multiple “surround” technologies across multiple media. Projection is mapped across screens for wraparound visuals, but sound, too – via ambisonics – extends to 360-degrees.

It’s especially nice to see the full-length video embedded at bottom, for a better sense of what they did.

Users (or prospective users) of the powerful, free and open source graphical patching environment Pure Data (Pd) will be pleased to know that you can take advantage of a big collection of abstractions built for this piece. The Extended View Toolkit combines a range of abstractions, managing multiple video and image sources, panoramic projection, video streaming, and OSC control:

Good stuff, and free. For a good argument for why you should use it, though, check out the full-length work:

    more details on the capture system please. I understand there are three cameras but what does the camera ovelapping, geometry correction etc? What cameras are these, how is the video getting into the computer? what is the box that they are connected into? Interesting stuff, the idea is old but this is the best execution of it I've seen so far

    @peter: Thanks for featuring this here.
    @zbr: all the image processing is done entirely in puredata. the image overlap, lense-correction and in the second set of abstractions, the projection managment is done in puredata as well. The cameras are simple "naked" ps3eye which are connected directly to the computer(which is apparently the black-box). have a look into the toolkit itself to see its features
