I'm a little confused - what exactly are you doing? Are you making the projectors? Are you programming the game? What software are you using? Are you sensing what it's being projected on?

Some of the hardware was built (one of the projectors), some of it is purchased (a second projector due to time constraints, and all of the DACs). The games, graphic engine, DAC comms, etc. are all programmed in a mix of Python and C++. Most projection software available is commercial and expensive, so I've rolled my own stack. I'm working towards surface distortion mapping, which is increasingly important in the umbrella concern of rectifying multiple projectors onto a single coplanar/colinear surface. I'm going to project a series of grids and have OpenCV automatically align all of the projectors. From there I'll be working with a logical "frame buffer" (really coordinate/transform buffer) that is relayed over the network to a graphics server that will dispatch the drawing jobs and topologically sort objects unless they have preassigned projector-affinity. As far as I know, nobody else is building a beowulf cluster of laser projectors for interactive display. That's my endgame. Really fluid, bright, fast laser light with incredible geometric output capacity. It won't be limited to 2D if I can get design a decent wireframe or clipping/culling engine.

  That is just amazing. Keep it up.

  There is a company in Montreal called VYV (I am not associated with them but a friend works there) who are doing lots of projector/projection type work.. I don't know if they work with lasers but they are definitely working on solving the whole multi-projector and distortion mapping stuff that you're tackling.. They might be interested in talking to you, they're still fairly small and startup-ish but they're doing big things.. http://www.vyv.ca/ http://www.vyv.ca/

    I'll definitely look into these guys. I'm unable to relocate right now, but there might be some future opportunity waiting. Thanks for the heads up!
