I did this for my diploma last months ;D
I tried it with Eyesweb before, like you want to. But finally I made all stuff with Vvvv because of performance reasons. In Eyesweb all is Cpu rendered, in Vvvv I wrote some shaders and the most stuff then is on Gpu, what is incredible faster.
The most important thing for using Vvvv or Eyesweb is:
->What kind of interaction do you need?
For more advanced data about movement I recommend Eyesweb. If you just need something like “Buttons” or pixelcollisonbased interaction Vvvv is the choice. I just needed pixelcollision.
At moment I postprepare my diploma and later I will post some interesting stuff for community. But this needs some time - comments for all shaders, help for modules, …
Some tipps for you:
-Most Beamers dont have Infrared-emissions. So best you take an IR-Cam for tracking.
-CCD-Webcams can see IR. They have a little filter between optic and chip. Take it out and put a Lee Infrared-Passfilter (let only IR pass through) to get a cheap IR-Cam.
-Buy an IR-Lamp for healing. Around 5-8 euros for lighting. Put a blue or deepblue Lee-filter in front to filter the rest of visible red light. A very cheap and powerful 100W IR-Lamp. Better than Leds. See pic at top.
-Or second way. Take a normal bulb or PAR-Fixture and put deepblue and deepred Lee-Filter in front. This filters all visible light. Only IR will pass - its around 60% of normal bulbs - they produce more heat than light! I had done little IR-spots with Halogenpins like this way.
Just in short: Diploma is an exhibition design about digital filmproducing - a filmmuseum. The idea behind is to have some interactive installations where the visitor can replay the technologies. One of several themes we had build.
This is Composting-Installation. The visitor can walk in the room and seeing hiself doubled in a mediaroom. With his mediabody he shifts some layers (the tech behind compositing) in the image by pixelcollision. The visitor plays a little (very straight) game “help the dancing girl”.
Techs: 2 PCs, one is colortracking from above, 2 Webcams, other is showing projection and pixelcollision from behind, 1 IR-Cam, 1 Dv-Cam
Same in Infrared
I think best point to start is to think about your interaction.
If you have some questions, feel free to ask.
