3D Motion Capturing part 2: Drawing In Space

// May 9th, 2009 // Experiments, Flash 3D, Webcam

In my previous post I did a first test with 3D motion capturing, it worked, but it wasn’t precise enough to make a 3D drawing app (my initial plan). I did some more experiments with normal web-cams, but they all failed. There was to much “color pollution” to track a small point.  So I decided to try it with infrared light.

That did the trick:

I had to build a simple infrared ‘pen’ (picture below) and convert 2 web-cams to infrared web-cams.

How: Open the web-cams. Replace the infrared filters with a filter that  blocks all the visible light but won’t block infrared light. Film-negative does that for you.

    Jouw blog staat vanaf nu in m’n favo’s! Zou jij niet de man zijn om bij Sony een soort van EyeToy 2 te ontwikkelen voor de PS3 ;)
    Respect voor je werk!
