3D tracking prototype #2

leave a comment »

I experimented with video-3D-tracking before here(1, 2, 3).

This is my latest 3D tracking prototype… I added 2 colored leds to the pen to track its position and rotation in space. Also I’ve implemented a 3D model of an actual CT scan… The pen has two different functions at this moment. You can point at the 3D model. And you can switch into a viewing mode in which the pen behaves like a camera, so you can easily zoom and view the (virtual) skull from all directions.


close up photo of the pen…. assembled with electrical tape. You can also see the digital projection of the pen on the lower screen (that is supposed to be the touchscreen)
