Lasers + Leapmotion #2

4W RGB Laser, tracking fingers with a Leap Motion, throwing MSAPhysics into the mix.

 

Lasers + Bubble tracking

Using a high-speed infrared camera to track bubbles and other movement, and project lasers back onto the objects.

 

Lasers + Leapmotion

Throwing a Leap Motion into the mix. Leap Motion is a device to track fingers and small pointy objects. Organic blobs of laser sweep to where my fingers are pointing (using ofxLeapMotion by Theo Watson).

 

Laser Hello world

First tests of hooking a laser projector to openFrameworks via the Etherdream DAC.

 

P.S. LASERS ARE DANGEROUS!
The people in these videos are wearing high density safety goggles.
Do not play with lasers unless you know what you’re doing!

 

Open-source openFrameworks addon (C++) for device agnostic ILDA functionality.

ILDA (International Laser Display Association) is the protocol of communication with galvanometer based laser projectors.
