  4. Press Start

###The code

How does it works

FaceAPI is a powerfull real time 2D tracker. This software track the head-position in 3D providing X,Y,Z position and orientation coordinates per frame of video. Opentrack allow us to send this via the UDP protocol, on the local server. The head position data is stored in the ram. With unity 3D, the script UDPRecieve read the bytes, and decode it from hexa to float.

The UDPRecieve c# script is located in the Standard Assets folder, to be compiled before the javascript script. By doing this, we can make a gap between c# and javascript.
