Vicon Tracker 2.2 integration with Unity 3D

@unity_2qEYo_LYOfShGQ

I've not specifically integrated a Vicon tracking system with Unity, but I have integrated a couple others. My guess is that the Vicon coordinate system and the Unity coordinate system are not the same, so you're going to have to transform the Vicon data into the Unity system.

For instance, we know that the Unity coordinate reference is X (right), Y (up), and Z (forward). Note, that the coordinate system is left handed. Let's say that the tracker coordinate system is X (forward), Y (right), Z (down). [Note: system is right handed, and is common] You'll need to modify the position coordinate so that...

 x' = y
 y' = -z
 z' = x

And, assuming your getting Euler angles, rx, ry, and rz...

 rx' = -ry  
 ry' = rz
 rz' = -rx

Does that make sense?

FWIW, there's a Vicon plugin for Unity here. Don't know if it's compatible with your version, but I'd certainly download it and check it out.
