How to retrieve the coordinates of 4 IR points?

[JeromeGsq]

I added 4 IR leds around my screen. I would like to know the position of the 4 points. This is possible with the "WiimoteLib" library but I would like to do it with Unity. I also see that the sample has 4 points, but only 2 are displayed at the same time. I looked in the code, but I didn't find anything useful for my request. Thanks
