The Eye Tribe

I am working with custom software, and I'm attempting to make a "show eyes" function before calibration where you can see if the tracker is picking up on your eyes, and then position yourself correctly with regards to the appropriate distance away from the tracker. This is similar to what the eye tribe UI does, so I'm assuming it can be done? Do you know of an easy way to get these 3D position coordinates (not gaze, but position of the head with regards to the tracker) in Python through the API?

You should look at fetching pupil coordinates from the frame object as documented by the API
