Thanks for your reply, Mattias.

I am still a little bit confused and just want to understand it right.

– Jenny’s answer was: “It is the position of the eye globes regardless of the direction in which you are looking, so it is not the center of the pupil”
– Your answer was: “The eye position is not the center of the eyeball, but better thought of as the position of the pupil.”

Thus, the eyeposition refers to the pupil, but it does not use the exact pupil center? Is it some reflection inside the pupil you use as reference value or what do you use exactly to calculate the eye position coordinates?

Thank you for your help!
