Hi Robert, This might go beyond my original question, but I just want to share my thought about your point. First of all, I think screen distance does have some effect here, since the farther the screen, the smaller the FOV (people have different head shapes, right?). Second, I think iod is not the

Hi Robert, I don't totally agree with your answer. In these two functions computeRightEyeViewImplementation() and computeLeftEyeViewImplementation(), you do use iod, screen distance and fusion distance in computing the view matrices.
