Its rather surprising how i find mathematics come to my rescue everytime i get stuck with an aeromedical problem.
I just wish we had better teachers in maths in school and then maybe i wouldnt have hated the subject so .. at that time.
anyways this article is a simple application of three dimensional geometry common sense and some simple trigonometry to predict the head movement of a person when seen from an off centred camera.
An over simplification actually since in real life using calculus would give a better approximation.. but then we live with our limitations i guess
