Augmented reality - Image size transform

http://stackoverflow.com/questions/11387535/augmented-reality-image-size-transform

Let us make another assumption to simplify the process. Lets assume that instead of viewing the real arc we view the hypotenuse of the viewport. When looking from a distance d with a view of 90 degrees the hypotenuse of the viewport will be hypotenuse.. the real arc we view the hypotenuse of the viewport. When looking from a distance d with a view of 90 degrees the hypotenuse of the viewport will be hypotenuse 2.83 d Note 2.83 is approx. 2 sqr. root of 2 Step 4 Conclusions And Application So if.. of the viewport.
