Vanishing point as the "direction point", as lines having the same directional vector, say "D", will have the same vanishing point. Mathematically, let be a point lying on the image plane, where is the focal length (of the camera associated with the image), and let be the unit vector associated with , where . If we consider a straight line in space with the unit vector and its vanishing point , the unit vector associated with is equal to , assuming both are assumed to point towards the image plane. When the image plane is parallel to two world-coordinate axes, lines parallel
(Get to) The Point (Get to) The Point (Get to) The Point is a short-lived current events discussion television program that aired on CNN in April 2013. Initially billed by CNN as "a week of special programming", the program was hosted by advertising executive and television personality Donny Deutsch with a panel that consisted of political commentator and gay rights activist Margaret Hoover, ESPN columnist Rick Reilly and ESPN NFL analyst Jason Taylor.
