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
To the Point To the Point To the Point was an hour-long public affairs radio program co-produced by KCRW in Santa Monica, California and Public Radio International. The program originated at KCRW at 1 pm Pacific Time each weekday. Award-winning journalist Warren Olney hosts the show; it was syndicated nationwide by PRI and aired in 15 states and Washington, D.C. by Public Radio International. KCRW continues to podcast the program weekly (sometimes more frequently). The program begins with its theme music, a clip from John Coltrane's "A Love Supreme." Olney then introduces the topics for the day's program, followed by a break for
