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
Point 5353 Point 5165, Point 5240 and Point 5100, guided their superior 155-millimetre Bofors howitzers with devastating accuracy. Pakistani troops on Point 5353 were first hit with smoke-filled mortar shells, to flush them out of their bunkers, and then with air-burst artillery, which showered down shards of metal at great speed. Well over 40 Pakistanis are believed to have died on Point 5353. Pakistan could not reinforce the troops since the Indian soldiers on Point 5165 and Point 5240 were in a position to hit their supply lines. Point 5353 Point 5353 (also called Point 17561, and Marpo La Peak) is a
