Vanishing point of multipoint perspective, and historian Kirsti Andersen compiled these observations. She notes, in terms of projective geometry, the vanishing point is the image of the point at infinity associated with , as the sightline from through the vanishing point is parallel to . As a vanishing point originates in a line, so a vanishing line originates in a plane that is not parallel to the picture . Given the eye point , and the plane parallel to and lying on , then the vanishing line of is . For example, when is the ground plane and is the horizon plane,
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
