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
The Point! take the road indicated by the hand and make their way back to the Land of Point, where they receive a hero's welcome from the land's citizens, and the king. Oblio begins to tell his story but is interrupted by the furious count, who is then silenced by the king. Oblio tells the king and the people of the land that everything has a point, including the Pointless Forest, and himself. Angered, the count pulls off Oblio's pointed hat, but is taken aback when he sees a point on top of Oblio's bare head. Upon this revelation the points of
