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
Getting to the Point DMC, the sound quality of it was somewhat poor. The song was later covered by Mark Bram, from the band Ruby Topaz, on the Ruby Topaz "Rarities" CD (CD Baby and iTunes). Mark did all the instruments and vocals. All songs written by Jeff Lynne.
