context_page_description: In painting, photography, graphical perspective and descriptive geometry, a picture plane is an image plane located between the "eye point" and the object being viewed and is usually coextensive to the material surface of the work. It is ordinarily a vertical plane perpendicular to the sightline to the object of interest.
context_section_description: In the technique of graphical perspective the picture plane has several features:
  Given are an eye point O (from oculus), a horizontal plane of reference called the ground plane γ and a picture plane π... The line of intersection of π and γ is called the ground line and denoted GR. ... the orthogonal projection of O upon π is called the principal vanishing point P...The line through P parallel to the ground line is called the horizon HZ
  The horizon frequently features vanishing points of lines appearing parallel in the foreground.
