In photography measure
In a projection of a line on the center of crop surface parallel lines and the image plane is known as the point of intersection. On the surface of a set of parallel lines are common ( Vanishing point
), in other words, he is on the surface of infinite parallel lines from the center of projection. A projection center as one horizontal plane parallel to the ground, called it a level or Occlusal surface
. True horizontal plane and image plane intersection is called true horizontal line. On the ground of any parallel line combination point fall line in the true level, so it is also called the horizontal line Line
. The intersection line and the main line as the main point. The main point is on the ground of a group of parallel to the direction of the straight line photography infinity conformation.
