1-Point Perspective (Gridline Method)

One-point perspective:

* All vertical lines are perpendicular to the horizon

* All horizontal lines are parallel to the horizon

* All diagonal lines intersect at the point on the horizon

Basic Concepts:

* PICTURE PLANE： 

The “window” that is represented by the picture.

* STATION POINT：

Represents the eye of the observer. 

It is the camera in a photograph. 

* VANISHING POINT：

Are points on the horizon line where receding line (planes) meet.

* GROUND LINE：

A line that is parallel to the picture plane at the base of the object being described.

* HORIZON LINE：

A theoretical line that represents the eye level of the observer.
