One Point Perspective: A drawing has one-point perspective when it contains only one vanishing point on the horizon line. This type of perspective is typically used for images of roads, railway tracks, hallways, or buildings viewed so that the front is directly facing the viewer. ... These parallel lines converge at the vanishing point.
- Horizon Line: The line in a perspective drawing where the sky meets the ground. It also represents the viewer’s eye level. That is, the placement of the line on the picture plane depends on the vantage point of the artist. For example, if the artist is low to the ground, the horizon line is low on the picture plane. You can see the top of an object if it is below eye level, below the horizon line. If an object is above eye level, above the horizon line, you can not see its top.
- Vanishing Point: The point on the horizon line at which lines or edges that are parallel appear to converge.
- Orthogonal Line: Literally, a line which is at right angles to another. In linear perspective drawings, it is the line you draw from the corner of an object to the vanishing point. It establishes the illusion of a perpendicular line going into the distance. Orthogonal lines should always be drawn lightly at first. Usually, most of an orthogonal will be erased.
