Diagonal Vanishing Point
Overview[edit]
The diagonal vanishing point is used to create square shapes in 2-point perspective.
1. Draw a horizon line and drop a perpendicular line down from it to the Station Point (SP).
2. Add vanishing points such that the lines from the vanishing points to the station point will intersect at a 90° angle.
3. Draw a square with one corner placed at the station point. Draw a line from the station point through the opposite corner of the square and continue the line until it intersects the horizon line. This intersection with the horizon line marks the Diagonal Vanishing Point (DVP).
4. Draw 2 lines that intersect with one of the vanishing points, and another line that intersects the opposite vanishing point.
5. Draw a line from the nearest intersection of the drawn lines to the DVP.
6. Draw a line from the opposite vanishing point through the intersection of the line to the DVP with the other line intersecting the vanishing point. Continue this line until it intersects the line going to the other vanishing point.
7. This line completes a square shape in perspective. All sides would be the same length if the square were moved parallel to the picture plane.
