Two Point Perspective

Two point perspective is also known as angular perspective and can be observed by standing in front of the corner of a building. From this "street" view we can see the  left and right sides of the building but we can’t see the top or the bottom. We observe two sets of parallel lines receding to two separate vanishing points on the horizon. 

Practice Two Point Perspective:

1. Identify the horizon line and place it on the paper.
2. Draw the nearest edge of the building which will be a perpendicular line bisecting the horizon line. Notice that our building seems to drop below the horizon line. This occurs because the horizon line is at our eye level, not the level of our feet.
3. Note the angle of slope from the top of the nearest edge to the left side horizon to place the first vanishing point. If your vanishing point is located outside of your drawing area you can place scrap paper behind your artwork and locate the vanishing point where it extends beyond the scope of your drawing.
4. Place the vanishing point to the right side of the perpendicular line on the horizon line using the slope on that side of the building which may be different. (Which side of the building has a more dramatic slope to the horizon? Make sure your drawing reflects that.)
5. Draw lines from the top and bottom of your nearest edge to the vanishing points on each side of the line.
6. Draw in vertical edges to your building between the angle lines.
7. Add any other guide lines you require. In the example above lines are added to help place windows and doors.
8. Erase unnecessary guidelines and darken useful lines to complete your building.
