1. One Point Perspective By Paula Sadler
All the elements of one-point perspective are concretely realized in this engraving by Albrecht Dürer. The paper on which the picture is to be drawn swings out of the way. The string, kept taut by a weight, is led from the hook (the eye of the ideal observer) to a point on the object being portrayed. Presumably a vertical and a horizontal thread are slid so as to record the point at which the string crosses the picture plane. Then the string is relaxed, the drawing swings back, and that point is marked on the paper. This image (itself drawn in one-point perspective) gives a visual explanation of the principle and should not, I believe, be interpreted as a snapshot of an actual procedure.

2. what are we learning? A brief history of one point perspective
Vocabulary
Horizon line
Vanishing point
Vertical, horizontal, and orthogonal lines
How to start creating a drawing with one point perspective
Final project – Futuristic Cityscape

3. The first signs of One Point Perspective
Florentine sculptor and architect,
Fillipo Brunelleschi, was
the first architect to
use mathematical
perspective in creating
designs for buildings during
the early Renaissance.

4. History (cont.) Before one point perspective, artists
had to guess where the lines of
buildings would go in their
drawings. These drawings
tended to look skewed
and awkward.

5. Examples
Before one point perspective, this image of Saint Florus on the left shows the figures in an awkward pose. It’s almost as if they are about to fall out of their seats.
The image on the right, created by the artist Pieter de Hooch is very grounded. It looks like you can walk right through the door.

6. Vocabulary
Horizon line: where the sky meets the ground, a horizontal line
Vanishing point: the place where all lines meet or “vanish,” it is located on the horizon line

7. Vocabulary (cont.)
Horizontal line: a line that goes left to right, it is parallel to the horizon line
Vertical line: a line that goes up and down, it is perpendicular to the horizon line
Orthogonal line: lines that create the sides of an object in one point perspective, these lines are drawn to the vanishing point

8. LET’S GET STARTED! Draw a horizon line across your paper
Put the vanishing point on the horizon line

9. Draw a square or rectangle on the left side of your paper below the horizon line

10. Create the orthogonal lines by connecting three corners of your square or rectangle to the vanishing point

11. Draw a horizontal line to create the top of your form

12. Draw a vertical line to create the side of your form

13. Erase your remaining orthogonal lines

14. Now for windows and doors!
The windows and doors on the front of the building are made with horizontal and vertical lines
The windows and doors on the side of the building will be made with vertical and orthogonal lines

15. Draw a window and door on the front of your building by using only vertical and horizontal lines.

16. Draw a door on the side of your building by first drawing a vertical line and connecting the top of it to the vanishing point.

17. End the door with another vertical line and erase the remaining orthogonal line.

18. Add a window the same way
Add a window the same way. Start with a vertical line and now connect the top AND bottom to the vanishing point.

19. End it with a vertical line and erase the remaining orthogonal lines.

20. Start drawing more buildings down the side of your street!

21. Begin the right side of your street!

22. EXPERIMENT! HAVE FUN BEING CREATIVE!

23. Final project
We will be creating futuristic one point perspective cityscape.
You may add any futuristic elements you like
We will be using colored pencils to finish our drawings.
