Two Point Perspective

Two Point Perspective

Today in class we learned about Two Point Perspective. Students are to create a mechanical drawing using a ruler and drafting triangles to create a school appropriate work that is either three or more letters in length. We will be creating two different versions of your word.

One will be your word on the horizon line, and the other will be either above or below the horizon. If you wish your second drawing can incorporate letters either above, on, and below the horizon to make it look more interesting.

  1. Students please review your notes and the proper steps. They are included below so scroll away!!! :)
  2. This is a mechanical drawing, i.e. no free hand construction (unless students curve their letters).
  3. Vocabulary students should know. Please review:
    1. Horizon Line - This line is a light straight line that helps the student to determine where they would like to place their drawing
    2. Vanishing points - two marks or dots that are equidistant measuring down from the top of the paper along the the right and left edge of the paper
    3. Segment End - These are the two ends of a line
    4. Vertices - Where two lines intersect to form an angle
    5. Vertical line (perpendicular line) - a line that is constructed 90o to the horizon line
    6. Vanishing lines - these lines are constructed by
    7. Face - a surface of a three-dimensional object
  4. Types of 2-Point perspective drawings
    1. Above the horizon

    2. On the horizon:

    3. Below the horizon:

How to construct the project!
  1. Place your paper in landscape position (long side right to left)
  2. Construct Vanishing Points (VP)
    1. Measure the distance from the top left corner to the bottom left corner and place a large mark on the edge of the paper midway between the two corners.
    2. Do the same on the right hand side of the paper .
    3. For example here my paper measures 9” so if I divide this in half I get 4.5”

  3. Construct a light Horizon Line
    1. Draw a straight light line and connect the two Vanishing Points. This will create the horizon line.
      1. step 2.jpg
      2. Note: you do not have to label your drawing with VP or Horizon line this is for clarity only
  4. Construct your first vertical line. You need to make two major design decisions here:
    1. Design decision One:
      1. Decide if the first vertical line will be:
        1. Above the horizon line
        2. On the horizon line
        3. Below the horizon line
    2. Design decision Two:
      1. Decide if the first vertical line (perpendicular line) should be drawn:
        1. Closer to the left vanishing point
        2. In the center of the paper
        3. Closer to the right vanishing point
  5. In my example I place the first vertical line (perpendicular line) above the horizon line and closer to the left vanishing point
    1. step 3.jpg
  6. Construct a vanishing line from each end of the line segment to the vanishing points
    1. step 4.jpg
    2. step 5.jpg
  7. Construct a vertical line (perpendicular line) to the left of your first vertical line
    1. step 6.jpg
  8. Construct a vertical line (perpendicular line) to the right of your first vertical line
    1. step 7.jpg
  9. Construct vanishing lines from the two  line segment ends you just made
    1. step 8.jpg
    2. step 9.jpg
  10. We now have constructed a rectangular prism. From this basic shape you will have to count the number of letters in your word and then create equidistant vertical lines on the right face (or the predominant face).
    1. It is good practice to create your words in 2D first and then use the vanishing points to create the 3D letters.
    2. For example FUN has three letters so the right face is divided into three equal parts
    3. step 10.jpg
  11. On a piece of scrap paper make block letters of your word. For example my word is FUN so my letters will look something like: FUN
  12. Next I need to construct vanishing lines that will help me to develop the F in the first block

    5. Next I like to erase some lines so that I can view the letter more clearly. Notice that I do not erase the vanishing lines in the other blocks. These become guidelines for the other letters I construct. If I was going to make an E or some other letter I have a good start on making those block letters.

    7. Now I need to construct vanishing lines to all segment ends or vertices.

    11. Finally I erase some of my vanishing lines so that the F becomes more clear.
    12. fun9.jpg
    13. Using a similar method as I used to create the “F”, I will next create the U, and N. To create the U, I need to establish vertical lines for the inside of the U, and define the lower part of the U.

    16. Next construct vanishing lines to the segment ends and vertices and then erase any unnecessary lines.
    17. fun12.jpg
    18. Constructing the N, I need to create the vertical lines to define the inner edges of the N. I also need to create the two sloping lines that define the N shape.fun13.jpg
    19. Erase unnecessary lines and then construct vanishing lines to each segment end and vertices.

    21. Finally construct vanishing lines to end segments and vertices and erase unnecessary lines.
