Perspective

  1. 1. Perspective One-Point Perspective Two-Point Perspective
  2. 2. Perspective <ul><li>Is the technique of depicting dimensional objects on a flat surface. </li></ul>
  3. 3. <ul><li>It is helpful to know a few simple principles about perspective before attempting landscapes with buildings. </li></ul>The Artist’s horizon line is located at “Eye Level” There is only One Horizon Line per drawing and everything in that drawing relates to it
  4. 4. Objects appear to grow smaller as they recede into the distance, disappearing altogether at the “Vanishing Point”
  5. 5. Lines that run Parallel to each other like the roof line, foundation and horizontal window edges will appear to grow closer together, and if extended will converge on the horizon at a Single Vanishing Point.
  6. 6. So when would you use one point perspective? <ul><li>One area where one point perspective can be quite useful is for sketching room layouts. </li></ul>
  7. 7. Drawing One-Point Perspective <ul><li>1. Draw a horizon and place a vanishing point (VP) somewhere on this line. </li></ul>
  8. 8. <ul><li>2. Draw a square somewhere beneath the horizon. This will be the front of your box </li></ul>
  9. 9. <ul><li>3. Draw four lines, one from each corner of the square which also pass through the vanishing point. </li></ul>
  10. 10. <ul><li>4. To complete the box, draw in the back horizontal line and side vertical line. </li></ul>
  11. 11. <ul><li>5. To finish the box. Erase vanishing point lines and shade </li></ul>
  12. 12. <ul><li>The Following is a Demonstration on How to Create a One Point Perspective Drawing </li></ul>
  13. 14. There may be more than One Vanishing Point in a composition, each will be located somewhere along the Horizon Line. This would be called a Two-Point Perspective Drawing.
  14. 15. Two Point Perspective <ul><li>Two Point Perspective is a much more useful drawing system than the more simple One Point Perspective. Objects drawn in two point perspective have a more natural look. </li></ul>
  15. 16. <ul><li>In two point perspective the sides of the object vanish to one of two vanishing points on the horizon. Vertical lines in the object have no perspective applied to them. </li></ul>
  16. 17. <ul><li>By altering the proximity of the vanishing points to the object, you can make the object look big or small. </li></ul>Vanishing Points close to the object Vanishing Points far away from the object
  17. 18. Anamorphosis <ul><li>A distorted projection or perspective requiring the viewer to use special devices or occupy a specific vantage point to reconstitute the image. </li></ul>
  18. 19. There are two main types of Anamorphosis: <ul><li>Perspective (oblique) and Mirror (catoptric). </li></ul>Examples of Perspectival Anamorphosis date to the early Renaissance (15th Century), whereas examples of Mirror Anamorphosis occurred at the time of the Baroque (17th century).
  19. 20. <ul><li>With mirror Anamorphosis, a conical or cylindrical Mirror is placed on the drawing or painting to transform a flat distorted image into a three dimensional picture that can be viewed from many angles. </li></ul>
  20. 21. The deformed image is painted on a plane surface surrounding the mirror. By looking uniquely into the mirror, the image appears undeformed. Current in the 1600s and 1700s, this process of Anamorphosis made it possible to diffuse caricatures and scatologic scenes as well as scenes of sorcery for a confidential public.
  21. 22. Today many artists use these techniques to create illusion. Julian Beever creates chalk paintings where he actually includes the pavement and the architectural surroundings which all become part of his illusion.
  22. 23. Art of this style can be produced by taking a photograph of an object or setting at a sharp angle, then putting a grid over the photo, another elongated grid on the footpath based on a specific perspective, and reproducing exactly the contents of one into the other, one square at a time.
  23. 25. Viewed At the Wrong Perspective
