Foreshortening ppt

  1. 1. Using perspective to add depth Marsha R Devine 2009
  2. 2.  Is a term used to describe  Is used when drawing the figure perspective. (or animals) when we rely more on observation & sighting, rather than constructed perspective.  While foreshortening is an important element in linear When you foreshorten an object, perspective, foreshortening you make one part appear closer occurs in other types of two- to you than the other. dimensional representations of three-dimensional scenes, such as ‘oblique parallel projection’ drawings used in CAD.
  3. 3. Examples of various problems in perspective taken from actual drawings which have appeared in Marvel Comics.Compare the thighs of the villain above. We know they are actually the same size, yetin this foreshortened view the right thigh appears much shorter than the left. This isbecause the angle points the leg almost directly at the viewer.Note how the geometric version of the figure at right shows the perspective .
  4. 4.  Sit still and straight! Maintain your position,as a gradual slouch of only an inch alter yourview and change the drawing. Keep your head parallel to the drawingsurface by using an easel, or standing overthe drawing surface to avoid ‘skewing’ yourdrawing. Draw what you see, not what you think itshould look like. It may look strange at first,but will look correct when the drawing iscompleted. Observe part of the figure is hidden,disappearing behind closer elements (thehorses head, or the persons hand). Allowyour lines to reflect this. The Lamentation over the Dead Christ Note that elements closer to you will seem c. 1490 Andrea Mantegnaproportionately larger than further away. Use line weight - something drawn boldlyand using contrast will jump from the page.

  6. 6. Use sighting techniques tocompare proportions andangles of your object orfigure.A ruler or pencil held atarm’s length can be usedas a guide for thecomparisons.
  7. 7. Breaking the figure down into geometric forms can help when applying perspective to the form.Consider how the subject of your drawingwould look in geometric form and thenuse perspective to create theforeshortening – as with the cylinderabove.
