Illusion of Space and Depth We live in a three-dimensional world of depth. When we look around us, some things seem closer, some further away. The artist can also show the illusion of depth by using the following means: <ul style="color: rgb(0, 0, 0); font-family: 'Times New Roman'; background-color: rgb(255, 255, 255); font-size: medium; "> <li> Size & Vertical Location</li> <li> Overlapping</li> <li> Detail (Aerial or Atmospheric Perspective)</li> <li> Linear Perspective</li> </ul>   <table border="0"> <tbody> <tr> <td valign="top" width="217"> <blockquote>  </blockquote> <img align="top" alt="Pic:depth by size and vertical location" height="123" src="http://www.usask.ca/education/coursework/skaalid/theory/cgdt/designimages/vertical2.gif" width="216" x-claris-useimageheight="" x-claris-useimagewidth="" /> </td> <td valign="top"> <h3> <a name="size"></a>Size & Vertical Location</h3> Since objects in our environment look smaller when they are farther away, the easiest way to show depth is to vary the size of objects, with closer objects being larger and more distant objects being smaller. As well, we perceive objects that are higher on the page and smaller as being further away than objects which are in the forefront of a picture.  </td> </tr> </tbody> </table>   <hr style="color: rgb(0, 0, 0); font-family: 'Times New Roman'; background-color: rgb(255, 255, 255); font-size: medium; " /> <table border="0"> <tbody> <tr> <td valign="top" width="182"> <h3> <a name="overlapping"></a>Overlapping </h3> When objects are partially obscured by other objects in front of them, we perceive them as further back than the covering objects. We do not see them as incomplete forms, just further back. </td> <td> <img align="bottom" alt="Pic:overlapping" height="148" src="http://www.usask.ca/education/coursework/skaalid/theory/cgdt/designimages/overlap2.gif" width="259" x-claris-useimageheight="" x-claris-useimagewidth="" /> </td> </tr> </tbody> </table> <hr /> <table border="0"> <tbody> <tr> <td width="388"> <h3> <a name="detail"></a>Detail (Aerial or Atmospheric Perspective) </h3> <img align="top" alt="Pic:Aerial Perspective" height="316" src="http://www.usask.ca/education/coursework/skaalid/theory/cgdt/designimages/aerial2.jpeg" width="360" x-claris-useimageheight="" x-claris-useimagewidth="" /> Atmospheric perspective uses color and value contrasts to show depth. Objects which are further away generally have less distinct contrast - they may fade into the background or become indistinct dark areas. The foreground objects will be clear with sharper contrast.  Here is a link to Leonardo da Vinci's use of aerial perspective: <a href="http://www.mos.org/sln/Leonardo/InvestigatingAerialP.html">Investigating aerial perspective</a> </td> </tr> </tbody> </table> <hr /> <table border="0"> <tbody> <tr> <td width="285"> <h3> <a name="linear"></a>Linear Perspective (Converging Lines)</h3> <h3> <img align="top" alt="Pic:Linear perspective" height="217" src="http://www.usask.ca/education/coursework/skaalid/theory/cgdt/designimages/linearpersp.jpeg" width="333" x-claris-useimageheight="" x-claris-useimagewidth="" /></h3> Linear perspective is based on the idea that all lines will converge on a common point on the horizon called the vanishing point. You have observed linear perspective when you notice that the lines on the highway appear to meet at a point in the distance. Artists use linear perspective to create a focal point for a picture. Any walls, ceilings, floors or other objects with lines will appear to come together at the horizon line. These lines converging lead our eyes towards that point. Often, the most important object or person in the picture will be located at that point. You can see in the drawing above how all the lines in the drawing seem to lead your eye toward the church in the center back of the drawing. Other types of perspective, such as two-point or multipoint perspective are also used. Two-point perspective, which occurs when you display a building from a corner view, as opposed to a front view, is often used by architects to show a more three-dimensional view of a building. To learn the mechanics of setting up a picture using linear or multipoint perspective check out this site:  </td> </tr> </tbody> </table> We live in a three-dimensional world of depth.
