Linear Perspective


Three-Point

Three-point perspective is used to indicate unusual vantage points and create exaggerated spatial effects. Three-point, sometimes called "bird's eye" or "worm's eye" view, starts out like a two-point drawing: two widely spaced vanishing points are placed on a horizon line; however, a new vertical line is added. At one end of this line is placed the vertical vanishing point. As before, the receding horizontals follow the orthogonals back to the left and right points, but the verticals no longer remain parallel. Instead, they too diminish as they approach the vertical vanishing point.
 

Click any of the diamonds to view the perspective lines between the object and vanishing point. The 3-point perspective diamonds (top and bottom) are available only after selecting both the left and right diamonds, showing the 2-point perspective.
