Exteriors In 2-Point Perspective |
 |
|
When using two point linear perspective, one must look
carefully at the placement of the object. If the object is not perpendicular
and parallel to you and you are looking at it's corner, then you probably
want to work in two point. Sometimes when working in two point perspective
one of the vanishing points is not on the page. You then must approximate
where the point falls by looking at the angles of the object which you are
drawing. The best way to approximate an angle and find a vanishing point in
two point perspective is to first find your horizon line. This is a level
line. By using this level and placing it next to the front corner of the
object one can then see the angle and continue this angle out until it
intersects with the horizon line. After you have found this intersection,
then you have established your vanishing point for all the planes that are
parallel and recede the same direction. Repeat this process for the other
side of your object and all convergence lines will be established. Use the
font edge of an object in two point perspective when you want to scale it.
This is the only constant line in two point because there are no horizontals
on the object to work from. Verticals are always at a 90 degree angle to the
horizon line in one and two point perspective. Hint: Find your horizon line first. Then find out how much distance in proportion to the object's height there is between the horizon line and the front vertical edge of the object. This will help eliminate distortions. |
