Two-Point Perspective
Perspective
Is the technique of depicting dimensional objects on a flat surface.
It is helpful to know a few simple principles about perspective before
attempting landscapes with buildings.
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
Objects appear to grow smaller as they recede into the distance, disappearing
altogether at the “Vanishing Point”
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.
So when would you use one point perspective?
One area where one point perspective can be quite useful is for
sketching room layouts.
Drawing One-Point Perspective
1. Draw a horizon and place a vanishing point (VP) somewhere on this line.
2. Draw a square somewhere beneath the horizon. This will be the front of your box
3. Draw four lines, one from each corner of the square which also pass through the vanishing point.
4. To complete the box, draw in the back horizontal line and side vertical line.
5. To finish the box. Erase vanishing point lines and shade
The Following is a Demonstration on How to Create a One Point

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.
Two Point Perspective
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.
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.
By altering the proximity of the vanishing points to the object, you can make the object look big or
small.

Anamorphosis
A distorted projection or perspective requiring the viewer
to use special devices or occupy a specific vantage point to reconstitute the image.
There are two main types of Anamorphosis:
Perspective (oblique) and Mirror (catoptric).
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).
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.
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.
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.
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.
