PerspectiveOne-Point Perspective

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

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.
