Linear Perspective is the formal system for drawing three-dimensional
space on a two-dimensional surface, or creating the illusion of
depth.
The Types
There are a few different types of perspective drawing, the two
most basic for representing objects in a space are...
One point Perspective- objects drawn in three-dimension using one
vanishing point on the horizon.
Two point Perspective- objects drawn in three-dimension using two
vanishing points on the horizon.

The Basics
When drawing objects in a space, use the method of drawing
simple shapes to create the more complex forms, also known as
“blocking in”.
- First try to see the object(s) as a combination of simple
shapes.
- How do these shapes relate to the background or the objects
around it?
- Remember one main rule of perspective is, Vertical lines of
objects are always vertical.
- The second rule is that everything in your picture will relate

To understand horizon or vanishing point, imagine a horizontal line
in front of you that cuts right across your line of vision, this is
your eye level or the horizon line. Look at the perspective of the
classroom...
- Notice all horizontal lines above your eye level appear to
slant downward as they go away from you.
- All horizontal lines below eye level, (ex.) table edges, floor
pattern, appear to slant upward.
- Horizontal lines at eye level will have no slant.
- Vertical lines of doorways, windows and walls stay vertical
because they stay the same distance from you throughout their
length.
Three variations of eye level include,
High eye level- looking down at objects from above.
Middle eye level- looking across at objects.
Low eye level- looking up at objects from below.

Vanishing point- A spot where parallel lines appear to meet. All
parallel/horizontal lines going back in space appear to converge at a
point somewhere on the horizon. These points give you an exact method
for determining the angle of each and every receding horizontal line.
Vanishing points can be both on or off the paper, this all depends on
if your view is extreme over or under.
Creating Depth- Illusion of depth is created by devices which mimic
the way the eye sees three-dimensional space.
Overlapping shapes- When two shapes overlap, the eye perceives
one as being behind the other, creating the third dimension.
Diminishing sizes- Same size objects which recede into the
distance appear to get smaller.
Converging lines- sets of parallel lines, like railroad tracks
or phone lines will appear to converge as
they meet the horizon.
Softening edges and contrast- As objects become more distant,
the in between space will often soften               edges and lessen
contrasts-sometimes called aerial perspective.
Ellipses- An ellipse is a circle seen in perspective. Examples are...
bottle, cup, dome, pole, wheel or other cylindrical, spherical or
half spherical objects.
Drawing ellipses
Rule#1-establish your eye level, you need to know whether to make
your ellipse more open (more round) or closed (more flat). We
determine this by how near to, or how far from the eye level the
ellipse is. Which leads to rule #2.
Rule #2- the ellipse closes or flattens out, as it nears your eye
level.
Rule #3- Ellipse ends are always rounded, never pointed, because it’s
a circle turned on its side.
Rule#4- Ellipses are symmetrical- whatever shape one curve has, the
top is just a mirror image of the shape below it.
