WHAT IS PERSPECTIVE ?
Perspective
in the graphic arts is an approximate representation, on a flat surface (such
as paper), of an image as it is seen by the eye. The two most characteristic
features of perspective are that objects are smaller as their distance from the
observer increases; and that they are subject to foreshortening, meaning that
an object's dimensions along the line of sight are shorter than its dimensions
across the line of sight.
A drawing
has one-point perspective when it contains only one vanishing point on the
horizon line. This type of perspective is typically used for images of roads,
railway tracks, hallways, or buildings viewed so that the front is directly
facing the viewer. Any objects that are made up of lines either directly
parallel with the viewer's line of sight or directly perpendicular (the
railroad slats) can be represented with one-point perspective. These parallel
lines converge at the vanishing point.
Perspective is very important for showing
depth, size-comparison. You see it in everything, everywhere around us and in
the world we live in. Its all perspective and 3-dimensional. It is a way for
you to create 3 dimensional work.
*We are showing you 1 perspective
today. Use a ruler to make a line go from one side to the other (Use a
ruler so yours will be straighter than mine.)
Anywhere on the line, we are going to place our vanishing point. I am
going to place it to the side here (the circle dot that you see). Choose
any spot that you want, and draw a square (use a ruler so they will be way
straighter than mine).
Now connect the vanishing point to the
corners of our square. Now the name of the game is to connect the vanishing
point to the corners of our square.Use
your ruler so the lines will be accurate.
– Draw
a vertical line…make sure this line is touching both the bottom and top lines
(the ones that are headed towards the vanishing point).
–
Then draw a straight line across (as highlighted in red). Make sure that it is
parallel to the one in front of it.
–
You can start erasing the lines that are going towards the vanishing points.
And
there you guy, we have a cube. Pretty simple.
Artists use one-point perspective to show objects face-on.
Most lines are vertical, horizontal, or orthogonal drawn to a single vanishing point.
The Horizon Line is Horizontal, it goes from left to right and is parallel
to the bottom edge of the picture.Represent the viewer’s eye level.
It is the place where the ground and the sky seem to
meet.
You can see the top of an object if it is below eye
level,
Below the horizon line.
If an object is above eye level, above the horizon
line, you can not see it’s top.
Horizontal, it goes from left to right and is parallel to the
bottom edge of the picture.
Vanishing point
The single point on the horizon where all the lines seem to come
together-HAS TO BE ON HORIZON LINE
Horizone line
The place
where the land and the sky meet.
Orthogonal line
Lines that
converge at the vanishing point, in real life.
they are
parallel but only seem to meet at VP on a 2D surface to create the illusion of
depth.
Self Assesment
Can you locate
the Horizon Line?
How did you
determine this?
Can you find
the vanishing point in this picture?
pick up Pencil and Paper
now scroll to check- are your answers right or wrong ?
The red line
is the Horizon Line.
Can you locate the
vanishing point?
Now
Start work with me…..
let's start
Place a dot in the middle of the Horizon Line. This is your vanishing point. In one-point perspective the Vanishing Point, represented is always on the Horizon Line. As things get closer to the Vanishing Point they get smaller and smaller until they appear to vanish.
Draw a square or rectangle in your picture plane.
Now connect three corners of your rectangle or square to the vanishing point. These are orthogonals.
Draw a horizontal line between the two orthogonals where you want your forms to end.
Vertical lines go from the top of the page to bottom of the page and are perpendicular to the bottom edge of the picture. Along with orthogonal and horizontal lines they make up a one-point perspective drawing.
Erase the orthogonals to complete your form.
You now have a 3-D form in one-point
perspective.
Follow
same technic to create buildings and houses.
