2-Point Perspective - PowerPoint Presentation

Slide1

2-Point Perspective

Edward Hopper

The House by the Railroad Slide2

Vocabulary

Perspective- portraying a three-dimensional object /space on a 2-dimensional surfaceVanishing point (VP)- Using two perspective, parallel lines converge to

two points

somewhere in the distance. This point is called the vanishing point (VP). This gives objects an impression of depth.

Orthogonal

- Parallel lines that converge and recede to the vanishing point (VP).

Horizon Line

– the line in the distance where the earth and sky meetSlide3

So, What is two-point

perspective? Two-point perspective is used when artists want to draw an architectural element from the vantage point of seeing it at an angle.

The viewer is able to see both sides of the architectural element receding towards a common horizon line. Slide4

Why 2-Pt Perspective?

2-Point Perspective is a much more useful drawing system than the simple 1-Pt Perspective. Objects drawn in 2-Pt Perspective have a more natural look.Slide5

Differences in 1-Pt & 2-Pt

In 2-pt 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. (They are drawn VERTICALLY!)

This means that

ALL

horizontal lines are drawn to the vanishing point.Slide6

Let’s compare one-point perspective with

two-point perspective. In

one-point perspective

the view is from straight on and the sides recede to only one vanishing point on the horizon.

In

two-point perspective

, the view is from the corner and the sides recede toward two different vanishing points. Slide7

Here are the steps…..they are not so hard.

Draw a horizon line. This is horizontal line that refers to the point at which the sky meets the land. It also refers to the eye level of the viewer. Remember, the horizon line is equal to your eye level. Since you can have only one given eye level at a time, you can only have one horizon line.

Next place two

vanishing points

fairly far apart on your horizon line. The vanishing point refers to the point at which parallel lines appear to converge on the horizon. Think of railroad tracks that seem to come together on the horizon. Slide9

VANISHING POINT

HORIZON LINE Slide10

You’re doing great!

Now, place a vertical line somewhere on your page that is between the two vanishing points. This line represents the corner of the box you are drawing. Draw from the top and bottom of that vertical line towards both of your points. Slide11

THESE IMAGINARY LINES ARE CALLED

ORTHAGONAL LINES Slide12

YOU ARE ALMOST THERE.

Now draw two lines inside your “V” shape. These represent the back corners of your box. Where you put them is determined by how long or wide you want your box to be. Slide13

This is the tricky part…..

But not too tricky. Now, if your box is below your horizon line (eye level) then that means you should be able to see the top.

To draw the top, draw a line from the top of your left most line to your right vanishing point.

Now draw a line from the top of your right most line to your left most vanishing point.

The lines will cross each other creating the top.

Tip:

If your box is above your horizon line (eye level) then do the exact same thing, except draw from the bottom of your lines instead of the top. Slide14
Slide15

You did it! Now just erase your extra orthogonal lines. Slide16

Let’s see that one more timeSlide17

Practice drawing several boxes at different elevations using two-point perspective. Slide18

Tip

: Keep in mind that everything that you put on the sides of your box, must recede to the correct vanishing point. That way, everything gets smaller at the same rate as it goes away from the eye and looks natural.
