Two Point perspective for KS3
Copyright of Stephen J Walsh 2011
Do you remember one point perspective where everything disappeared off to a point
on the horizon?
Here is the horizon at the sea side
The horizon is also known as ‘eye level’ because your eyes are level with it!
Well, two point perspective is even cooler than that, though it can be harder to draw until
you’ve practised.

Like One Point Perspective, Two point has a horizon or ‘eye level’.
Notice how you can only see the top or bottom of some of the boxes?
As you may expect by its name there are TWO vanishing points
Copyright of Stephen J Walsh 2011
Can you see the horizon and two vanishing points on these pictures?
On each picture one of the vanishing points is well off the paper, to the left, beyond our field of vision.
This complex picture also has a horizon and two vanishing points
The horizon on this picture is set deliberately high as if you are looking at it from a first floor window
Can you see how you are looking down on the human figures?
Lets start by doing our own version of this picture.
Copyright of Stephen J Walsh 2011
Draw a 25 mm border around your A4 sheet set to landscape
Draw the horizon at about half way across the whole page
Horizon
We are going to make vanishing points where your border touches the horizon, call them VP1 and
VP2
VP1 VP2
VP1 VP2
In the middle of the horizon draw a vertical line 40mm long that goes halfway above and below the line
VP1 VP2
From the top and bottom of this line LIGHTLY draw radial lines to the Vanishing Points. These are ‘construction lines’are will not be seen in the end.
About 45mm from the first vertical draw a parallel line between the two radials.
VP1 VP2
45
Do the same on the other side but on 35mm away this time. You should start to see the first box now.
VP1 VP2
35
Can you see the first box? Make it clear using strong ‘object lines’.
VP1 VP2
About 20mm above the first vertical line you drew, draw another of the same length. i.e. 40mm. Don’t worry if you go slightly above the border.
VP1 VP2
40mm long
Draw LIGHT radials to the VP’s
VP1 VP2
Draw another vertical directly above the second line you drew to make the edge of the second box.
VP1 VP2
Now LIGHTLY draw a radial to VP2 from the bottom of that line. Don’t worry if it passes through the first box.
VP1 VP2
Now, using your judgement draw another construction line from VP1 to make the bottom of box two.
VP1 VP2
From where this new line crosses the radial draw a vertical line up to make the side of the box. Can you see box two now?
VP1 VP2
Use ‘object lines’ to make box two clear. It does not need to be the same size as box one.
VP1 VP2
Just like we started box two, this time draw a vertical line below the nearest edge of box one.
VP1 VP2
40mm long
Draw the radials to the vanishing points using construction lines.
VP1 VP2
Draw a vertical line between the radials about 35mm parallel to the leading edge we have drawn.
VP1 VP2
From the top of this line draw a radial to VP2 to show the top of box three.
VP1 VP2
Use your judgement to draw a vertical between the radials to make the other side of box three
VP1 VP2
From the top of the vertical draw a radial to meet VP1. You should be able to see box three now.
VP1 VP2
Use ‘object lines to make box three clear.
VP1 VP2
VP1 VP2
Without the construction lines it would look like this. That’s why we draw them LIGHT.

VP1 VP2
Maybe another over here…above and below the horizon
VP1 VP2
How about we squeeze a little one in here?
VP1 VP2
VP1 VP2
VP1 VP2
A big one at the back.?......
How about an L-shaped box up here.?.....
VP1 VP2

VP1 VP2
Room for two small ones down here.?....
VP1 VP2
VP1 VP2
Try strengthening the outer lines of each block like this…..
VP1 VP2
It makes them look 3D. This is called thick and thin line technique.

This drawing was done using the same methods.
• Now for the hard one!! Lets see if we can put together a picture like this one….
See where the horizon and VP’s are?
VP2VP1
Copyright of Stephen J Walsh 2011
Start the horizon a lot higher up this time…we are looking down from a block of flats on the other side of the road
VP2VP1
LIGHTLY draw these two radials for the front corner of the house. I’ve done them in colour to make it easier to see..
VP2VP1
LIGHTLY add a line to show the height of the bungalow and put a radial back to VP1.
VP2VP1
LIGHTLY add a radial from the top of this vertical to VP2
VP2VP1
Put in a vertical to show the depth of the front block.
VP2VP1
LIGHTLY put a radial from VP1 and through the bottom of the last line.
VP2VP1
Now put a radial through the top of the same line.
VP2VP1
Add a vertical to show the end of this block.
VP2VP1
Now put in a radial back to VP2
VP2VP1
Show the height of this wall by LIGHTLY drawing a radial back to VP2
VP2VP1
Use your judgement to put in a vertical to show the end of this part of the building.
VP2VP1
From the top of this new vertical make a LIGHT radial line to VP1 to show the top of the back wall.
VP2VP1
Now LIGHTLY put in this radial to VP2 to show the tops of all the walls
VP2VP1
Next we are going to make an even pitched roof Starting with this wall
To find the centre of this wall LIGHTLY cross the diagonals
Copyright of Stephen J Walsh 2011
From where they cross LIGHTLYproject a vertical line upwards
From where this vertical bisects the top line of the wall put a LIGHT radial line to VP2. Make sure it meets the top of the back wall.
Use your judgement to set the pitch of the roof by drawing from the
walls top corners to this centre line.
Copyright of Stephen J Walsh 2011
From the top of the roof LIGHTLYdraw a radial back to VP2
VP2VP1
Your drawing should look like this by now. Lets put the other end of this pitched roof on.
I’ve zoomed in so you can see.LIGHTLY put this radial in from the top centre of the wall to VP2.
Copyright of Stephen J Walsh 2011
Where this new radial meets the top of the back wall LIGHTLY draw a vertical
Where this vertical meets the top radial of the roof line we can now draw in a diagonal to show the slope of the roof
Joins at this crossing

VP2VP1
I’ve taken out a few construction line so you can see clearly what you’ve got. Lets put a
pitch on the extension roof.
Extension
I’ve zoomed in again. Like last time LIGHTLY put diagonals across the
wall and add a vertical.
Copyright of Stephen J Walsh 2011
This bit is a bit unscientific, but I’m going to leave it to you to judge where the top of the roof is and draw in the diagonals to the top
of this wall
From the top of this new roof draw a radial towards VP1 until it meets
the top of the other roof here
From this crossing point draw a line to the top corner of the walls here.
VP2VP1
You should be able to see something like this now. I’m going to strengthen a couple of lines and fade out some construction.
VP2VP1
Believe it or not this is the basis from which you could produce
something this this
Master copy
VP2VP1
By using the VP’s I could start to put in a porch and step.
VP2VP1
Close up construction on next slide
Here’s the construction for the porch. Can you see how I did it?
Copyright of Stephen J Walsh 2011
I can put in the barge boards and gutters to the roof
VP2VP1
Close up on next page
Here’s a close up of that
Copyright of Stephen J Walsh 2011
Here’s the construction for the chimney
VP2VP1
Close up on next slide
See how it came together using the two VP’s?
Copyright of Stephen J Walsh 2011
How about those windows?
VP2VP1
Close up on next page
Here’s the construction close up
Copyright of Stephen J Walsh 2011
I’ve now made some of the lines solid…..
VP2VP1
Lets remind ourselves of the master copy
VP2VP1
It’s a simple matter to add the paths etc or to make up your own
VP2VP1
Here’s one I’ve made up….
VP2VP1
And here’s the start of my ‘scene’..
VP2VP1
The End…for now
